Adjuvant therapy improves survival in pT4aN0 oral cavity squamous cell carcinoma with bone invasion

ObjectiveThe prognostic significance of bone invasion in oral cavity squamous cell carcinoma (OCSCC) after accounting for tumor size, nodal spread, and surgical margins is controversial. The aim of this study is to determine whether patients with pT4aN0 oral cavity squamous cell carcinoma with bone invasion have improved overall and disease-free survival with adjuvant treatment.MethodsWe conducted a retrospective review of medical records from 64 patients with stage pT4aN0 due to mandibular involvement who underwent surgery from 2000 to 2020. Kaplan-Meier analysis compared disease-free survival and overall survival between groups who underwent surgery only versus surgery and adjuvant therapy. The prognostic impact of adjuvant therapy was assessed using multivariate analysis and reported as hazard ratios.ResultsThere were no statistically significant differences in clinicopathologic features or mean follow-up between patients who received surgery only and patients who received surgery with RT/CCRT (radiotherapy/concurrent chemoradiation therapy). 5-year disease-free (42.5% versus 65.9%, p = 0.02) and overall survival (43.6% versus 69.0%, p = 0.014) were improved in groups who received surgery and RT/CCRT. Regression analysis controlling for clinicopathologic characteristics, including tumor size, identified radiation as an independent predictor of improved disease-free survival (HR: 0.04, p < 0.001) and overall survival (HR: 0.10, p < 0.001).ConclusionAdjuvant RT/CCRT in patients with pT4N0 OCSCC with mandibular bone involvement is associated with improved disease-free and overall survival. This association was significant regardless of tumor pathologic features such as size or margin status. These findings may help guide physicians in counseling patients regarding risks and benefits of adjuvant RT/CCRT and inform practice guidelines.     

Limited English proficiency and head and neck cancer outcomes

PurposeLimited English proficiency (LEP) is common among hospitalized patients and may impact clinical care and outcomes. This study aimed to examine the relationship between LEP and clinical oncological outcomes for patients with head and neck cancer (HNC).Materials and methodsA single center retrospective review was conducted including adult patients with squamous cell carcinoma of the head and neck who received treatment with curative intent between January 1, 2014 and July 1, 2019. Clinical data collected included patient demographics and clinical variables. Univariate and multivariate analysis was performed to determine whether there was an association between LEP and demographic and clinical factors.ResultsThere were 477 patients included in the study; 426 (81%) were English proficient (EP) while 51 (10.7%) were LEP. The LEP patients were diagnosed with cancer at a later overall stage (p = 0.03) and less frequently treated with surgery alone compared to English speaking patients (p < 0.001). After adjusting for overall stage and primary site, LEP patients were significantly more likely to receive primary surgical management compared to primary non-surgical management [OR = 2.29 95% CI (0.93, 5.58), p = 0.008]. There was also a significant association between LEP and primary site of tumor (p < 0.01). Kaplan-Meyer curves for overall survival and disease specific survival showed no significant differences between the two cohorts (p = 0.8063 and p = 0.4986, respectively).ConclusionsLEP may impact access to care resulting in more advanced overall tumor stage at presentation and treatment with primary surgery compared to non-surgical management after adjusting for tumor stage and primary site. Interventions to provide better access to care, awareness of HNC in the LEP populations, and earlier detection may improve outcomes for LEP patients.     

Tongue strength,dysphagia questionnaire,pharyngeal secretions and FEES findings in dysphagia management in amyotrophic lateral sclerosis

ObjectiveDysphagia is common in Amyotrophic lateral sclerosis (ALS). ALS shows significant phenotypic variability. It is characterized by progressive weakness and/or spasticity of muscles. Dysphagia symptoms vary. Aspiration is often silent and cognitive dysfunction is common. The purpose of the study was to evaluate tongue strength measurements, dysphagia questionnaire, the presence of pharyngeal secretions, and FEES findings in dysphagia management in ALS.MethodsTwenty-five patients completed the Eating Assessment Tool-10 (EAT-10), had their Maximum Isometric Tongue Pressure (MITP), and endurance measured and underwent Flexible Endoscopic Evaluation of Swallowing (FEES) providing 31 examinations.ResultsOut of 25 patients, 76% were self-reported as dysphagic (EAT-10≥3) with a mean EAT-10 at 14.95 (±7.96). ALS patients had significantly decreased tongue strength (mean MITPanterior: 31.69 ± 17.32kPa). Comparing examinations of dysphagic and non-dysphagic status the mean MITPa of non-dysphagic was significantly greater (52.33 ± 10.97 kPa versus 20.6 ± 12.67 kPa), p<0.001. FEES detected aspiration in 10 out of 31 examinations [Penetration Aspiration Scale(PAS) ≥6]. Aspirator status examinations showed statistically significantly worse cough (p = 0.001), tongue strength (p = 0.001) and endurance (p = 0.003), pharyngeal secretions (p<0.001), velopharyngeal sufficiency (p = 0.006), pharyngeal squeeze (p = 0.009), vocal cords’ movements (p = 0.001), pharyngeal pooling (p<0.001), EAT-10 (p = 0.001) and bulbar subscale of ALS Functioning Rating Scale-Revised (b-ALSFRS-R) scores (p = 0.014) compared to non-aspirator status. Correlation analysis indicated that the feeding status had strong statistically significant correlations with the EAT-10 score (rho = ?0.816), anterior tongue strength (rho = 0.735), secretions (rho = ?0.811), pharyngeal pooling (rho = ?0.712) and PAS (rho = ?0.676) at FEES, and b-ALSFRS-R score (rho = 0.791), all p<0.001. The EAT-10 had strong statistically significant correlations with the MITPa (r = ?0.794, p<0.001), secretions (rho = 0.668, p<0.001), and b-ALSFRS-R score (rho = -0.766, p = 0.001). The FEES findings had strong statistically significant correlations with the anterior tongue strength (pooling: rho = ?0.784), and secretions (PAS: rho = 0.723; pooling: rho = 0.671), all p<0.001. For the questionnaire, tongue strength and pharyngeal secretions, ROC analysis assessed cut-off points and discriminating ability to predict aspiration status (Area Under the Curve: 0.838; 0.845 and 0.93, respectively). EAT-10 with a cut-off at 8 was able to predict aspirator status with a sensitivity of 100% and a specificity of 42.9% (negative predictive value-NPV = 100%). A cut-off value of 22KPa for the MITPa discriminated aspirator status (sensitivity = 80%, specificity = 89.5%, NPV = 89.5%). The quantity of secretions observed upon endoscopy with a cut-off value at 1 was able to predict aspirator status (sensitivity = 90%, specificity = 80%, NPV = 94.1%).ConclusionReduced tongue strength, questionnaire-reported symptoms, pharyngeal secretions, and FESS findings can guide identification of patients with ALS at risk of inefficient and unsafe swallowing.     

Moving to a more restrictive transfusion protocol: Outcomes in head and neck free flap surgery

PurposeTo determine if a more restrictive transfusion protocol results in increased rates of adverse flap outcomes in patients undergoing free tissue transfer.Materials and methodsMixed retrospective and prospective cohort study. Patients who underwent surgery before the protocol change were collected retrospectively. Patients who underwent surgery after the protocol change were collected prospectively.ResultsOf the 460 patients who underwent free tissue transfer, 116 patients in the pre-change cohort (N = 211) underwent transfusion (54.98%) and 78 in the post-change cohort(N = 249) (31.33%) (p < 0.001). The mean number of units transfused was 1.55 + 2.00 in the pre-change cohort, and 0.78 + 1.51 in the post-change cohort (p < 0.001). When separated temporally, the pre-change cohort received significantly more blood transfusions than the post-change cohort in the operating room (33.65% vs 18.07%) (p < 0.01), within 72 h of surgery (35.55% vs 15.66%) (p < 0.001), and after 72 h after surgery to discharge (16.59% vs 8.03%) (p = 0.018017). The rate of flap failure was 6.70% in the pre-change cohort, and 5.31% in the post-change cohort (p = 0.67). In a logistic regression model controlling for potential confounders, transfusion protocol was not significantly associated with flap failure (OR = 1.1080, 95% CI: 0.48–2.54). There were no significant differences between cohorts for medical morbidity, ICU transfer, or death.ConclusionOur data support the conclusion that patients undergoing free tissue transfer to the head and neck can be transfused following the same protocols as other patients, without increasing the rate of flap failure or other morbidities.Level of evidence: 3 (mixed retrospective, prospective cohort study).     

Hypofractionated radiotherapy and surgery compared to standard radiotherapy in early glottic cancer

PurposeEarly-stage glottic laryngeal cancer is treated with surgery or radiotherapy (RT), but limited randomized data exists to support one modality over the other. This study evaluates survival differences in early glottic cancer patients treated with either surgery or RT.Materials and methods14,498 patients with early glottic cancer diagnosed from 2004 to 2015 and treated with surgery or RT were identified in the National Cancer Database. Kaplan-Meier method was used to analyze differences in overall survival (OS) by treatment (surgery vs. RT) and radiation dose fractionation. Cox regression modeling and propensity score-matched (PSM) analysis were performed. Adjusted hazard ratios (aHR) with 95% confidence intervals (95% CI) were computed.ResultsMedian follow-up and median OS for all patients were 49.5 and 118 months, respectively. The estimated 5-year OS for surgery and RT was 77.5% and 72.6%, respectively (P < 0.0001). On multivariate analysis, aHR (95% CI) for surgery compared to RT was 0.87 (0.81–0.94, P = 0.0004). Compared to RT regimen 63–67.5 Gray (Gy) in 28–30 fractions, worse survival was noted for RT regimen 66–70 Gy in 33–35 fractions (aHR 1.15, 95% CI 1.07–1.23, P = 0.0003). When compared with hypofractionated RT (63–67.5 Gy in 28–30 fractions), patients undergoing surgery no longer showed improved OS (aHR 0.94, 95% CI 0.86–1.02, P = 0.154). The finding was confirmed on PSM analysis (surgery aHR 0.95, 95% CI 0.87–1.05, P = 0.322).ConclusionIn early glottic tumors, patients treated with surgery demonstrated improved survival compared to RT, but when hypofractionation was considered, there were no significant differences in OS between patients undergoing surgery or RT.     

Clinical predictors of revision surgery for chronic rhinosinusitis with nasal polyposis within 5-year follow-up

BackgroundChronic rhinosinusitis with nasal polyposis (CRSwNP) remains a difficult-to-cure disease. The aim of this study was to determine the potential long-term predictors of revision sinus surgery for CRSwNP.MethodsProspectively gathered patients with bilateral CRSwNP who received primary endoscopic sinus surgery were enrolled. Clinical variables, including the preoperative Lund-Mackay score (LMS), were collected to clarify possible risk factors for revision surgery within a 5-year follow-up. The symptomatic burden was measured using a 10-cm visual analog scale (VAS) before and 1 year after surgery. Further survival analysis was performed to present the revision-free survival in Kaplan−Meier plotting.ResultsEighty four qualified patients were identified and all of them experienced significant improvement in VAS after primary surgery. The 5-year revision rate was 19.05%, and the mean time of revision surgery was 25.31 ± 17.11 months postoperatively. Nasal allergy (OR = 9.287; p = 0.011) and LMS (OR = 1.29; p = 0.06) were found to be the independent risk factors for revision surgery. The discriminatory power of LMS for revision surgery was acceptable (AUC = 0.79) with the best cutoff point located at LMS > 13.5. Patients with both nasal allergy and LMS≧14 had only half of revision-free survival in comparison to overall survival (38.1% vs. 80.95%, p < 0.001).ConclusionsIn patients with CRSwNP who have concurrent nasal allergy and higher preoperative LMS may indicate an advanced disease status and eventually be in a high risk of revision surgery after a long-term follow-up. An outcome-based staging system will be helpful in the future to improve the prognosis for CRSwNP.     

Role of local flaps in the prevention of soft tissue necrosis after transoral robotic surgery for tonsillar cancer

ObjectiveSoft tissue necrosis (STN) can occur after transoral robotic surgery (TORS) with radiation therapy (RT). We investigated the usefulness of local flap reconstruction for preventing STN after TORS in patients with tonsillar cancer.MethodsThis case-control study retrospectively reviewed clinicopathological data of patients who underwent TORS for tonsillar cancer at a tertiary referral center. The incidence of STN was compared in patients who underwent secondary intention healing or local flap reconstruction, and factors predicting STN were identified.ResultsSTN occurred in 20 (25%) of 80 patients in the study. The incidence of STN was higher in the secondary intention healing than the flap reconstruction group. Mucositis grade (odds ratio [OR] 3.694, p = 0.02), RT dose (OR 4.667, p = 0.001), and secondary intention healing (OR 14.985, p = 0.035) were predictive factors for STN.ConclusionFlap reconstruction can prevent STN after TORS with RT in patients with tonsillar cancer. The use of local flaps preserves the minimally invasive nature of TORS.     

Malignant head and neck paragangliomas: Treatment efficacy and prognostic indicators

Purpose

Malignant head and neck paragangliomas (MHNPs) are rare and occur in 6%–19% of all HNPs. We sought to identify predictors of survival and compare efficacy of treatment modalities to inform management of this rare disease.

Materials and methods

We performed a retrospective cohort study of MHNP cases in the National Cancer Institute Surveillance Epidemiology and End Results database (SEER) from 1973 to 2009. We identified 86 patients with MHNP who had documented regional or distant tumor spread with a median follow-up of 74 months. We used Cox proportional hazard models to assess the significance of demographic factors and treatment on five-year overall survival.

Results

The most common treatment was surgery alone (36.0 %), followed by surgery with adjuvant radiation (33.7%). Five-year overall survival was 88.1% for surgery alone and 66.5% for adjuvant radiation (p = 0.2251). In univariate analysis, regional (vs. distant) spread (HR 0.23, p < 0.0001), surgery alone (HR 0.29, p < 0.0001) and primary site in the carotid body (HR 0.32, p = 0.006) conferred significant survival advantage whereas age > 50 (HR 4.04, p < 0.0001) worsened survival. Regional (vs. distant) spread (HR 0.42, p = 0.046) and age > 50 (HR 2.98, p = 0.005) remained significant in multivariate analysis. In patients with regional-only disease, five-year overall survival was 95.4% for surgery alone compared to 75.6% for surgery with radiation (p = 0.1055).

Conclusions

This is the largest and most contemporary series of MHNP patients. Age and tumor stage are significant factors in predicting survival. Surgical resection significantly improves survival outcomes. From this analysis, the value of adjuvant radiation is not clear.     

The value of tracheostomy of critically ill COVID-19 patients - A multicentral study

PurposeTracheostomy is an aerosol-generating procedure, thus performing it during the COVID-19 pandemic arises considerations such as the most appropriate timing and the patients to whom it is suitable. Medical teams lack sufficient data to assist determining whether or not to conduct tracheostomy, its short- and long-term implications are not fully understood. This study aims to shed light on the critically ill COVID-19 patients that require tracheostomy, and to investigate its value.MethodsA retrospective multicentral case-control study of 157 hospitalized critically ill COVID-19 patients, among whom 30 patients went through tracheostomy and consisted of our study group.ResultsThe mean age was similar between study and control groups (68.9 ± 12.7 years vs 70.5 ± 15.8 years, p = 0.57), as well as comorbidity prevalence (56.7% vs 67.7%, p = 0.25). Patients in the study group were hospitalized for longer duration until defined critically ill (5 ± 4.3 vs 3 ± 3.9 days; p = 0.01), until admitted to the intensive care unit (6 ± 6.6 vs 2.5 ± 3.7 days respectively; p = 0.005), and until discharged (24 ± 9.7 vs 10.7 ± 9.1 days, p < 0.001). Mortality rate was lower in the study group (30% vs 59.8%, p = 0.003). Kaplan Meier survival analysis revealed a statistically significant difference in survival time between groups (Log rank chi-sq = 20.91, p < 0.001) with mean survival time of 41 ± 3.1 days vs 21 ± 2.2 days. Survival was significantly longer in the study group (OR = 0.37, p = 0.004).ConclusionTracheostomy allows for more prolonged survival for gradually deteriorating critically ill COVID-19 patients. This should be integrated into the medical teams' considerations when debating whether or not to conduct tracheostomy.     

Factors contributing to hearing impairment in patients with cleft lip/palate in Malaysia: A prospective study of 346 ears

ObjectiveTo determine the factors contributing towards hearing impairment in patients with cleft lip/palate.MethodA prospective analysis was conducted on 173 patients (346 ears) with cleft lip and palate (CL/P) who presented to the combined cleft clinic at University Malaya Medical Centre (UMMC) over 12 months. The patients' hearing status was determined using otoacoustic emission (OAE), pure tone audiometry (PTA) and auditory brainstem response (ABR). These results were analysed against several parameters, which included age, gender, race, types of cleft pathology, impact and timing of repair surgery.ResultsThe patients' age ranged from 1–26 years old. They comprised 30% with unilateral cleft lip and palate (UCLP), 28% with bilateral cleft lip and palate (BCLP), 28% with isolated cleft palate (ICP) and 14% with isolated cleft lip (ICL). Majority of the patients (68.2%) had normal otoscopic findings. Out of the 346 ears, 241 ears (70%) ears had passed the hearing tests. There was no significant relationship between patients' gender and ethnicity with their hearing status. The types of cleft pathology significantly influenced the outcome of PTA and ABR screening results (p < 0.001). There was no significant difference between the repaired and unrepaired cleft groups and the outcome of hearing tests. However, hearing improvement occurred when palatal repair was performed at the age of <1year old (OR = 2.37, CI 1.2 = 4.6, p = 0.01).ConclusionMajority of the cleft patients had normal hearing (70%). Hearing threshold varied significantly between the different types of cleft pathology. Surgery conferred no significant impact on the hearing outcome unless surgery was performed at the age of <1 year old.     

Cost-analysis of in-office versus operating room sialendoscopy: Comparison of cost burden and outcomes

PurposeOffice-based procedures in otolaryngology are increasingly utilized to increase efficiency, reduce cost, and eliminate risks associated with surgery. Gland-preserving surgical management of sialadenitis and sialolithiasis are often performed in the operating room, although many surgeons are moving this practice to clinic. We aim to determine the difference in patient charges and perioperative outcomes for salivary gland procedures performed in the clinic versus the OR.MethodsRetrospective series of patients presenting with sialolithiasis, acute or chronic sialadenitis, and stricture between 2010 and 2019. Demographics, perioperative variables, setting, and charge data were collected.Results528 patients underwent operative intervention (n = 427 office, n = 101 OR). Cohort demographics were comparable. Sialolithiasis was the most common presenting diagnosis in both cohorts. Both cohorts had similar rates of complete (p = 0.09) and partial (p = 0.97) response to treatment. A higher percentage of patients in the OR group reported no improvement (21.4 vs 12.2%, p = 0.034). Overall complications were similar (p = 0.582). Mean charges were statistically greater in the OR ($5560.35 OR vs $1298.33 office, p < 0.001). Operative time was significantly reduced in the office group (21.8 min vs 60.85 min, p < 0.001).ConclusionsAppropriately selected patients can be successfully treated in outpatient clinic without compromising patient safety or quality while significantly reducing the financial burden to patients and the healthcare system.     

Does neck dissection affect post-operative outcomes in parotidectomy? A national study

ObjectiveTo characterize post-operative complications in parotidectomy with neck dissection.MethodsPatients age ≥ 18 receiving a parotidectomy or parotidectomy with neck dissection between 2005 and 2017 were eligible for inclusion. Patients with unknown demographic variables were excluded. Univariate and multivariable logistic regression analyses were performed.ResultsA total of 13,609 parotidectomy patients were analyzed, 11,243 (82.6%) without neck dissection and 2366 (17.4%) with neck dissection. Both length of surgery (mean minutes ± standard deviation [SD] = 335.9 ± 189.2 vs. 152.9 ± 99.0, p < 0.001) and length of hospital stay (mean days ± SD = 3.90 ± 4.76 vs. 1.04 ± 2.14, p < 0.001) were greater with dissection. 13.9% of parotidectomies with neck dissection and 3.5% without dissection (p < 0.001) had at least one complication, which remained significant after multivariable adjustment (Odds Ratio[OR] = 1.565 (95%CI = 1.279–1.914), p < 0.001). The increase in post-operative complications was predominately driven by an increased transfusion rate (7.4% vs. 0.5%, p < 0.001). Multivariable analysis also demonstrated no significant difference in rates of returning to the operating room (OR = 1.122 (95%CI 0.843–1.493), p > 0.05) or rates of readmission (OR = 1.007 (95%CI 0.740–1.369), p > 0.05). Parotidectomy with neck dissection was more likely to be inpatient (OR = 4.411 (95%CI 3.887–5.004), p < 0.001) and to be ASA class 3 (OR = 1.367 (95%CI 1.194–1.564), p < 0.001).ConclusionsNationwide data demonstrates that parotidectomy with neck dissection is associated with increased rates of post-operative complications; however, neck dissection did not significantly impact readmission or reoperation rates. These findings indicate that neck dissection is a relatively safe addition to parotidectomy and provide novel evidence in the management of parotid malignancies.     

Evaluation of emergence agitation after general anaesthesia in rhinoplasty patients: Inhalation anaesthesia versus total intravenous anaesthesia

BackgroundEmergence agitation (EA) is a clinical condition that occurs early in recovery from general anaesthesia, and reduces patient comfort. The aim of this study was to compare the effects of low-flow sevoflurane anaesthesia and total intravenous anaesthesia (TIVA) on agitation in rhinoplasty patients, and to determine the frequency of EA in low flow sevoflurane anaesthesia after rhinoplasty.Material and methodsA total of 90 rhinoplasty patients, under general anaesthesia were included in this prospective randomised study. After induction of anaesthesia, propofol infusion was initiated in the TIVA group (n = 45), and sevoflurane was administered in the SEVO group with a fresh gas flow of 1 l/min and MAC (minimum alveolar concentration) 1–1.1 (n = 45). Early emergence times, Richmond agitation-sedation scale (RASS), Boezaart scale, Likert scale and incidences of nausea/vomiting were recorded at the end of surgery.ResultsEarly emergence time was significantly shorter in the TIVA group, than in the SEVO group (p < 0.001). İntraoperative bleeding was significantly lower in the TIVA group, than in the SEVO group (p = 0.005), and surgical field image quality and surgeon satisfaction were better in the TIVA group (p = 0.016, p < 0.001). The ratio of patients with RASS > +1 for all patients was 35.6% at 0 min, postoperatively. This rate was 12.2% (n = 11) in the TIVA group, and 23.3% (n = 21) in the SEVO group (p = 0.028).ConclusionsIn rhinoplasty, TIVA caused shorter early emergence times, less bleeding, high surgeon satisfaction, and lower EA scores when compared with low flow sevoflurane anaesthesia.     

Facility volume and survival: Human papilloma virus positive oropharyngeal squamous cell carcinoma

BackgroundTo analyze the impact of facility volume on survival for human papilloma virus positive oropharyngeal squamous cell carcinoma (HPV+ OPSCC) patients.MethodsPatients treated for HPV+ OPSCC from 2010 to 2017 were queried from the National Cancer Database. Facilities of average annual case volume <50th percentile were categorized as low-volume (LV) and >95th percentile as high-volume (HV).Results11,546 were included, with 10,305 patients (89.3 %) treated at LV and 1241 (10.7 %) at HV facilities. A greater proportion of cases involving resection of base of tongue and lingual tonsil were treated at HV (30.3 %) compared to LV (22.3 %) facilities (p < 0.001). Patients treated at a HV facility had greater percentage of clinical T4 (11.2 % vs. 8.6 %, p = 0.001) and N+ disease (90.5 % vs. 85.7 %, p < 0.001) patients. Survival analysis showed no statistically significant difference between five-year overall survival rates by facility volume (p = 0.388) for all patients. On multivariable analysis, facility volume was not associated with survival (HR: 0.968 [0.758–1.235], p = 0.791). These trends were found for both patients undergoing primary surgery or chemoradiotherapy.ConclusionOur data indicates that patients with HPV+ OPSCC do not experience a survival benefit with treatment at HV facility, suggesting these patients may be adequately treated at LV centers.     

Characteristics and outcomes associated with anxiety and depression in a head and neck cancer survivorship cohort

PurposeTo assess the prevalence and predictors of mental health disorders (MDHs) among head and neck squamous cell carcinoma (HNSCC) survivors, and the association with health-related quality of life (HRQOL), pain, and survival outcomes.Materials and methodsThis was a retrospective, cross-sectional study of HNSCC survivors surveyed at an outpatient oncology clinic from May 2012 through July 2016.ResultsAmong 198 HNSCC survivors, 21% reported a MHD. Female sex (OR 6.60, 95% CI 2.08 to 20.98; p = 0.001) and Medicare insurance status (OR 4.95, 95% CI 1.52 to 16.11; p = 0.008) were significant predictors of reporting a MHD in the fully adjusted model. Patients reporting a MHD reported significantly worse pain (p < 0001) and worse HRQOL on the PROMIS Physical (p < 0.001), PROMIS Mental (p < 0.001), and FACT-GP (p < 0.026) questionnaires. Diagnosis of a MHD was not correlated with 5-year OS (74% vs. 84%; p = 0.087).ConclusionInitiatives for early identification and intervention of MHDs as part of survivorship initiatives may engender clinically meaningful outcomes in head and neck cancer.     

Myringoplasty in children

BackgroundTympanic membrane perforation (TMP) may be caused by acute and chronic otitis media, trauma and iatrogenic reasons. The goal of myringoplasty is to achieve a dry, self-cleansing ear with intact TM while preserving hearing. Literature review of myringoplasty outcome demonstrates results with different success rates and affecting factors.ObjectivesThe aim of this study was to evaluate TMP closure (TMPC) rate and hearing improvement and to assess the effect of clinical and surgical parameters on residual and recurrent perforation.Materials and methodsRetrospective chart analysis of pediatric patients who underwent myringoplasty between the years 2000–2015. Closure success rate and hearing improvement were evaluated. The influence of age and clinical and surgical variables over TMPC rate and recurrent perforation were examined.ResultsOur study cohort consisted of 165 myringoplasties in 151 children, with a mean age of 11.7 years (R = 4.8–17.9, Me = 12.0).At one month follow-up (FU) TMPC rate was 88% (145/165). Among patients with successful TMPC a mean improvement of air bone gap (ABG) and speech reception threshold (SRT) were 9.9 dB, p < 0.001 and 9.4 dB, p < 0.001, respectively.58/145 (40%) patients with initial closure had a minimum FU of 6 months (Me = 12.0), during which time 8/58(13.8%) had a recurrent perforation. Surgery before 9 years of age was the only factor correlated with failed initial closure (p = 0.03) and recurrent perforation (p = 0.02).ConclusionsPediatric myringoplasty is associated with high TMPC rate. Hearing improvement is to be expected in most hearing impaired patients. Age under 9 years is associated with significantly higher rates of persistent and recurrent perforation.     

Repeated video head impulse testing in patients is a stable measure of the passive vestibulo-ocular reflex

ObjectivesThe video head impulse test (vHIT) is used as a measure of compensation yet it’s stability in patients with vestibular pathology is unknown.Methods144 patients (n = 72 female, mean 54.46 ± 15.8 years) were grouped into one of three primary diagnoses (Peripheral, Central, or Mixed). Subjects were further categorized based on sex (male versus female), ear (left versus right; ipsilesional versus contralesional), age (six groups ranging from 19 to 84 years), and duration between visits (five groups, mean 191.46 ± SE 29.42 days, median 55.5 days). The gain of the VOR during passive head rotation was measured for each semicircular canal (horizontal, anterior, posterior).ResultsThere was no difference in the VOR gain within any semicircular canal between the two visits (horizontal: p = 0.179; anterior: p = 0.628; posterior: p = 0.613). However, the VOR gain from the horizontal canals was higher than the vertical canals for each visit (p < 0.001). Patients diagnosed with peripheral vestibular pathology had significantly lower (p ≤ 0.001) horizontal semicircular canal gains at each visit. There was no difference in VOR gain between sex (p = 0.215) or age groupings (p = 0.331). Test-retest reliability of vHIT in patient subjects is good (ICC = 0.801) and the VOR gain values across two separate visits were significant and positively correlated (r = 0.67) regardless of sex, ear, age, or duration between visits.ConclusionThe vHIT is a stable measure of VOR gain over two different times across a variety of vestibular patients with no influence of age or sex.     

Investigation of the protective effects of intraperitoneal melatonin in rats receiving laryngeal radiotherapy

ObjectivesTo examine the protective effects of melatonin on laryngeal radiation damage.Materials and methods31 rats were divided into 4 groups as follows: 1) the control (C) group (n=7), was only injected with intraperitoneal ethanol solution; 2) the melatonin (M) group (n=8), was injected intraperitoneal melatonin solution with 5 mg/kg; 3) the radiotherapy (RT) group (n=8) was given laryngeal radiation after intraperitoneal injection of ethanol solution; 4) the M + RT group (n=8), RT was given 30 minutes after 5 mg/kg dose of melatonin solution was injected. Drug and radiation applications were continued for 5 days. The weight changes of the rats were recorded. At the end of the study, inflammation, neutrophil migration and lymphoid aggregates, collagen distribution, laryngeal glandular structures and biochemical analysis of laryngeal tissues [malondialdehyde (MDA), total oxidant status (TOS) and total antioxidant status (TAS)] were determined.ResultsIn the M+RT group, the first day and the 30th weight differences were significantly increased when compared with the RT group (p=0.050). Inflammation, neutrophil migration, lymphoid aggregate, disorganized collagen distribution and loss of glandular tissues were found statistically more in the RT group than in the C group (p<0.05). MDA and TOS levels were in the M + RT group exhibited better values than they did in the RT group (p<0.05). TAS levels was markedly increased in the M + RT group than in the RT group (p<0.001).ConclusionAdministration of melatonin to rats prior receiving laryngeal radiation, decreases the level of oxidative stress markers and increases the level of anti-oxidative markers.     

Audiological and vestibular symptoms following SARS-CoV-2 infection and COVID-19 vaccination in children aged 5–11 years

PurposeThe present study assessed the prevalence of audio-vestibular symptoms following SARS-COV-2 infection or COVID-19 vaccination among children, comparing the two groups. A further aim was to evaluate whether children with pre-existing unilateral hearing loss were more prone to adverse events.Materials and methodsThis retrospective study included children aged 5–11 years with normal hearing or a proven history of unilateral hearing loss who contracted SARS-CoV-2 or received two doses of COVID-19 vaccine. Tinnitus, hyperacusis, aural fullness, otalgia, otorrhea, new-onset hearing loss, vertigo and dizziness were investigated as possible complications of SARS-CoV-2 infection or the COVID-19 vaccine.ResultsThis study included 272 children (143 boys, 129 girls), with a mean age of 7.8 ± 2.3 years. Among these, 120 were affected by pre-existing unilateral hearing loss.The most common audio-vestibular symptoms reported by children following SARS-CoV-2 infection and COVID-19 vaccination were aural fullness (33/132, 25 %) and dizziness (5/140, 3.6 %), respectively. All symptoms following COVID-19 vaccination resolved within 24 h.Compared to children who received the COVID-19 vaccine, those infected with SARS-CoV-2 had a higher prevalence of tinnitus (p = 0.009), hyperacusis (p = 0.003), aural fullness (p < 0.001), otalgia (p < 0.001), otorrhea (p < 0.001), and vertigo (p = 0.006). Two girls also experienced new-onset unilateral sensorineural hearing loss following SARS-CoV-2 infection.Children with a known history of unilateral hearing loss did not have a higher prevalence of audio-vestibular symptoms than children with normal hearing.ConclusionsOur results suggest that the COVID-19 vaccine is safe and can be recommended for children with unilateral hearing loss without fear of possible audio-vestibular sequelae.
