Effects of cavity reconstruction on morbidity and quality of life after canal wall down tympanomastoidectomy

Introduction

Canal wall down tympanomastoidectomy is commonly used to treat advanced chronic otitis media or cholesteatoma. The advantages of canal wall down mastoidectomy are excellent exposure for disease eradication and postoperative control of residual disease; its disadvantages include the accumulation of debris requiring life-long otological maintenance and cleaning, continuous ear drainage, fungal cavity infections, and the occurrence of dizziness and vertigo by changing temperature or pressure.

Spontaneous healing of the tympanic membrane after traumatic perforation in rats

The most common etiologies of tympanic membrane perforation are infections and trauma.ObjectiveThe objective of the present study was to assess the healing of traumatic tympanic membrane perforation in rats.MethodsThe tympanic membrane from male Wistar rats was perforated in the anterior and posterior portions to the handle of the malleus. Five tympanic membranes were evaluated 3 days after tympanic perforation; 5 after 5 days; 5 after 7 days; 3 after 10 days; and 4 after 14 days. The tympanic membranes were submitted to histopathological evaluation after hematoxylin–eosin staining.ResultsTympanic membrane closure occurred at about 7–10 days after injury and the healing process was complete by day 14. The proliferative activity of the outer epithelial layer was present close to the handle of the malleus and to the tympanic annulus.ConclusionThe spontaneous healing process of the tympanic membrane starts from the outer epithelial layer, with later healing of the lamina propria and the mucosal layer.     

Factors influencing the quality of life of children with cochlear implants

IntroductionThe multidimensional impact of hearing loss on the various demands of life in children using cochlear implants is represented by variables that can influence the hearing, language and quality of life outcomes of this population.ObjectiveTo evaluate the factors influencing the quality of life of children with cochlear implantation, considering age, hearing age, age at evaluation, hearing skills, spoken language, family degree of receptiveness, schooling and socioeconomic status of the parents.MethodsParticipated 30 children using cochlear implants, aged 6 to 12 years and their respective parents. The children were evaluated by the categories auditory performance, by language category, and by the children with cochlear implants: perspectives parents questionnaire. Parents were assessed by the family involvement scale.ResultsThe cochlear implant impacted the quality of life of the children, with more significant results on the increase of the social relations domain and the decrease of the family support domain. Overall, the increase of the age in the evaluation, better hearing and language skills, the mother's level of schooling and the family receptiveness correlated with the quality of life of children with cochlear implants.ConclusionThe influencing factors that correlated with the quality of life of the implanted children were the child's older age at the evaluation, the better hearing and language skills, the mother's level of schooling and the family receptiveness.     

Disease-specific quality of life after septoplasty and bilateral inferior turbinate outfracture in patients with nasal obstruction

Introduction

Septal deviations might cause nasal obstruction and negative impact on the quality of life of individuals. The efficacy of septoplasty for treatment of septal deviation and the predictors of satisfactory surgical outcomes remain controversial. Technical variability, heterogeneity of research samples and absence of a solid tool for clinical evaluation are the main hindrances to the establishment of reliable statistical data regarding the procedure.

Use of the long-term quality of life assessment in the decision to indicate surgery in patients with chronic rhinosinusitis

IntroductionQuality-of-life questionnaires have been used to support decision-making in patients with chronic rhinosinusitis in the past decade. The choice of treatment in practice, however, also considers the patient's decision.ObjectiveTo assess the long-term quality of life of patients with chronic rhinosinusitis who decided to avoid surgery.MethodsThis is a prospective longitudinal study with a group of patients with chronic rhinosinusitis, with and without indication for surgery, with application of the questionnaire SNOT-22 in two periods: between 2011 and 2012 and between June and August 2016, via email.ResultsData were collected from 42 patients, of which 13 presented indications for surgery and 29 were not indicated for surgery. The average quality of life score was 42.1 (±16.4) in the group with an indication for surgery and 40.6 (±23.4) in the group without this indication, p = 0.84. All the patients were assessed by a single doctor with blinding in relation to the initial score. No differences were detected between the groups. The impact of the chronic rhinosinusitis was reduced even among the patients with the indication for surgery. Both groups scored over 40.ConclusionThis study can help predict the impact of the chronic rhinosinusitis over time and better adjust expectations with non-surgical treatment.     

The influence of standardized dry ivy leaf extract on the proportion of nasal secretion after post-septoplasty nasal packing removal

IntroductionAfter post-septoplasty nasal packing removal, a certain proportion of nasal secretion occurs, leading to local and sometimes systemic infections.ObjectiveThe aim was to determine if standardized dry ivy leaf extract application after nasal packing removal influences the reduction of nasal secretion and diminish the occurrence of local infections.MethodsThe study included 70 post-septoplasty patients (divided into two equal groups) whose nasal packing was removed on the third day after the procedure. Group I was treated with standardized dry ivy leaf extract syrup along with regular nasal irrigation for the five days after the nasal packing removal whereas the Group II had only nasal lavage. On the sixth day after nasal packing removal, the quantity of nasal secretion was determined using a visual analog scale and nasal endoscopic examination.ResultsThe group treated with standardized dry ivy leaf extract syrup had significantly lesser nasal secretion both by subjective patients’ assessment (p < 0.001) and by nasal endoscopic examination (p = 0.003). The post-surgical follow up examination on the sixth day after nasal packing removal showed no development of local infection in the Group I, while in the Group II a local infection was evident in five patients (14.29%) and antibiotic therapy was required.ConclusionThe use of the standardized dry ivy leaf extract after nasal packing removal significantly lowers the proportion of nasal secretion.     

Usefulness of autologous cartilage and fibrin glue for the prevention of septal perforation during septal surgery: a preliminary report

OBJECTIVES: Septal surgery is one of the most common causes of nasal septal perforation. In cases in which a septal mucosal defect at the corresponding area has occurred, autologous cartilage is usually inserted between the injured mucosal flaps. In addition, we applied fibrin glue to the margins of injured mucosal surface to fix the inserted cartilage and to promote mucosal regeneration. The aim of this study was to evaluate the efficacy of this method in the prevention of nasal septal perforation. STUDY DESIGN: Retrospective analysis of medical records. METHODS: A total of 463 septal surgeries were performed between March 2003 and August 2005. Septal mucosal defect at the corresponding area occurred in 34 patients. In group 1 (23 patients), septal or auricular cartilage was inserted between the injured mucosal flaps. In group 2 (11 patients), septal or auricular cartilage was inserted, and fibrin glue was applied on the mucosal margins of cartilage insertion site. We compared the perforation rate between the two groups. RESULTS: In group 1, nasal septal perforation occurred 8 of 23 (34.8%) patients, and in group 2, 1 of 11 (9.1%) patients experienced perforation. Although the occurrence rate of perforation was significantly lower in group 2, statistical significance between the two groups could not be established because of the small number of patients who experienced septal perforation. CONCLUSION: The application of fibrin glue at the bilaterally injured mucosal surface after cartilage insertion is thought to be very useful as a preventive measure of nasal septal perforation. We report these results as preliminary data for further study to determine the usefulness of fibrin glue in the prevention of nasal septal perforation.

Development and validation of the protocol for the evaluation of voice in patients with hearing impairment (PEV-SHI)

IntroductionThe voice of individuals with hearing impairment has been widely described, and can be compromised in all levels of the phonatory system.ObjectiveTo develop and validate an instrument for evaluating the voice of this population.MethodsThe instrument underwent the validation steps suggested by the Scientific Advisory Committee of the Medical Outcomes Trust. The study sample consisted of seventy-eight Brazilian people with cochlear implants (experimental group) and 78 individuals with normal hearing (control group), divided in groups by age range — children from 3 to 5 years; children from 6 to 10 years and adults from 18 to 46 years. The study sample participated in a voice recording of the sustained vowel /a/, connected speech and spontaneous conversation, in which three voice specialists rated using the proposed instrument. It consists of visual-analog scales of suprasegmental aspects, respiratory-phonatory coordination, resonance, phonation, additional parameters and general vocal perception.ResultsEvaluation by an expert committee and a pilot test established content validity. Reliability measures showed excellent test-retest reproducibility for the majority of the parameters. Analysis with the ROC curve showed that perceptual evaluation with the sustained vowel did not strongly differentiate individuals with cochlear implants from those with normal hearing, and the parameter “speech rate” did not differentiate the groups at all. For the connected speech and spontaneous conversation, the majority of the parameters differentiated the experimental group from the control group with an area under the curve ≥0.7. The cutoff values with maximum specificity and sensitivity were 30.5 for mild, 49.0 for moderate and 69.5 for intense deviation.ConclusionsThe protocol for the evaluation of voice in subjects with hearing impairment, PEV-SHI, is a reliable and useful tool for assessing the particularities of the voice of individuals with hearing impairment treated with cochlear implants and can be used in research and clinical settings to standardize evaluation and facilitate information exchange among services.     

Prognostic role of resection margin in open oncologic laryngeal surgery: survival analysis of a cohort of 139 patients affected by squamous cell carcinoma

IntroductionThe treatment of laryngeal squamous cell carcinoma needs accurate risk stratification, in order to choose the most suitable therapy. The prognostic significance of resection margin is still highly debated, considering the contradictory results obtained in several studies regarding the survival rate of patients with a positive resection margin.ObjectiveTo evaluate the prognostic role of resection margin in terms of survival and risk of recurrence of primary tumour through survival analysis.MethodsBetween 2007 and 2014, 139 patients affected by laryngeal squamous cell carcinoma underwent partial or total laryngectomy and were followed for mean of 59.44 ± 28.65 months. Resection margin status and other variables such as sex, age, tumour grading, pT, pN, surgical technique adopted, and post-operative radio- and/or chemotherapy were investigated as prognostic factors.Results45.32% of patients underwent total laryngectomy, while the remaining subjects in the cohort underwent partial laryngectomy. Resection margins in 73.39% of samples were free of disease, while in 21 patients (15.1%) anatomo-pathological evaluation found one of the margins to be close; in 16 subjects (11.51%) an involved resection margin was found. Only 6 patients (4.31%) had a recurrence, which occurred in 83.33% of these patients within the first year of follow-up. Disease specific survival was 99.24% after 1 year, 92.4% after 3 years, and 85.91% at 5 years. The multivariate analysis of all covariates showed an increased mortality rate only with regard to pN (HR = 5.043; p = 0.015) and recurrence (HR = 11.586; p = 0.012). Resection margin did not result an independent predictor (HR = 0.757; p = 0.653).ConclusionsOur study did not recognize resection margin as an independent prognostic factor; most previously published papers lack unanimous, methodological choices, and the cohorts of patients analyzed are not easy to compare. To reach a unanimous agreement regarding the prognostic value of resection margins, it would be necessary to carry out meta-analyses on studies sharing definition of resection margin, methodology and post-operative therapeutic choices.     

Sequential bilateral cochlear implant: results in children and adolescents

IntroductionThe use of the bilateral cochlear implants can promote the symmetrical development of the central auditory pathways, thus benefiting the development of auditory abilities and improving sound localization and the ability of auditory speech perception in situations of competitive noise.ObjectiveTo evaluate the ability of speech perception in children and adolescents using sequential bilateral cochlear implants, considering the association of these variables: age at surgery, time of device use and interval between surgeries.MethodsA total of 14 individuals between 10 and 16 years of age, who demonstrated surgical indication for the use of sequential bilateral cochlear implants as intervention in the auditory habilitation process, were assessed. The speech perception ability was assessed through sentence lists constructed in the Portuguese language, presented in two situations: in silence, with fixed intensity of 60 dB SPL, and in competitive noise, with a signal-to-noise ratio of +15 dB. The evaluation was performed under the following conditions: unilateral with the first activated cochlear implant, unilateral with the second activated cochlear implant and bilateral with both devices activated.ResultsThe results of the speech perception tests showed better performance in both silence and in noise for the bilateral cochlear implant condition when compared to the 1st cochlear implant and the 2nd cochlear implant alone. A worse result of speech perception was found using the 2nd cochlear implant alone. No statistically significant correlation was found between age at the surgical procedure, interval between surgeries and the time of use of the 2nd cochlear implant, and the auditory speech perception performance for all assessed conditions. The use of a hearing aid prior to the 2nd cochlear implant resulted in benefits for auditory speech perception with the 2nd cochlear implant, both in silence and in noise.ConclusionThe bilateral cochlear implant provided better speech perception in silence and in noise situations when compared to the unilateral cochlear implant, regardless of the interval between surgeries, age at the surgical procedure and the time of use of the 2nd cochlear implant. Speech perception with the 1st cochlear implant was significantly better than with the 2nd cochlear implant, both in silence and in noise. The use of the hearing aid prior to the 2nd cochlear implant influenced speech perception performance with the 2nd cochlear implant, both in silence and in noise.     

Endoscopic observation of different repair patterns in human traumatic tympanic membrane perforations

Introduction

In the last decade, there has been an increasing use of biomaterial patches in the regeneration of traumatic tympanic membrane perforations. The major advantages of biomaterial patches are to provisionally restore the physiological function of the middle ear, thereby immediately improving ear symptoms, and act as a scaffold for epithelium migration. However, whether there are additional biological effects on eardrum regeneration is unclear for biological material patching in the clinic.

Auditory and language skills of children using hearing aids

IntroductionHearing loss may impair the development of a child. The rehabilitation process for individuals with hearing loss depends on effective interventions.ObjectiveTo describe the linguistic profile and the hearing skills of children using hearing aids, to characterize the rehabilitation process and to analyze its association with the children's degree of hearing loss.MethodsCross-sectional study with a non-probabilistic sample of 110 children using hearing aids (6–10 years of age) for mild to profound hearing loss. Tests of language, speech perception, phonemic discrimination, and school performance were performed. The associations were verified by the following tests: chi-squared for linear trend and Kruskal–Wallis.ResultsAbout 65% of the children had altered vocabulary, whereas 89% and 94% had altered phonology and inferior school performance, respectively. The degree of hearing loss was associated with differences in the median age of diagnosis; the age at which the hearing aids were adapted and at which speech therapy was started; and the performance on auditory tests and the type of communication used.ConclusionThe diagnosis of hearing loss and the clinical interventions occurred late, contributing to impairments in auditory and language development.     

Retrospective analysis of skin complications related to bone-anchored hearing aid implant: association with surgical technique,quality of life,and audiological benefit

Introduction

The bone-anchored hearing aid is an effective form of auditory rehabilitation. Due to the nature of the implant, the most common complications are skin related. A number of alternative surgical implantation techniques have been used to reduce the frequency and severity of skin complications, including the U-shaped graft and the linear incision.

The role of red cell distribution width in the locoregional recurrence of laryngeal cancer

IntroductionAlthough the red cell distribution width has been reported as a reliable predictor of prognosis in several types of cancer, to our knowledge few reports have focused on the prognostic value of red cell distribution width in laryngeal carcinoma.ObjectiveWe aimed to explore whether the pretreatment red cell distribution width predicted recurrence in laryngeal cancer patients is a simple, reproducible, and inexpensive prognostic biomarker.MethodsAll laryngeal cancer patients who underwent curative surgery (n = 132) over a 7 year study period were evaluated. Data on demographics, primary tumor site, T-stage, N-stage, histological features (differentiation; the presence of perineural/perivascular invasion), treatment group (total laryngectomy or partial laryngectomy) or adjuvant therapy (chemotherapy/radiotherapy); laboratory parameters (complete blood count, including the pre-operative red cell distribution width), and disease-free survival rates were retrospectively reviewed. All cases were divided into three groups by the red cell distribution width tertile [<13% (25th percentile) (n = 31), 13–14.4% (50th percentile) (n = 72), and >14.4% (75th percentile) (n = 29)].ResultsHigh-red cell distribution width group included more patients of advanced age, and more of those with recurrent and metastatic tumors (p = 0.005, 0.048, and 0.043, respectively). Individuals with red cell distribution width >14.4% (75th percentile) had lower disease free survival rates than did those with red cell distribution width <13% (25th percentile) (p = 0.014). Patients with red cell distribution width >14.4% at diagnosis were at a higher risk of locoregional recurrence (hazard ratio = 5.818, 95% confidence interval (95% CI) 1.25–26.97; p = 0.024) than patients with a normal red cell distribution width (<13%).ConclusionWe found that the pretreatment red cell distribution width was independently prognostic of disease free survival rate in patients with laryngeal cancer and may serve as a new, accurate, and reproducible means of identifying early-stage laryngeal cancer patients with poorer prognoses.     

Preservation of residual hearing after cochlear implant surgery: an exploration of residual hearing function in a group of recipients at cochlear implant units

IntroductionThe preservation of residual hearing is becoming increasingly important in cochlear implant surgery. Conserving residual hearing is a positive prognostic indicator for improved hearing abilities.ObjectiveThe primary aim of the study was to explore the preservation of residual hearing following cochlear implantation in a group of recipients at two major cochlear implant centers.MethodsA quantitative paradigm was adopted and exploratory research conducted within a retrospective data review design. The sample consisted of 50 surgical records and 53 audiological records from 60 observations (53 patients, seven of whom were implanted bilaterally). The records were selected using purposive sampling and consisted of records from participants ranging from six to 59 years of age. The average time of when the postoperative audiograms were performed in the current study was 24.7 months (s.d. = ±9.0). Data were analyzed through both qualitative and inferential statistics and a comparative analysis of unaided pre- and postoperative audiological test results was conducted.ResultsResults indicated a high success rate of 92% preservation of residual hearing with half of the sample exhibiting complete preservation in cochlear implant recipients across all frequencies postoperatively. A total postoperative hearing loss was found in only 8% of cochlear implantees across all frequencies. There was no relationship between preoperative hearing thresholds and preservation of hearing postoperatively. The two main surgical techniques used in the current study were the contour on stylet and the advance off-stylet techniques, with the majority of surgeons utilizing a cochleostomy approach. From the findings, it became apparent that the majority of cases did not have any reported intraoperative complications. This is a positive prognostic indicator for the preservation of residual hearing.ConclusionFindings suggest improved cochlear implant surgical outcomes when compared to previous studies implying progress in surgical techniques. The surgical skill and experience of the surgeon are evidenced by the minimal intraoperative complications and the high success rate of hearing preservation. This is a positive prognostic indicator for individuals with preoperative residual hearing as the preserved residual hearing allows for the potential of electro-acoustic stimulation, which in turn has its own hearing benefits.     

Cross-cultural adaptation of the Amsterdam inventory for auditory disability and handicap to Brazilian Portuguese

IntroductionPatient-reported outcome measures, inventory and or questionnaire, allow patients to present their perspective of the impact of their individual condition on a day-to-day basis, independent of the analysis of test results by the expert clinician. Outcome measures are recommended when there is evidence showing their reliability, validity and sensitivity. There are standardized patient-reported outcome measures for hearing in English language; however, other languages lack these instruments.ObjectiveAdapt the Amsterdam inventory for auditory disability and handicap to Brazilian Portuguese and analyze its validation measures.MethodsWe conducted two studies. In Study 1, we translated and adapted the Amsterdam inventory for auditory disability and handicap to Brazilian Portuguese according to good practice guidelines; this included the pre-test stage. In Study 2, we administered the Portuguese version to adults with and without hearing loss (n = 31 and 18, respectively) and analyzed the measures of instrument validation, reliability, and reproducibility. Moreover, we calculated the correlation between pure tone thresholds and scores on the questionnaire.ResultsThe results obtained in Study 1 demonstrated the feasibility of the translation process and the instrument's cultural adaptation, as well as its applicability, resulting in the Portuguese version of the Amsterdam inventory for auditory disability and handicap. In Study 2, the results revealed construct values for the questions and domains, as well as for the total reliable score. The intra-interviewer test–retest condition showed excellent reproducibility (ICC = 0.97). Finally, there was a strong positive correlation (r = 0.83) between the mean pure tone threshold and the hearing difficulties values, as measured by the instrument's scores.ConclusionThe English version of the Amsterdam inventory for auditory disability and handicap could be translated and adapted to Brazilian Portuguese. An analyses of the validation process yielded reliable, consistent, and stable results.
