Risk factors for decreased distance between internal carotid artery and pharyngeal wall

Objectives

The risk of disastrous bleeding during pharyngeal surgery is increased in cases of an internal carotid artery (ICA) that is medially displaced due to its anomalous course. We attempted to assess the distance between the ICA and the pharyngeal wall (DIP) and to evaluate the predisposing factors associated with ICA variation.

Methods

The course of ICA was studied in 509 CT scans, and a retrospective chart review was performed. The course of ICA and DIP were evaluated at each level of the pharynx: nasopharynx (NP), oropharynx (OP), and hypopharynx (HP).

Results

The mean DIP value was greatest (15.8 ± 4.6 mm) at NP, decreased at OP (15.8 ± 4.6 mm), and was shortest at HP (13.5 ± 6.0 mm). DIP was significantly shorter in females compared with males at all three pharyngeal levels. Age was inversely correlated with DIP at NP and OP. Tortuous ICA was most common (51.4%), followed by straight (41.2%), kinking (6.9%), and coiling (0.5%) types. DIP was longest in the straight type and decreased as the curvature of ICA increased. The most common ICA type differed between younger (<60 years; 56.2% having the straight type) and older groups (≥60 years; 66.2% having the tortuous type). Females older than 60 years displayed a higher incidence of kinking ICA compared with males.

Conclusions

Hypopharynx, old age, female gender, and tortuous or kinking ICA types were risk factors for a decreased distance between the ICA and the pharyngeal wall. Meticulous examination of the pharyngeal wall should therefore be performed prior to pharyngeal surgery in patients with these associated risk factors.     

Cervical vascular and upper airway asymmetry in velo-cardio-facial syndrome: Correlation of nasopharyngoscopy with MRA

Purpose

Velo-cardio-facial syndrome (VCFS), the most common genetic syndrome causing cleft palate, is associated with internal carotid and vertebral artery anomalies, as well as upper airway asymmetry. Medially displaced internal carotid arteries, often immediately submucosal, present a risk of vascular injury during pharyngeal flap surgery for velopharyngeal insufficiency (VPI). We evaluate the frequency and spectrum of cervical vascular anomalies in a large cohort of VCFS patients correlating MRA with nasopharyngolaryngoscopy in detecting at risk carotid arteries. Furthermore, we assess the relationship with respect to laterality between cervical vascular patterns and the asymmetric abnormalities of these subjects’ upper airways.

Methods

Cervical MRAs of 86 subjects with VCFS and 50 control subjects were independently reviewed by three neuroradiologists. The course of the internal carotid and vertebral arteries was identified within the pharyngeal soft tissues. Medial deviation, level of bifurcation, dominance, anomalous origin, and vessel tortuosity were recorded. Nasopharyngoscopy examinations were available for retrospective review in 43 patients and were assessed for palatal and posterior pharyngeal wall symmetry, true vocal cord motion and size, and for the presence or absence of carotid pulsations. The endoscopic findings were compared with MRA results.

Results

Of the 86 subjects, 80 (93%) had one or more vascular anomalies. 42 subjects (49%) were found to have medial deviation of at least one internal carotid artery. In 24 subjects (28%) the anomalous internal carotid artery was directly submucosal; four of these were bilateral (5% of the total sample, 17% of those with a submucosal internal carotid). Other carotid anomalies included low carotid bifurcation (44 subjects or 51%), anomalous origin of the right common carotid (32 cases, or 37%), and two cases of internal carotid agenesis/hypoplasia. Vertebral artery anomalies included vessel tortuosity (34 cases, or 40%), hypoplasia (10 cases, or 12%), looping (4 cases, or 5%), and one case of a double left vertebral artery. Though patients in our study showed an asymmetric distribution of vascular anomalies, no association was found between the laterality of palatal motion, pharyngeal fullness, or laryngeal movement and structure with ipsilateral vertebral or carotid artery anomalies. Of the 33 pulsatile carotid arteries visualized at nasopharyngoscopy, only nine were found to be submucosal on MRA. In contrast, 11 submucosal carotid arteries confirmed at MRA demonstrated no visible pulsations. Positive and negative predictive values of pulsative arteries seen endoscopically for MRA confirmation of a submucosal carotid course was 27% and 79% respectively.

Conclusions

Carotid and vertebral artery anomalies are common in VCFS including marked medial deviation of the internal carotid artery in close proximity to the donor site for pharyngeal flap surgery. Lack of correlation between laterality of vascular anomalies and upper airway structural asymmetry in VCFS does not support the hypothesis that palatal, pharyngeal, and laryngeal anomalies are due to secondary developmental sequences caused by in utero vascular insufficiency. The presence or absence of carotid pulsations seen by nasopharyngoscopy does not correlate with the carotid arterial depth identified on MRA. Furthermore, identification of the relative medial-lateral retropharyngeal position of a submucosal carotid affords the opportunity to modify the surgical approach. These findings further support the routine use of pre-operative neck MRA in VCFS patients in surgical planning.     

The effect of rapid maxillary expansion on pharyngeal airway pressure during inspiration evaluated using computational fluid dynamics

Introduction

Recent evidence suggests that rapid maxillary expansion (RME) is an effective treatment of obstructive sleep apnea syndrome (OSAS) in children with maxillary constriction. Nonetheless, the effect of RME on pharyngeal airway pressure during inspiration is not clear. The purpose of this retrospective study was to evaluate changes induced by the RME in ventilation conditions using computational fluid dynamics.

Methods

Twenty-five subjects (14 boys, 11 girls; mean age 9.7 years) who required RME had cone-beam computed tomography (CBCT) images taken before and after the RME. The CBCT data were used to reconstruct 3-dimensional shapes of nasal and pharyngeal airways. Measurement of airflow pressure was simulated using computational fluid dynamics for calculating nasal resistance during exhalation. This value was used to assess maximal negative pressure in the pharyngeal airway during inspiration.

Results

Nasal resistance after RME, 0.137 Pa/(cm³/s), was significantly lower than that before RME, 0.496 Pa/(cm³/s), and the maximal negative pressure in the pharyngeal airway during inspiration was smaller after RME (−48.66 Pa) than before (−124.96 Pa).

Conclusion

Pharyngeal airway pressure during inspiration is decreased with the reduction of nasal resistance by the RME. This mechanism may contribute to the alleviation of OSAS in children.     

Transoral closure of pharyngeal perforation caused by gastrointestinal endoscopy

Objective

We present a case of pharyngeal perforation caused by gastrointestinal endoscopy that was successfully repaired with transoral mucosal sutures. This is the first report of a transoral surgical closure of a perforation caused by an endoscope. We describe the repair procedure, the necessary equipment, and the effectiveness of suturing pharyngeal perforations.

Patient

An 87-year-old woman brought to our emergency department by ambulance because of hematemesis and endoscopic hemostasis was successfully performed. But after hemostasis, CT scan showed emphysema extending from the right lower jaw to the superior mediastinum and pharyngeal perforation was observed by laryngeal fiberscope.

Intervention

Even though she had received conservative treatment, exacerbation of inflammation was observed and therefore we performed transoral surgery for closing the pharyngeal perforation.

Main outcome measure

We followed up with CT scans, blood test and vital signs.

Results

The pharyngeal perforation smoothly closed and exacerbation of inflammation was not observed, even after oral ingestion began.

Conclusion

Transoral closure of a pharyngeal perforation is less invasive and performing this procedure at an early stage can lead to a favorable outcome.     

Evaluation of cytologically benign solitary thyroid nodules by ultrasonography: A retrospective analysis of 1877 cases

Objective

The purpose of this study is to evaluate the role of ultrasonography (US) in the management of thyroid nodules when the cytology is benign tumor on fine needle aspiration biopsy (FNAB).

Methods

Between 2006 and 2011, we investigated 13,972 patients who had solitary thyroid nodule with cytological findings of benign. Surgery was performed according to our criteria for surgical indication. Of these patients, 1877 (13%) patients who underwent surgery were enrolled in this study. We compared the results of clinical findings including US classification and final histopathological diagnosis.

Results

One hundred seven (6%) after surgery were diagnosed as malignancy pathologically. Large nodule or high serum thyroglobulin level were not associated with an increased risk of malignancy. Ultrasonographic evaluation as malignancy was directly linked to pathological diagnosis as thyroid carcinoma (p < 0.001).

Conclusion

US may help to play a role in deciding whether surgical treatment is necessary for cytologically benign thyroid nodules.     

Sedation-related outcomes in postoperative management of pediatric laryngotracheal reconstruction

Objective

Examine outcomes of varied postoperative sedation management in pediatric patients recovering from single stage laryngotracheal reconstruction.

Design

Retrospective review of 34 patients treated with single stage laryngotracheal reconstruction from 2001 through 2011.

Setting

Tertiary children's hospital.

Methods

Patients were divided into 2 groups: those managed postoperatively with sedation, with or without paralysis (group 1), and those managed awake with narcotic pain medication as needed for primary management (group 2). Outcomes were measured as a function of sedation management. Outcomes investigated focused on those related to the success of the airway reconstruction, and those related to sedation management.

Results

Out of 68 cases of laryngotracheal reconstruction reviewed from 2001 to 2011, 34 were single stage reconstructions. Nineteen patients were sedated postoperatively (group 1) and fifteen patients were left awake (group 2). There were no significant differences between groups in airway-related outcomes, including risk of accidental decannulation, revision rates, and need for secondary airway procedures such as balloon dilation. Sedation-related outcomes, specifically focusing on differences in medical management, showed significant increases in rates of withdrawal (p < 0.0001), nursing concerns of withdrawal (p < 0.0001) and sedation level (p < 0.0001), pulmonary complications (OR 7.7, p = 0.008), and prolonged hospital stay due to withdrawal (p = 0.0005) in patients managed with sedation with or without paralysis. Multivariable regression analysis revealed that duration of sedation was the primary risk factor for increased postoperative morbidity, while younger age, lower weight, and use of a posterior graft were also significant variables assessed.

Conclusion

Avoiding sedation as the standard for postoperative management of single stage laryngotracheal reconstruction airway patients leads to an overall decreased risk of morbidity without increasing risk of airway-specific morbidity. This is specifically as related to withdrawal, pulmonary complications, concerns about sedation level and prolonged hospital course, all of which increase significantly with increased level and duration of sedation.     

Evaluation of swallowing pressure in a patient with amyotrophic lateral sclerosis before and after cricopharyngeal myotomy using high-resolution manometry system

Background

This study aimed to evaluate the pharyngeal pressure of a patient with, amyotrophic lateral sclerosis (ALS) before and after cricopharyngeal myotomy by high-resolution manometry (HRM) system.

Methods

A 60-year-old man with ALS underwent cricopharyngeal myotomy for his intractable, aspiration. The swallowing pressure along the velopharynx and upper esophagus was measured using, the HRM 1 month before and 3 months after the surgery.

Results

Before cricopharyngeal myotomy, the maximum values of the resting UES pressure, the dry swallowing, pressures in the velopharyngeal muscle zone and in the UES zone were 89, 95, and 171 mmHg, respectively. After surgery, the maximum values of both the resting pressure and dry swallowing, pressure in the UES zone remarkably decreased to 21 and 75 mmHg, respectively.

Conclusions

This is the first report showing the effect of cricopharyngeal myotomy by demonstrating, the difference in the swallowing pressure along the velopharynx and upper esophagus before and after, the surgery in an ALS patient using this HRM system.     

Clinical evaluation of pepsin for laryngopharyngeal reflux in children with otitis media with effusion

Objective

We sought to evaluate the clinical role of pepsin for laryngopharyngeal reflux (LPR) in children with otitis media with effusion (OME).

Methods

Pepsin/pepsinogen and fibrinogen were analyzed in fifty effusion and blood samples of children with OME using enzyme linked immunosorbent assay (ELISA). Ambulatory 24-h dual-probe pH monitoring was additionally performed in 31 children divided into two groups according to response of medical treatment.

Results

The effusion levels of pepsin/pepsinogen ranged from 8.5 to 1512 μg/dl and were up to 4–540 times higher than the concentrations found in plasma samples. The effusion levels of fibrinogen ranged from 0.05 to 4.1 g/dl. Some effusion samples showed fibrinogen concentrations did not exceed 10 times higher than the concentrations found in plasma samples and others showed lower concentrations. The pH of effusion samples was 7.13 to 8.72. Dual-probe pH monitoring showed that 22/31 (71%) of the studied children had significant acid reflux documented by either the esophageal probe or the pharyngeal probe and all of them had LPR. There is a significant positive correlation between the level of pepsin assayed in the effusions and the number of pharyngeal reflux episodes measured by pH monitoring.

Conclusions

Analysis of pepsin/pepsinogen in effusion samples of children with OME, using ELISA, can be considered as a reliable biochemical marker for assessment of laryngopharyngeal reflux.     

Analysis of obstruction site in obstructive sleep apnea syndrome patients by drug induced sleep endoscopy

Purpose

We analyzed site, pattern and degree of obstruction in Korean male obstructive sleep apnea syndrome (OSAS) patients by drug-induced sleep endoscopy (DISE). We also investigated possible links between BMI, AHI and DISE findings.

Materials and methods

Sixty-nine male patients underwent DISE. DISE findings were reported using our classification system in which modified ‘VOTE classification’ – obstruction type, site of obstruction, degree of obstruction and anatomical site contributing obstruction – was reported. Associations were analyzed among the results of the polysomnography, patients' characteristics and DISE finding.

Results

Multilevel airway obstruction was found in 84.06% of patients and 15.94% had a unilevel obstruction. Among those with unilevel obstruction, 90.90% had retropalatal level obstruction and 9.10% had retrolingual level obstruction. Palate with lateral pharyngeal wall obstruction (49.28%) is the most common obstruction type of the retropalatal level and tongue with lateral pharyngeal wall (37.68%) is the most common obstruction type of the retrolingual level. Examining the relation between obstruction site according to body mass index (BMI) and severity of OSAS (apnea hypopnea index, AHI), the lateral pharyngeal wall had an increasing tendency associated with higher BMI and higher AHI. But the lateral pharyngeal wall of both levels was statistically significant associated with higher AHI.

Conclusion

The majority of the Korean male OSAS patients have multilevel obstruction and according to BMI and AHI, the DISE findings indicate that the lateral pharyngeal wall is the most important anatomical site contributing to obstruction regardless of the level at which the obstruction lies.     

Recurrence pattern after conservative surgery for papillary thyroid carcinoma

Objective

Risk-based treatment represents the optimal management strategy for papillary thyroid carcinoma; however, the optimal extent of thyroidectomy and neck dissection remains controversial. This study aims to clarify the pattern of recurrence after conservative surgery in patients with papillary thyroid carcinoma.

Methods

We retrospectively reviewed 93 patients with papillary thyroid carcinoma treated with conservative surgery. We analyzed recurrence rate, recurrence pattern, risk factors for recurrence, salvage treatment, and disease-free survival (DFS) in patients stratified according to risk.

Results

The recurrence rate was significantly lower in the low-risk group compared with the high-risk group (14% vs 34%; p < 0.01). The recurrence pattern also differed between the two groups, with ipsilateral lateral neck recurrence being more common in the low-risk group (9%), while contralateral lateral neck recurrence was more common in the high-risk group (18%). Patients with contralateral thyroid lobe metastasis and/or direct contralateral thyroid lobe invasion showed a significantly higher rate of contralateral lateral neck metastasis than patients negative for both these features. The overall 5-year DFS was 81% in all patients. Advanced T and N classification, large primary tumor (≥4 cm), extrathyroidal invasion, and high-risk group were significantly associated with poorer 5-year DFS in univariate analysis.

Conclusion

Conservative surgery may represent a good treatment option for patients with low-risk papillary thyroid carcinoma. Tumor recurrence patterns differ between risk groups, with contralateral thyroid lobe lesions and direct contralateral lobe invasion being risk factors for contralateral lateral neck recurrence.     

A prospective CBCT study of upper airway changes after rapid maxillary expansion

Objective

The aim of this prospective study was to investigate the upper airway changes after rapid maxillary expansion utilizing CBCT.

Methods

16 children (10 male, 6 female) with a mean age of 12.73 ± 1.73 years underwent RME as part of their comprehensive orthodontic treatment with4,6-banded hyrax expanders. The screws were activated 2 turns a day. Depending on the expansion amount (2.7–6.3 mm), the activation period ranged from 2 to 3 weeks. CBCT images were taken immediately before (T1) and three months after expansion (T2) in upright position, with patients’ heads kept in consistent position. All CBCT data were processed with the software EZ3D2009. After orienting the CBCT images, a set of linear, area and volumetric parameters of the upper airway were measured and calculated. Student paired t test and one-way ANOVA were applied. The significance level of P < 0.0033 was used according to the Bonferroni correction.

Results

After expansion, with molar-to-molar width increasing 4.4 ± 1.3 mm and molars tipping 6.2 ± 6.2°, the nasal floor width and nasal lateral width increased 1.6, 1.5, and 1.6 mm and 1.3, 1.7, and 1.4 mm from the anterior to the posterior part, respectively. And there was no difference among the anterior, median and posterior part. The lower nasal volume increased 1348.5 mm³ with the percentage change being 8.1%. The pharyngeal airway showed no positive change.

Conclusion

RME can expand the nasal cavity and the expansion pattern may follow the parallel opening configuration. However, the influence on the pharyngeal airway is limited.     

Effect of cold-water cooling of tonsillar fossa and pharyngeal mucosa on post-tonsillectomy pain

Purpose

Post-tonsillectomy pain is a notable concern and thermal injury produced by electric surgical devices is considered a main cause. Intraoperative cooling of the tonsillar fossa and pharyngeal mucosa with cold water has effectively reduced postoperative pain, but no studies have fully evaluated the effects of this technique with a proper study design. We assessed mucosal cooling in two groups of patients undergoing the same surgical technique by a single surgeon, with one group receiving cold-water cooling and the other group as a control.

Methods

Forty patients who underwent monopolar electrocautery tonsillectomy were randomly assigned to two groups (n = 20 for each group). Group 1 received cooling of the tonsillar fossa and pharyngeal mucosa with 4 °C saline just after removal of each tonsil whereas Group 2 did not receive cooling. Postoperative pain was recorded on operation day and 1, 2, 4, 7, and 10 days postoperatively. Post-tonsillectomy pain, return to normal diet, and incidence of postoperative bleeding were compared between the groups.

Results

Post-tonsillectomy pain on 6 selected days and overall pain during the 10-day follow-up period were significantly lower in Group 1. However, return to normal diet and incidence of postoperative bleeding did not differ significantly between the groups.

Conclusions

Intraoperative application of cold water after tonsillectomy significantly reduced postoperative pain. We recommend cooling the tonsillar fossa and pharyngeal mucosa with cold water during tonsillectomy to easily and effectively reduce post-tonsillectomy pain.     

Functional outcome after partial glossectomy with reconstruction using radial forearm free flap

Objective

The purpose of this study was to investigate the relationship between the radial forearm free flap (RFFF) volume changes and speech and swallowing outcomes.

Methods

The study included 18 subjects with squamous cell carcinoma of the oral tongue.

Results

Average percentage changes in flap volume between 3 and 12 months was 19.2%. Postoperative free flap volume changes were significantly and negatively correlated with the word and sentence intelligibility (Y = −0.338X + 43.641, r² = 0.383, p = 0.006 and Y = −0.246X + 34.322, r² = 0.321, p = 0.014, respectively). A significant positive correlation was also found between word and sentence intelligibility and floor of mouth resected, postoperative irradiation. Postoperative flap volume changes between 3 and 12 months were correlated with reduced posterior bolus movement by tongue (p = 0.002), reduced tongue base to posterior pharyngeal wall contact (p = 0.002), reduced laryngeal elevation (p = 0.005), increased aspiration (p = 0.005), delayed oral (p = 0.010) and pharyngeal transit time (p = 0.011). Floor of mouth resected, tongue base resected, and postoperative irradiation also influenced the swallowing outcomes.

Conclusions

This study shows that postoperative flap volume changes are significantly related to speech and swallowing outcomes in patients undergoing partial glossectomy reconstructed with RFFF.     

Clinical significance of upper airway obstruction pattern during apneic episodes on ultrafast dynamic magnetic resonance imaging

Objectives

In order to assess the relationship between upper airway obstruction pattern and the clinical characteristics of obstructive sleep apnea syndrome (OSAS), we evaluated dynamic changes in the pharyngeal airway of patients with the disorder by using ultrafast dynamic magnetic resonance imaging (MRI).

Methods

MRI while asleep was performed on 31 patients with OSAS (29 men, 2 women; mean age, 46.6 ± 8.2 years; mean body mass index, 26.7 ± 4.9 kg/m²; mean AHI, 40.6 ± 21.7 episodes/h). Relationships between obstruction pattern focusing on differences between single-site obstruction (SO) and multiple-site obstructions (MO) and titrated value of nasal CPAP in addition to respiratory variables were investigated.

Results

The velopharynx (VP) was the main obstructive site among most of the cases with SO (17 of 18 cases), and all of the cases with MO (n = 13) showed obstruction at and below the VP. AHI was significantly higher in cases with MO than in those with SO (P < 0.01). As for SaO₂ variables, minimum value during sleep was significantly lower and total time with SaO₂ £90% was longer in cases with MO than in those with SO (P < 0.05 each). Titrated value of n-CPAP was also significantly higher in cases with MO than in cases with SO (P < 0.05).

Conclusions

Our results strongly suggest that formation of MO manifested on ultrafast dynamic MRI could be related to increased severity of the disorder. Considering the higher titrable value of CPAP, MO could be brought about by high pharyngeal pressure.     

Frequency of acne vulgaris and its exacerbation in facial and periorbital area after septorhinoplasty

Background

High prevalence of rhinoplasty, controversies about its cutaneous complications and lack of structured studies about relationship between acne vulgaris and rhinoplasty, point out the necessity for performing this study.

Purpose

To determine the frequency of acne and its exacerbation after rhinoplasty.

Materials and methods

In a longitudinal controlled study at a tertiary referral university hospital, the degree of acne before and 1 and 3 months after surgery was measured in 110 patients (30 Male, 80 Female, Mean age: 26.3 ± 6.8) with rhinoplasty and 80 patients (35 Male, 45 Female, Mean age: 24.5 ± 4.6) with septoplasty, based on Global Acne Grading System (GAGS). The data were analyzed by SPSS 16 software.

Results

The frequency of acne exacerbation in first post-surgical visit was 27% in case and 3.5% in control subjects (P < 0.007). In case group, 42.9% of those who had no acne before surgery, developed mild acne and 14.5% of those with mild acne, turned into moderate acne. In second post-surgical visit 91.7% of those who had moderate acne in first visit, turned into mild acne and 80% of those with severe acne in first post-surgical visit changed into moderate acne without any specific therapy (P < 0.0001 and P < 0.001, respectively).

Conclusions

Rhinoplasty has significant relationship with acne exacerbation. The severity of acne decreases gradually during 3 months after surgery. For determining the exact course and risk factors of this complication, further studies are needed.     

Second branchial cyst in the parapharyngealspace: a case report

Objective

We report the clinical findings and management of a large retro- and parapharyngeal branchial cyst in a 54-year-old man whose only complaint was a 12-month history of snoring.

Method

Case report and a review of the world literature concerning parapharyngeal cysts are presented.

Results

On computed tomography (CT) images, a well-marginated cystic mass was observed in the left retro- and parapharyngeal spaces, with displacement of the left internal and common carotid arteries. The cyst contained thick, sterile, yellowish pus, without malignant cells. We performed a transoral resection without any surgical complications. No recurrence was observed 2 years later.

Conclusion

Parapharyngeal branchial cysts are rare and often paucisymptomatic. The transoral approach can provide good exposure allowing complete resection without significant post-operative complications or cervical scarring.     

Repeat PEG placement is safe for head and neck cancer patients

Purpose

Percutaneous endoscopic gastrostomy (PEG) provides durable nutritional access for head and neck (HNC) patients as they undergo treatment. Continuing treatment of HNC may necessitate repeat PEG placement. We report our outcomes with repeat PEG compared to first-time PEG in HNC patients.

Materials and Methods

A retrospective chart review identified morbidity, mortality, and possible risk factors for complications.

Results

Repeat PEG tubes constituted 17% of PEG procedures. Morbidity was rare and similar complication rates were found between the initial PEG and repeat PEG groups (2% vs. 11%, p = 0.131). There were no mortalities.

Conclusions

Repeat PEG plays an important role in the care of HNC patients and can be considered a safe means to establish durable enteric feeding access for patients with recurrent cancer or treatment complications.     

Gastroesophageal reflux as a predictor of complications after adenotonsillectomy in young children

Objective

To examine characteristics of young children with gastroesophageal reflux (GER) who experienced complications within the first 24 h after adenotonsillectomy.

Study design

Subset analysis of a larger retrospective cohort.

Methods

A retrospective chart review was performed at a tertiary care children's hospital. Consecutive records of children 3 years old and younger undergoing adenotonsillectomy (AT) over a 5-year period were reviewed. Children with a clinical history of GER were selected for the study.

Results

993 children were included in the initial analysis, and GER was found to be a significant independent variable predictive of early complications. 81 children with a history of GER were included in this study and 8 (9.9%) were found to have experienced complications within the first 24 h. Six of the complications were airway-related; two required re-intubation within the first 24 h. All 8 children with complications had symptoms of sleep-disordered breathing and two had documented severe obstructive sleep apnea (AHI 18.6 and 27.2). Seven children had other risk factors for complications after AT. Eighteen (22%) children had a prolonged length of stay (range 2–7 days); additional risk factors were present in these patients as well.

Conclusions

Knowledge of risk factors for complications following adenotonsillectomy is critical for identifying at-risk patients that may warrant closer post-operative observation. GER has been previously identified as a risk factor for complications in young children. Upon closer analysis, young children with GER who have other known risk factors may be at a further increased risk for airway complications and prolonged hospitalization. Parents of these children can be counseled on the post-operative risks and the possibility of a longer hospitalization.     

Oral squamous cell carcinoma in post-transplant patients

Objective

Patients on immunosuppressant therapy after transplantation have an increased risk of developing cutaneous squamous cell carcinomas. The risk of developing solid tumors of the upper aerodigestive tract in this population has been less defined. We present five patients that subsequently developed oral squamous cell carcinoma after transplantation.

Study design

Retrospective chart review and literature review.

Results

Three bone marrow and two heart transplant patients were subsequently diagnosed with oral (oral cavity or oropharynx) carcinoma. The timing of diagnosis of oral cancer after transplant ranged from 18 months to 17 years post-transplantation.

Conclusions

Patients with a history of transplantation should be routinely assessed for the potential development of oral neoplastic lesions. Oral squamous cell carcinoma in transplant patients can be more aggressive and clinically mistaken for chronic graft versus host disease. It is therefore reasonable to consider early biopsy in these patients to guide the need for intervention.
