RESUMO
OBJECTIVE: To examine the prevalence of hearing impairment in children with hypothyroidism, and to characterize clinical and subclinical hearing loss by examining cochlear function, auditory brainstem pathways, and integration of the auditory system as a whole. DESIGN: An electronic search was conducted using PubMed, Scopus, and Cochrane Library databases. This systematic review was performed in accordance with the PRISMA guidelines. Original observational studies that utilized audiological tests for auditory system evaluations in hypothyroidism were included. A total of 2004 studies were found in the search, with 23 studies meeting the inclusion criteria. RESULTS: The pooled prevalence of hearing loss was 16.1% [95% confidence interval 10.7, 22.4] for children with congenital hypothyroidism. Hearing thresholds at pure-tone averages (0.5-2 kHz) were 1.6 dB [95% confidence interval 1.7, 4.8] higher for children with hypothyroidism compared to age-matched controls. Cochlear dysfunction was detected at middle frequencies (1-3 kHz) by otoacoustic emission testing, indicating abnormalities of hair cell function or cochlear integration. Retrocochlear involvement was detected on auditory brainstem response (ABR), with prolonged Wave I indicating a peripheral conduction abnormality localized to the middle or inner ear and eighth cranial nerve. CONCLUSIONS: Children with hypothyroidism have a higher prevalence of hearing loss than children without hypothyroidism. For children with congenital hypothyroidism, evidence of subclinical abnormalities at the level of the cochlea and eighth cranial nerve are present despite early initiation of levothyroxine therapy. Dysfunction of the auditory system might begin with predominance of peripheral conduction abnormalities early in development.

The authors sought to compare hospital utilization and complications in patients undergoing pharyngeal flap (PF) or sphincter pharyngoplasty (SP) for velopharyngeal insufficiency (VPI). A retrospective analysis of the 2014 and 2015 American College of Surgeons National Surgical Quality Improvement Project-Pediatrics (ACS NSQIP-P) was performed. Current procedural terminology codes were used to identify children undergoing PF (42225, 42226) and SP (42950) for VPI (International Classification of Diseases version 9: 478.29, 528.9, or 750.29). Four hundred forty-six patients were treated for VPI with either PF (nâ=â250) or SP (nâ=â196). The groups were demographically similar in age, gender, race, and preoperative comorbidity. Pharyngeal flap was performed less often as an outpatient procedure than SP (96/250 [38.4%] vs 130/196 [66.3%], Pâ<â0.0001) and had a longer total length of hospital stay (mean 1.76â±â1.29 vs 0.98â±â0.91 days, Pâ<â0.0001). No difference in total complications (10/250 [4.0%] vs 3/196 [1.5%], Pâ=â0.124) was identified. The reduction in hospital resource utilization (fewer admissions, shorter length of stay) is notable. No difference in complications was identified between the 2 procedures.

Metaheuristics are an effective and diverse class of optimization algorithms: a means of obtaining solutions of acceptable quality for otherwise intractable problems. The selection, construction, and configuration of a metaheuristic for a given problem has historically been a manually intensive process based on experience, experimentation, and reasoning by metaphor. More recently, there has been interest in automating the process of algorithm configuration. In this article, we identify shared state as an inhibitor of progress for such automation. To solve this problem, we introduce the Automated Open-Closed Principle (AOCP), which stipulates design requirements for unintrusive reuse of algorithm frameworks and automated assembly of algorithms from an extensible palette of components. We demonstrate how the AOCP enables a greater degree of automation than previously possible via an example implementation.

Therapeutic botulinum toxin injections are commonly performed in pediatric otolaryngology. Aerodigestive complications from botulinum toxin injections, although rare, may be serious. Oral pyridostigmine is effective in the symptomatic treatment of these complications. We report 2 cases of aerodigestive complications arising from injection of botulinum toxin that were successfully treated with pyridostigmine.

BACKGROUND: The role of calcium hydroxylapatite injection pharyngoplasty after failed sphincter pharyngoplasty surgery has not previously been described. We report our technique of injecting calcium hydroxylapatite into the pharyngoplasty site to add bulk to specific areas of the velopharyngeal port. METHODS: A retrospective review of children undergoing calcium hydroxylapatite injection pharyngoplasty for persistent velopharyngeal insufficiency after sphincter pharyngoplasty was performed. Our surgical technique is described. Outcome measures included postoperative perceptual assessment of resonance, improvement in phoneme-specific nasometry scores, and rate of revision surgery. RESULTS: Fourteen patients were included in the study. Improvement in hypernasality on perceptual assessment was noted in the majority of children (85.7%). The rate of achievement of normal resonance on perceptual analysis was 35.7%. A significant decrease in nasometry scores was noted for the following phonemes: /pa/, /sa/, /sha/, and /pi/. There were no intraoperative complications or immediate postoperative complications associated with calcium hydroxylapatite injection. CONCLUSIONS: Our early experience suggests that calcium hydroxylapatite injection after failed sphincter pharyngoplasty is a safe, minimally invasive technique with favorable short-term results.

OBJECTIVE: To analyze the rates of complications after pediatric temporal bone fractures (TBF) and the utility of the longitudinal, transverse, and mixed versus the otic capsule sparing (OCS) and otic capsule violating (OCV) classification systems in predicting these complications. DATA SOURCES: PubMed, Scopus, and CINAHL. REVIEW METHODS: Per PRISMA guidelines, studies of children with TBFs were included. Meta-analyses of proportions were performed. RESULTS: A total of 22 studies with 1376 TBFs were included. Children with TBF had higher rates of conductive hearing loss (CHL) than sensorineural hearing loss (SNHL) (31.3% [95% confidence interval [CI] 23.2-40.1] vs 12.9% [95% CI 8.9-17.5]). No differences in both CHL and SNHL were seen between longitudinal and transverse TBFs; however, OCV TBFs had higher rates of SNHL than OCS TBFs (59.3% [95% CI 27.8-87.0] vs 4.9% [95% CI 1.5-10.1]). Of all patients, 9.9% [95% CI 7.2-13.1] experienced facial nerve (FN) paresis/paralysis, and 13.4% [95% CI 5.9-23.2] experienced cerebrospinal fluid otorrhea. Transverse TBFs had higher rates of FN paresis/paralysis than longitudinal (27.7% [95% CI 17.4-40.0] vs 8.6% [95% CI 5.2-12.8]), but rates were similar between OCS and OCV TBFs. CONCLUSION: CHL was the most common complication after TBF in children; however, neither classification system was superior in identifying CHL. The traditional system was more effective at identifying FN injuries, and the new system was more robust at identifying SNHL. While these results suggest that both classification systems might have utility in evaluating pediatric TBFs, these analyses were limited by sample size. Future research on outcomes of pediatric TBFs stratified by type of fracture, mainly focusing on long-term outcomes, is needed.

OBJECTIVES: To analyze characteristics of children treated for laryngomalacia to determine predictive factors and provide an updated meta-analysis on outcomes. METHODS: A systematic review was conducted according to PRISMA guidelines from inception to May 2, 2023, using CINAHL, PubMed, and Scopus databases. Study screening, data extraction, quality rating, and risk of bias assessment were performed by 2 independent reviewers. Data were meta-analyzed using fixed-/random-effects model to derive continuous measures (mean), proportions (%), and mean difference (Δ) with 95% confidence interval (CI). RESULTS: 100 articles were identified with information on outcomes of pediatric patients with laryngomalacia (N = 18,317). The mean age was 10.6 months (range: 0 to 252, 95%CI: 9.6 to 11.6, p = 0.00) with a 1.4:1 male to female ratio. Many patients presented with stridor (87.9%, 95% CI: 69.8 to 98.4), and the most common comorbidity at time of diagnosis was gastroesophageal reflux disease (48.8%, 95%CI: 40.9 to 56.8). Based on the patient population included in our analysis, 86.1% received supraglottoplasty (95% CI: 78.7 to 92.1). A total of 73.6% (95% CI: 65.5 to 81.0) had reported complete resolution of symptoms. For patients with a concurrent diagnosis of sleep disordered breathing receiving supraglottoplasty, the apnea-hypopnea index improved with a mean difference of -10.0 (95%CI: 15.6 to -4.5) events per hour post-treatment. CONCLUSIONS: Laryngomalacia continues to be a common problem in the pediatric population. Supraglottoplasty remains an effective treatment option leading to symptomatic improvement in many cases. For those with concurrent sleep disordered breathing, supraglottoplasty lowers the apnea-hypopnea index.

OBJECTIVE: To review the literature on pneumococcal vaccination compliance rates among cochlear implant (CI) patients and to examine the utility of intervention programs on increasing vaccination rates. DATA SOURCES: PubMed, Scopus, and CINAHL. REVIEW METHODS: A systematic review was performed following PRISMA guidelines. Studies of pneumococcal vaccination rates at baseline and before and after the implementation of a quality improvement (QI) intervention were included. A total of 641 studies were screened, and 13 studies met inclusion criteria. Meta-analyses of pneumococcal vaccination rates pre- and post-QI intervention in CI patients were performed. RESULTS: A total of 12,973 children and adults were included. The baseline PCV13 and PPSV23 vaccination rates were 53.45% (95% CI, 37.02%-69.51%) and 42.53% (95% CI, 31.94%-53.48%), respectively. Comparing children and adults, PCV13 and PPSV23 baseline vaccination rates were not statistically significant. The PPSV23 vaccine rate after QI initiatives was significantly higher than the baseline rate at 83.52% (95% CI, 57.36%-98.46%). After these interventions, patients had a 15.71 (95% CI, 4.32-57.20, P < .001) increased odds of receiving PPSV23 vaccination compared to before QI implementation. CONCLUSIONS: The baseline rates of PCV13 and PPSV23 are highly variable and lower than expected, given current vaccination recommendations for CI patients. QI programs appear successful in increasing compliance rates with the PPSV23 vaccination; however, they are still far from full compliance. Further intervention programs with stricter surveillance, monitoring, and follow-up systems are needed to achieve improved compliance with the PCV13 and PPSV23 vaccination in CI recipients.

Fibromyalgia (FM) is characterized by chronic widespread musculoskeletal pain and psychological distress. Research suggests people with FM experience increased somatosensory sensitization which generalizes to other sensory modalities and may indicate neural hyperexcitability. However, the available evidence is limited, and studies including measures of neural responsivity across sensory domains and both central and peripheral aspects of the neuraxis are lacking. Thirty-nine participants (51.5 ± 13.6 years of age) with no history of neurological disorders, psychosis, visual, auditory, or learning deficits, were recruited for this study. People with FM (N = 19) and control participants (CNT, N = 20) did not differ on demographic variables and cognitive capacity. Participants completed a task that combined innocuous auditory stimuli with electrocutaneous stimulation (ECS), delivered at individually-selected levels that were uncomfortable but not painful. Event-related potentials (ERPs) and electrodermal activity were analyzed to examine the central and sympathetic indices of neural responsivity. FM participants reported greater sensitivity to ECS and auditory stimulation, as well as higher levels of depression, anxiety, ADHD, and an array of pain-related experiences than CNT. In response to ECS, the P50 deflection was greater in FM than CNT participants, reflecting early somatosensory hyperexcitability. The P50 amplitude was positively correlated with the FM profile factor obtained with a principal component analysis. The N100 to innocuous tones and sympathetic reactivity to ECS were greater in FM participants, except in the subgroup treated with gabapentinoids, which aligns with previous evidence of symptomatic improvement with GABA-mimetic medications. These results support the principal tenet of generalized neural hyperexcitability in FM and provide preliminary mechanistic insight into the impact of GABA-mimetic pharmacological therapy on ameliorating the neural excitation dominance.
RESUMO
OBJECTIVE: To investigate the impact of the surgical indication on posttonsillectomy bleed rates. DATA SOURCES: PubMed, Scopus, CINAHL. REVIEW METHODS: A systematic review was performed searching for articles published from the date of inception to July 6, 2022. English language articles describing posttonsillectomy hemorrhage rates in pediatric patients (age ≤ 18) stratified by indication were selected for inclusion. A meta-analysis of proportions with comparison (Δ) of weighted proportions was conducted. All studies were assessed for risk of bias. RESULTS: A total of 72 articles with 173,970 patients were selected for inclusion. The most common indications were chronic/recurrent tonsillitis (CT/RT), obstructive sleep apnea/sleep-disordered breathing (OSA/SDB), and adenotonsillar hypertrophy (ATH). Posttonsillectomy hemorrhage rates for CT/RT, OSA/SDB, and ATH were 3.57%, 3.69%, and 2.72%, respectively. Patients operated on for a combination of CT/RT and OSA/SDB had a bleed rate of 5.99% which was significantly higher than those operated on for CT/RT alone (Δ2.42%, p = .0006), OSA/SDB alone (Δ2.30%, p = .0016), and ATH alone (Δ3.27%, p < .0001). Additionally, those operated on for a combination of ATH and CT/RT had a hemorrhage rate of 6.93%, significantly higher than those operated on for CT/RT alone (Δ3.36%, p = .0003), OSA/SDB alone (Δ3.01%, p = .0014), and ATH alone (Δ3.98%, p < .0001). CONCLUSION: Patients operated on for multiple indications had significantly higher rates of posttonsillectomy hemorrhage than those operated on for a single surgical indication. Better documentation of patients with multiple indications would help further characterize the magnitude of the compounding effect described here.

After recovering from the acute COVID-19 illness, a substantial proportion of people continue experiencing post-acute sequelae of COVID-19 (PASC), also termed "long COVID". Their quality of life is adversely impacted by persistent cognitive dysfunction and affective distress, but the underlying neural mechanisms are poorly understood. The present study recruited a group of mostly young, previously healthy adults (24.4 ± 5.2 years of age) who experienced PASC for almost 6 months following a mild acute COVID-19 illness. Confirming prior evidence, they reported noticeable memory and attention deficits, brain fog, depression/anxiety, fatigue, and other symptoms potentially suggestive of excitation/inhibition imbalance. Proton magnetic resonance spectroscopy (1H-MRS) was used to examine the neurochemical aspects of cell signaling with an emphasis on GABA levels in the occipital cortex. The PASC participants were compared to a control (CNT) group matched in demographics, intelligence, and an array of other variables. Controlling for tissue composition, biological sex, and alcohol intake, the PASC group had lower GABA+/water than CNT, which correlated with depression and poor sleep quality. The mediation analysis revealed that the impact of PASC on depression was partly mediated by lower GABA+/water, indicative of cortical hyperexcitability as an underlying mechanism. In addition, N-acetylaspartate (NAA) tended to be lower in the PASC group, possibly suggesting compromised neuronal integrity. Persistent neuroinflammation may contribute to the pathogenesis of PASC-related neurocognitive dysfunction.
RESUMO
OBJECTIVE(S): To analyze the utility of computed tomography angiography (CTA) in identifying internal carotid artery (ICA) injury and reducing cerebrovascular accident (CVA) incidence in children presenting with normal neurologic exams after oropharyngeal trauma (OT). DATA SOURCES: PubMed, Scopus, CINAHL, and Cochrane. REVIEW METHODS: A systematic review and meta-analysis were performed following PRISMA guidelines. Of 1,185 studies screened, 95 studies of pediatric OT met inclusion criteria. Meta-analysis of proportions was performed. RESULTS: A total of 1224 children with OT were analyzed. Excluding case reports, the weighted proportion of a CVA after OT was 0.31% (95% CI 0.06-0.93). If a child presented without neurologic deficits, 0.30% (95% CI 0.05-0.95) returned with new neurologic deficits. An ICA injury was identified in 0.89% (95% CI 0.16-2.74) of screening CTAs. No difference in CVA incidence was seen in children with screening CTA (0.52% [95% CI 0.02-2.15]) compared to children without screening CTA (0.42% [95% CI 0.06-1.37]). Patients who developed CVA had a higher proportion of injuries >2 cm, injuries at the posterior pillar or tonsil, and injuries with a writing utensil or popsicle stick compared to patients without CVA. CONCLUSION: The proportion of children experiencing an ICA injury leading to CVA after sustaining OT is low. CTAs infrequently show ICA changes in children with normal neurological exams. Children who receive CTAs do not have a significantly lower incidence of CVAs than children who do not receive CTAs. Clinicians should weigh the risks and benefits of a CTA based on an individual child's presentation and discuss this with caregivers for shared decision-making. Laryngoscope, 133:25-37, 2023.

Individuals with autism spectrum disorders (ASD) vary in their language abilities, associated with atypical patterns of brain activity. However, few studies have examined the spatiotemporal profiles of lexico-semantic processing in ASD, particularly as a function of language heterogeneity. Thirty-nine high-functioning adolescents with ASD and 21 typically developing (TD) peers took part in a lexical decision task that combined semantic access with demands on cognitive control. Spatiotemporal characteristics of the processing stages were examined with a multimodal anatomically-constrained magnetoencephalography (aMEG) approach, which integrates MEG with structural MRI. Additional EEG data were acquired from a limited montage simultaneously with MEG. TD adolescents showed the canonical left-dominant activity in frontotemporal regions during both early (N250m) and late (N400m) stages of lexical access and semantic integration. In contrast, the ASD participants showed bilateral engagement of the frontotemporal language network, indicative of compensatory recruitment of the right hemisphere. The left temporal N400m was prominent in both groups, confirming preserved attempts to access meaning. In contrast, the left prefrontal N400m was reduced in ASD participants, consistent with impaired semantic/contextual integration and inhibitory control. To further investigate the impact of language proficiency, the ASD sample was stratified into high- and low-performing (H-ASD and L-ASD) subgroups based on their task accuracy. The H-ASD subgroup performed on par with the TD group and showed greater activity in the right prefrontal and bilateral temporal cortices relative to the L-ASD subgroup, suggesting compensatory engagement. The L-ASD subgroup additionally showed reduced and delayed left prefrontal N400m, consistent with more profound semantic and executive impairments in this subgroup. These distinct spatiotemporal activity profiles reveal the neural underpinnings of the ASD-specific access to meaning and provide insight into the phenotypic heterogeneity of language in ASD, which may be a result of different neurodevelopmental trajectories and adoption of compensatory strategies.

OBJECTIVES: To perform a systematic review of otolaryngologic presentation rates to emergency department settings before and after lockdown due to the COVID-19 pandemic. SOURCES: PubMed, Scopus, and CINAHL. METHODS: A systematic search was conducted following PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-analyses) for studies describing otolaryngologic presentations to emergency department and rapid access clinic settings both in the before-lockdown and after-lockdown periods. The start of after-lockdown period varied based on initiation of lockdown, ranging from March 1st to June 1st of 2020 across general emergency department studies. RESULTS: A total of 14 studies were included in this review. About 10 were general emergency departments, 3 were specifically pediatric emergency departments, and 1 study focused on the geriatric population (>65 years). A total of 13 790 patients were included, with 9446 in the before-lockdown period (68.5%) and 4344 in the after-lockdown period (31.5%). Meta-analysis of proportions for otolaryngologic presentations across general emergency departments was performed. Comparison of weighted proportions found significant differences between before-lockdown and after-lockdown presentation rates for infectious etiologies, tonsillitis specifically, foreign bodies, non-infectious airway issues, and epistaxis among these studies. CONCLUSIONS: The increased proportions of various non-infectious presentations (eg, epistaxis, foreign bodies, and airway issues) following lockdown might be associated with proportional decreases in infectious pathologies, given decreased social contact to prevent SARS-CoV-2 transmission. Overall, it is important for otolaryngologists to recognize what presentations might more commonly be seen and require evaluation and potential intervention in light of a global pandemic.

OBJECTIVE: To provide an updated comparison of apnea-hypopnea index (AHI), oxygen desaturation index (ODI), respiratory disturbance index (RDI), oxygen saturation (O2 sat), and lowest oxyhemoglobin saturation (LSAT) measured by portable sleep study devices (PSSDs) compared to polysomnography (PSG). DATA SOURCES: Primary studies were identified through PubMed, Scopus, CINAHL, and Cochrane. REVIEW METHODS: A systematic review was performed by searching databases from inception through August 2021. Only studies examining simultaneous monitoring of a PSSD and PSG were included. Respiratory indices AHI, ODI, RDI, O2 sat, and LSAT was collected Meta-correlations and meta-regressions were conducted to compare sleep variable measurements between PSSD and PSG. RESULTS: A total of 24 studies (N = 1644 patients) were included. The mean age was 49.5 ± 12.0 (range = 13-92), mean body mass index (BMI) was 30.4 ± 5.7 (range = 17-87), and 69.4% were male. Meta-correlation showed significant associations between PSSD and PSG for AHI (n = 655, r = .888; p < .001), ODI (n = 241, r = .942; p < .001), RDI (n = 313, r = .832; p < .001), O2 sat (n = 171, r = .858; p < .001), and LSAT (n = 197, r = .930; p < .001). Meta-regressions indicated significant predictive correlations for AHI (n = 655; r = .96; p < .001), ODI (n = 740; r = .75; p = .031), RDI (n = 197; r = .99; p = .005), and LSAT (n = 197; r = .85; p = .030), but not for O2 sat (n = 171; r = .31; p = .692). CONCLUSIONS: Respiratory indices correlate strongly between PSSD and PSG, which is further supported by meta-regressions results. PSSD might be a valuable cost and time-saving OSA screening tool.

Objectives: To examine the volume, topics, and reporting trends in the published literature of randomized clinical trials for pharmacologic pain management of pediatric tonsillectomy and adenotonsillectomy and to identify areas requiring further research. Data Sources: PubMed (National Library of Medicine and National Institutes of Health), Scopus (Elsevier), CINAHL (EBSCO), and Cochrane Library (Wiley). Methods: A systematic search of four databases was conducted. Only randomized controlled or comparison trials examining pain improvement with a pharmacologic intervention in pediatric tonsillectomy or adenotonsillectomy were included. Data collected included demographics, pain-related outcomes, sedation scores, nausea/vomiting, postoperative bleeding, types of drug comparisons, modes of administration, timing of administration, and identities of the investigated drugs. Results: One hundred and eighty-nine studies were included for analysis. Most studies included validated pain scales, with the majority using visual-assisted scales (49.21%). Fewer studies examined pain beyond 24 h postoperation (24.87%), and few studies included a validated sedation scale (12.17%). Studies have compared several different dimensions of pharmacologic treatment, including different drugs, timing of administration, modes of administration, and dosages. Only 23 (12.17%) studies examined medications administered postoperatively, and only 29 (15.34%) studies examined oral medications. Acetaminophen only had four self-comparisons. Conclusion: Our work provides the first scoping review of pain and pediatric tonsillectomy. With drug safety profiles considered, the literature does not have enough data to determine which treatment regimen provides superior pain control in pediatric tonsillectomy. Even common drugs like acetaminophen and ibuprofen require further research for optimizing the treatment of posttonsillectomy pain. The heterogeneity in study design and comparisons weakens the conclusions of potential systematic reviews and meta-analyses. Future directions include more noninferiority studies of unique comparisons and more studies examining oral medications given postoperatively.
RESUMO
INTRODUCTION: Non-tuberculous mycobacterial (NTM) infection commonly manifests as subacute or chronic cervicofacial lymphadenitis in immunocompetent children. The optimal management of this pathology remains controversial. OBJECTIVES: This international consensus guideline aims to understand the practice patterns for NTM cervicofacial lymphadenitis and to address the primary diagnostic and management challenges. METHODS: A modified three-iterative Delphi method was used to establish expert recommendations on the diagnostic considerations, expectant or medical management, and operative considerations. The recommendations herein are derived from current expert consensus and critical review of the literature. SETTING: Multinational, multi-institutional, tertiary pediatric hospitals. RESULTS: Consensus recommendations include diagnostic work-up, goals of treatment and management options including surgery, prolonged antibiotic therapy and observation. CONCLUSION: The recommendations formulated in this International Pediatric Otolaryngology Group (IPOG) consensus statement on the diagnosis and management of patients with NTM lymphadenitis are aimed at improving patient care and promoting future hypothesis generation.

OBJECTIVES: Posttransplant lymphoproliferative disorder (PTLD) is a well-recognized complication of solid organ transplantation and commonly affects upper airway lymphoid tissue. Tracheal and laryngeal involvement in patients with PTLD, however, is rare. We present one such case. METHODS: We report the case of a patient with recurrent PTLD involving the larynx and trachea and describe the presentation, evaluation, management, and outcome. RESULTS: An 11-year-old boy who underwent bilateral nephrectomy and renal transplantation as an infant was admitted to the hospital with chronic cough, fever, stridor, and dyspnea. His post-transplantation course was complicated by PTLD in cervical lymph nodes at 9 years of age that was successfully treated with chemotherapy. A computed tomographic scan during his present admission revealed supraglottic swelling, a distal tracheal mass, and paratracheal lymph node enlargement. The patient underwent laryngoscopy and bronchoscopy with biopsy specimens taken from the right laryngeal ventricle and distal trachea. Pathologic examination yielded a diagnosis of Epstein-Barr virus-positive PTLD. The patient was treated with chemotherapy, which resulted in resolution of the airway lesions, as seen on repeat bronchoscopy. CONCLUSIONS: This is the first report, to our knowledge, of recurrent PTLD involving simultaneous lesions in the larynx and the trachea. PTLD in the head and neck can present as lymphoid hypertrophy, airway obstruction, stridor, or cough. A high degree of clinical suspicion is essential for prompt diagnosis of this life-threatening complication.

AIMS: To investigate 3 cases of chronic parotitis secondary to an acute bend in Stensen's duct caused by an enlargement of the masseteric space. RESULTS: Three female patients presented with symptoms consistent with obstructive parotitis including glandular swelling and tenderness during meals. A 10-year-old patient had unilateral facial swelling with enlargement of the masseter muscle and mandible later diagnosed as fibrous dysplasia. Salivary endoscopy showed an acute bend in Stensen's duct secondary to a mass effect. The patient's parotid swelling resolved following debulking of the mandibular mass and sialendoscopy with irrigation. Two adult patients with bilateral parotid involvement presented with bilateral masseteric hypertrophy and dental wear facets consistent with bruxism. Salivary endoscopy revealed bilateral kinking of Stensen's duct with jaw closure. Both patients improved symptomatically following nightly bite guard use and ultrasound-guided Botox injections of the masseter muscle and parotid. CONCLUSION: Obstructive parotitis is rarely caused by an acute masseteric bend. Diagnosis of a kinking Stensen's duct is aided with salivary endoscopy and imaging to determine the precipitating pathology. In the case of masseteric hypertrophy, symptomatic improvement can be achieved with Botox-induced atrophy of masseteric hypertrophy or with surgical reduction for associated fibrous dysplasia.

Vascular anomalies fall into two groups: vascular neoplasms and vascular malformations. Their behaviors differ, therefore they require different methods of management. Vascular lesions of the airway involve some degree of airway obstruction, although this may not be their primary manifestation. Areas of narrowing along this pathway have functional consequences for respiration, swallowing, speech, and growth, as well as overall development and quality of life. Small amounts of airway narrowing may be significant, and there are important differences between the adult and pediatric airway. Although lesions can be distractingly large, deforming, or completely hidden from view, the clinician should focus on evaluating for impairments of function. Awake flexible fiberoptic laryngoscopy is the first diagnostic step. Imaging is critical to both diagnosis and management of vascular anomalies, as specific diagnoses lead to varying treatment options. Management of vascular anomalies of the airway requires knowledge of treatment options and multidisciplinary care.
