Rate and management of tympanic membrane perforations in children with Down syndrome and middle ear disorder.

OBJECTIVE: To characterize the management and outcomes of observation versus surgical intervention of tympanic membrane (TM) perforations in children with Down syndrome (DS). In addition, to estimate the prevalence of TM perforations in children with DS. METHODS: Retrospective case review analysis of TM perforation rate in children with DS with history of tympanostomy tube (TT) insertion at a tertiary pediatric referral center. Patients were divided into observation or surgical intervention groups and then further evaluated for the type of intervention, the number of required procedures, and success rate of hearing improvement. Risk factors contributing to perforations were analyzed, including TT type, number of TT surgeries, and perforation size. RESULTS: The TM perforation rate in children with DS with TT history was 7.0 %. Tympanoplasty was performed in 41.5 % of perforated ears with a success rate of 53.1 %. There was no statistical difference between the surgical intervention and observation groups regarding perforation characteristics or TT number and type, but the surgical intervention cohort was older. Hearing improvement based on postoperative pure tone average (PTA) threshold was noted in the successful surgical intervention group. CONCLUSION: The rate of TM perforations in children with DS after TTs is comparable to the general population. Improved PTA thresholds were noted in the surgical success group influencing speech development. The overall lower success rate of tympanoplasty in patients with DS emphasizes the need to factor in the timing of surgical intervention based on the predicted age of Eustachian tube maturation.

Measuring the Impact of a Delay in Care on Pediatric Otolaryngologic Surgery Completion.

Objective: To determine if postponement of elective pediatric otorhinolaryngology surgeries results in a change in overall healthcare utilization and if there is any commensurate impact on disease progression. Methods: We identified patients ≤18 years of age whose surgeries were postponed at the onset of the COVID-19 pandemic-related shutdown. We then tracked patients' rate of and patterns of rescheduling surgery. Surveys were also sent to caregivers to better characterize his/her decision regarding moving forward with his/her child's surgery during COVID-19. Results: A total of 1915 pediatric patients had elective surgeries canceled, of which 992 (51.8%) were rescheduled within 4 months. No difference in rates of rescheduling was identified based on race or ethnicity. Patients who were scheduled for tonsillectomies and/or adenoidectomies were 1.22 times more likely to reschedule compared to those patients with other planned procedures (CI: 1.02-1.46). A total of 95 caregivers at two hospitals completed surveys: 44 (47.4%) rescheduled their child's surgery. Most caregivers who rescheduled were concerned their child's disease could impact their future (n = 14, 32%). Conclusions: Just over half of patients who had pediatric otolaryngologic surgery canceled during a period of social distancing went on to have surgery within a 4-month timeframe. This reflects the dependence of pediatric otolaryngologic surgery on environmental exposures and may represent a potential target for prevention and management of some pediatric otolaryngology diseases.

Continuous Positive Airway Pressure Titration During Pediatric Drug Induced Sleep Endoscopy.

OBJECTIVE: To observe the degree of airway collapse at varying levels of continuous positive airway pressure (CPAP) during drug pediatric induced sleep endoscopy. METHODS: Using our institutional anesthesia protocol for pediatric DISE procedures, patients were anesthetized followed by evaluation of the nasal airway, nasopharynx, velum, hypopharynx, arytenoids, tongue base, and epiglottis. CPAP titration was performed under vision to evaluate the degree of airway collapse at the level of the velum. Comparison was made with pre-operative polysomnography findings. RESULTS: Twelve pediatric patients underwent DISE with intraoperative CPAP titration. In 7/12 patients, DISE observed CPAP titration was beneficial in elucidating areas of obstruction that were observed at pressures beyond those recommended during preoperative sleep study titrations. In 3 patients, DISE observations provided a basis for evaluation in children not compliant with sleep study CPAP titration testing. With regard to regions effected, airway collapse was observed at the velum and oropharynx to a greater degree when compared with the tongue base and epiglottis. CONCLUSION: DISE evaluation of the pediatric patient with obstructive sleep apnea may present a source for further patient evaluation with respect to CPAP optimization and severity of OSA assessment, particularly in syndromic patients.

Volumetric brain magnetic resonance imaging analysis in children with obstructive sleep apnea.

OBJECTIVES: Pediatric Obstructive Sleep Apnea (OSA) is associated with neurocognitive deficits. Cerebral structural alterations in the frontal cortex, cerebellum, and hippocampus have been reported in adult OSA patients. These brain areas are important for executive functioning, motor regulation of breathing, and memory function, respectively. Corresponding evidence comparing cerebral structures in pediatric OSA patients is limited. The objective of this study is to investigate MRI differences in cortical thickness and cortical volume in children with and without OSA. STUDY DESIGN: Prospective, single institutional case-control study. METHODS: Forty-five children were recruited at a pediatric tertiary care center (27 with OSA; mean age 9.9 ± 1.9 years, and 18 controls; mean age 10.5 ± 1.0 years). The OSA group underwent magnetic resonance imaging (MRI), polysomnography (PSG) and completed the Pediatric Daytime Sleepiness Scale (PDSS) and the Child's Sleep Habits Questionnaire (CSHQ). High-resolution T1-weighted MRI was utilized to examine cortical thickness and gray and white matter volume in children with OSA compared to a healthy group of demographically-comparable children without OSA selected from a pre-existing MRI dataset. RESULTS: Children with OSA showed multiple regions of cortical thinning primarily in the left hemisphere. Reduced gray matter (GM) volume was noted in the OSA group in multiple frontal regions of the left hemisphere (superior frontal, rostral medial frontal, and caudal medial frontal regions). Reduced white matter (WM) volume in both the left and right hemisphere was observed in regions of the frontal, parietal, and occipital lobes in children with OSA. CONCLUSION: This study noted differences in cortical thickness and GM and WM regional brain volumes in children with OSA. These findings are consistent with other pediatric studies, which also report differences between healthy children and those with OSA. We found that the severity of OSA does not correlate with the extent of MRI alterations.

Pediatric otolaryngology workflow changes in a community hospital setting to decrease exposure to novel coronavirus.

OBJECTIVES: To develop a workflow algorithm for physicians and staff to decrease cross contamination and minimize exposure to Coronavirus Disease -19 (COVID-19) in pediatric otolaryngology at a community pediatric hospital. METHODS: PubMed and Google Scholar searches were carried out using the keywords. Pertinent clinical information related to pediatric otolaryngology was reviewed from journals, Texas Medical Board guidelines as well as institutional guidelines. Updated information from the Centers for Disease Control through social media was identified via Google search. STUDY DESIGN: Safety measures and clinical work-flow protocols were developed to protect patients, families, and staff. Protocols included a rotation schedule for providers and ancillary staff, guidelines for in-clinic visits and alteration to surgical block and surgical case cadence to minimize exposure of providers and staff to COVID-19. Algorithms and guidelines were reviewed and revisions made at each phase of the pandemic related to in-clinic visits, telemedicine visits, and surgical cases. CONCLUSION: In the era of the COVID-19 pandemic, otolaryngologists and pediatric otolaryngologists are amongst sub-specialties with an increased risk of exposure. It is imperative that a modification in clinical workflow is created to minimize the risk of exposure to providers and staff while continuing to provide care to patients. PRACTICE IMPLICATIONS: The COVID-19 pandemic continues to evolve and change rapidly. The described guidelines and workflow algorithm serve as tools to help pediatric otolaryngologists protect themselves and their staff and patients during this global crisis.

Airway protection & patterns of dysphagia in infants with down syndrome: Videofluoroscopic swallow study findings & correlations.

INTRODUCTION: Down syndrome is a genetic condition that affects 1:737 births. Along with cardiac, otolaryngologic, and developmental anomalies, infants with Down syndrome can have swallowing difficulties resulting in respiratory infections. This study aims to characterize the airway protection and dysphagia seen in infants with Down syndrome. METHODS: This is a retrospective chart review of infants with Down syndrome who underwent videofluoroscopic swallow studies (VFSS) from 2008 to 2018 at a tertiary children's hospital. Demographic data and VFSS findings were collected. RESULTS: 89.8% (114/127) of infants presented with at least one element of oral dysphagia, while 72.4% (92/127) had at least one element of pharyngeal dysphagia. Sucking skills were classified as abnormal in 63.7% of the patients and bolus formation-control was determined to be deficient (abnormal) in 62.2% of the patients. Oral residuals were present in 37.8% of the patients. With regard to pharyngeal phase, the swallow initiation was considered abnormal in 53.5% of the patients. Pharyngeal residue was present in 17.3% and pharyngo-nasal reflux was present in 27.5% of the patients. CONCLUSIONS: Swallowing assessments in infants with Down syndrome suspected of dysphagia should be considered, especially in those with any alterations in pulmonary health.
