RESUMEN
Obstructive sleep apnea syndrome (OSAS) is a common pediatric disorder characterized by recurrent events of partial or complete upper airway obstruction during sleep which result in abnormal ventilation and sleep pattern. OSAS in children is associated with neurobehavioral deficits and cardiovascular morbidity which highlights the need for prompt recognition, diagnosis, and treatment. The purpose of this state-of-the-art review is to provide an update on the evaluation and management of children with OSAS with emphasis on children with complex medical comorbidities and those with residual OSAS following first-line treatment. Proposed treatment strategies reflecting recommendations from a variety of professional societies are presented. All children should be screened for OSAS and those with typical symptoms (e.g., snoring, restless sleep, and daytime hyperactivity) or risk factors (e.g., neurologic, genetic, and craniofacial disorders) should undergo further evaluation including referral to a sleep specialist or pediatric otolaryngologist and overnight polysomnography, which provides a definitive diagnosis. A cardiology and/or endocrinology evaluation should be considered in high-risk children. For the majority of children, first-line treatment is tonsillectomy with or without adenoidectomy; however, some children exhibit multiple levels of airway obstruction and may require additional evaluation and management. Anti-inflammatory medications, weight loss, and oral appliances may be appropriate in select cases, particularly for mild OSAS. Following initial treatment, all children should be monitored for residual symptoms and polysomnography may be repeated to identify persistent disease, which can be managed with positive airway pressure ventilation and additional surgical approaches if required.

OBJECTIVES: Although evidence-based Clinical Practice Guidelines (CPGs) have specified postoperative admission criteria for pediatric tonsillectomy, there is substantial variation in guideline implementation and adherence among otolaryngologists in practice. We aimed to assess pediatric otolaryngologists' post-tonsillectomy admission practices and to examine patient and surgeon factors associated with differences in admission practices. METHODS: An electronic cross-sectional survey was distributed to members of the American Society of Pediatric Otolaryngology (ASPO) to determine current practices regarding admission practices following pediatric tonsillectomy. Chi-square and Fisher's exact tests were performed to compare differences in adherence to tonsillectomy CPGs by respondent characteristics. RESULTS: The survey was sent to 644 pediatric otolaryngologists with a response rate of 19.1%. 37% of respondents reported "always" and 60% "often" using the Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) CPG to guide decision for admission. Years in practice was the factor most strongly associated with admission practices, with 10 or fewer years in practice significantly correlated with stricter adherence to the AAO-HNS CPG of overnight observation when Apnea-Hypopnea Index (AHI) ≥10, age <3 years, or O2 nadir <80%) (OR 4.2, p <0.001), as well as specific individual criteria such as an AHI ≥10 (OR 4.1, p = 0.03). Respondents in an academic practice setting were more likely to admit children <3 years of age than those in private practice (OR 5.0, p = 0.01). CONCLUSION: Admission practices varied among pediatric otolaryngologist survey respondents, and strict AAO-HNS CPG adherence was associated with fewer years in practice and academic practice setting. These results suggest that further study investigating factors influencing guideline adherence and post-tonsillectomy admission practices is warranted.

Background: To measure the impact of an intensive eight-week postgraduate year one (PGY-1) otolaryngology bootcamp on the acquisition and retention of otolaryngology residents' procedural skills compared to the traditional method of skill acquisition through clinical exposure. Methods: Residents at our institution were evaluated on their performance of flexible laryngoscopy, suture ligature, and rigid bronchoscopy setup at three time points: pre-bootcamp, one-week post-bootcamp, and one-year post-bootcamp. Video recordings were scored by two blinded faculty reviewers using a multipoint rating system. A control group of rising postgraduate year two (PGY-2) residents who did not participate in bootcamp were recorded performing these same skills. Scores in the three skills were compared between groups via t-tests. The eight-week bootcamp curriculum for PGY-1s was held at the Montefiore Einstein Center for Innovation in Simulation at Albert Einstein College of Medicine/Montefiore Medical Center. The participants were two classes of PGY-1 residents (n=8) at our institution who participated in a bootcamp at the beginning of residency, and one class of rising PGY-2 residents (n=3) who did not participate in a bootcamp (control group). Results: A comparison of pre-bootcamp scores to one-week post-bootcamp scores showed significant improvement in suture ligature ( P<0.05) and rigid bronchoscopy ( P<0.05), but no difference in flexible laryngoscopy ( P=0.54). Suture ligature ( P=0.09) and rigid bronchoscopy ( P=0.25) skills were not significantly different from one-week post-bootcamp to one-year post-bootcamp; however, a significant skill improvement was observed in flexible laryngoscopy ( P<0.05). By June of PGY1 year, the two bootcamp cohorts were similar to controls in all three skills: flexible laryngoscopy ( P=0.05), rigid bronchoscopy ( P=0.26), and suture ligature ( P=0.10). Conclusions: Participation in PGY-1 bootcamp was associated with improved acquisition and short-term retention of basic procedural skills, suggesting that bootcamps can be an effective arena to teach basic skills in otolaryngology. PGY-1 bootcamp is a promising arena for multi-institutional development.
RESUMEN
STUDY OBJECTIVES: Our objective was to determine the prevalence of elevated right ventricular pressure (RVP) as a surrogate marker for pulmonary hypertension in children with obstructive sleep apnea syndrome (OSAS) undergoing echocardiography. METHODS: This was a retrospective chart review of children ages 2-21 years diagnosed with OSAS by an overnight polysomnogram who underwent cardiac echocardiogram to screen for pulmonary hypertension within 6 months of polysomnogram in a tertiary inner-city pediatric hospital. The primary outcome was elevated RVP defined by estimated RVP ≥ 25 mm Hg above right atrial pressure or ventricular septal configuration consistent with elevated RVP. RESULTS: A total of 174 children were included. The median (interquartile range) age was 8.9 (5.5-13.1) years with 59.2% male, 41.4% Hispanic, and 25.9% non-Hispanic Black patients. The prevalence of obesity was 72.0% and severe or very severe OSAS was present in 93.1%. The median (interquartile range) apnea-hypopnea index was 28.3 events/h (18.8-52.7 events/h). Seven children (4.0%) had elevated RVP. There was no association between elevated RVP and age, sex, race, body mass index percentile, apnea-hypopnea index, oxygen nadir, or severe OSAS (apnea-hypopnea index ≥ 10 events/h). CONCLUSIONS: Elevated RVP was rare and was not associated with OSAS severity. The prevalence in this cohort is higher than the prevalence of pulmonary hypertension noted in similar studies (0%-1.8%), which may be related to differences in methodology or unassessed cohort characteristics. Further effort to determine the optimal role for pulmonary hypertension screening in pediatric OSAS is needed. CITATION: Bitners AC, Arens R, Mahgerefteh J, et al.

STUDY OBJECTIVES: The biomechanical basis of obstructive sleep apnea syndrome (OSAS) may influence upper airway dynamics. In this study, we investigate dynamic changes during respiration in wakefulness and sleep in obese adolescents with and without OSAS. METHODS: Respiratory-gated dynamic magnetic resonance imaging (MRI) at the retropalatal and retroglossal regions was performed with simultaneous measurement of SpO2 and nasal-oral mask airflow and pressure. Airway cross-sectional area (CSA) was determined using AMIRA. Percent change in CSA was calculated from five continuous tidal breaths in states of wakefulness and sleep. Mixed effects models were used to evaluate interactions between group (OSAS/control), site (retropalatal/retroglossal), and stage (wake/sleep). RESULTS: We studied 24 children with OSAS (mean age 15.49 ± 2.00 years, mean apnea-hypopnea index [AHI] 16.53 ± 8.72 events/h) and 19 controls (mean age 14.86 ± 1.75 years, mean AHI 2.12 ± 1.69 events/h). Groups were similar in age, sex, height, weight, and BMI Z-score. Participants with OSAS had a 48.17% greater increase in percent change of airway CSA during sleep than controls (p < 0.0001), while there was no difference between groups during wakefulness (p = 0.6589). Additionally, participants with OSAS had a 48.80% increase in percent change of airway CSA during sleep as compared with wakefulness (p < 0.0001), whereas no such relationship was observed in controls (p = 0.5513). CONCLUSIONS: This study demonstrates significant effects of sleep on upper airway dynamics in obese children with OSAS. Dynamic MRI with physiological data can potentially provide further insight into the biomechanical basis of OSAS and assist in more effective management.

OBJECTIVES: To compare the rates of skin-related complications and accidental decannulation in pediatric patients who received Velcro® ties versus twill ties during the early postoperative period following tracheotomy. The rates of skin-related complications and accidental decannulation in patients with Velcro® ties was hypothesized to differ from those in patients with twill ties. METHODS: Medical records of 109 patients ≤18 years old who underwent elective tracheotomy were reviewed: 70 received twill ties and 39 received Velcro® ties. Patients were followed for the first seven postoperative days. The primary outcome was skin-related complications, which were further categorized into mild (irritation) and severe (breakdown). The secondary outcome was accidental decannulation. Rates of skin-related complication and accidental decannulation were compared across the two groups using chi-square analysis. RESULTS: Skin irritation occurred in 32 patients (45.7%) with twill ties and 10 patients (25.6%) with Velcro®. Skin breakdown occurred in 20 patients (28.6%) with twill ties and 6 patients (15.4%) with Velcro®. There were no accidental decannulation events. The use of Velcro® ties was associated with a decreased rate of skin irritation (OR: 0.41; 95% CI: 0.17-0.97; Pâ¯=â¯0.039). CONCLUSIONS: The use of Velcro® ties was associated with a decrease in the rate of skin irritation. There were no accidental decannulation events. These findings support the use of Velcro® ties at the time of pediatric tracheotomy placement.
