Objective: Validation of a contemporary International Classification of Diseases, 10th Revision, Clinical Modification (ICD‐10‐CM) congenital esophageal atresia/tracheoesophageal atresia (EA/TEF) cohort in the Pediatric Health Information System (PHIS) database. Study Design: Database study, validation. Setting: Tertiary care center. Methods: Search methods used to validate an ICD‐9‐CM EA/TEF cohort in PHIS were modified for ICD‐10‐CM. A retrospectively and prospectively maintained clinical database at a single high‐volume EA/TEF center was used for comparison. Patients treated between October 1, 2015 and July 31, 2022 were included. Searches progressively narrowed the cohort by ICD‐10‐CM diagnosis codes, expansion to include incorrectly coded as 'iatrogenic, age less than 30 days, and use of at least 1 ICD‐10‐CM procedure code. Results of PHIS data and institution data were compared for accuracy. Results: The most refined search of PHIS and the EA/TEF clinical database yielded 93 and 84 patients, respectively. The sensitivity was 99% and positive predictive value was 94%. A PHIS search using these methods and encompassing 49 children's hospitals yielded an EA/TEF cohort of 2479 patients. Conclusion: We present a validated search method in the PHIS database to identify a high‐fidelity cohort of EA/TEF patients for multi‐institutional study. We have demonstrated that a carefully maintained clinical database may be used to validate cohorts in PHIS. This cohort allows for improved practice variability and outcomes study of EA/TEF patients. Similar methods may be employed to generate other rare disease cohorts in PHIS. Level of Evidence: Level 4. [ABSTRACT FROM AUTHOR]

Introduction: Children undergoing cervical and/or thoracic operations are at risk for recurrent laryngeal nerve injury, resulting in vocal fold movement impairment (VFMI). Screening for VFMI is often reserved for symptomatic patients. Objective: Identify the prevalence of VFMI in screened preoperative patients prior to an at‐risk operation to evaluate the value of screening all patients at‐risk for VFMI, regardless of symptoms. Methods: A single center, retrospective review of all patients undergoing a preoperative flexible nasolaryngoscopy between 2017 and 2021, examining the presence of VFMI and associated symptoms. Results: We evaluated 297 patients with a median (IQR) age of 18 (7.8, 56.3) months and a weight of 11.3 (7.8, 17.7) kilograms. Most had a history of esophageal atresia (EA, 60%), and a prior at‐risk cervical or thoracic operation (73%). Overall, 72 (24%) patients presented with VFMI (51% left, 26% right, and 22% bilateral). Of patients with VFMI, 47% did not exhibit the classic symptoms (stridor, dysphonia, and aspiration) of VFMI. Dysphonia was the most prevalent classic VFMI symptom, yet only present in 18 (25%) patients. Patients presenting with a history of at‐risk surgery (OR 2.3, 95%CI 1.1, 4.8, p = 0.03), presence of a tracheostomy (OR 3.1, 95%CI 1.0, 10.0, p = 0.04), or presence of a surgical feeding tube (OR 3.1, 95%CI 1.6, 6.2, p = 0.001) were more likely to present with VFMI. Conclusion: Routine screening for VFMI should be considered in all at‐risk patients, regardless of symptoms or prior operations, particularly in those with a history of an at‐risk surgery, presence of tracheostomy, or a surgical feeding tube.

Objectives/Hypothesis: The recurrent laryngeal nerve (RLN) is at risk during pediatric cervical, thoracic, and cardiac surgery. We aim to determine the feasibility and effectiveness of RLN monitoring techniques in all pediatric patients. Study Design: Retrospective case series. Methods: Retrospective review of patients/procedures with RLN(s) at risk and RLN monitoring at Boston Children's Hospital July 2019–October 2020. Primary outcomes: pre/postoperative vocal fold mobility by awake flexible fiberoptic laryngoscopy (FFL). Results: One hundred one patients (median [interquartile range, IQR] age 14.6 months [4.6–49.7 months], weight 10 kg [5.2–16.2 kg]) underwent 122 procedures with RLN(s) at risk. RLN monitoring attempted 111 cases, successful 96 (84%). Surgical indications: esophageal atresia/tracheoesophageal fistula, and tracheobronchomalacia. Sixty‐two (56%) procedures in reoperative field. Median follow‐up 112 days (IQR 41–230). Pre/postoperative FFL performed 84 procedures (69%), 19 new postoperative RLN injuries (16%), median age 12 months, reoperative fields 11 (18%). Prass probes: 34 cases (28 successful, 82%), 6 injuries (18%), age 12.2 (5.8–23.6) months. Dragonfly electrodes: 45 cases (37 successful, 82%), 8 injuries (18%), age 7.5 (3.8–19) months. Nerve integrity monitoring (NIM) integrated electrode endotracheal tube: 33 cases (33 successful, 100%), 5 injuries (15%), age 90 (58.8–136.7) months. Automatic periodic stimulation (APS): 16 cases, 13 successful (81%), four injuries (25%), age 7.2 (5.3–20.6) months. NIM RLN monitoring is significantly more successful than Prass, Dragonfly (95%CI −0.3 to 0.02, P =.02; and 95%CI 0.05–0.31, P =.008). Rates of injury are not different between types of RLN monitoring (P =.94), with APS use (P =.47), or with monitoring success (95%CI −0.36 to 0.09, P =.28). Conclusions: RLN monitoring is feasible in pediatric patients of all ages. Although NIM type RLN monitoring success is superior, all forms offer similar rates of nerve protection.

Objectives: Gender disparity exists in medicine, such as differences in pay and promotion opportunities. We hypothesize that there is also a gender difference in graduate medical education as manifested by operative case volume. This study compares surgical case volume by gender for graduating US otolaryngology residents.Study Design: Cohort study.Methods: With data use approval from the Accreditation Council for Graduate Medical Education, we evaluated the key indicator case log summaries of graduating otolaryngology residents from 2009-2017. Mean and standard deviation were used for all cases, and t-tests were used to compare cases by resident gender. The Bonferroni method was used to adjust for multiple comparisons across years.Results: Data from 1740 male and 804 female residents were evaluated. Across all years, the average number of key indicator cases reported was 778.8 and 813.6 by female and male residents, respectively, with an average difference of 34.8 cases per graduating year (95% confidence interval [CI] 19.4, 50.2; P < .001). When a resident self-reported the role of resident surgeon/supervisor, the average number of key indicator cases reported was 602.6 and 643.9 by female and male residents, respectively, with an average difference of 41.3 cases per graduating year (95% CI, 28.0, 54.6; P < .001).Conclusion: Gender-based discrepancies in surgical case volume exist among graduating otolaryngology residents. This disparity is partially attributed to the self-reported role in the surgery. This study has identified those discrepancies so that training programs can implement strategies to ensure improved gender parity.Level Of Evidence: 2b Laryngoscope, 130:1651-1656, 2020.

Objective: To discuss the presentation, evaluation, and management of pediatric laryngeal web.Study Design: Retrospective case series.Setting: Single tertiary care center.Subjects: All patients with laryngeal web at Boston Children's Hospital in the past 22 years.Methods: No exclusion criteria. Charts mined for age at presentation, presenting symptoms, degree/location of web, associated syndromes, number/type of surgical procedures, and postoperative outcomes.Results: Thirty-seven patients were included (13 male, 24 female). Average age at diagnosis was 3.7 years (0-19.5 years). Mean follow-up was 4.4 years (range, 0-16.4 years). There were 26 congenital webs (70.2%) and 11 acquired webs (29.8%). Presenting symptoms were vocal (29 patients, 78.4%) and respiratory (22 patients, 60%). Underlying syndromes or synchronous airway lesions included the following: premature (n = 5), congenital heart disease (n = 18), subglottic stenosis (n = 5), 22q11.2 deletion syndrome (n = 10), and recurrent respiratory papillomatosis (n = 4). There were 20 type 1 webs, 6 type 2 webs, 8 type 3 webs, and 3 type 4 webs; 10 had subglottic extension of the laryngeal web. Twelve patients were managed conservatively with observation. Eighty-four interventions were performed: 18 open and 66 endoscopic (sharp division, 32; dilation, 33; mitomycin C, 14; laser, 5; keel, 6; triamcinolone injection, 8; stent, 15; removal of granulation tissue, 5). Tracheotomy was required in 11 patients, and 5 patients were decannulated. Voice improved in 12 patients, with respiratory symptoms in 12 patients. Web recurred in 17 patients. One patient died due to airway complications.Conclusions: Pediatric laryngeal web is an uncommon but challenging lesion. Patients need to be evaluated for comorbid syndromes and synchronous airway lesions. Management includes open and endoscopic procedures. Procedures should be tailored to the child's presentation.
