Objectives: Posterior glottic diastasis (PGD) is an underappreciated etiology of dysphonia in patients with prior airway reconstruction or prolonged intubation. In endoscopic posterior cricoid reduction (ePCR), cricoid is removed to minimize the posterior glottic gap. Dynamic voice computed tomography (DVCT) permits visualization of the posterior glottis, estimating the amount of cricoid to be removed. Posterior glottic gaps in patients undergoing ePCR were compared to non‐dysphonic patients to describe pediatric PGD and establish surgical parameters for ePCR. Methods: DVCTs performed in non‐dysphonic patients and dysphonic patients undergoing ePCR from 2014 to 2023 were reviewed. EPCR operative reports were queried. Pre‐ and postoperative Pediatric Voice Handicap Index (pVHI) and Consensus Auditory‐Perceptual Evaluation of Voice (CAPE‐V) scores and aerodynamic measures were reviewed. Results: Seventeen pediatric patients who underwent ePCR and 19 non‐dysphonic patients were included. Posterior glottic gaps were significantly larger in the dysphonic group (median 2.4 mm [IQR: 2.0, 2.8] vs. 1.3 mm [IQR: 1.1, 1.7], p < 0.001). Mean width of the cricoid removed was 1.6 mm (SD 0.4 mm). Mean (SD) pre‐ and postoperative pVHI scores were 55.5 (19.9) and 34.6 (16.0; p < 0.001). Mean (SD) pre‐ and postoperative CAPE‐V scores were 52.7 (15.4) and 36.5 (20.4; p < 0.001), respectively. Conclusions: Children in this cohort tolerated an average 1.3 mm posterior glottic gap without dysphonia. Dysphonic patients with PGD had a median 2.4 mm gap and underwent cricoid reduction by 1.6 mm. All ePCR patients demonstrated improvement in dysphonia. Results seek to optimize the management of pediatric PGD and present a safe and effective amount of cricoid to remove during ePCR.

Objective: Limited investigation of factors potentially contributing to treatment choice in early‐stage glottic carcinoma (EGC) has been performed with large‐scale data. The National Cancer Database (NCDB) represents >72% of all new cancer cases in the United States. We hypothesized that NCDB variables may lend insight into treatment decisions between surgery and radiation for EGC. Methods: The NCDB was queried for all cases of T1‐2 N0 M0 glottic carcinoma from 2004 to 2016. We used multivariable logistic regression analysis to examine factors associated with first‐line treatment modality: radiation therapy (RT) versus surgery. All reported odds ratios (OR) were adjusted for age, gender, race, insurance, residence in a metropolitan area, region, and facility volume. Results: 34,991 EGC patients received treatment: 6,687 (19%) surgery; 20,289 (58%) RT; and 8,015 (23%) surgery and RT. OR for receiving RT (vs. surgery alone) were >2 for: more advanced T stage cancers (OR 2.5 [95%CI: 2.3, 2.7]), treatment at non‐academic facilities (OR 2.8, [95%CI: 2.6, 3.0]), and shorter travel distances to treatment centers (OR 2.2, [95%CI: 2.0, 2.4]). Surgery was more likely with treatment in the western US, higher income, private insurance, living in a metropolitan (vs. non‐metropolitan) area, female gender, older age, and low facility volume. Hispanic ethnicity, education level, and race were not associated with treatment type in the multivariable model. Conclusion: Most patients in the NCDB receive first‐line treatment with radiation for EGC, and this decision is associated with various tumor, patient, and treatment facility characteristics.

Objective: Tracheoesophageal fistula and esophageal atresia (TEA) and laryngeal cleft (LC) can coexist in some patients. The surgery‐specific success rate of LC repair in children with associated TEA has not been well described. The aim of the study is to determine if the history of TEA alters the LC repair outcomes. Study Design: Case series with chart review. Setting: Single‐institution academic medical center. Method: A retrospective review was conducted of patients with LC with and without TEA repair between January 2001 and November 2020. Data collected and analyzed included demographics and clinical characteristics, LC type, and LC with TEA timing of repairs. Results: An overall 282 patients met the inclusion criteria of LC repair: LC (n = 242, 85.8%) and LC + TEA (n = 40, 14.2%). Revision repair was required in 43 patients (15.2%) with 8 (2.8%) needing a second revision repair. The first LC revision rate in the LC group was 36/242 (14.9%) as compared with 7/40 (17.5%) in the LC + TEA group (P =.67). The second LC revision rate in the LC and LC + TEA groups was 7 (2.9%) and 1 (2.4%), respectively. The median time to revision was 5.1 months (interquartile range, 3.45–10.6) in the LC group as compared with 29.2 months (interquartile range, 4.8–44.2) in the LC + TEA group (P =.06). Conclusion: The incidence of TEA and LC was 14.2% in our study. Based on our findings, history of TEA repair is not associated with a higher revision rate vs LC alone. The history of TEA repair did not alter the outcomes of LC repair. [ABSTRACT FROM AUTHOR]

Objectives/Hypothesis: To develop a reproducible and consistent chronic subglottic stenosis (SGS) in an endoscopic animal model. Study Design: Prospective study. Methods: We conducted a prospective study using New Zealand white rabbits. Chronic SGS was induced endoscopically by Bugbee electrocautery to 50% to 75% of the subglottic area's circumference, followed by 4‐hour endotracheal intubation. The rabbit airways were endoscopically assessed and sized with uncuffed endotracheal tubes (ETTs) before the injury, during follow‐up, and at the endpoints. There were four endpoints: 2, 4, 6, and 8 weeks post SGS induction. Animals were humanely euthanized for histopathological examination of the subglottic injury site and microscopic measurement of the cricoid lumen. Results: Twenty‐two rabbits reached the endpoints, and 18 rabbits developed chronic SGS. ETT size significantly decreased by 0.5 from preinjury to the endpoint in all groups, P <.001. Control median cricoid lumen measurements were 20.48 mm2, the median cricoid lumen measurement for the 2 weeks endpoint was 14.3 mm2, 4 weeks 11.69 mm2, 6 weeks 16.03 mm2, and 8 weeks endpoint median was 16.33 mm2. Histopathological examination showed chronic scar tissue and new cartilage formation at the cricoid level, mainly at the posterior subglottic injury site starting from 4 weeks postinjury. Collagen staining revealed substantial amounts of organized collagen and different collagen orientation starting 4 weeks postinjury lasting until 8 weeks postinjury. Conclusion: We developed an animal model to study chronic SGS. This model will be utilized to compare different endoscopic treatment interventions in acute SGS versus chronic SGS and further define the molecular basis of SGS.

Objectives: Post airway reconstruction dysphonia (PARD) is common and has a significant effect on the quality of life of patients. Vocal fold injection augmentation (VFIA) is one treatment that can be used to improve glottic insufficiency in some patients. The goal of this study was to characterize the use and outcomes of VFIA for PARD. Methods: Retrospective chart review from January 2007 to July 2018 at a tertiary pediatric care center. Consecutive patients with PARD who underwent VFIA, who had a preoperative voice evaluation and a follow-up evaluation within 3 months after VFIA (fat, carboxymethylcellulose gel, hyaluronic acid). Results: Thirty-four patients (20 female) underwent VFIA. The mean age at the time of the injection was 13.6 years (SD 6.1). Twenty patients (58.8%) had a history of prematurity and a mean of 1.8 open airway surgeries. After injection, 29/34 patients (85.3%) noted a subjective voice improvement. The baseline Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) overall severity score decreased by a mean of 5.7 (SD = 19.6) points, P =.12. Total pediatric Voice Handicap Index (pVHI) improved by 6.0 (SD = 19.5) points, from 57.4 (SD = 20.0) to 51.4 (SD = 17.2), P =.09. Functional pVHI subscore demonstrated a significant improvement, with a decrease of 3.4 (SD = 7.3) points, P =.02. All procedures were performed as an overnight observation and no complication occurred. Conclusion: Patients with PARD represent a complex subset of patients. VFIA is a straightforward intervention that may improve voice perception. Many patients reported subjective improvement despite minimal objective measurement. Further work is warranted to elucidate the role of injection in management of PARD [ABSTRACT FROM AUTHOR]

Objectives: Airway reconstruction for subglottic and tracheal stenosis is often successful in achieving tracheostomy decannulation and improving airway symptoms. However, one common reason for late failure is development of a tracheal A‐frame deformity, which can necessitate additional surgery. Although knowledge of this deformity exists, the incidence and risk factors have not been reported. This study seeks to determine the incidence of A‐frame following airway reconstruction and define factors that correlate with development of this deformity. Study Design: Retrospective case series. Methods: Patients under 21 years of age undergoing open airway reconstruction at our institution between January 2005–December 2006 were retrospectively reviewed. Demographic data, comorbidities, airway history/reconstruction type, and follow‐up airway findings were examined using multivariable logistic regression. Kaplan–Meier curves were used to examine time to A‐frame repair. Results: Two hundred patients underwent airway reconstruction and 69 (34.5%) developed an A‐frame deformity. History of tracheostomy was the most significant contributor to A‐frame development (P <.0001). Double‐ versus single‐stage procedures were not associated with increased odds of A‐frame development (P =.94), however, patients undergoing resection procedures as opposed to laryngotracheal reconstruction (LTR) with cartilage grafts had a significantly lower chance of developing this deformity (P =.004). Of the patients with an A‐frame, 27 (39%) required further surgical intervention. Conclusion: Approximately one‐third of patients undergoing airway reconstruction developed a tracheal A‐frame deformity, with a significantly higher rate among patients with a history of tracheostomy and those undergoing LTR. Patients should be followed long term to assess for the development of an A‐frame. Level of Evidence: IV Laryngoscope, 131:E1363–E1368, 2021 [ABSTRACT FROM AUTHOR]

Objectives/hypothesis: The male singing voice through puberty undergoes many changes that present challenges for the singer and choral director. The purpose of this study was to discuss the endoscopic findings seen in prepubescent choir singers.Study Design: Single-institution prospective study.Methods: Subjects were recruited from the Cincinnati Boychoir and were described as Cooksey stage unchanged or mid-voice I, as described by the Boychoir artistic director. Vocal history was obtained via questionnaire at the initial visit. Subjects with known laryngeal pathologies were excluded. Endoscopic laryngeal examinations were performed using videoendoscopy. During examination, each subject sang four discrete frequencies. Findings of the endoscopic exam were judged by a board-certified pediatric otolaryngologist specializing in pediatric voice.Results: We evaluated 28 subjects prior to vocal maturation. Their age range was 8 to 13 years old (mean = 10.2 ± 1.2 years). The singing voice category of all 28 subjects was described as soprano vocal range by the Boychoir artistic director. The subjects had a mean of 1.7 ± 1.1 years in the Boychoir (0-5 years). None reported history of vocal issues or voice problems in the past; seven (25%) subjects had vocal fold lesions seen at one or more frequencies; 24 (85%) subjects had a posterior gap seen at one or more frequencies. Two subjects (7%) had a posterior gap at one frequency, C3 and G3, respectively. Five subjects (18%) had a posterior gap at two frequencies, seven subjects (25%) at three frequencies, and 10 subjects (36%) in all four frequencies.Conclusions: Our study aimed to describe the laryngeal examination of dedicated Boychoir singers prior to undergoing pubertal development and vocal maturation. In elite pediatric singers we found that vocal nodules are common (25%) and are not correlated with vocal symptoms. These findings may suggest that asymptomatic lesions may be more prevalent than previously thought. In these individuals, posterior glottic gap is common and can be considered a normal glottal configuration.Level Of Evidence: 4 Laryngoscope, 131:592-597, 2021. [ABSTRACT FROM AUTHOR]

Objectives: The hypoglossal nerve stimulator (HNS) is an effective treatment for obstructive sleep apnea (OSA) in a relatively healthy subset of the population. Our aim was to determine the efficacy of HNS in a veteran population with a high incidence of chronic disease and mental health disorders. Our secondary aim was to compare subjective outcomes and adherence between veterans with and without mental health disorders.Methods: We included all patients who underwent HNS at our institution to date. Veterans were divided into two groups based on whether or not they carried a diagnosis of anxiety, depression, and/or post-traumatic stress disorder. Demographics, comorbidities, previous OSA treatments, adverse events, and adherence to therapy were recorded. Baseline and treatment outcome data were collected and analyzed including polysomnographic parameters, Epworth sleepiness scale score (ESS), and body mass index.Results: Thirty-one patients were identified: 93.5% male, median age = 63.0 years. Median apnea hypopnea index (AHI) decreased from 30.0 to 3.0 events/hour (P < .001) and median ESS dropped from 11.0 to 6.5 (P < .001). There was no difference between groups with regard to change in AHI or ESS (P = .31 and .61). Twenty-six (89.7%) patients achieved surgical success (decrease in AHI > 50% and AHI < 20 events/hour) and 21 (72.4%) had AHI < 5 events/hour. The mean device usage was 5.4 hours/night which was not significantly different between groups (P = .55).Conclusion: Our cohort exhibited similar declines in AHI and ESS compared to published studies with adequate adherence to HNS. There were no significant differences in ESS or adherence to therapy between veterans with and without mental health disorders.Level Of Evidence: 4 Laryngoscope, 130:2275-2280, 2020.

Objectives/hypothesis: Characterization of leadership within otolaryngology is key to evaluating trends and promoting program advancement. This study evaluates representation of women in otolaryngology holding residency and fellowship directorships, or chair positions, comparing sex differences in academic rank, years in practice, and scholarly activity.Study Design: Cross sectional analysis.Methods: A comprehensive list of otolaryngology residency and fellowship directors from Accreditation Council for Graduate Medical Education-accredited programs in 2017 to 2018 was compiled. Academic rank and years in practice were determined from departmental websites, with online search tools used as secondary resources. The h-index was utilized as a measure of research productivity. Regression analysis was performed to analyze these variables.Results: Among the 306 directorships, women held 57 (18.6%) of these positions, 27 (26.5%) residency and 30 (14.7%) fellowship directorships. Of the 99 chair positions, five (5.1%) were held by women. The majority (53.6%) of male directors were full professors, whereas only 26.3% of females were full professors (P = .04). Mean years in practice for female directors (13.9 ± 6.8) was less than that of male directors (20.3 ± 9.4, P < .0001). Similarly, mean h-index for female directors (11 ± 7.2) was lower than for males (17.5 ± 12.5, P = .0001). After controlling for academic rank and years of practice in a multivariable regression, the h-index remained lower for women than for men (P = .03).Conclusions: Women are disproportionately underrepresented in positions of residency and fellowship directorships, and chair positions, consistent with other specialties. Women in leadership had lower academic ranks, fewer years of practice, and lower h-indices than their male counterparts. This may represent a shift in academic otolaryngology as female otolaryngologists seek early involvement in leadership.Level Of Evidence: 4 Laryngoscope, 130:1664-1669, 2020. [ABSTRACT FROM AUTHOR]
