RESUMO
INTRODUCTION: To gain an understanding of the changing faces of leadership in surgery, we examined trends in the demographics, additional degrees pursued, and scientific publication characteristics of the past presidents of three major surgery organizations. METHODS: We queried the BoardCertifiedDocs and Web of Science databases for the demographics, as well as the quantity and quality of publications, of the past presidents of the Association for Academic Surgery, Society of University Surgeons, and American College of Surgeons from 1970 to 2020. Data were analyzed by decade to identify any trends. RESULTS: We identified a total of 140 presidents from the organizations. The proportion of female presidents significantly increased from the 1990s to the 2010s (10% versus 33%, P < 0.05). The percentage of non-White presidents increased from the 1970s to the 2010s (3.33% versus 21.2%, P = 0.024). The percentage of presidents with additional degrees also increased from the 1970s to the 2010s (10.0% versus 48.8%, P = 0.039). During this same time period, the most common area of expertise of presidents shifted from cardiothoracic surgery to surgical oncology. The ratio of presidents' postinduction to preinduction publications was significantly increased among all three organizations in the 2010s compared to the 1970s (P < 0.05). Co-cluster analysis revealed a research topic change from the 1970s to the 2010s. CONCLUSIONS: The faces of surgical leadership have changed in terms of gender equality, racial diversity, surgical subspecialty, and additional degrees held. Such a transformation mirrors evolving diversity, equity, and inclusion initiatives, and it further highlights the adaptability of surgical leadership to the ever-changing landscape of surgery.

Most terpene synthase reactions follow Markovnikov rules for formation of high-energy carbenium ion intermediates. However, there are notable exceptions. For example, pentalenene synthase (PS) undergoes an initial anti-Markovnikov cyclization reaction followed by a 1,2-hydride shift to form an intermediate humulyl cation with positive charge on the secondary carbon C9 atom of the farnesyl diphosphate substrate. The mechanism by which these enzymes stabilize and guide the regioselectivity of secondary carbocations has not heretofore been elucidated. In an effort to better understand these reactions, we grew crystals of apo-PS, soaked them with the nonreactive substrate analogue 12,13-difluorofarnesyl diphosphate, and determined the X-ray structure of the resulting complex at 2.2 Å resolution. The most striking feature of the active site structure is that C9 is perfectly positioned to make a C-H···π interaction with the side chain benzene ring of residue F76; this would enhance hyperconjugation to stabilize a developing cation at C10 and thus support the anti-Markovnikov regioselectivity of the cyclization. The benzene ring is also positioned to catalyze the migration of H to C10 and stabilize a C9 carbocation. On the opposite face of C9, further cation stabilization is possible via interactions with the main chain carbonyl of I177 and the neighboring intramolecular C6âC7 bond. Mutagenesis experiments also support a role for residue 76 in these interactions, but most interesting is the F76W mutant, whose crystal structure clearly shows C9 and C10 centered above the fused benzene and pyrrole rings of the indole side chain, respectively, such that a carbocation at either position could be stabilized in this complex, and two anti-Markovnikov products, pentalenene and humulene, are formed. Finally, we show that there is a rough correlation (although not absolute) of an aromatic side chain (F or Y) at position 76 in related terpene synthases from Streptomyces that catalyze similar anti-Markovnikov addition reactions.

OBJECTIVE: To compare patterns of obstruction in infants and toddlers with obstructive sleep apnea (OSA) by analyzing drug-induced sleep endoscopy (DISE) examinations. STUDY DESIGN: Retrospective chart review. SETTING: An academic tertiary care pediatric hospital at a single institution. METHODS: Children aged ≤3 years who underwent DISE with propofol titration from 2020 to 2022 were included in the study. Data extracted included age, body mass index, comorbidities, and polysomnography parameters. The sites of anatomic obstruction during DISE were recorded using a validated 10-site scoring system. RESULTS: A total of 86 children underwent DISE, including 15 infants (<1 year) and 71 toddlers (>1≤3 years). Sixty-two percent were male and 37% were female. The mean age of the infant group was 9.6 months (95% confidence interval [CI]: 7.92, 11.28 months), and the mean age of the toddler group was 2.3 years (95% CI: 2.06, 2.50 years). The mean total number of sites of obstruction was not significantly different between infants (N = 2.5) and toddlers (N = 3.2, P = .086). The most common subsite of significant obstruction in both infants and toddlers was the aryepiglottic folds (46.7% and 36.8%, respectively; P = .578). The sites of obstruction and frequency of their occurrence were not significantly different between the 2 groups. CONCLUSION: Multisite airway obstruction is common among children with OSA, especially at the epiglottis, aryepiglottic folds, and tongue base. There is no difference in sites of obstruction and their frequency between toddlers and infants.

OBJECTIVE: To describe the prevalence of routine white noise exposure in children who undergo sound field audiometry. METHODS: A retrospective cohort study was conducted at a pediatric otolaryngology clinic affiliated with an academic tertiary care hospital. The medical records of children who underwent sound field audiometry were reviewed and data was collected regarding demographics and audiogram results. The group was divided into two cohorts based on routine exposure to white noise. Children exposed to white noise were tested with warble tones, while those not exposed were tested with narrow-band noise. RESULTS: 127 patients underwent sound field audiometry testing, of which 96 (75.6%) were reported by their parents to use white noise for sleep. The mean age at time of testing was 1.6 years (95% Confidence Interval [CI] 1.5-1.7). 104 (81.9%) children were able to respond to at least four of the sound field thresholds, and there was no significant difference between the children exposed to white noise and those who were not (P = 0.459). Mean pure tone average (PTA) was 26.2 dB (95% CI 25.2-27.2) and mean speech reception threshold (SRT) was 19.2 dB (95% CI 18.2-20.2). The sound field response rate, PTA, and SRT were similar between these two groups. CONCLUSIONS: The routine use of white noise therapy was extremely common in this pediatric population. The use of warble tones as the audiometric stimuli for children exposed to white noise resulted in similar testing success compared to the use of narrow-band noise in children not exposed to white noise.

OBJECTIVE: Previous research has indicated that sleep disordered breathing (SDB) can lead to a decreased quality of life in children and their families as compared to children who do not have SDB. The purpose of this study was to examine fatigue levels in parents who had young children who were impacted by sleep symptoms as determined by the OSA-18 scale. STUDY DESIGN: Survey. SETTING: Three pediatric otolaryngology clinics associated with a tertiary care children's hospital in Buffalo, NY. METHODS: Fatigue levels for parents of children with OSA-18 ≥ 60 were assessed using the Fatigue Severity Scale and the Chalder Fatigue Scale. Consecutive parents with at least one child between the ages of 1 and 10 were recruited. Parents scored their youngest child on the OSA-18 scale. RESULTS: Of the 261 respondents included, 37 parents had a child with an OSA-18 score ≥60. The majority, 211 (82.1%), of participants reported 2 caregivers in the household while 30 (11.7%) had 1 caregiver in the household. Parents of children with OSA-18 ≥60 had a significantly higher mean fatigue score, 16.5 ± 5.8, compared to their counterparts, 11.9 ± 5.2, on the Chalder Fatigue Scale (P < .001). Similar results were reported for the total score on the Fatigue Severity Scale, 34.7 ± 10.8 compared to 28.9 ± 12.0 (P = .004). CONCLUSION: Parents of children with OSA-18 score ≥60 are significantly more fatigued than parents of children with lower scores. Recognition of this is important for the health care community as it impacts not just the child with OSA but also their family.

INTRODUCTION: The diagnosis of ankyloglossia has increased significantly around the world over the last decade. Frenotomy is indicated in infants with ankyloglossia to improve breastfeeding, although there is little scientific evidence of its efficacy. The purpose of this study is to evaluate whether infants being referred for frenotomy had feeding issues prior to the procedure. METHODS: A retrospective chart review was undertaken for all infants under one year of age referred with ankyloglossia to a pediatric otolaryngology practice or a pediatric hospital between 2018 and 2020. Data included age at referral, gender, comorbidities, feeding issues, whether ankyloglossia was diagnosed, and whether frenotomy was done. Frequencies and non-parametric comparisons were calculated. RESULTS: Of the 646 consultations made for tongue tie, a diagnosis of ankyloglossia was made in 94.7% (N=612) of the patients based on clinical judgment. The most common feeding complaints were poor latch (57.1%, N=369) and painful latch (50.3%, N=325). Eighty one (12.5%) patients did not have a reported feeding difficulty. Most patients had an anterior tongue tie (85.8%, N=554), with some showing signs of restricted tongue movement (30.1%, N=184). Ankyloglossia was 4.03 times more likely to be diagnosed (p<.001) and frenotomy was 1.76 times more likely to be performed (p<.001) in the hospital setting compared to the clinic setting. Conclusion: Children under the age of one referred to otolaryngology for ankyloglossia were often diagnosed concordantly, although some lacked feeding issues that would indicate frenotomy. There are still knowledge gaps about infantile ankyloglossia in referring medical personnel.
RESUMO
Neonatal temporomandibular joint (TMJ) dislocation is rare. The purpose of this study is to describe a case of neonatal TMJ dysfunction and to review the literature on this topic. A six-day-old female was seen with both parents for evaluation of a dislocating jaw. Her mother had been breastfeeding successfully but noticed that there was a noticeable click every time the baby swallowed. Her jaw came out and down as she fed and then returned to the normal position. Over the last few days, her mother felt that only one side was involved as her jaw movement seemed asymmetrical. Her primary care physician had witnessed the click during the sucking reflex. The patient had a normal appearance and was otherwise healthy. The pediatric otolaryngologist observed deviation of the jaw toward the left with a palpable click upon mouth opening and spontaneous reduction with mouth closing. The symptoms resolved over the following month. The literature review showed few cases of TMJ dislocation in infants, most of which described fixed dislocation related to vomiting or crying. Due to the development of the TMJ in infancy characterized by joint laxity and a flat mandibular fossa, malfunctioning of the hinge joint mechanism could be expected to be more common early in life.
RESUMO
First branchial cleft cysts (FBCCs) arise due to an incomplete fusion of the cleft between the first and second branchial arches. Classically, they are found inferior to the pinna or along the external auditory canal. This report presents a unique case of a nine-month-old male with a first branchial cleft cyst completely within the pinna. The patient presented with a left auricular pit and pinna mass. Ultrasound revealed a homogeneous hypoechoic mass isolated to the pinna. Surgical resection revealed the cyst to be anterior to the inferior pinna cartilage, with the tract projecting anteriorly and inferiorly. Final pathology revealed a benign cyst lined by squamous epithelium and a rim of cartilage, confirming an FBCC. To our knowledge, FBCCs isolated to the pinna have not been previously reported. Awareness of the various presentations of this rare anomaly is essential for a prompt and accurate diagnosis.
RESUMO
INTRODUCTION: Otolaryngology continues to be dominated by men. As of 2019, only 18.4% of practicing otolaryngologists were women. The goal of this project was to introduce female students to otolaryngology as a career. METHODS: A Women in Otolaryngology event was held in September 2021. Participants included undergraduate and first- or second-year medical students from the University at Buffalo. During the event, students rotated through three skills stations working with female otolaryngology residents and attending physicians. Participants completed pre-and post-course surveys regarding their attitudes toward women in surgery and their perceptions of surgery and otolaryngology. RESULTS: A total of 17 students that completed both the pre- and post-course surveys were included. The mean age was 22.6 years (range 18-25 yr). Specifically, 13 (76.5%) of the participants were Caucasian, three (17.6%) were Asian, and one (5.9%) was Hispanic, and 15 (88.2%) were medical students. On the pretest, 10 (55.6%) participants strongly agreed or agreed that otolaryngology as a career is open to females, while on the posttest, 16 (88.9%) participants strongly agreed or agreed (p=0.002). Nine (50.0%) participants strongly agreed or agreed that they have access to resources to help make a decision if they want to pursue a career in otolaryngology before the event, while, after the event, 16 (88.9%) participants strongly agreed or agreed (p=0.007). Five (27.8%) participants strongly agreed or agreed prior to the event that they felt confident in their knowledge of what otolaryngology includes, while afterward 15 (83.3%) strongly agreed or agreed (p=0.002). CONCLUSION: The Women in Otolaryngology event increased participants' confidence in understanding otolaryngology, promoted understanding of resources available, and demonstrated the openness of the specialty to women.
RESUMO
BACKGROUND: Despite the "fourth threat" of administrative demands, department chairs of surgery are expected to continue being a "triple threat": productive in research, outstanding in teaching, and exemplary in practice. Increased demands despite limited time are the catch-22 of promotion. This study investigated the influence of becoming department chair on scholarly vigor. METHODS: The surgeons listed in the Society of Surgical Chairs Membership Directory website (n = 118) were included in this study. Three measures were compared during the pre- and post-promotion phases: (1) research productivity (annual publications); (2) authorship position in publications (first-authorship, co-authorship, and senior-authorship); and (3) scholarly impact (m-index and National Institute of Health funding). RESULTS: The median [interquartile range] number of publications per year increased post-promotion versus pre-promotion (7.64 [3.81-14.15] vs 4.12 [2.08-7.03], P < .0005). The median [interquartile range] number of first-authorship publications per year decreased (0.50 [0.00-1.00] vs 0.64 [0.32-1.22], P < .05), whereas the median [interquartile range] number of co-authorship (4.23 [1.98-9.70] vs 2.02 [1.02-3.95], P < .0005) and senior-authorship (1.87 [0.99-4.03] vs 1.00 [0.36-2.24], P < .0005) publications per year increased post-promotion. The mean ± standard deviation m-index increased post-promotion (1.67 ± 1.19 vs 1.23 ± 0.83, P < .01). The mean ± standard deviation annual National Institute of Health grant funding amount of 48% (n = 57) of the department chairs increased post-promotion ($365,000 ± $899,000 vs $98,000 ± $143,000 pre-promotion, P < .05). CONCLUSION: The fourth threat of administrative demands is not a threat to the triple threat. This study showed the department chairs' continued scholarly vigor after promotion, providing insight into their tenacity, resilience, and dedication.

BACKGROUND: Pediatric benign laryngeal tumors can often be treated as same-day surgeries. This study identified factors associated with prolonged hospital stay in children undergoing laryngeal surgery for benign tumors. METHODS: A retrospective analysis of records of pediatric patients who underwent laryngeal surgery with a post-op diagnosis of benign tumor was performed with the American College of Surgeons Pediatric National Surgery Quality Improvement Program (ACS-NSQIP-P) database (2014-2018). Clinical variables analyzed included comorbidities, total length of stay (LOS), readmission, and reoperation. RESULTS: 1775 patients were identified with a mean age at time of surgery of 8.95 years (95% CI 8.76-9.14). 966 (54.4%) were males and 809 (45.6%) were females. Mean LOS was 0.22 days (95% CI 0.12-0.32). Only 128 (7.3%) patients had a LOS of one day or more. Children with a variety of comorbidities, including premature birth, oxygen support, tracheostomy, developmental delay, and cardiac risk factors, had a significantly prolonged LOS (P < .001). Additionally, younger children were significantly more likely to stay overnight (ß = -0.041, P < .001). Twenty-three (1.3%) patients were readmitted, 2 (0.1%) were reintubated, and 13 (0.7%) underwent reoperation for related reasons. Despite the association of premature birth, ventilator dependence, oxygen support, tracheostomy, esophageal/GI disease, developmental delay, seizure, neuromuscular disorders, congenital malformations, and steroid use with LOS, only younger age and ventilator dependence were associated with readmission. CONCLUSION: This study suggests that laryngeal surgery for benign tumors is safe but recognizes that patients with comorbidities or young children may require a prolonged stay. Awareness of these implications may help guide management.
