Otolaryngology-head and neck surgery resident and medical school characteristics: Current paradigm amidst changing application criteria.

PURPOSE: To determine the characteristics of current US Otolaryngology-Head and Neck Surgery (Oto-HNS) residents and their medical school. METHODS: Data were manually collected between Dec 2022 and Jan 2023 for 1649 residents attending 163 US-based ACGME accredited Oto-HNS residency programs, reflecting the 2018-2022 cohort. All data were collected from publicly available sources including residency and medical school program websites, web of science, and professional networking sites (ex: LinkedIn, Doximity). Data were analyzed to determine the "feeder" schools which contributed the greatest number and percent of residents. Using univariable linear regression models, we characterized factors which were associated with feeder school status. RESULTS: Of 1649 residents analyzed, 364 (22 %) matched to their home program and 918 (56 %) stayed in the region of their medical school. The median [IQR] number of published papers and abstracts was 5 [3, 9] with an h-index of 2 [1,4]. Factors associated with producing a greater percent of Oto-HNS residents include presence of an interest group, presence of a home program, USNWR research rank of the medical school, Doximity reputation rank of the home residency program, average pre-residency h-index of the school's graduates, and total NIH research funding (each p < 0.001). CONCLUSIONS: In the changing landscape of residency applications after the USMLE Step 1 exam's transition in January 2022 to pass/fail scoring, it is important to objectively characterize current Oto-HNS residents. Findings from this study will inform prospective residents and residency programs seeking to improve access to Oto-HNS. Future small-scale studies may help further identify driving factors within medical school curricula.

Interdisciplinary assessment of tracheostomy care knowledge: An opportunity for quality improvement.

PURPOSE: A 2013 AAOHNS consensus statement called for reduced variation in tracheostomy care. Multidisciplinary approaches and standardized protocols have been shown to improve tracheostomy outcomes. This study aims to identify inconsistencies in knowledge in order to design standardized education targeting these areas to improve quality of care. MATERIALS AND METHODS: An online, multiple-choice tracheostomy care knowledge assessment was administered to nurses and respiratory therapists in ICUs, stepdown units, and regular nursing floors, as well as residents in otolaryngology, general surgery, and thoracic surgery. The survey was administered and data were recorded using the Select Survey online platform. RESULTS: 173 nurses, respiratory therapists, and residents participated in this study. Over 75 % of respondents identified correct answers to questions addressing basic tracheostomy care, such as suctioning and humidification. Significant variation was observed in identification and management of tracheostomy emergencies, and appropriate use of speaking valves. Only 47 % of all respondents identified all potential signs of tracheostomy tube displacement. Respiratory therapists with over 20 years of experience (p = 0.001), were more likely to answer correctly than those with less. Nurses were less likely than respiratory therapists to have received standardized tracheostomy education (p = 0.006) and were less likely than others to choose the appropriate scenario for speaking valve use (p = 0.042), highlighting the need for interdisciplinary education. CONCLUSIONS: An interdisciplinary assessment of tracheostomy care knowledge demonstrates variation, especially in identification and management of tracheostomy emergencies and appropriate use of speaking valves. Design of a standardized educational program targeting these areas is underway.

An institution-wide tracheostomy rounding team: Initial caregiver perceptions.

PURPOSE: To analyze and present the initial findings of provider perceptions regarding the impact of the implementation of a hospital-wide Tracheostomy Rounding Team (TRT) on the delivery of tracheostomy care at the Cleveland Clinic. MATERIALS AND METHODS: Based on prior literature, a novel multidisciplinary TRT was designed and implemented at the Cleveland Clinic in December of 2018. After the TRT began clinical care, a previously validated RedCap survey was administered anonymously to 358 caregivers to assess provider experience, comfort, and prior education regarding tracheostomy management. Survey results were collected, and descriptive statistics were applied. Answers were compared between providers who interacted with the TRT clinically and those who did not. RESULTS: 42.9% of providers who interacted with the TRT clinically reported that the TRT improved hands-on assistance with tracheostomy care, and 36.7% reported that the TRT improved the identification of safety concerns. Similarly, 34.7% reported that the TRT improved the overall quality of tracheostomy care at the Cleveland Clinic. Providers with active exposure to the TRT additionally reported statistically higher comfort with multiple topics surrounding tracheostomy care. CONCLUSIONS: The implementation of this team improved provider comfort in managing patients with tracheostomies both qualitatively and quantifiably. This intervention offered a perceived benefit to patient care at our institution. Further study of the impact of this team on quantitative patient outcomes is forthcoming.

Considerations and Management of a Laryngeal Fracture after Sneezing.

Non-traumatic laryngeal fracture is uncommon but should be suspected whenever patients present with dysphonia, odynophagia, dysphagia, neck crepitus, or hemoptysis following a sneeze or coughing episode. Physical examination coupled with computed tomography is essential for making the diagnosis. Management can vary depending on the severity of the case, but the general approach is similar to any trauma. In this report, we describe a non-traumatic laryngeal fracture that occurred following a forceful sneeze. The case was notable for the presence of pneumomediastinum, independent mobility of the thyroid ala, and operative intervention was pursued to repair the fracture.

Surgical management of recurrent Zenker's diverticulum: A multi-institutional cohort study.

OBJECTIVE: This study identifies how recurrent Zenker's diverticula are treated. METHODS: A retrospective chart review was performed from four tertiary referral academic voice and swallowing centers to identify individuals who underwent surgery for recurrent Zenker's diverticulum. Demographic data, surgical modalities for primary and revision surgery, symptoms pre and post revision and complications were recorded. RESULTS: 56 individuals met inclusion criteria. Primary surgery was open in 30.3% (n = 17) and endoscopic in 69.6% (n = 39). Revision surgery was performed via an open approach in 37.5% of cases (N = 21) and via an endoscopic approach in 62.5% of cases (N = 35). Revision surgical technique was based on pouch size, patient age and comorbidities, as well as patient and surgeon preference. There were no major complications and few minor complications. CONCLUSION: Zenker's diverticulum symptoms can recur regardless of primary treatment modality. Both endoscopic and open approaches can safely treat recurrent Zenker's diverticula.

Healthcare usage after uvulopalatopharyngoplasty - Impact of analgesic regimen.

OUTCOME OBJECTIVES: 1) Analyze differences in healthcare usage between subjects receiving different perioperative analgesic medications after uvulopalatopharyngoplasty (UPPP) surgery. 2) Comment on the impact of perioperative analgesic medication on length of hospital stay and complications after UPPP. METHODS: A retrospective cohort study of 120 UPPPs conducted by a single surgeon in the past 5years was conducted. Subjects were grouped based on perioperative pain medication regimen into three groups; narcotics alone (n=83), narcotics with gabapentin (n=27), or narcotics with ketorolac tromethamine (n=10). The primary outcome variable was total number of clinic/emergency room and/or telephone encounters related to post-UPPP pain. Secondary outcomes included length of post-operative hospital stay, number of telephone and/or clinical encounters in which the patient complained specifically of pain or requested a refill for analgesics, and post-operative complications. RESULTS: No significant difference was found between the three analgesic regimens in post-operative hospital stay length (p=0.28, median stay 23.5h), number of clinic or telephone encounters related to pain (p=0.26, mean value 0.71 encounters), or post-operative complication rate (p=0.82, 5.9% complication rate). CONCLUSION: This study shows no significant difference in post-operative healthcare usage between patients with peri-operative analgesic regimens including narcotics alone, gabapentin with narcotics, or ketorolac with narcotics. Post-operative complication rate and length of stay did not differ between groups. These data suggest that these three medication regimens have similar impact on post-operative course for UPPP patients. Therefore, the most affordable or simplest options have equivalent effects on post-operative healthcare usage.

Treatment of laryngopharyngeal reflux using a sleep positioning device: A prospective cohort study.

OBJECTIVE: Laryngopharyngeal reflux (LPR) symptoms are often resistant to management and cause significant quality of life impairment to patients with this disease. This study assesses the utility of a sleep-positioning device (SPD) in treating LPR. DESIGN: Single center prospective cohort study. SETTING: Tertiary medical center PARTICIPANTS: 27 adult patients with diagnosed laryngopharyngeal reflux. INTERVENTION: An SPD consisting of a two-component wedge-shaped base pillow and a lateral positioning body pillow (Medcline, Amenity Health Inc.) was given to patients with a diagnosis of LPR. Subjects slept using the device for at least 6h per night for 28 consecutive nights. MAIN OUTCOMES: Primary outcomes were Nocturnal Gastroesophageal Reflux Symptom Severity and Impact Questionnaire (N-GSSIQ) and the Reflux Symptoms Index (RSI) survey instrument. Each was collected at baseline, after 14, and after 28days of SPD use. RESULTS: 27 patients (19 female and 8 male; age 57.1±12.8, BMI 29.0±8.1) were recruited. At baseline mean N-GSSIQ was 50.1±22.4 and mean RSI of 29.6±7.7. Repeated measure analysis showed that subjects' total N-GSSIQ scores decreased by an average of 19.1 (p=0.0004) points by two weeks and 26.5 points by 4weeks (p<0.0001). RSI decreased an average of 5.3 points by 2weeks (p=0.0425) and an average of 14.0 points by 4weeks (p<0.0001). CONCLUSIONS: In patients with LPR, SPD treatment significantly improves self-reported symptoms of nocturnal reflux as well as symptoms specific to LPR. These results support the therapeutic efficacy of a SPD for patients with LPR.

Quantitative and qualitative perceptions of the 2011 residency duty hour restrictions: a multicenter, multispecialty cross-sectional study.

BACKGROUND: July 2011 saw the implementation of the newest duty hour restrictions, further limiting the working hours of first year residents and necessitating a variety of adaptations on the part of residency programs. The present study sought to characterize the perceived impact of these restrictions on residency program personnel using a multi-specialty and multi-site approach. METHODS: We developed and administered a survey to internal medicine and general surgery residency programs at three academic medical centers within an urban region. The survey combined quantitative and qualitative components to gain a broader understanding of the impact of the newest regulations. Quantitative responses were compared between Internal Medicine and General Surgery programs with Student t-tests. Other comparisons were performed using ANOVA or Kruskal-Wallis testing as appropriate. For all comparisons, the threshold for significance was set at 0.01. Two independent reviewers coded all qualitative data and assigned one or more themes based on content. Descriptive statistics were calculated and the diversity of themes identified. No between-group comparisons were conducted with the qualitative data. RESULTS: We found significant differences in the overall perceptions of duty hour restrictions across specialty (internal medicine more positive than general surgery) and across position (first year residents more positive than senior residents and faculty). Notably, individuals who trained at osteopathic medical schools reported significantly more negative views of the duty hour restrictions than those who had trained at allopathic or international medical schools, suggesting an influence of undergraduate medical training. The complementary qualitative data offered insights into the perceived strengths and weaknesses of the duty hour restrictions, as well as actionable suggestions that could help to improve residency program function. CONCLUSION: This study characterizes responses to the new duty hour restrictions from a variety of perspectives. Our findings show that individual (type of undergraduate medical education, role in graduate medical education) and program-wide (e.g., specialty) factors contribute to participant satisfaction with DHR. This research highlights the value of a mixed methods approach in the study of duty hour restrictions, with our qualitative arm yielding rich data that complemented and expanded upon the insights derived from the quantitative data.

Defining the fat compartments in the neck: a cadaver study.

BACKGROUND: Cervicoplasty is an important component of aesthetic facial and neck surgery, but the fat content in this area has not been described. OBJECTIVES: The authors identify anatomic compartments of fat in the neck (specifically the areas relevant to surgical management), quantify the fat in each compartment, and describe the relationships between each compartment and the submandibular glands. METHODS: The skin was removed from 10 fresh cadaver heads. Each compartment of fat was weighed, along with the submandibular gland. Supraplatysmal fat was found between the skin and the platysma muscle, and it was compartmentalized into suprahyoid and infrahyoid fat. Subplatysmal fat was found deep to the platysma and between the medial edges of the anterior digastric in the midline; this fat also fell into suprahyoid and infrahyoid compartments. The "very deep" fat was deep to the anterior digastric muscles and submandibular gland, and adherent to the strap muscles. RESULTS: On average, supraplatysmal fat represented 44.7% of the fat in the neck, the subplatysmal fat represented 30.7%, and the submandibular gland represented 24.5%. The very deep fat was scant, representing less than 1% of the fat in the neck. CONCLUSIONS: This anatomic study provides a comprehensive review of fat in the neck, and the results should serve as an additional guide as surgeons approach this challenging area in surgical rejuvenation.

Temporomandibular Dysfunction and Voice-Related Quality of Life Impairment.

OBJECTIVE: Muscle tension in the head and neck may co-occur with temporomandibular dysfunction (TMD) possibly leading to voice change. Several studies have reported a correlation between TMD and dysphonia. However, literature on TMD and voice-related quality of life (QOL) is scant. This study aimed to investigate the relationship between TMD and self-perceived voice-related QOL impairment. METHODS: Patients from TMD clinic were prospectively surveyed on voice-related quality of life using the Voice Handicap Index (VHI) questionnaire. Patients were queried using paper and pen upon initial evaluation in dentistry clinic for temporomandibular disorders by a single dentist or dental assistant in the otolaryngology department. RESULTS: A total of 53 patients completed the VHI. 80% of patients presenting to TMD clinic had VHI scores above zero, but most had minimal to mild impairment. Forty-two patients had scores between 1 and 86, (average 10.98); 11 patients had a score of zero (20.75%). Total average score: 8.70, range: 0-86, median: 4. Functional average score: 3.13, range: 0-29, median: 1. Physical average score: 3.58. range: 0-25, median: 2. Emotional average score: 1.98, range: 0-32, median: 0; these averages did not differ from historical controls. CONCLUSION: The majority of patients presenting to TMD clinic also presented with some level of voice-related QOL impairment, although minimal and consistent with historical VHI controls. Data indicates that TMD disease may be primarily defined as functionally and physically uncomfortable. Incorporation of interdisciplinary care, with laryngology, speech pathology, physical therapy, counseling, and pain management may be warranted. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:315-317, 2024.

The Role of Bilateral Superior Laryngeal Nerve Block in Managing Refractory Chronic Cough.

OBJECTIVE(S): The aim was to investigate the utilization and efficacy of bilateral superior laryngeal nerve block in patients with refractory chronic cough. METHODS: A retrospective chart review of 164 patients with refractory chronic cough who underwent bilateral SLN block at a single institution between November 2018 and September 2022 was performed. Demographics, comorbidities, and patient-reported outcomes including pre- and postinjection Leicester Cough Questionnaire (LCQ) scores were collected and analyzed. RESULTS: The cohort underwent an average of 2.97 bilateral injections (range 1-22), containing either corticosteroid and local anesthetic or corticosteroid alone. Notably, 116 of 164 of patients reported an average of 67.3% reduction in their symptoms, with the treatment effect lasting 7.60 weeks on average. The average pre- and postinjection LCQ scores were 9.70 and 13.82, respectively. A lower LCQ score represents a greater impairment of health status due to cough, and the minimum important change is 1.3 points between questionnaires. The average improvement on LCQ following bilateral SLN block was 4.11 points for this cohort. CONCLUSION: The use of in-office bilateral SLN block is an effective treatment that can be used alone or in conjunction with oral medications for the treatment of refractory chronic cough. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:1773-1777, 2024.

The Application of Superior Laryngeal Nerve Block for Non-Cough Laryngeal Hypersensitivity.

OBJECTIVE(S): To investigate the effect of superior laryngeal nerve (SLN) block in patients with non-cough complaints relating to laryngeal who have failed conventional medical therapy. METHODS: Retrospective chart review of 46 patients who underwent SLN block for non-cough indications between July 2019 and March 2022 was performed. Demographics, comorbidities, and patient-reported outcomes were collected. The primary diagnoses for this group included: odynophagia, throat pain, cervicalgia, muscle tension dysphonia, globus sensation, hyoid bone syndrome, and Eagle syndrome. RESULTS: The cohort underwent an average of 1.24 bilateral injections (range 0-7) and 0.87 unilateral injections (range 0-4). About 35 of 46 patients reported an average of 51.0% improvement in their symptoms, with the treatment effect lasting 7.60 weeks on average. On subgroup analysis, the patients with spasmodic dysphonia, odynophagia, and hyoid bone syndrome had the best percent improvement on average (75%-77.5%). Patients with globus sensation had the lowest percent improvement on average in response to this therapy, reporting only about 25%. Five patients experienced a mild adverse reaction immediately following injection which resolved spontaneously. CONCLUSION: The use of in-office SLN block for non-cough disorders involving the larynx requires further study with larger sample sizes to better delineate the efficacy of these applications. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:1765-1768, 2024.

Scoping Review of Surgical Rehabilitation of Post Intubation Phonatory Insufficiency.

OBJECTIVES: Post intubation phonatory insufficiency (PIPI) or posterior glottic diastasis describes posterior glottic insufficiency (PGI) caused by prolonged intubation causing medial arytenoid ulceration, mucosal scarring, and incomplete cricoarytenoid joint adduction. The purpose of this review is to showcase diagnostic findings, surgical rehabilitation, and gaps in our treatment algorithm of PIPI. DATA SOURCES: Embase, PubMed, Scopus, Web of Science. REVIEW METHODS: Two independent reviewers completed a systematic search of the literature studying PIPI. Reported intubation history, laryngeal defect, clinical symptoms, surgical intervention, and outcomes were gathered from included studies. RESULTS: Nine studies met our inclusion criteria for full review, (45 patients) all of which were case reports/series. All patients had posterior glottic defects, most commonly loss of medial arytenoid tissue, causing varying degrees of PGI. Eleven patients had vocal fold (VF) immobility or hypomobility. Treatment interventions were observation (1), speech therapy (2), VF or posterior glottic injection augmentation (15), medialization laryngoplasty (4), arytenoid repositioning (6), endoscopic (19) or open (3) posterior cricoid reduction, local mucosal rotation flap (11), or free mucosal graft (2) to fill the glottic defect. Observation, voice therapy, and augmentation or type 1 laryngoplasty failed to improve symptoms. Other surgical techniques improved symptoms with varying outcomes. CONCLUSION: PIPI is a difficult injury to diagnosis and treat. Conservative measures and augmentation/laryngoplasty often fail to fix the PGI. Our review supports symptom improvement with reconstruction of the posterior glottic defect with cricoid reduction or mucosal grafts. Future investigation is needed to better define the diagnosis and successful treatment algorithm. Laryngoscope, 134:2048-2058, 2024.

Surgical Management of Airway Stenosis During Pregnancy: A Scoping Review.

OBJECTIVE: There are several options for surgical management of subglottic stenosis, including endoscopic and open procedures. However, treatment algorithms, outcomes, and anesthetic management of subglottic stenosis during pregnancy are not well described. DATA SOURCES: MEDLINE, EMBASE, and the Cochrane databases. REVIEW METHODS: A scoping review of management of subglottic stenosis during pregnancy was performed, and then reported in compliance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Inclusion criteria consisted of those with subglottic or tracheal stenosis aged greater than 18 years, those in whom management was performed during pregnancy, and those who reported delivery related outcomes. RESULTS: After systematic review and detailed search of 330 identified articles, 15 articles met inclusion criteria and were included in the final analysis. All studies were case reports or case series (level 4 evidence). This study identified 27 patients. The median age was 29 and the median gestational age at intervention was 28 weeks. Left lateral positioning and fetal heart rate monitoring were used in nearly every case. The most common intervention performed was endoscopic balloon dilation. In many cases, jet ventilation or transnasal humidified rapid insufflation ventilatory exchange was satisfactory for maintenance of the airway. Three women ultimately required tracheostomy prior to labor and delivery. There was no fetal death or complications reported in these studies, and all but one woman proceeded to deliver at term. CONCLUSION: Endoscopic balloon dilation during pregnancy is safe and effective, resulting in optimized respiratory outcomes for the mother and safe delivery of the fetus. The third trimester appears to be safe for airway intervention. Laryngoscope, 134:1014-1022, 2024.

Impact of Procedural Variation in Endoscopic Dilation for Idiopathic Subglottic Stenosis.

OBJECTIVES: A small number of Idiopathic subglottic stenosis (iSGS) patients are treated at institutions across the country. Divergence in operative techniques for endoscopic dilation (ED) of iSGS has been anecdotally recognized but not formally characterized. Additionally, the relationship between procedural variation and clinical outcome has not been studied. METHODS: Secondary analysis of the NoAAC iSGS1000 cohort investigated variation in procedural techniques and treatment outcomes in patients treated with ED across high-enrolling treatment centers (enrolled >10 patients in PR-02 trial). RESULTS: Thirteen NoAAC centers each enrolled >10 patients treated with ED for a total of 281 subjects. There was significant variation in procedural details and rate of recurrence among institutions. Hierarchal cluster analysis revealed significant heterogeneity among institutions and clusters in all procedural variables. However, analysis demonstrated a transient delay in disease recurrence in cluster 2 which disappeared with longer longitudinal follow-up. Patient-reported outcome and peak expiratory flow data supported the potential benefit of the technical variation in Cluster 2. Distinct to cluster 2, however, was routine use of adjuvant triple medical therapy (proton pump inhibitor (PPI), antibacterial agent, and steroid inhaler). CONCLUSIONS: Both outcome and procedural technique vary among centers employing ED to treat iSGS. A transient delay in recurrence was observed among centers that routinely prescribed adjuvant medical therapy (antibiotic, inhaled corticosteroid, and PPI) to iSGS patients after endoscopic dilation, which was further supported by patient-reported data and peak expiratory flow data. Prospective studies are needed to understand the effects of adjuvant medical therapy on recurrence after endoscopic dilation. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:3260-3266, 2024.

Laser Versus Cold Steel for Endoscopic Management of Subglottic Stenosis.

OBJECTIVE: Endoscopic management of subglottic stenosis (SGS) includes a wide range of techniques. This 17-year review compares treatment outcomes between carbon dioxide (CO2) laser and cold steel. STUDY DESIGN: Retrospective chart review. SETTING: Single tertiary care center. METHODS: A chart review was performed for all patients undergoing endoscopic treatment of SGS at Cleveland Clinic between July 12, 2000 and September 1, 2017. Data collected included demographics, stenosis etiology, stenosis severity, comorbidities, treatment modality, and airway procedure history. The primary endpoint was repeated treatment-free survival (RTFS) within 2 years using a Kaplan-Meier analysis and Cox proportional hazard model. RESULTS: A total of 139 patients (median [interquartile range] aged 48.7 [37.8, 57.0] years; 83.4% female) were included in the analysis, with etiologies including idiopathic (56.8%), granulomatosis with polyangiitis (25.2%), and intubation (16.5%). All patients underwent either cold steel (107 patients) or CO2 laser (32 patients) lysis of stenosis with concurrent dilation. RTFS within 2 years was 50.2% for CO2 laser and 31.9% for cold steel (hazard ratio [HR] and 95% confidence interval [CI]: 1.69, 0.96-2.97, P = .07). In patients with no prior airway procedures, there was no difference in RTFS between laser and cold knife (P = .41). However, in patients with prior airway procedures, RTFS was significantly greater in the laser group, even after adjusting for age, smoking history, and stenosis etiology (50.0% vs 16.8%, adjusted HR and CI: 2.82, 1.14-6.98, P = .025). CONCLUSION: Endoscopic lysis of SGS with CO2 laser should be considered in revision cases.

Historical Review and Modern Case of Spontaneous Laryngeal Abscess.

OBJECTIVE: Laryngeal abscesses are rare in the modern antibiotic era. Historically, they were associated with systemic infections including typhoid fever, measles, gonorrhea, syphilis, and tuberculosis. More recent authors have described cases resulting from iatrogenic injury and immunosuppression. This report presents a novel case of laryngeal abscess in the setting of uncontrolled diabetes and a detailed review of modern, reported cases of spontaneous laryngeal abscess. METHODS: Report of a single case. Also, PubMed was queried for cases of laryngeal abscess since 1985. CASE REPORT: A 58-year-old male with poorly controlled diabetes presented with odynophagia, dysphagia, and dyspnea. He had biphasic stridor, and flexible laryngoscopy showed reduced mobility of bilateral vocal folds and narrowed glottic airway. He was taken urgently for awake tracheostomy and microdirect laryngoscopy. Laryngoscopy demonstrated fullness and fluctuance of the right hemilarynx. The abscess cavity was entered endoscopically via paraglottic incision extending into the subglottis. The patient was treated with an 8-week course of ampicillin-sulbactam with resolution of infection. RESULTS: Seven additional cases of spontaneous laryngeal abscesses published after 1985 were identified. In total, 6 of 8 had some form of immunodeficiency (75%). The most common presenting symptoms were dysphonia (8/8, 100%), odynophagia (5/8, 62.5%), and dyspnea/stridor (4/8, 50%). All cases were treated with surgical incision and drainage. CONCLUSIONS: Laryngeal abscesses are rare in the era of modern antibiotics. This review confirms that the majority of recent episodes occurred in the setting of immunodeficiency and are caused by non-tubercular bacteria. These infections are commonly associated with impaired vocal fold mobility which may contribute to dyspnea, stridor, and airway compromise. Surgical intervention is necessary for treatment and culture-directed antimicrobial therapy. Poorly controlled diabetes is a newly described context for development of spontaneous laryngeal abscess.

Readmission Rates Following Major Head and Neck Surgery With Concurrent Tracheostomy.

OBJECTIVES: To determine the influence of major head and neck procedures on readmission and complication rates following tracheostomy. METHODS: A retrospective cohort study using the 2005 to 2017 National Surgical Quality Improvement Program (NSQIP) database. Current Procedural Terminology codes were used to identify tracheostomy patients and to define the underlying head and neck procedure. Patients under the age of 18 and with unknown pre-operative variables were excluded. Univariate and multivariable analyses were performed. RESULTS: A total of 3240 tracheostomy patients undergoing major head and neck surgery were identified in NSQIP. The 30-day mortality rate was 104 (3.2%) and 258 (9.0%) patients were readmitted. 637 (19.7%) patients had an unplanned return to the operating room. There were 1606 (49.6%) non-tracheostomy specific complications, which included 850 (26.2%) medical and 1142 (35.2%) surgical complications. On multivariable analysis, we found that the underlying procedures did not impact the risk of readmission (P > .05 for all). The underlying procedure was also not associated with unplanned return to the operating room except for thyroidectomies, which had a lower risk than free tissue graft reconstruction (OR = 0.53 (95%CI 0.31, 0.88), P = .018). CONCLUSION: While almost 1 in every 2 patients had a complication following major head and neck surgery that included creation of a tracheostomy, the rate of readmission is comparatively low and is not associated with the underlying procedure. These findings should reassure head and neck surgeons that properly managed tracheostomies do not constitute a disproportionate risk of readmission.

Reassessing the Role of Phonomicrosurgery and Smoking Status in the Management of Reinke's Edema.

OBJECTIVES: To elucidate recurrence patterns of Reinke's edema (RE) following phonomicrosurgery and compare current and former smokers' outcomes. METHODS: A retrospective chart review was performed for patients who underwent microflap excision for RE at our institution since 2008. Patient data were collected, including demographics, smoking history, and operative and voice outcomes during the available follow-up period. Descriptive statistics, student's t-tests, Chi-squared analyses, and Fischer's exact tests were used for the appropriate between-group comparisons utilizing JMP statistical software. RESULTS: Patients who quit smoking on the day of surgery or continued to smoke postoperatively were included in our group of current smokers (n = 56). Patients who quit smoking within the month of surgery or longer were included in our group of former smokers (n = 22). There was no significant difference in postoperative voice outcomes between groups. Eight patients in the entire cohort experienced recurrence during the available follow-up period. Fischer's exact test revealed no statistically significant association between smoking status and recurrence (two-tailed p > 0.05). The mean time to recurrence for current smokers who did recur was 69 and 54 months for former smokers. CONCLUSION: We report low overall recurrence rates after microflap excision of RE lesions compared with historical data, without any significant difference in recurrence or voice outcomes when comparing current and former smokers. Further prospective trials with larger sample sizes are warranted to guide the surgical management of RE patients and the implications of smoking status. LEVEL OF EVIDENCE: 3 Laryngoscope, 2023.

Mapping Genetic Susceptibility to Stenosis in the Proximal Airway.

OBJECTIVES: Recent translational scientific efforts in subglottic stenosis (SGS) support a disease model where epithelial alterations facilitate microbiome displacement, dysregulated immune activation, and localized fibrosis. Yet despite recent advances, the genetic basis of SGS remains poorly understood. We sought to identify candidate risk genes associated with an SGS phenotype, investigate their biological function, and identify the cell types enriched for their expression. METHODS: The Online Mendelian Inheritance in Man (OMIM) database was queried for single gene variants associated with an SGS phenotype. The functional intersections and molecular roles of the identified genes were explored using pathway enrichment analysis (PEA) computational methods. Cellular localization of the candidate risk genes was measured via transcriptional quantification in an established single cell RNA sequencing (scRNA-seq) atlas of the proximal airway. RESULTS: Twenty genes associated with SGS phenotype were identified. PEA resulted in 24 significantly enriched terms including "cellular response to TGF-ß," "epithelial-to-mesenchymal transition," and "adherens junctions." Mapping the 20 candidate risk genes to the scRNA-seq atlas found 3 (15%) genes were enriched in epithelial cells, 3 (15%) in fibroblasts, and 3 (15%) in endothelial cells. 11 (55%) genes were expressed ubiquitously among tissue types. Interestingly, immune cells were not significantly enriched for candidate risk genes. CONCLUSION: We identify and provide biologic context for 20 genes associated with fibrotic disease of the proximal airway and form the foundation for future detailed genetic study.
