Assessing Dysphagia in the Adult.

This article explores the landscape of dysphagia assessment in adults. Dysphagia, a complex condition affecting the lifespan and many health conditions, significantly compromises individuals' quality of life. Dysphagia is often underdiagnosed, emphasizing the need for comprehensive assessment methods to ensure timely and accurate intervention. It encompasses clinical history, physical examination, clinical and instrumental swallow evaluations. Procedures within each of these modalities are reviewed, highlighting strengths, limitations, and contribution toward a complete understanding of dysphagia, ultimately guiding effective intervention strategies for improved patient outcomes.

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.

Laryngological Symptomatology in Patients with Ehlers-Danlos Syndrome.

Laryngological manifestations of connective tissue diease with hypermobility such as ehlers-danlos syndrome (EDS) are not well defined in the literature. EDS is an inherited, hetrogeneous, connective tissue disorder characterized by joint hypermobility, skin extensibility, and joint dislocations. A case series of 9 patients is presented with varying laryngological complaints. Common comorbities include postural orthostatic tachycardia syndrome (POTS), fibromyalgia, irritable bowel syndrome (IBS), and gastroesophageal reflux disease (GERD)/laryngopharyngeal reflux disease (LPRD). Six patients were singers. Videostroboscopic parameters and treatment courses are described. It may be beneficial to view patients with EDS and laryngological complaints through a holistic lens as many may need interdisciplinary assessment and management. Laryngoscope, 134:894-896, 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.

Trends in Twitter Utilization Among Academic Otolaryngologists.

OBJECTIVE: To characterize Twitter utilization among academic otolaryngologists and evaluate the relationship between Twitter utilization and research productivity. METHODS: Data were collected manually from accredited US otolaryngology residency programs from July-November 2021. Program and faculty demographics were documented, including citations and H-index for faculty and Doximity reputation and US News and World Report ranking for programs. Twitter metrics were also recorded. Descriptive analyses and multivariable logistic regression models were used to identify predictors of Twitter utilization. RESULTS: Currently, 333 (16%) faculty and 70 (62%) programs have a Twitter account. Of these, 36 (11%) and 27 (39%), respectively, were created in 2020. The regression model indicates that for each 5 unit increase in H-index, the odds of having a Twitter account increase 22% (OR 1.22, 95% CI 1.10-1.34, p = 0.0009). The number of faculty with a Twitter account predicts the existence of program Twitter accounts (OR:1.49, 95% CI 1.01-2.19, p = 0.04). Finally, of the 323 faculty with a Twitter account and available Scopus profile, we found that the number of individuals with Twitter use out of proportion to their academic productivity was low (n = 8/323). CONCLUSION: The H-index is a significant predictor of faculty Twitter accounts, whereas the number of faculty with Twitter is a significant predictor of program Twitter utilization. Although Twitter utilization is increasing, especially during the coronavirus pandemic, the findings indicate that there is ample room for growth, particularly amongst faculty with strong academic portfolios.

A Medicare Physician Fee Schedule Analysis of Reimbursement Trends in Laryngology from 2000 to 2021.

OBJECTIVE: The purpose of this study is to characterize Medicare reimbursement trends for laryngology procedures over the last two decades. METHODS: This analysis used CMS' Physician Fee Schedule (PFS) Look-Up Tool to determine the reimbursement rate of 48 common laryngology procedures, which were divided into four groups based on their practice setting and clinical use: office-based, airway, voice disorders, and dysphagia. The PFS reports the physician service reimbursement for "facilities" and global reimbursement for "non-facilities". The annual reimbursement rate for each procedure was averaged across all localities and adjusted for inflation. The compound annual growth rate (CAGR) of each procedure's reimbursement was determined, and a weighted average of the CAGR for each group of procedures was calculated using each procedure's 2020 Medicare Part B utilization. RESULTS: Reimbursement for laryngology procedure (CPT) codes has declined over the last two decades. In facilities, the weighted average CAGR for office-based procedures was -2.0%, for airway procedures was -2.2%, for voice disorders procedures was -1.4%, and for dysphagia procedures was -1.7%. In non-facilities, the weighted average CAGR for office-based procedures was -0.9%. The procedures in the other procedure groups did not have a corresponding non-facility reimbursement rate. CONCLUSION: Like other otolaryngology subspecialties, inflation-adjusted reimbursements for common laryngology procedures have decreased substantially over the past two decades. Because of the large number of physician participants and patient enrollees in the Medicare programs, increased awareness and further research into the implications of these trends on patient care is necessary to ensure quality in the delivery of laryngology care.

Current Practices in Voice Data Collection and Limitations to Voice AI Research: A National Survey.

INTRODUCTION: Accuracy and validity of voice AI algorithms rely on substantial quality voice data. Although commensurable amounts of voice data are captured daily in voice centers across North America, there is no standardized protocol for acoustic data management, which limits the usability of these datasets for voice artificial intelligence (AI) research. OBJECTIVE: The aim was to capture current practices of voice data collection, storage, analysis, and perceived limitations to collaborative voice research. METHODS: A 30-question online survey was developed with expert guidance from the voicecollab.ai members, an international collaborative of voice AI researchers. The survey was disseminated via REDCap to an estimated 200 practitioners at North American voice centers. Survey questions assessed respondents' current practices in terms of acoustic data collection, storage, and retrieval as well as limitations to collaborative voice research. RESULTS: Seventy-two respondents completed the survey of which 81.7% were laryngologists and 18.3% were speech language pathologists (SLPs). Eighteen percent of respondents reported seeing 40%-60% and 55% reported seeing >60 patients with voice disorders weekly (conservative estimate of over 4000 patients/week). Only 28% of respondents reported utilizing standardized protocols for collection and storage of acoustic data. Although, 87% of respondents conduct voice research, only 38% of respondents report doing so on a multi-institutional level. Perceived limitations to conducting collaborative voice research include lack of standardized methodology for collection (30%) and lack of human resources to prepare and label voice data adequately (55%). CONCLUSION: To conduct large-scale multi-institutional voice research with AI, there is a pertinent need for standardization of acoustic data management, as well as an infrastructure for secure and efficient data sharing.

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, 2023.

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.

Factors Associated With Otolaryngologists Performing Tracheotomy.

Importance: Tracheotomies are frequently performed by nonotolaryngology services. The factors that determine which specialty performs the procedure are not defined in the literature but may be influenced by tracheotomy approach (open vs percutaneous) and other clinicodemographic factors. Objective: To evaluate demographic and clinical characteristics associated with tracheotomies performed by otolaryngologists compared with other specialists and to differentiate those factors from factors associated with use of open vs percutaneous tracheotomy. Design, Setting, and Participants: This multicenter, retrospective cohort study included patients aged 18 years or older who underwent a tracheotomy for cardiopulmonary failure at 1 of 8 US academic institutions between January 1, 2013, and December 31, 2016. Data were analyzed from September 2022 to July 2023. Exposure: Tracheotomy. Main Outcomes and Measures: The primary outcome was factors associated with an otolaryngologist performing tracheotomy. The secondary outcome was factors associated with use of the open tracheotomy technique. Results: A total of 2929 patients (mean [SD] age, 57.2 [17.2] years; 1751 [59.8%] male) who received a tracheotomy for cardiopulmonary failure (652 [22.3%] performed by otolaryngologists and 2277 [77.7%] by another service) were analyzed. Although 1664 of all tracheotomies (56.8%) were performed by an open approach, only 602 open tracheotomies (36.2%) were performed by otolaryngologists. Most tracheotomies performed by otolaryngologists (602 of 652 [92.3%]) used the open technique. Multivariable regression analysis revealed that self-reported Black race (odds ratio [OR], 1.89; 95% CI, 1.52-2.35), history of neck surgery (OR, 2.71; 95% CI, 2.06-3.57), antiplatelet and/or anticoagulation therapy (OR, 1.74; 95% CI, 1.29-2.36), and morbid obesity (OR, 1.54; 95% CI, 1.24-1.92) were associated with greater odds of an otolaryngologist performing tracheotomy. In contrast, history of neck surgery (OR, 1.36; 95% CI, 0.96-1.92), antiplatelet and/or anticoagulation therapy (OR, 0.80; 95% CI, 0.56-1.14), and morbid obesity (OR, 0.94; 95% CI, 0.74-1.19) were not associated with undergoing open tracheotomy when performed by any service, and Black race (OR, 0.56; 95% CI, 0.44-0.71) was associated with lesser odds of an open approach being used. Age-adjusted Charlson Comorbidity Index score greater than 4 was associated with greater odds of both an otolaryngologist performing tracheotomy (OR, 1.26; 95% CI, 1.03-1.53) and use of the open tracheotomy technique (OR, 1.48, 95% CI, 1.21-1.82). Conclusions and Relevance: In this study, otolaryngologists were significantly more likely than other specialists to perform a tracheotomy for patients with history of neck surgery, morbid obesity, and ongoing anticoagulation therapy. These findings suggest that patients undergoing tracheotomy performed by an otolaryngologist are more likely to present with complex and challenging clinical characteristics.

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.

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.

Hoarseness: When to observe and when to refer.

The terms hoarseness and dysphonia are used interchangeably, and both describe a type of altered vocal quality affecting one-third of patients. While hoarseness may be secondary to benign conditions such as reflux or viral laryngitis, it may suggest benign or malignant vocal-fold pathology. It is important for caregivers to know how to evaluate, treat, and when to refer patients for direct visualization via laryngoscopy. In this article, we review basic laryngeal anatomy and function, symptoms of vocal-fold pathology, and current guidelines from the American Academy of Otolaryngology-Head and Neck Surgery on the diagnosis and treatment of dysphonia, including patient referral.

Gender-Affirming Voice Modification for Transgender Women: Characteristics and Outcomes.

Objective: The primary aim of this study was to define characteristics of transgender women seeking gender-affirming voice modification at our voice center. The secondary aim was to evaluate outcome measures, comparing (a) behavioral voice training alone, (b) surgery alone, and (c) combination of behavioral voice training+surgery. Methods: Patients seen in a 30-month period, who sought care for gender-affirming voice modification, were included if they were assigned male at birth and identified as female. Patient demographic information, patient quality of life index scores, Trans Woman Voice Questionnaire (TWVQ), and acoustic data were collected before and after intervention. Results: Sixteen patients met inclusion criteria. The majority of patients were (a) undergoing hormone replacement therapy at initiation of treatment, (b) were presenting in public for over 2 years as female, and (c) had a history of psychological disorders (i.e., gender dysphoria, anxiety, depression, and attention deficit hyperactivity disorder [ADHD]). Increased f0 and decreased TWVQ scores were evident and statistically significant within behavioral voice training cohort and behavioral voice training+surgery cohort. Treatment groups appear similar with respect to average changes; pre- and post-data were not available for surgery only patients. Greater change in f0 was directly correlated with increased number of voice training sessions. Conclusion: There is variability in treatment course for patients seeking gender-affirming voice modification; however, treatment type may not impact outcomes. Increased patient quality of life and increased speaking fundamental frequency were found in this patient cohort.

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.

High Tracheal Resection With Intralaryngeal Extension as an Alternative to Cricotracheal Resection for Treatment of Subglottic Stenosis.

OBJECTIVE: Some patients with subglottic stenosis (SGS) require open airway reconstruction, which traditionally involves resection of the anterior cricoid cartilage. As an alternative, we present a novel technique: cricoid-sparing high tracheal resection with excision of subglottic stenotic tissue from below. A novel set of posterior circumferential cricoid sutures is used to reline the exposed cricoid plate. STUDY DESIGN: Retrospective chart review. SETTING: Single tertiary care center. METHODS: The surgical technique is described and illustrated. A chart review was performed for all patients who underwent surgery between January 1, 2016, and June 30, 2021. RESULTS: Fourteen patients (100% female) underwent this airway resection and reconstruction surgery during the study time period. After a mean follow-up of 12 months, no patients required tracheostomy. Twelve of 14 patients (86%) had durable airways. Two patients (14%) have required repeated endoscopic procedures for recurrent stenosis and are considered treatment failures. None exhibited postoperative dysfunction to suggest posterior cricoarytenoid muscle injury. Thirteen patients (93%) had a postoperative normal voice or only transient dysphonia. One patient had permanent unilateral vocal fold paralysis. CONCLUSION: Cricoid-sparing high tracheal resection is a safe and effective alternative to cricotracheal resection, especially for predominantly posterior SGS. The cricoid cartilage and cricothyroid muscles are left undisturbed, potentially decreasing the risk of postoperative dysphonia, namely lowered fundamental frequency. This is especially meaningful in the setting of a predominantly female patient population.

Comparative Treatment Outcomes for Idiopathic Subglottic Stenosis: 5-Year Update.

The North American Airway Collaborative (NoAAC) previously published a 3-year multi-institutional prospective cohort study showing variation in treatment effectiveness between 3 primary surgical techniques for idiopathic subglottic stenosis (iSGS). In this report, we update these findings to include 5 years of data evaluating treatment effectiveness. Patients in the NoAAC cohort were re-enrolled for 2 additional years and followed using the prespecified published protocol. Consistent with prior data, prospective observation of 487 iSGS patients for 5 years showed treatment effectiveness differed by modality. Cricotracheal resection maintained the lowest rate of recurrent operation (5%), followed by endoscopic resection with adjuvant medical therapy (30%) and endoscopic dilation (50%). These data support the initial observations and continue to provide value to providers and patients navigating longitudinal decision-making. Level of evidence: 2-prospective cohort study.

Clinicodemographic Predictors of Tracheotomy Tube Size and Decannulation: A Multiinstitutional Retrospective Cohort Study on Tracheotomy.

OBJECTIVE: We aimed to discern clinico-demographic predictors of large (≥8) tracheostomy tube size placement, and, secondarily, to assess the effect of large tracheostomy tube size and other parameters on odds of decannulation before hospital discharge. SUMMARY OF BACKGROUND DATA: Factors determining choice of tracheostomy tube size are not well-characterized in the current literature, despite evidence linking large tracheostomy tube size with posttracheotomy tracheal stenosis. The effect of tracheostomy tube size on timing of decannulation is also unknown, an important consideration given reported associations between endotracheal tube size and probability of failed extubation. METHODS: We collected information pertaining to patients who underwent tracheotomy at 1 of 10 U.S. health care institutions between 2010 and 2019. Tracheostomy tube size was dichotomized (≥8 and <8). Multivariable logistic regression models were fit to identify predictors of (1) large tracheostomy tube size, and (2) decannulation before hospital discharge. RESULTS: The study included 5307 patients, including 2797 (52.7%) in the large tracheostomy cohort. Patient height (odds ratio [OR] = 1.060 per inch; 95% confidence interval [CI] 1.041-1.070) and obesity (1.37; 95% CI 1.1891.579) were associated with greater odds of large tracheostomy tube; otolaryngology performing the tracheotomy was associated with significantly lower odds of large tracheostomy tube (OR = 0.155; 95% CI 0.131-0.184). Large tracheostomy tube size (OR = 1.036; 95% CI 0.885-1.213) did not affect odds of decannulation. CONCLUSIONS: Obesity was linked with increased likelihood of large tracheostomy tube size, independent of patient height. Probability of decannulation before hospital discharge is influenced by multiple patient-centric factors, but not by size of tracheostomy tube.

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.

Laryngology Outcomes Following Implantable Vagus Nerve Stimulation.

Importance: Vagus nerve stimulation (VNS) devices have gained widespread acceptance for treatment of resistant epilepsy and depression. The increasing number of procedures has resulted in an increasing number of iatrogenic injuries to the vagus nerve, which can have a significant effect on vocalization and quality of life. Objective: To determine the relative frequency of laryngeal adverse effects reported to the US Food and Drug Administration (FDA) after VNS implantation and to analyze associated VNS device problems. Design, Setting, and Participants: This retrospective cross-sectional analysis queried the FDA Manufacturer and User Facility Device Experience database of adverse events in the US between 1996 and 2020. Main Outcomes and Measures: The primary outcome was the percent of adverse events reported to the FDA that included patients who received VNS with laryngeal adverse effects and the associated proportion of device problems after VNS surgery. Results: A total of 12 725 iatrogenic vagus nerve issues were documented after VNS implantation, with apnea (n = 395; 3.1%) being the most common patient problem. Overall, 187 reports of laryngeal adverse effects associated with VNS devices were identified and represented the eighth most common iatrogenic vagus nerve problem reported to the FDA. Laryngeal adverse effects included 78 reports of voice alteration and 57 reports of paresis/paralysis. The VNS device problems frequently associated with laryngeal adverse effects were high impedance (n = 15, 8.02%), incorrect frequency delivery (n = 10, 5.35%), and battery problems (n = 11, 5.88%). The number of laryngeal adverse effect reports per year peaked in 2012 with 43 cases. Conclusions and Relevance: This cross-sectional study found that although the literature demonstrates that vocal changes occur with nearly all VNS devices, the FDA receives adverse event reports of voice changes. Our results emphasize a potential need to improve patient counseling prior to VNS surgery to better set patient expectations regarding vocal changes and to prevent unnecessary patient concern. In addition, reports of vocal fold paresis/paralysis potentially suggest that patients may benefit from preoperative laryngeal assessment to differentiate preexisting vocal fold paralysis from that caused by VNS surgery.
