Laryngeal Recalibration Therapy Improves Laryngopharyngeal Symptoms in Patients With Suspected Laryngopharyngeal Reflux Disease.

INTRODUCTION: Laryngopharyngeal symptoms such as cough, throat clearing, voice change, paradoxic vocal fold movement, or laryngospasm are hyper-responsive behaviors resulting from local irritation (e.g., refluxate) and heightened sympathetic tone. Laryngeal recalibration therapy (LRT) guided by a speech-language pathologist (SLP) provides mechanical desensitization and cognitive recalibration to suppress hyper-responsive laryngeal patterns. The aim of this study was to assess symptom response to LRT among patients with chronic laryngopharyngeal symptoms undergoing evaluation of gastroesophageal reflux disease (GERD). METHODS: Adults with chronic laryngopharyngeal symptoms referred for evaluation of GERD to a single center were prospectively followed. Inclusion criteria included ≥2 SLP-directed LRT sessions. Data from endoscopy, ambulatory reflux monitoring, and patient-reported outcomes were collected when available. The primary outcome was symptom response. RESULTS: Sixty-five participants completed LRT: mean age 55.4 years (SD 17.2), 46 (71%) female, mean body mass index 25.6 kg/m 2 (6.8), and mean of 3.7 (1.9) LRT sessions. Overall, 55 participants (85%) met criteria for symptom response. Specifically, symptom response was similar between those with isolated laryngopharyngeal symptoms (13/15, 87%) and concomitant laryngopharyngeal/esophageal symptoms (42/50, 84%). Among participants who underwent reflux monitoring, symptom response was similar between those with proven, inconclusive for, and no GERD (18/21 [86%], 8/9 [89%], 10/13 [77%]). DISCUSSION: Eighty-five percent of patients with chronic laryngopharyngeal symptoms referred for GERD evaluation who underwent LRT-experienced laryngeal symptom response. Rates of symptom response were maintained across patients with or without proven GERD and patients with or without concomitant esophageal reflux symptoms. SLP-directed LRT is an effective approach to incorporate into multidisciplinary management of chronic laryngopharyngeal symptoms/laryngopharyngeal reflux disease.

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.

Association of race and health care system with disease stage and survival in veterans with larynx cancer.

BACKGROUND: Black patients with laryngeal squamous cell carcinoma (LSCC) historically have inferior outcomes in comparison with White patients. The authors investigated these racial disparities within the Veterans Health Administration (VHA), an equal-access system, and within the Surveillance, Epidemiology, and End Results (SEER) program, which is representative of the US hybrid-payer system. METHODS: Patients with invasive (T1 or greater) LSCC were included from SEER (2004-2015) and the VHA (2000-2017). The primary outcomes of overall survival (OS) and larynx cancer-specific survival (LCS) were evaluated in Cox and Fine-Gray models. RESULTS: In the SEER cohort (7122 patients: 82.6% White and 17.4% Black), Black patients were more likely to present with advanced disease and had inferior OS (hazard ratio [HR], 1.37; 95% CI, 1.26-1.50; P < .0001) in a multivariable analysis. Black LCS was worse in a univariable analysis (HR, 1.42; 95% CI, 1.27-1.58; P < .0001), but this effect was attenuated by 83% when the authors controlled for the TNM category and was found to be insignificant in a multivariable analysis (HR, 1.05; 95% CI, 0.93-1.18; P = .42). In the VHA cohort (9248 patients: 79.7% White and 20.3% Black), the 2 racial cohorts presented with similar tumor characteristics and similar OS (HR, 0.95; 95% CI, 0.89-1.02; P = .14). Black LCS was similar in univariable (HR, 1.10; 95% CI, 1.00-1.22; P = .05) and multivariable analyses (HR, 1.02; 95% CI, 0.92-1.14; P = .67). CONCLUSIONS: Black patients with LSCC had a tumor burden at diagnosis and survival outcomes comparable to those of White patients within the VHA; this was counter to what was observed in the SEER analysis and prior national trends. This study's findings point toward the notable role of health care access in contributing to racial health disparities in the realm of larynx cancer.

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.

Molecular targeting of papillary thyroid carcinoma with fluorescently labeled ratiometric activatable cell penetrating peptides in a transgenic murine model.

BACKGROUND AND OBJECTIVES: Molecularly targeted fluorescent molecules may help detect tumors that are unseen by traditional white-light surgical techniques. We sought to evaluate a fluorescent ratiometric activatable cell penetrating peptide (RACPP) for tumor detection in a transgenic model of PTC. METHODS: Thirteen BRAFV600E mice with PTC were studied-seven injected intravenously with RACPP, four controls with saline. Total thyroidectomy was performed with microscopic white-light visualization. Fluorescent imaging of post-thyroidectomy fields was performed, and tissue with increased signal was removed and evaluated for PTC. Final samples were analyzed by a pathologist blinded to conditions. Vocal cord function was evaluated postoperatively with video laryngoscopy. RESULTS: The average in situ ratiometric (Cy5/Cy7) thyroid tumor-to-background contrast ratio was 2.27 +/- 0.91. Fluorescence-guided clean-up following thyroidectomy identified additional tumor in 2 of 7 RACPP animals (smallest dimension 1.2 mm), and decreased the number of animals with residual tumor from 4 to 3. All retained tumor foci on final pathology were smaller than 0.76 mm. Intact vocal abduction was present in all of the RACPP animals. CONCLUSIONS: RACPPs successfully targeted PTC in a transgenic thyroidectomy model, and allowed for residual tumor detection that reduced positive margins beyond what was possible with white-light surgery alone.

Upper Esophageal Sphincter and Esophageal Motility Pathology on Manometry in Retrograde Cricopharyngeal Dysfunction.

OBJECTIVE: There exists a paucity of data regarding the mechanism and manometric findings in retrograde cricopharyngeal dysfunction (RCPD). In this study, we aimed to compare esophageal physiologic findings between patients with RCPD compared to an asymptomatic cohort. STUDY DESIGN: Case-control study. SETTING: Tertiary Care Center. METHODS: Esophageal high-resolution impedance manometry was completed preoperatively in patients diagnosed with RCPD. Manometric data were compared between the RCPD and asymptomatic cohorts. A 2:1 age-sex-matched asymptomatic cohort was used as the control group. Treatment response was assessed among the RCPD cohort. RESULTS: Thirty-nine patients are included: 13 RCPD [mean age: 31.1 (SD: 12.6) years, female sex: 11 (85%)] and 26 asymptomatic [mean age: 32.1 (SD: 1.5) years, female sex: 22 (85%)]. The RCPD cohort, compared to the asymptomatic cohort, exhibited significantly greater upper esophageal sphincter (UES) length [4.5 (SD: 0.7) vs 3.7 (0.9) cm, P = .01] and higher UES basal pressures [91.9 (35.0) vs 49.7 (25.5) mm Hg, P = .002]. Patients with RCPD demonstrated higher rates of ineffective swallows [70.0% (31.6%) vs 15.4% (21.6%), P < .001] and incomplete bolus clearance [81% (22.0%) vs 21.8% (30.0%), P < .001]. All patients who underwent cricopharyngeal botulinum injections experienced initial improvement of symptoms with 3 patients requiring repeat intervention. CONCLUSION: RCPD is associated with a longer UES, elevated UES basal pressures, and an increased incidence of ineffective esophageal motility. This study is the first to compare preoperative manometry results among patients with RCPD to those of an asymptomatic cohort, providing insights into the mechanism of RCPD.

Transitions of care: An aerodigestive provider assessment survey.

OBJECTIVE: To create, validate, and apply an aerodigestive provider assessment survey. METHODS: A survey assessing provider knowledge and current practice in the transition of patients with chronic aerodigestive disorders from pediatric to adult care was drafted by a multidisciplinary expert panel. Once agreement of the initial survey items was obtained, the survey was distributed to a national multidisciplinary panel of aerodigestive experts for review. Responses from the national panel were systematically quantified and a content validity index (CVI) was calculated. A final survey was developed and distributed to pediatric and adult aerodigestive providers. RESULTS: From the initial 22 items presented to the national panel, 20 of the initial questions were included in the final instrument. Two additional questions were developed as a result of feedback from the expert panel. All items included in the survey had an Item Content Validity Index (I-CVI) of >0.85. The average Scale CVI in proportion to the average proportion of relevance (S-CVI/Ave) for the tool was 0.88. The average Scale CVI in proportion to universal agreement (S-CVI/UA) was 0.52. The survey was then administered to pediatric and adult specialty providers at our institution. Twenty-two providers completed the final survey. CONCLUSION: The content validity index measurements from this newly developed survey suggest that it is a valid tool for assessing current knowledge and practice in care transitions among patients with complex aerodigestive needs. The survey developed in this project has been used to identify knowledge gaps and process issues that can be addressed to ease the transition of adolescents from pediatric specialty care into adult specialty care.

A Multidisciplinary Minimally Invasive Approach Is Necessary for the Contemporary Management of Esophageal Diverticula.

Background: Esophageal diverticula were traditionally treated with open surgery, which is associated with significant morbidity and mortality rates. Management has shifted to minimally invasive approaches with several advantages. We examine outcomes in patients with esophageal diverticula treated with minimally invasive techniques by a multidisciplinary surgical team at a single center. Materials and Methods: A retrospective review of a prospectively maintained database was performed for patients who underwent minimally invasive surgery for esophageal diverticula at our institution from June 2010 to December 2022. Primary outcomes were 30-day morbidity and mortality rates. Secondary outcomes were symptom resolution, length of stay (LOS), readmission, and need for reintervention. Results: A total of 28 patients were identified. Twelve patients had pharyngeal diverticula, 7 patients had midesophageal diverticula, and 9 patients had epiphrenic diverticula. Thirty-day morbidity and readmission rates were 10.7% (3 patients), 1 pharyngeal (sepsis), 1 midesophageal (refractory nausea), and 1 epiphrenic (poor oral intake). There were no esophageal leaks. Average LOS was 2.3 days, with the pharyngeal group experiencing a significantly shorter LOS (1.3 days versus 3.4 days for midesophageal, P < .01 versus 2.8 days for epiphrenic, P < .05). Symptom resolution after initial operation was 78.6%. Reintervention rate was 17.9%, and symptom resolution after reintervention was 100%. There were no mortalities. Conclusion: This study demonstrates that esophageal diverticula can be repaired safely and efficiently when performed by a multidisciplinary team utilizing advanced minimally invasive endoscopic and robotic surgical techniques. We advocate for the management of this rare condition at a high-volume center with extensive experience in foregut surgery.

New Medical Device and Therapeutic Approvals in Otolaryngology: State of the Art Review of 2022.

Objective: To review new drugs and devices relevant to otolaryngology approved by the Food and Drug Administration (FDA) in 2022. Data Sources: Publicly available FDA data on drugs and devices approved in 2022. Review Methods: A preliminary screen was conducted to identify drugs and devices relevant to otolaryngology. A secondary screen by members of the American Academy of Otolaryngology-Head and Neck Surgery's (AAO-HNS) Medical Devices and Drugs Committee differentiated between minor updates and new approvals. The final list of drugs and devices was sent to members of each subspecialty for review and analysis. Conclusion: A total of 1251 devices and 37 drugs were identified on preliminary screening. Of these, 329 devices and 5 drugs were sent to subspecialists for further review, from which 37 devices and 2 novel drugs were selected for further analysis. The newly approved devices spanned all subspecialties within otolaryngology. Many of the newly approved devices aimed to enhance patient experience, including over-the-counter hearing aids, sleep monitoring devices, and refined CPAP devices. Other advances aimed to improve surgical access, convenience, or comfort in the operating room and clinic. Implications for Practice: Many new devices and drugs are approved each year to improve patient care and care delivery. By staying up to date with these advances, otolaryngologists can leverage new innovations to improve the safety and quality of care. Given the recent approval of these devices, further studies are needed to assess long-term impact within the field of otolaryngology.

Impact of Obesity on Timing of Tracheotomy: A Multi-institutional Retrospective Study.

OBJECTIVE: To examine the impact of increased body mass index (BMI) on (1) tracheotomy timing and (2) short-term surgical complications requiring a return to the operating room and 30-day mortality utilizing data from the Multi-Institutional Study on Tracheotomy (MIST). METHODS: A retrospective analysis of patients from the MIST database who underwent surgical or percutaneous tracheotomy between 2013 and 2016 at eight institutions was completed. Unadjusted and adjusted logistic regression analyses were used to assess the impact of obesity on tracheotomy timing and complications. RESULTS: Among the 3369 patients who underwent tracheotomy, 41.0% were obese and 21.6% were morbidly obese. BMI was associated with higher rates of prolonged intubation prior to tracheotomy accounting for comorbidities, indication for tracheotomy, institution, and type of tracheostomy (p = 0.001). Morbidly obese patients (BMI ≥35 kg/m2) experienced a longer duration of intubation compared with patients with a normal BMI (median days intubated [IQR 25%-75%]: 11.0 days [7-17 days] versus 9.0 days [5-14 days]; p < 0.001) but did not have statistically higher rates of return to the operating room within 30 days (p = 0.12) or mortality (p = 0.90) on multivariable analysis. This same finding of prolonged intubation was not seen in overweight, nonobese patients when compared with normal BMI patients (median days intubated [IQR 25%-75%]: 10.0 days [6-15 days] versus 10.0 days [6-15 days]; p = 0.36). CONCLUSION: BMI was associated with increased duration of intubation prior to tracheotomy. Although morbidly obese patients had a longer duration of intubation, there were no differences in return to the operating room or mortality within 30 days.

Developing a Tracheal Rendezvous Procedure for Complete High Subglottic Stenosis.

Complete subglottic stenosis is often managed with surgical resection. However, involvement of the high subglottis can limit candidacy for open resection, and there are few treatment options for these patients. We refined an endoscopic approach that evolved into a tracheal rendezvous technique with T-tube placement as an alternative to open surgical resection. Here, we present our series, technique, and outcomes. A retrospective review was performed to identify patients who underwent endoscopic management of complete high subglottic stenosis at the University of California San Diego. The surgical technique was initially a two-step staged procedure and was subsequently revised to a single-stage procedure with stenosis ablation, dilation, and insertion of a T-tube, which was completed in one day. Patients were seen at regular follow-up intervals for reassessment. Five patients were identified with complete stenosis not amenable to surgical resection. The average age of the cohort was 44.8 years. The etiology of stenosis in all patients was related to prolonged intubation and tracheostomy, and the average length of stenosis was 19.6 mm. Stenosis resection was accomplished via laser ablation and balloon dilation, and the average T-tube length was 50.3 mm. All patients were discharged on postoperative day one. Two patients developed airway crusting within the T-tube and required emergency department visits. Decannulation was attempted in three patients, although failed in two. Tracheal rendezvous is a safe and effective procedure for patients with grade IV subglottic stenosis. This provides a feasible endoscopic alternative to patients who are not candidates for open surgical resection, ye are motivated to have phonatory capacity.

Tracheal Transection After Prolonged Intubation and Tracheostomy: A Case Report.

Tracheal transection is a rare, life-threatening complication after tracheal injury. Most commonly, tracheal transection presents after blunt trauma, but iatrogenic tracheal transection after tracheotomy has not been well described. Here, we present a case without a history of trauma that presented with signs of symptoms of tracheal stenosis. She was taken to the operating room for tracheal resection and anastomosis and was incidentally found to have a complete tracheal transection intraoperatively.

Transoral Laser Microsurgery With Neck Dissection Versus Radiotherapy for T2N0 Supraglottic Cancer.

OBJECTIVES: To compare overall survival outcomes associated with transoral laser microsurgery (TLM) with neck dissection versus definitive radiotherapy in the management of T2N0 supraglottic squamous cell carcinoma. METHODS: Data were extracted from the National Cancer Database concerning patients with cT2N0M0 supraglottic cancer treated with either TLM and neck dissection with minimum lymph node yield of 10 or definitive radiotherapy. Predictors of overall survival were assessed via Cox proportional hazards regression. RESULTS: Seventy-six cT2N0 supraglottic squamous cell carcinoma patients who underwent TLM with neck dissection (+/- adjuvant therapy) versus 991 patients who underwent radiotherapy. TLM was associated with an overall survival benefit (OR = 0.574; 95% CI 0.383-0.860) compared with radiotherapy. There was no difference in survival between TLM patients receiving adjuvant treatment and those receiving definitive radiotherapy. CONCLUSIONS: An up-front, TLM-based surgical approach to cT2N0 supraglottic cancer may offer an overall survival benefit compared with definitive radiotherapy, and should receive more frequent consideration as a primary approach to this disease process. LEVEL OF EVIDENCE: 3 Laryngoscope, 133:601-606, 2023.

Differentiation of Bolus Texture During Deglutition via High-Density Surface Electromyography: A Pilot Study.

OBJECTIVE: Swallowing is a complex neuromuscular task. There is limited spatiotemporal data on normative surface electromyographic signal during swallow, particularly across standard textures. We hypothesize the pattern of electromyographic signal of the anterior neck varies cranio-caudally, that laterality can be evaluated, and categorization of bolus texture can be differentiated by high-density surface electromyography (HDsEMG) through signal analysis. METHODS: An HDsEMG grid of 20 electrodes captured electromyographic activity in eight healthy adult subjects across 240 total swallows. Participants swallowed five standard textures: saliva, thin liquid, puree, mixed consistency, and dry solid. Data were bandpass filtered, underwent functional alignment of signal, and then placed into binary classifier receiver operating characteristic (ROC) curves. Muscular activity was visualized by creating two-dimensional EMG heat maps. RESULTS: Signal analysis results demonstrated a positive correlation between signal amplitude and bolus texture. Greater differences of amplitude in the cranial most region of the array when compared to the caudal most region were noted in all subjects. Lateral comparison of the array revealed symmetric power levels across all subjects and textures. ROC curves demonstrated the ability to correctly classify textures within subjects in 6 of 10 texture comparisons. CONCLUSION: This pilot study suggests that utilizing HDsEMG during deglutition can noninvasively differentiate swallows of varying texture noninvasively. This may prove useful in future diagnostic and behavioral swallow applications. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:2695-2703, 2023.

Quantitative prediction of aspiration risk in head and neck cancer patients treated with radiation therapy.

OBJECTIVE: To determine characteristics most strongly associated with risk for aspiration events among head and neck cancer (HNC) patients undergoing curative intent treatment. MATERIALS AND METHODS: This was a retrospective, cross-sectional study of 106 patients with previously untreated HNC who received definitive or postoperative radiation therapy (RT) +/- systemic therapy with curative intent. Patients who received post-treatment videofluoroscopic swallow study (VFSS) between 2018-2021 were included. Using ordinal multivariable logistic regression, we modeled the effects of age (>60 years vs. ≤60 years), sex, body mass index (BMI) (>20 kg/m2 vs. ≤20 kg/m2), American Joint Committee on Cancer 8th edition stage (I-II vs. III-IVB), treatment with cisplatin (vs. other or no systemic therapy), post-operative status, primary site (oral cavity vs. P16+ oropharynx vs. P16- Mucosal Site vs. other), and quantitative VFSS measures on Penetration-Aspiration Scale (PAS) score. RESULTS AND CONCLUSION: On ordinal multivariable logistic regression, age >60 years (odds ratio (OR): 3.91, 95% confidence interval (CI): 1.29, 11.9), advanced stage (stage III-IVB) (OR: 3.13, 95% CI: 1.23, 7.79), pharyngeal constriction ratio (PCR) >0.25 (OR: 3.65, 95% CI: 1.14, 11.7), and bolus clearance ratio (BCR) > 0.10 (OR: 3.42, 95% CI: 1.20, 9.75) were found to be significant risk factors for higher PAS scores. Patients with ≥ 2 pre-treatment risk factors had statistically significant increased risk for post-treatment aspiration (OR 2.52, 95% CI: 1.31, 4.86) on ordinal logistic regression. This model could be useful to direct high-risk patients toward interventions designed to reduce risk of aspiration events.

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 ram sign: detecting previously undiagnosed congenital laryngeal clefts in adults.

OBJECTIVES: We present the clinical characteristics of a case series of adult patients with type III laryngeal clefts according to the classification of Benjamin and Inglis, in an attempt to make practitioners aware of the "ram sign," a clinical finding associated with laryngeal clefts in adults. Laryngeal clefts are uncommon defects that are nearly universally identified during infancy as a result of persistent aspiration and pneumonia. Undiagnosed laryngeal clefts in adults are extremely rare. METHODS: Three type III laryngeal clefts were identified in adults (29, 48, and 60 years of age) from one clinic over an 18-month period. The existing literature features only one type III cleft, to our knowledge. The 60-year-old patient represents the oldest person in the English-language literature to have a newly diagnosed laryngeal cleft. All three cases presented with various degrees of aspiration over an extended period. RESULTS: The computed tomographic imaging and endoscopic findings from these three patients were reviewed. The videolaryngoscopic images demonstrated that the "ram sign"--an endoscopic finding associated with redundant soft tissue overlying the arytenoid cartilages that prolapses into the cleft, creating the appearance of ram's horns--was a consistent and striking feature in all three patients. CONCLUSIONS: Although rare, laryngeal clefts may represent an underdiagnosed entity in the adult population. With increased awareness, they may be identified more frequently as a treatable cause of aspiration and recurrent pneumonia.
