Objectives: The goal of this study was to evaluate the benefit of sublesional bevacizumab injection for recurrent respiratory papillomatosis (RRP) as used in a typical clinical practice. Methods: A retrospective review of patients with RRP treated between 2011 and 2016 was undertaken. All patients were treated with in-office potassium titanyl phosphate (KTP) laser photoablation. Sublesional bevacizumab injection was used based on joint patient-physician decision making. Papilloma burden was objectively measured on prior recordings by 2 blinded reviewers and described as vocal fold segments affected (VFSA) by papilloma. Each patient served as their own control by comparing times when bevacizumab was or was not used. Mixed model for longitudinal data was used to determine if the previous use of bevacizumab decreased the disease burden. Results: A total of 19 patients met inclusion criteria and all prior laryngoscopic exams were reviewed for VFSA as described above. The mean (SD) number of VFSA when bevacizumab was not used at the prior procedure was 15 (14) as compared to 8 (11) when bevacizumab was used. When adjusted for age, time from initial presentation and baseline disease burden, mixed model showed a decrease of 11 VFSA (95% CI 6.5, 15.5, P < .0001) when bevacizumab was used as compared to when bevacizumab was not used at the prior procedure. In mixed model analysis, there was not a significant association between bevacizumab dose used and VFSA at the subsequent visit ( P = .8). Conclusion: Using sublesional bevacizumab intermittently based on clinical findings appears to be effective in improving disease control. Papilloma burden is significantly decreased at the subsequent clinical follow-up following injection of sublesional bevacizumab. The beneficial effect of sublesional bevacizumab may be not be dose-dependent.

Objectives: To examine whether social determinants of health (SDH) factors are associated with time to diagnosis, treatment selection, and time to recurrent surgical intervention in idiopathic subglottic stenosis (iSGS) patients. Methods: Adult patients with diagnosed iSGS were recruited prospectively (2015-2017) via clinical providers as part of the North American Airway Collaborative (NoAAC) and via an online iSGS support community on Facebook. Patient-specific SDH factors included highest educational attainment (self-reported), median household income (matched from home zip code via U.S. Census data), and number of close friends (self-reported) as a measure of social support. Main outcomes of interest were time to disease diagnosis (years from symptom onset), treatment selection (endoscopic dilation [ED] vs cricotracheal resection [CTR] vs endoscopic resection with adjuvant medical therapy [ERMT]), and time to recurrent surgical intervention (number of days from initial surgical procedure) as a surrogate for disease recurrence. Results: The total 810 participants were 98.5% female, 97.2% Caucasian, and had a median age of 50 years (IQR, 43-58). The cohort had a median household income of $62 307 (IQR, $50 345-$79 773), a median of 7 close friends (IQR, 4-10), and 64.7% of patients completed college or graduate school. Education, income, and number of friends were not associated with time to diagnosis via multivariable linear regression modeling. Univariable multinominal logistic regression demonstrated an association between education and income for selecting ED versus ERMT, but no associations were noted for CTR. No associations were noted for time to recurrent surgical procedure via Kaplan Meier modeling and Cox proportional hazards regression. Conclusions: Patient education, income, and social support were not associated with time to diagnosis or time to disease recurrence. This suggests additional patient, procedure, or disease-specific factors contribute to the observed variations in iSGS surgical outcomes.

Post-transplant lymphoproliferative disorder (PTLD) is a unifying term for a spectrum of lymphoid expansion entities brought about by immunosuppression. It can present throughout the head and neck, and tonsillar involvement is not limited to children. We report the case of a 67-year-old woman who developed odynophagia associated with putrid halitosis 4 months after she had undergone renal transplantation. Direct visualization of the oropharynx revealed multiple sites of severe ulceration and erythema, with erosion of both the anterior and posterior right tonsillar pillars and a necrotic ulceration fistulating deeply. Biopsy analysis led to a diagnosis of PTLD. The patient underwent rituximab monotherapy and responded well. However, after the cessation of therapy, she experienced a recurrence that necessitated chemotherapy, which resulted in a lasting remission. At follow-up 5 years later, she remained PTLD-free with stable stage 4 chronic kidney disease.

Objectives/HypothesisThe purpose of this study is to develop consensus on key points that would support the use of systemic bevacizumab for the treatment of recurrent respiratory papillomatosis (RRP), and to provide preliminary guidance surrounding the use of this treatment modality.Study DesignDelphi method‐based survey series.MethodsA multidisciplinary, multi‐institutional panel of physicians with experience using systemic bevacizumab for the treatment of RRP was established. The Delphi method was used to identify and obtain consensus on characteristics associated with systemic bevacizumab use across five domains: 1) patient characteristics; 2) disease characteristics; 3) treating center characteristics; 4) prior treatment characteristics; and 5) prior work‐up.ResultsThe international panel was composed of 70 experts from 12 countries, representing pediatric and adult otolaryngology, hematology/oncology, infectious diseases, pediatric surgery, family medicine, and epidemiology. A total of 189 items were identified, of which consensus was achieved on Patient Characteristics (9), Disease Characteristics (10), Treatment Center Characteristics (22), and Prior Workup Characteristics (18).ConclusionThis consensus statement provides a useful starting point for clinicians and centers hoping to offer systemic bevacizumab for RRP and may serve as a framework to assess the components of practices and centers currently using this therapy. We hope to provide a strategy to offer the treatment and also to provide a springboard for bevacizumab's use in combination with other RRP treatment protocols. Standardized delivery systems may facilitate research efforts and provide dosing regimens to help shape best‐practice applications of systemic bevacizumab for patients with early‐onset or less‐severe disease phenotypes.Level of Evidence5 Laryngoscope, 131:E1941–E1949, 2021

Purpose This clinical focus article introduces primary and secondary muscle tension dysphagia (MTDg) as a functional idiopathic dysphagia that is often encountered in the otolaryngology clinic setting. Critical aspects of clinical assessment and treatment approaches will be discussed. The presented case study will describe a multidisciplinary evaluation and efficacy of therapy. Conclusions MTDg is a diagnosis of exclusion for a functional idiopathic swallowing disorder associated with abnormal laryngeal muscle tension. Abnormal laryngeal muscle tension is often associated with disorders of laryngeal hyperresponsiveness such as muscle tension dysphonia, chronic cough, globus pharyngeus, and paradoxical vocal fold motion. MTDg patients may exhibit concurrent disorders of laryngeal hyperresponsiveness. Proper dysphagia and gastroesophageal screening are critical in diagnosis of MTDg and must not be omitted. Our studies have shown high treatment efficacy with unloading of laryngeal muscle tension with the use of voice therapy technique utilized in treatment of muscle tension dysphonia.

Objective: To determine factors contributing to disease etiology and treatment efficacy. Study Design: Original Report. Setting: Tertiary academic center. Methods: IRB approved prospective study of 20 patients with reported dysphagia who exhibited normal oropharyngeal and esophageal swallowing function as evidenced by videofluoroscopic swallow study, esophagogastroduodenoscopy, high-resolution esophageal manometry with stationary impedance, and Bravo pH probe off proton pump inhibitor. Patients underwent speech-language pathology intervention. Results: Atypical laryngeal muscle tension was present in 100% of patients. Forty percent of patients had diagnosed positive gastroesophageal reflux disease. Sixty-five percent of patients showed signs of non-specific laryngeal inflammation and laryngeal hyperresponsiveness during strobolaryngoscopy. All patients reported a mean of 90% recovery by the completion of voice therapy directed toward unloading muscle tension. Conclusion: The study results suggest an association between laryngeal muscle tension and these patients’ dysphagia symptoms regardless of associated conditions. Speech-language pathology intervention showed high treatment efficacy. Level of Evidence: 2c- Outcomes research.

AbstractBackgroundThe aim of the study was to describe a novel technique for reinforcement of salvage laryngectomy closure using a bipedicled musculofascial submental flap.MethodsA retrospective cohort study design identified patients who underwent salvage laryngectomy reinforcement with a bipedicled submental hammock flap between January 2008 and December 2016 were compared to salvage laryngectomy patients treated with primary closure of the neopharynx during the same time period. Pharyngocutaneous fistula rates were compared between groups.ResultsPharyngocutaneous fistula rate in the submental hammock group (2/31, 6.5%) was significantly lower compared to the primary closure group (14/45, 31%, P < .05).ConclusionThe bipedicled musculofascial submental hammock flap is a viable method for reinforcement of salvage laryngectomy defects. It has a favorable pharyngocutaneous fistula rate compared to primary closure alone and has unique advantages over conventional methods of reinforcement.

Objectives/Introduction: Laryngology is an expanding field that has been increasingly incorporated into otolaryngology resident training programs nationwide. The exposure to the field is variable across training programs, despite the fact that laryngological complaints comprise a large proportion of consultations to otolaryngologists. Laryngology education is vital for the care of patients with voice, swallowing, and airway complaints as well as for the appropriate referral of patients to the laryngology team for specialized care. Speech-language pathologists (SLPs) specialized in voice and swallowing disorders are well-trained in the assessment and treatment for these populations. This team recently published a paper regarding the experience of laryngology education in residency. During analysis of the results, an interesting beneficial trend developed regarding the positive impact of exposure to SLPs. This appeared to be distinct and deserved further analysis and discussion. We propose that involving SLPs in resident education may greatly enhance their training in laryngology. Methods: As per our previous paper, a cross sectional, multi-institutional study was designed to assess the exposure of residents to laryngology. Descriptive statistics were obtained for questions involving exposure to SLPs. Fisher’s exact test was used to compare differences between groups. Results: Most respondents (135/151, 89.4%) indicated having SLPs specializing in voice and swallowing disorders in their departments, although only half (77/151, 51.0%) stated that they spent formal time with them during training. Results show that residents with formal training with SLPs were more comfortable interpreting videofluoroscopic swallow studies (VFSS) ( P = .0032). Residents with SLPs in their departments were also more likely to feel confident in terminology to describe different dysphonic voices ( P = .0213). Conclusion: Formal time with SLPs within otolaryngology residency programs varies across the country. Speech-language pathologists are a useful resource for laryngology resident training and should be included in their education.

Objectives: The primary objectives were to report oncologic outcomes of transoral laser microsurgery with potassium-titanyl-phosphate (KTP) laser (TLM-KTP) ablation of early glottic cancer (EGC). The secondary objectives were to report vocal outcomes and to analyze factors that might influence outcomes. Methods: A multi-institutional, retrospective analysis of consecutive patients treated for T1 or T2 glottic squamous cell carcinoma undergoing TLM-KTP ablation with at least 2 years of follow-up was performed. Patients with prior radiation or surgery for laryngeal disease were excluded. Primary outcome measures included: surgical failures requiring radiation or laryngectomy, disease-specific survival (DSS), and overall survival (OS). Secondary outcome measures included: pre- and postoperative Voice Handicap Index-10 (VHI-10) scores. The effects of smoking status, stage, and anterior commissure involvement on outcomes were analyzed. Results: Overall 88 patients met inclusion criteria (83% male, 79.5% current or former smokers). Mean age was 68 (standard deviation (SD): 12). Mean follow-up was 39.5 months (SD: 15.3). Staging included 50 T1a, 21 T1b, and 20 T2 tumors, including three metachronous second primaries. Radiation and/or laryngectomy avoidance was achieved in 87/88 (98.9%) of patients, inclusive of 24 patients requiring KTP re-treatments. Two patients had biopsy-proven recurrence (2.3%), but only 21 of 24 re-treated patients received a formal biopsy. No patients died from laryngeal cancer. DSS and OS were 100% and 92.3%, respectively. The mean VHI-10 scores were 19.3 preoperatively, 3.8 at 6-months postop, and 3.8 at 2-years postop. Smokers had a longer interval to re-treatment ( P = .03), patients with T2 lesions had a shorter interval to re-treatment (0.02), and patients with T2 lesions presented with worse initial VHI-10 scores (0.002). Conclusions: A multi-institutional, retrospective case series of TLM-KTP ablation of EGC demonstrated excellent oncologic outcomes when close surveillance and proactive re-treatments were utilized. Disease-specific survival, overall survival, and vocal function were excellent. Additional studies are necessary to further analyze the merits and risks of this treatment approach.

Objective There is a paucity of data regarding financial trends for procedural reimbursements in otolaryngology. The purpose of this study was to evaluate monetary trends in Medicare reimbursement rates for the 20 most commonly billed otolaryngology procedures from 2000 to 2019. Study Design Analysis of physician reimbursement. Methods The American Academy of Otolaryngology–Head and Neck Surgery database was queried to determine the 20 most performed otolaryngology procedures. Next, the Physician Fee Schedule Look‐Up Tool from the Centers for Medicare and Medicaid Services was utilized to assess each of the top 20 most utilized Current Procedural Terminology (CPT) codes in otolaryngology, and reimbursement data was extracted. All monetary data was adjusted for inflation to 2019 U.S. dollars using changes to consumer price index. Average annual and total percentage change in reimbursement were calculated based on adjusted values for all included procedures. Results After adjusting for inflation, the average reimbursement for the total 20 procedures decreased by 37.63% from 2000 to 2019. The greatest single mean decrease was seen in CPT code 61782 for stereotaxis procedures on the skull, meninges, and brain (−59.96%), whereas the smallest mean decrease was in CPT code 30520 for septoplasty (−1.50%). From 2000 to 2019, the adjusted reimbursement rate for the combined procedures decreased by an average of 2.33% each year. Conclusion Medicare reimbursement for included procedures has decreased from 2000 to 2019. Increased awareness and consideration of these trends will be important for policy makers, hospitals, and surgeons in order to assure continued access to meaningful otolaryngology care in the United States.
