Objectives/Hypothesis Balloon sinuplasty has become an increasingly popular option for patients undergoing surgical treatment of sinusitis. This study analyzes utilization and growth of these procedures across a large cohort of patients over a 5‐year period. Study Design Retrospective data review. Methods This was a retrospective review of Medicare utilization and billing data. Utilization and payment values were obtained from Medicare claims data using Centers for Medicare and Medicaid Services datasets. All Medicare claims were analyzed from 2012 to 2016. Data were extracted for balloon sinuplasty and endoscopic sinus surgery claims. Procedure location, total submitted claims, charges, and payments were compared. Results From 2012 to 2016, the number of balloon procedures increased from 5,603 to 25,640. Traditional endoscopic sinus surgery procedures increased from 15,509 to 18,164. Aggregate Medicare payments to otolaryngologists for endoscopic sinus surgery have remained relatively stable, whereas there has been a 450% increase in total payments to providers of balloon sinuplasty. In 2016, total payments to providers of balloon procedures ($40.5 million) were substantially higher than payments to providers of non–balloon‐based endoscopic sinus surgery ($4.7 million). The number of providers performing balloon procedures has increased 277% versus 17% for traditional sinus surgery. Conclusions There has been a rapid expansion in the number of sinus procedures in the Medicare population from 2012 to 2016. Office‐based balloon procedures account for the overwhelming majority of the increases in procedures and payments. Per procedure and aggregate payments are now higher for sinuplasty procedures than for traditional sinus surgery. Level of Evidence NA Laryngoscope, 129:2224–2229, 2019
Objective: During the COVID-19 era, a reliable method for tracing aerosols and droplets generated during otolaryngology procedures is needed to accurately assess contamination risk and to develop mitigation measures. Prior studies have not investigated the reliability of different fluorescent tracers for the purpose of studying aerosols and small droplets. Objectives include (1) comparing vitamin B2, fluorescein, and a commercial fluorescent green dye in terms of particle dispersion pattern, suspension into aerosols and small droplets, and fluorescence in aerosolized form and (2) determining the utility of vitamin B2 as a fluorescent tracer coating the aerodigestive tract mucosa in otolaryngology contamination models. Methods: Vitamin B2, fluorescein, and a commercial fluorescent dye were aerosolized using a nebulizer and passed through the nasal cavity from the trachea in a retrograde-intubated cadaveric head. In another scenario, vitamin B2 was irrigated to coat the nasal cavity and nasopharyngeal mucosa of a cadaveric head for assessment of aerosol and droplet generation from endonasal drilling. A cascade impactor was used to collect aerosols and small droplets ≤14.1 µm based on average aerodynamic diameter, and the collection chambers were visualized under UV light. Results: When vitamin B2 was nebulized, aerosols ≤5.4 µm were generated and the collected particles were fluorescent. When fluorescein and the commercial water tracer dye were nebulized, aerosols ≤8.61 µm and ≤2.08 µm respectively were generated, but the collected aerosols did not appear visibly fluorescent. Endonasal drilling in the nasopharynx coated with vitamin B2 irrigation yielded aerosols ≤3.30 µm that were fluorescent under UV light. Conclusion: Vitamin B2’s reliability as a fluorescent tracer when suspended in aerosols and small droplets ≤14.1 µm and known mucosal safety profile make it an ideal compound compared to fluorescein and commercial water-based fluorescent dyes for use as a safe fluorescent tracer in healthcare contamination models especially with human subjects.
Objectives/Hypothesis We have seen several incidences of catastrophic bleeding in patients with advanced oropharyngeal squamous cell carcinoma treated nonoperatively. Aside from advanced disease, these patients have not had traditional risk factors for major hemorrhage. Study Design Retrospective chart review. Methods Patients treated nonoperatively for oropharyngeal squamous cell carcinoma were compared to determine characteristics that may predisposed to bleeding. Five patients with bleeding were identified and compared with a cohort of stage‐ and treatment‐matched patients without bleeding. Blinded imaging review was performed to characterize the tumor site and its relationship to vasculature using standardized systems. Results Comparing the bleeder versus nonbleeder groups pre‐treatment, the bleeder group had larger tumors (15.4 vs. 8.3 cm2), greater rates of parapharyngeal fat effacement (80% vs. 20%), and always involved the facial artery. Post‐treatment, endophytic ulcerated tumor beds occurred in 100% of bleeders versus 0% of nonbleeders. Conclusions Catastrophic oropharyngeal bleeding may be encountered after cytoreductive therapy. Large deeply invasive tumors seem to set the necessary circumstances. Rapid vascular control with interventional radiology has been largely effective therapy.

Objective: The American Joint Committee on Cancer (AJCC) 8th edition introduced distinct clinical and pathological staging paradigms for human papilloma virus positive (HPV+) oropharyngeal squamous cell carcinoma (OPSCC). Treatment planning for OPSCC often utilizes positron emission tomography/computed tomography (PET/CT) to assess clinical stage. We hypothesize that PET/CT will accurately predict final pathologic AJCC 8th edition staging in patients with HPV+ OPSCC.Methods: All patients with primary HPV+ OPSCC with preoperative PET/CT who underwent transoral robotic surgery and neck dissection between 2011 and 2017 were identified. Data were collected via chart review. Two neuroradiologists performed blinded re-evaluation of all scans. Primary tumor size and cervical nodal disease characteristics were recorded and TNM staging was extrapolated. Cohen's kappa statistic was used to assess interrater reliability. Test for symmetry was performed to analyze discordance between radiologic and pathologic staging.Results: Forty-nine patients met inclusion criteria. Interrater reliability was substantial between radiologists for nodal (N) and overall staging (OS) (κ = 0.715 and 0.715). Radiologist A review resulted in identical OS for 67% of patients, overstaging for 31%, and understaging for 2%. Radiologist B review resulted in 61% identical OS, 39% overstaging, and 0% understaging. In misclassified cases, the test of symmetry shows strong bias toward overstaging N stage and OS (P < .001). Radiologic interpretation of extracapsular extension showed poor interrater reliability (κ = 0.403) and poor accuracy.Conclusion: PET/CT predicts a higher nodal and overall stage than pathologic staging. PET/CT should not be relied upon for initial tumor staging, as increased FDG uptake is not specific for nodal metastases. PET/CT is shown to be a poor predictor of ECE.
Objectives: Define aerosol and droplet risks associated with routine otolaryngology clinic procedures during the COVID-19 era. Methods: Clinical procedures were simulated in cadaveric heads whose oral and nasal cavities were coated with fluorescent tracer (vitamin B2) and breathing was manually simulated through retrograde intubation. A cascade impactor placed adjacent to the nares collected generated particles with aerodynamic diameters ≤14.1 µm. The 3D printed models and syringes were used to simulate middle and external ear suctioning as well as open suctioning, respectively. Provider’s personal protective equipment (PPE) and procedural field contamination were also recorded for all trials using vitamin B2 fluorescent tracer. Results: The positive controls of nebulized vitamin B2 produced aerosol particles ≤3.30 µm and endonasal drilling of a 3D model generated particles ≤14.1 µm. As compared with positive controls, aerosols and small droplets with aerodynamic diameter ≤14.1 µm were not detected during rigid nasal endoscopy, flexible fiberoptic laryngoscopy, and rigid nasal suction of cadavers with simulated breathing. There was minimal to no field contamination in all 3 scenarios. Middle and external ear suctioning and open container suctioning did not result in any detectable droplet contamination. The clinic suction unit contained all fluorescent material without surrounding environmental contamination. Conclusion: While patients’ coughing and sneezing may create a baseline risk for providers, this study demonstrates that nasal endoscopy, flexible laryngoscopy, and suctioning inherently do not pose an additional risk in terms of aerosol and small droplet generation. An overarching generalization cannot be made about endoscopy or suctioning being an aerosol generating procedure. Level of Evidence: 3
