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.

Introduction There is currently a lack of available data clearly addressing whether the proportion of young patients diagnosed with head and neck cancer (HNC) within the U.S. has increased over the last several decades in comparison to other age cohorts. This study attempts to elucidate any trends in oral cavity, oropharynx, larynx and hypopharynx cancer age distribution in the United States population from 1975-2016. Unlike previous studies, this paper does not track incidence, but rather reports proportional changes of prevalence within age cohorts over time. Methods This is a retrospective chart review centered on data from the Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute (NCI). Each decade interval from 1975-2016 displays the proportion of HNC patients, classified by primary tumor subsite, within each age cohort. Results Mean age at diagnosis increased for three of the four HNC evaluated. Oropharyngeal cancer was the only subsite to demonstrate an overall proportional increase, mainly in middle age (40-59 years) patients. Cancers of the oral cavity were the only subset to show a true increase in the proportion of young (0-39 years) patients. When stratifying by gender, the proportion of young patients in female HNC cases is higher than the proportion of young male HNC cases. Conclusion Overall, this study demonstrates an increased proportion of older HNC patients that is consistent with the aging population. Oral cavity is the only cancer to demonstrate a true increase in the proportion of young patients, likely from the increased incidence of young women diagnosed with this cancer. Case reports citing more young patients becoming diagnosed with other types of HNC are not currently supported by the data. Lastly, the increased proportion of middle-age patients with oropharyngeal cancer likely reflects the increase in HPV-related cancers.

Objectives/HypothesisTo evaluate whether antithrombotic status impacts the incidence of perioperative or postoperative bleeding in direct microlaryngoscopy (DML).Study DesignRetrospective chart review.MethodsPatients undergoing DML in a single surgeon's practice from September 2012 to September 2017 were studied. Included patients underwent DML with or without biopsy, balloon dilation, microsurgery, laser ablation, or vocal fold injection. Patients were stratified based on perioperative antithrombotic status and assessed for rates of peri‐ and postoperative bleeding and other complications.ResultsOf the 581 patients meeting inclusion criteria, 179 patients (31%) had a history of baseline antithrombotic therapy. Of these patients, 124 had perioperative continuation of their therapy. Medicated patients were older (P < .01), predominately male (P < .01), and increasingly comorbid (P < .01). Perioperative complications unrelated to bleeding occurred in 22 patients (4%), minor perioperative bleeding occurred in four patients (0.7%), and minor postoperative bleeding occurred in 12 of the 479 patients with recorded follow‐up (2.5%). There were no postoperative bleeds requiring intervention or readmission, and no recorded thrombotic events during the peri‐ and postoperative period. There was no difference in perioperative bleeding based on baseline antithrombotic status (P = .81). Patients on baseline antithrombotic therapy were more likely to have a postoperative bleed in comparison to patients without history of antithrombotic use (P < .01). However, there were no significant differences in postoperative bleeding between patients on baseline anticoagulation who continued or ceased their medication perioperatively (P = .45).ConclusionsPerioperative continuation of antithrombotic medications appears to be safe when performing routine DML.Level of Evidence4 Laryngoscope, 2020

Objective: To review pregnancy outcomes and the safety of jet ventilation use in the gravid patient undergoing surgical airway intervention. Methods: A multi-institutional retrospective review of medical records was performed to identify women who underwent low-frequency jet ventilation during pregnancy for surgical treatment of airway stenosis. Postoperative complications were noted, and patients were interviewed regarding pregnancy outcomes. Results: Six women were included in this series. No immediate complications relating to anesthesia or surgical intervention were noted in five of the six women. One patient with a well-known history of uncontrolled seizures experienced seizure activity postoperatively. One patient returned to the operating room at a later date for debridement of tracheal crusts. Five mothers delivered via cesarean section and one via spontaneous vaginal delivery. The mean gestation age was 37.3 weeks. One of the six infants delivered prematurely and three were delivered at low birth weight. Three of the six infants required elevated care immediately post-delivery but, at present, all are in good health. Conclusion: Low-frequency jet ventilation and surgical management of airway stenosis should be recognized as a safe treatment option in the gravid patient. Surgical intervention should not be delayed in patients with severe symptoms, particularly given the potential risk associated with prolonged corticosteroid use. Level of evidence: 4

Introduction: The ability to treat more advanced laryngeal cancers by transoral approaches has expanded significantly in the past several decades. Transoral management of laryngeal cancers that require removal of the laryngeal framework is controversial. Resecting cartilage through endoscopic means carries inherent technical challenges and the question of oncologic safety. Methods: We describe a retrospective review of patients undergoing resection of the thyroid cartilage during transoral laser microsurgery (TLM) for laryngeal cancer over a 10-year period. Only patients with 5-year follow-up were included. Results: Fourteen patients were identified that underwent attempted endoscopic resection of the thyroid cartilage. Preoperative staging ranged from T1 to T4 laryngeal cancers. Most patients underwent resection of the thyroid cartilage either for close proximity of the tumor to cartilage or microscopic involvement of the inner perichondrium, although 6 patients had gross invasion of the cartilage. Twelve patients underwent successful endoscopic clearance. Two patients were converted to total laryngectomy either at the time of surgery or shortly after due to extent of disease that was deemed not amenable to endoscopic resection. Overall 5-year survival was 71%. Disease-free survival was 62% at 5 years. The majority of patients avoided gastrostomy and tracheostomy tube dependence. One patient underwent total laryngectomy following initial TLM for chronic aspiration. Conclusion: We conclude that TLM for laryngeal cancer performed with removal of thyroid cartilage is feasible. Both oncologic and functional outcomes are reasonable in a select group of patients. This paper describes that cartilage can be resected endoscopically in the appropriate setting and not necessarily that cartilage invasion should routinely be treated with TLM.

ObjectiveThe study aims to demonstrate the reproducibility and feasibility of creating a hemilaryngeal model with a medialized vocal fold (VF) using 3‐dimensional (3D) modeling techniques in both healthy larynges and those affected by cancer.Study DesignThree‐dimensional modeling of human larynges.SettingTertiary academic referral center and regenerative medicine laboratory.Subjects and MethodsComputed tomography (CT) scans from 10 healthy control and 10 patients with laryngeal cancer were segmented and imported into 3D modeling software. The larynx was cut sagittally to create a hemilaryngeal model and the vocal fold medialized. Measurements were taken from the CT and 3D model data and compared.ResultsAll control modeling data closely matched the CT data and were not statistically different from each other. There was a significant correlation between subglottic anteroposterior diameter and VF length (r2 = 0.78, P =. 0008), and it may be a valuable tool to infer true VF dimension in cases where disruption has occurred. The modeling data from patients with cancer did not show statistical difference to the control data, showing that accurate modeling can also be achieved in patients with laryngeal cancer.ConclusionCT scan‐based 3D modeling of the larynx and VF is possible and reproducible. The results closely match those previously reported in the literature and can also be replicated in cases with laryngeal cancer. This study paves the way for future de novo fabricated laryngeal scaffolds that can be synthesized using 3D printers and tailored to meet surgical demands.
