Objectives/Hypothesis To identify the most influential publications in laryngology since 2000. Study Design Modified Delphi process. Methods Samples of laryngologists drawn from editors of leading journals, organization officers, and thought leaders were invited to participate in a modified Delphi identification of influential laryngology papers. Influential was defined as follows: yielding meaningful practice changes, catalyzing further work as a foundation for an important topic, altering traditional views, or demonstrating durability over time. Quality and validity were not among the selection criteria. Each participant nominated 5 to 10 papers in Round 1. These nominations, augmented with papers from bibliometric analysis, were narrowed further in Round 2 as participants identified their top 20. The 40 papers with the most Round 2 votes were discussed by video conference and then subjected to Round 3 voting, with each participant again selecting their top 20 most influential papers. Final results were collated by the number of Round 3 votes. Results Sixteen of 18 invited laryngologists participated overall (all 16 in Rounds 1 and 3; 14 in Round 2). Twenty-one papers were identified as most influential. One paper appeared on all 16 Round 3 lists; three papers with eight (50%) votes each were lasted to make the list. Eleven of these 21 focused on voice; three each related to cancer, airway, and swallowing; and one encompassed all of these clinical areas. Conclusions This list of 21 influential laryngology papers serves to focus further research, provides perspective on recent advances within the field, and is an educational resource for trainees and practicing physicians.

Objective To evaluate the feasibility and outcomes of porcine submucosal allograft (Biodesign Sinonasal Repair Graft [Cook Medical, Bloomington, IN]) in oral cavity and oropharynx reconstruction after ablative surgery. Methods We conducted a prospective and retrospective review of patients who underwent Biodesign Sinonasal Repair Graft reconstruction for oral and oropharyngeal surgical defects at a single institution between 2018 and 2020. A total of 11 patients were included in the study. Data points included their perioperative medical and demographic data, immediate postoperative course, and follow-up visits at 10 days and at 2 months. The clinicopathologic characteristics of their disease, postoperative esthetic, and functional outcomes were recorded and analyzed. Results Eleven procedures have been performed, and all patients received Biodesign reconstruction either immediately after ablation or after they failed a previous reconstruction. None of the patients had bone exposure. The subsites included oral tongue (n = 6), floor of the mouth (n = 3), buccal mucosa (n = 1), and soft palate (n = 1). In all cases, the operations and the postoperative course were uneventful. The mean defect size was 22 cm2. The median start of oral intake was at 2 days postoperatively. The Biodesign graft healed well in all patients with no total graft loss. There was one complication that required revision surgery due to obstruction of Wharton's duct by the Biodesign material. Conclusions Biodesign can be a viable option for small and medium-sized oral and oropharyngeal defects in patients who are medically unfit or do not want to undergo a free flap surgery.

Objective To describe transient and permanent hypocalcaemia following partial and total pharyngolaryngectomy with parathyroid gland preservation or autotransplantation. Methods Thirty patients underwent partial or total pharyngolaryngectomy by a single surgeon during the period 2009-2020. Intraoperative parathyroid gland preservation or autotransplantation (where the gland appeared devascularized) was routinely performed. Calcium levels performed on day 1, 3 months, and at 12 months postoperatively were collected. Rates of transient and permanent hypocalcaemia were calculated. Results A total of 13% of patients had transient hypocalcaemia, and 10% permanent hypocalcaemia. Rates of transient and permanent hypocalcaemia in total pharyngolaryngectomy were 14% and 14%, respectively. Partial pharyngectomy hypocalcaemia rates were 13% for transient and 0% for permanent. The majority of patients underwent salvage surgery for oncological resection, often following radiotherapy (63%). Ipsilateral hemithyroidectomy was preferred to total (57% vs 7%), with high rates of concurrent neck dissection (67%) and reconstruction (87%). Conclusion This data supports preservation or autotransplantation of parathyroid glands as a means of reducing permanent postoperative hypocalcaemia.

Objectives While it is acknowledged that otolaryngologists performing microlaryngeal surgery can develop musculoskeletal symptoms due to suboptimal body positioning relative to the patient, flexible laryngoscopy and awake laryngeal surgeries (ALSs) can also pose ergonomic risk. This prospective study measured the effects of posture during ergonomically good and bad positions during laryngoscopy using ergonomic analysis, skin-surface electromyography (EMG), and self-reported pain ratings. Study Design Prospective cohort study. Methods Eight participants trained in laryngoscopy assumed four ergonomically distinct standing positions (side/near, side/far, front/near, front/far) at three different heights (neutral—top of patient's head in line with examiner's shoulder, high—6 inches above neutral, and low—6 inches below neutral) in relation to a simulated patient. Participants' postures were analyzed using the validated Rapid Upper Limb Assessment (RULA, 1 [best] to 7 [worst]) tool for the 12 positions. Participants then simulated ALS for 10 minutes in a bad position (low-side-far) and a good position (neutral-front-near) with 12 EMG sensors positioned on the limbs and torso. Results The position with the worst RULA score was the side/near/high (7.0), and the best was the front/near/neutral (4.5). EMG measurements revealed significant differences between simulated surgery in the bad and good positions, with bad position eliciting an average of 206% greater EMG root-mean-squared magnitude across all sampled muscles compared to the good posture (paired t-test, df = 7, P < .01), consistent with self-reported fatigue/pain when positioned poorly. Conclusion Quantitative and qualitative measurements demonstrate the impact of surgeon posture during simulated laryngoscopy and suggest ergonomically beneficial posture that should facilitate ALSs.

Objectives Transoral laser microsurgery (TLM) is commonly utilized for early glottic cancer and offers favorable oncologic and functional outcomes. However, the survival implications of salvage therapy for recurrent or persistent disease have not been definitively characterized. Study Design Retrospective, national database cohort study. Methods Data were extracted from Veterans Health Affairs (VHA) Informatics and Computing Infrastructure (VINCI) concerning the TLM-based management of T1–T2 glottic squamous cell carcinoma patients between 2000 and 2017. Patients were characterized as either requiring TLM-only, or in cases of persistent or recurrent local disease, TLM plus change in treatment modality (radiotherapy, chemoradiotherapy, or open surgery). Predictors of overall survival (OS), cancer-specific survival (CSS), and salvage-free survival were evaluated via Cox and Fine-Gray models. Results About 553 patients (70.9% T1a, 13.4% T1b, 15.7% T2) were included, with a median follow-up time of 74.5 months. The need for non-TLM salvage increased along with more advanced disease (11.7% T1a, 29.7% T1b, 32.2% T2). Compared to patients with T1a disease, those with T1b and T2 tumors initially treated with TLM had a significantly higher probability of receiving non-TLM salvage (T1b: HR 2.70, 95% CI: 1.61–4.54; T2: HR 3.02, 95% CI: 1.88–4.84). In a multivariable model, receipt of non-TLM salvage was not a significant predictor of either OS (HR = 0.91, 95% CI: 0.62–1.33, P = .624) or CSS (HR 1.21 95% CI 0.51–2.86, P = .667). Conclusion The majority of patients with early glottic cancer that are managed with TLM do not require additional salvage therapy. When non-TLM salvage was required, there was no decrement in OS or CSS. Level of Evidence 4 Laryngoscope, 2021

Objectives/Hypothesis Human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) is a distinct clinical entity with good prognosis, unique demographics, and a trend toward treatment deintensification. Patients with this disease may opt out of recommended postoperative radiation therapy (PORT) for a variety of reasons. The aim of this paper was to examine factors that predict patient refusal of recommended PORT in HPV-associated OPSCC, and the association of refusal with overall survival. Study Design Retrospective population-based cohort study of patients in the National Cancer Database. Methods We conducted a retrospective cohort study of patients in the National Cancer Database diagnosed with OPSCC between January 2010 and December 2015. We primarily assessed overall survival and the odds of refusing PORT based on demographic, socioeconomic, and clinical factors. Analysis was conducted using multivariable logistic regression and multivariable Cox proportional hazards model. Results A total of 4229 patients were included in the final analysis, with 156 (3.7%) patients opting out of recommended PORT. On multivariable analysis, patient refusal of PORT was independently associated with a variety of socioeconomic factors such as race, insurance status, comorbidity, treatment at a single facility, and margin status. Lastly, PORT refusal was associated with significantly lower overall survival compared to receipt of recommended PORT (hazard ratio 1.69, confidence interval 1.02–2.82). Conclusions Patient refusal of recommended PORT in HPV-associated OPSCC is rare and associated with variety of disease and socioeconomic factors. PORT refusal may decrease overall survival in this population. Our findings may help clinicians when counseling patients and identifying those who may be more likely to opt out of recommended adjuvant therapy. Level of Evidence 3 Laryngoscope, 2021
