Abstract
PURPOSE To compare human papillomavirus (HPV) testing, prevalence, and association with prognosis between head and neck squamous cell carcinoma (HNSCC) subsites. MATERIALS AND METHODS This study utilized the National Cancer Database (NCDB) to identify patients diagnosed with HNSCC between 2010 and 2017. Rates of HPV testing, HPV-positivity, and changes in these rates over time were measured by subsite. The impact of HPV-positivity on overall survival across six head and neck subsites was assessed using multivariable-adjusted Cox proportional hazards analysis. RESULTS A total of 121,550 patients were included. Of this cohort, 87,575 (72.1%) were tested for HPV, with the oropharynx (55,049/64,158; 85.8%) displaying the highest rates of testing and the sinonasal tract (1519/2853; 53.2%) displaying the lowest testing rates. Of the 86,136 with a definitive result, 46,878 (54.4%) were HPV-positive, with the oropharynx (40,313/54,205; 74.4%) displaying the highest rates of HPV-positivity and the oral cavity (1818/11,505; 15.8%) displaying the lowest. HPV-positive malignancy was associated with significantly improved adjusted overall survival in the oropharynx (HR = 0.42 [95% CI: 0.43-0.47]), oral cavity (HR = 0.86 [95% CI: 0.79-0.95]), sinonasal tract (HR = 0.63 [95% CI: 0.48-0.83]), larynx (HR = 0.78 [95% CI: 0.71-0.87]), and hypopharynx (HR = 0.56 [95% CI: 0.48-0.66]), but not the nasopharynx (HR = 0.93 [95% CI: 0.77-1.14]). CONCLUSION HPV testing rates were significantly lower in non-oropharyngeal subsites. This is relevant as HPV-associated disease displayed significantly improved overall survival in both the oropharynx and four of five non-oropharyngeal subsites. While validation with prospective studies is necessary, these findings may warrant HPV testing in all HNSCC subsites.

Abstract
Importance There is growing interest in the use of circulating plasma tumor human papillomavirus (HPV) DNA for diagnosis and surveillance of patients with HPV-associated oropharyngeal squamous cell carcinoma (OPSCC). Recent advances in the assays, combining the identification of circulating HPV tumor DNA and tumor DNA fragment analysis (tumor tissue-modified viral [TTMV]-HPV DNA), have been shown to be highly accurate. However, use of these newer techniques has been limited to small cohort studies and clinical trials. Objective To establish the clinical efficacy of plasma TTMV-HPV DNA testing in the diagnosis and surveillance of HPV-associated OPSCC in a contemporary clinical setting. Design, Setting, and Participants This retrospective observational cohort study included patients with OPSCC who underwent TTMV-HPV DNA testing between April 2020 and September 2022 during the course of routine clinical care. For the diagnosis cohort, patients with at least 1 TTMV-HPV DNA measurement prior to initiation of primary therapy were included. Patients were included in the surveillance cohort if they had at least 1 TTMV-HPV DNA test performed after completion of definitive or salvage therapy. Main Outcomes and Measures Per-test performance metrics, including sensitivity, specificity, positive predictive value, and negative predictive value, for TTMV-HPV DNA testing. Results Of 399 patients included in the analysis, 163 were in the diagnostic cohort (median [IQR] age, 63 [56-68.5] years; 142 [87.1%] male), and 290 were in the surveillance cohort (median [IQR] age, 63 [57-70] years; 237 [81.7%] male). Of the 163 patients in the diagnostic cohort, 152 (93.3%) had HPV-associated OPSCC while 11 (6.7%) had HPV-negative OPSCC. The TTMV-HPV DNA sensitivity in pretreatment diagnosis was 91.5% (95% CI, 85.8%-95.4% [139 of 152 tests]), and the specificity was 100% (95% CI, 71.5%-100% [11 of 11 tests]). In the surveillance cohort, 591 tests conducted in 290 patients were evaluated. A total of 23 patients had molecularly confirmed pathologic recurrences. The TTMV-HPV DNA test demonstrated sensitivity of 88.4% (95% CI, 74.9%-96.1% [38 of 43 tests]) and specificity of 100% (95% CI, 99.3%-100% [548 of 548 tests]) in detecting the recurrences. Positive predictive value was 100% (95% CI, 90.7%-100% [38 of 38 tests]), and negative predictive value was 99.1% (95% CI, 97.9%-99.7% [548 of 553 tests]). The median (range) lead time from positive TTMV-HPV DNA test to pathologic confirmation was 47 (0-507) days. Conclusions and Relevance This cohort study demonstrated that when evaluated in a clinical setting, the TTMV-HPV DNA assay demonstrated 100% specificity in both diagnosis and surveillance. However, the sensitivity was 91.5% for the diagnosis cohort and 88.4% for the surveillance cohort, signifying that nearly 1 in 10 negative tests among patients with HPV-associated OPSCC was a false negative. Additional research is required to validate the assay's performance and, if validated, then further research into the implementation of this assay into standard clinical practice guidelines will be required.

Abstract
BACKGROUND Neutrophil-to-lymphocyte ratio (NLR) is a biomarker of systemic inflammation that is associated with adverse oncologic and surgical outcomes. We investigated the use of NLR as a prognostic indicator of complications of head and neck cancer (HNC) surgeries. METHODS We conducted a retrospective study of 11 187 Veterans who underwent HNC surgery between 2000 and 2020. We calculated preoperative NLR values and fit logistic regression models adjusting for potential confounding factors, comparing high-NLR patients to low-NLR patients. RESULTS The cohort had a median age of 63 and was 98% men. High-NLR patients had increased odds of 30-day mortality (p < 0.001), having 1+ perioperative complications (p < 0.001), sepsis (p = 0.03), failure to wean from mechanical ventilation (p = 0.04), pneumonia (p < 0.001), and pulmonary embolism (p = 0.02) compared with low-NLR patients. CONCLUSION NLR was a robust, independent predictor of 30-day mortality, having 1+ surgical complications, sepsis, failure to wean from mechanical ventilation, pneumonia, and pulmonary embolism.

Abstract
Abstract
Purpose: Despite favorable outcomes, up to 20% of patients with human papillomavirus (HPV)-driven oropharyngeal squamous cell carcinoma (OPSCC) will experience recurrence. Monitoring circulating tumor tissue modified viral (TTMV)-HPV DNA during post-treatment surveillance has emerged as a tool that has demonstrated >95% positive predictive value (PPV) for detecting recurrence. Here we describe a large real-world population with detailed clinical follow-up, permitting determination of the longitudinal negative predictive value (NPV) of the assay.
Patients and methods: This IRB-approved, retrospective observational cohort study included 312 patients across five U.S. centers who were ≥3 months post-treatment for HPV-driven OPSCC. Patients had one or more TTMV-HPV DNA results (NavDx®, Naveris Laboratories) obtained during surveillance between February 2020 and January 2021. A baseline TTMV-HPV DNA test was not required. HPV status was assessed by p16 immunohistochemistry or HPV PCR/ISH. Test results were correlated with physician-reported exam and imaging findings to assess disease status in follow-up.
Results: The cohort was mostly male (85%), had a median age of 61 (range: 27-81), included smokers (50%), and 282 (90%) had involved nodes (N1: 204, N2: 70, N3: 8) at initial staging. Curative-intent treatment involved surgery with or without another modality in 54% of cases (169/312). Median follow-up time was 23.5 months, and 39 patients (12.5%) had documented recurrence. Most patients had >1 TTMV-HPV DNA test result ≥3 months post-treatment (231, 74%), with 48 (15%) having 5 or more tests. Among patients with multiple negative surveillance tests, the median time between tests was 126 days (4.2 months, range: 0.37-24.2). The first TTMV-HPV DNA surveillance test was most often performed within the first year post-treatment (195, 63%). Across 812 test results, the NPV was 99.5%. There were 4 false negative tests among patients with confirmed p16-positive (3/4) or HPV PCR-positive (1/4) biopsy-proven recurrence. One of these patients had a subsequent positive TTMV-HPV DNA test during salvage immunotherapy. Only one of these patients had baseline TTMV-HPV DNA testing available, which showed a low positive <50 TTMV-HPV16 DNA Score, whereas the other three patients did not have a baseline result available.
Conclusion: Our findings further support the clinical potential of monitoring circulating TTMV-HPV DNA during post-treatment surveillance. We demonstrate a very high assay NPV correlated with physician-reported outcomes. TTMV-HPV DNA can be used to assist in surveillance and could inform imaging needs and future practice guidelines for HPV-driven head and neck cancer survivors.

Abstract
BACKGROUND Percutaneous endoscopic gastronomy (PEG) tubes are commonly used to administer enteral nutrition during head and neck cancer (HNC) treatment. However, the benefits of placing a prophylactic feeding tube (PFT; prior to radiotherapy [RT]) or reactive feeding tube (RFT, after RT initiation) are unclear. We sought to compare survival, body mass trends, and hospitalization rates between strategies. METHODS We conducted a retrospective cohort study of 11,473 Veterans with stages III-IVC HNC treated with chemoradiotherapy. Patients with PEG tube placement within 30 days prior to treatment initiation (PFT) were compared to all other patients (non-PFT) or patients with PEG tube placement within 3 months after treatment initiation placement (RFT). We compared survival, longitudinal body mass changes, and hospitalization rates for PFT versus non-PFT or RFT patients in propensity score (PS)-matched Cox regression models. RESULTS 3,186 (28 %) patients received PFT and 8,287 (72 %) were non-PFT, of which 1,874 (23 %) received RFT. After PS-matching, there were no significant differences in overall survival (HR 0.97, 95 % CI 0.92-1.02), HNC-specific survival (HR 0.98, 95 % CI 0.92-1.09), change in BMI (p = 0.24), or hospitalization rates between PFT and non-PFT groups. Significant differences in hospitalization rates between PFT and RFT groups persisted after PS-matching (-0.11 hospitalizations/month), but no differences were found for other outcomes. CONCLUSION Timing of PEG tube placement in Veterans with HNC was not associated with any significant survival or body mass advantage. However, patients who received PFT had a lower hospitalization rate than those who received RFT.

Abstract
Background Human papillomavirus associated oropharyngeal squamous cell carcinoma (HPVOPSCC) usually affects a younger patient population. As such, the risk for long term toxicity associated with therapy is an important consideration. Multiple trials focused on de-escalation of therapy to preserve survival outcomes while minimizing treatment toxicity are currently in progress, however the question of which patients are ideal candidates for de-escalation remains unanswered. Circulating tumor DNA (cfHPVDNA) has emerged as a means of monitoring disease in patients with HPVOPSCC. Undetectable postoperative cfHPVDNA levels portend a better prognosis and by extension, may identify ideal candidates for de-escalation therapy. We propose an overview and rationale for a new institutional clinical trial protocol focusing on the use of cfHPVDNA to risk stratify patients for adjuvant therapy. We hypothesize that many surgical patients currently receiving radiation therapy may be clinically observed without adjuvant therapy. Methods Patients with measurable cfHPVDNA and clinically resectable HPVOPSCC will undergo TORS resection of tumors and neck dissection. Patients with undetectable cfHPVDNA at 3 weeks post-op will be allocated to low or high-risk treatment protocol groups. The low risk group consists of patients with <4 positive lymph nodes, ≤2 mm extranodal extension (ENE), and perineural invasion (PNI) or lymphovascular invasion (LVI) alone. The high-risk group is made up of patients with ≥4 positive lymph nodes, gross ENE, positive margins, N2c disease and/or the combination of both PNI and LVI. The low-risk group will be allocated to an observation arm, while the high-risk group will receive 46 Gy of adjuvant radiotherapy and weekly cisplatin therapy. The primary outcome of interest is 2-year disease recurrence with secondary outcomes of 2-year disease free survival, locoregional control, overall survival, and quality of life measures. A sample of 126 patients in the low-risk group and 73 patients in the high-risk group will be required to evaluate non-inferiority to the standard of care. Discussion This study will provide much needed recurrence and survival data for patients that undergo primary TORS followed by observation or de-escalated adjuvant therapy. Additionally, it will help delineate the role of cfHPVDNA in the risk stratification of patients that undergo treatment de-intensification.

Our objectives included assessment of practice patterns and outcomes. METHODS Multi-institutional, retrospective review of FF reconstruction for head and neck osteoradionecrosis (n = 260). RESULTS Administration of preoperative antibiotics did not correlate with reduction in postoperative complications. Preoperative alcohol use correlated with higher rates of hardware exposure (p = 0.03) and 30-day readmission (p = 0.04). Patients with FF compromise had higher TSH (p = 0.04) and lower albumin levels (p = 0.005). Prealbumin levels were lower in patients who required neck washouts (p = 0.02) or a second FF (p = 0.03). TSH levels were higher in patients undergoing postoperative debridement (p = 0.03) or local flap procedures (p = 0.04). CONCLUSION Malnutrition, hypothyroidism, and substance abuse correlated with a higher incidence of postoperative wound complications in patients undergoing FF reconstruction for advanced osteoradionecrosis. Preoperative antibiotics use did not correlate with a reduction in postoperative wound complications.

Abstract
BACKGROUND Salivary fistulas remain a significant problem in patients undergoing major head and neck reconstructive surgery. Surgical sealants have become increasingly used in cutaneous and non-cutaneous wound closure, providing a barrier to fluids/gases and promoting healing. The purpose of this study was to determine the efficacy of a common surgical sealant, 2-Octyl Cyanoacrylate (2-OCA, Dermabond®), in the prevention of salivary fistulas following free flap reconstruction of the oral cavity. METHODS In this non-randomized, single arm prospective trial, patients undergoing free flap reconstruction of gravity-dependent oral cavity defects were recruited. Application of 2-OCA was performed along flap inset suture lines at the time of surgery. Prospectively collected trial data were propensity score matched to a control cohort to compare outcomes. Data collected include demographics, medical co-morbidities, previous treatments, primary tumor site, and subsites reconstructed. The primary outcome measure was rate of salivary fistula formation. Secondary outcomes were time to development of leak and percentage of patients tolerating oral feeding at one month post-operatively. RESULTS In the 46 propensity score matched pairs, eight (17.4%) out of 46 patients in the 2-OCA prospective cohort and seven (15.2%) out of 46 patients in the control cohort developed postoperative salivary fistulas within the one-month study interval (p = 1.00). The average time to postoperative leak in the 2-OCA group was 12.5 days versus 7.1 days in the control cohort (p = 0.10). In the 2-OCA group, 30 (65.2%) patients were tolerating regular diet at one month post-operatively compared to 33 (71.7%) in the control cohort (p = 0.65). CONCLUSION Salivary fistula rates after application of a 2-OCA surgical sealant were not improved compared to a control cohort in this single institutional trial. There are several surgical sealants available, each with varying elasticity and adhesiveness. Future studies are needed to identify surgical sealants that are able to provide sufficient strength and adhesion to seal closures and combat corrosive saliva, but elastic enough to handle motion related tension during swallowing and post-operative movements in the head and neck.

Abstract
BACKGROUND Neutrophil-to-lymphocyte ratio (NLR) is a biomarker that is correlated with systemic inflammation and poor prognosis in solid tumors. We investigated the value of NLR in predicting survival in a large population of head and neck cancer patients in the United States. METHODS We performed a retrospective cohort study of Veterans Affairs patients with head and neck squamous cell carcinoma (HNSCC) diagnosed between January 2000 and December 2017. We compared 5-year overall survival and cancer-specific survival for different NLR tertiles using cox proportional hazards modeling with adjustment for covariates. RESULTS The primary cohort consisted of 14 644 subjects of which 99% were male. Relative to patients with NLRs in the lower tertile, patients with NLRs in the top tertile had an 71% increased hazard of all-cause mortality (P < .001) and 44% increased hazard of cancer-specific mortality (P < .001) at 5 years. CONCLUSIONS Elevated NLR in HNSCC confers a poor prognosis.

Abstract
OBJECTIVE Although it is known that the airway has bacterial contamination that seeds the surgical site during microlaryngeal surgery, literature on the use of postoperative antibiotics is lacking. We performed a retrospective analysis of open phonosurgical and phonomicrosurgical cases at a single institution to assess whether use of postoperative antibiotics impacts the incidence of surgical site infections (SSI). METHODS In this retrospective cohort study, we reviewed 228 phonomicrosurgery and 53 open phonosurgery cases performed for benign diseases. Surgeries were performed by two laryngologists between February 2016 and August 2018. The surgeons differ in their postoperative antibiotic regimens: no antibiotics versus a 5- to 7-day postoperative course. Data collected include demographics, medical comorbidities, type of benign laryngeal disease, and surgical procedure. The primary outcome measure was postoperative infection, defined as the patient requiring a new prescription for antibiotics, an extended course of antibiotics, or any mention of infection at follow-up/emergency visits within the first month postoperatively. RESULTS The overall rate of SSI was 3.1% and 0% for phonomicrosurgery and open phonosurgery cases, respectively. For phonomicrosurgery, there was no difference in the rate of SSI for patients who received or did not receive antibiotics perioperatively: 2.9% versus 3.2% (P = 0.99). Similarly, there was no difference in the infection rate for open phonosurgical cases. CONCLUSION Infection rates after endoscopic and open phonosurgery are low. In this study, we found no evidence to suggest a protective effect associated with postoperative use of antibiotics. LEVEL OF EVIDENCE 4 Laryngoscope, 130:1128-1131, 2020.

Abstract
Ankle fractures are common orthopedic injuries with favorable outcomes when managed with open reduction and internal fixation (ORIF). Several patient-related risk factors may contribute to poor short-term outcomes, and machine learning may be a valuable tool for predicting outcomes. The objective of this study was to evaluate machine-learning algorithms for accurately predicting short-term outcomes after ORIF for ankle fractures. The Nationwide Inpatient Sample and Nationwide Readmissions Database were queried for adult patients ≥18 years old who underwent ORIF of an ankle fracture during 2013 or 2014. Morbidity and mortality, length of stay >3 days, and 30-day all-cause readmission were the outcomes of interest. Two machine-learning models were created to identify patient and hospital characteristics associated with the 3 outcomes. The machine learning models were evaluated using confusion matrices and receiver operating characteristic area under the curve values. A total of 16,501 cases were drawn from the Nationwide Inpatient Sample and used to assess morbidity and mortality and length of stay >3 days, and 33,504 cases were drawn from the Nationwide Readmissions Database to assess 30-day readmission. Older age, Medicaid, Medicare, deficiency anemia, congestive heart failure, chronic lung disease, diabetes, hypertension, and renal failure were the variables associated with a statistically significant increased risk of developing all 3 adverse events. Logistic regression and gradient boosting had similar area under the curve values for each outcome, but gradient boosting was more accurate and more specific for predicting each outcome. Our results suggest that several comorbidities may be associated with adverse short-term outcomes after ORIF of ankle fractures, and that machine learning can accurately predict these outcomes.

Abstract
IMPORTANCE: Otolaryngology residents take the otolaryngology training examination (OTE) yearly to assess their fund of knowledge. The Accreditation Council for Graduate Medical Education (ACGME) milestone evaluations are also conducted semiannually. Accurate prediction of training examination performance allows identification of residents who are performing well and those who need targeted remediation. Prior studies in other specialties have attempted to use milestone evaluations to help predict in-training examination scores. OBJECTIVE: In this study, we aim to identify whether ACGME milestone evaluation scores predict OTE performance. DESIGN: Milestone ratings and OTE scores for residents at 2 US otolaryngology residency programs were collected. Multivariate analysis was achieved using linear mixed modeling. We considered a 2-tailed P value of ≤ .05 as statistically significant. SETTING: Two US otolaryngology residency programs. PARTICIPANTS: Forty-eight otolaryngology residents postgraduate years 2 to 5. RESULTS: Otolaryngology training examination scores and ACGME milestone evaluations were collected from 48 residents from postgraduate year 2 to 5 between the years 2014 and 2017. One hundred eight OTE scores were available. Linear mixed-effect models were constructed, and after adjusting for level of training and OTE year, the total milestone rating made a negligible impact in estimating OTE percentage correct (β = -.01, P = .9). Similarly, total milestone rating demonstrated a minimal contribution in approximating OTE national stanine score after adjusting for the level of training (β = -.003, P = .9). CONCLUSIONS AND RELEVANCE: In our study, ACGME milestone evaluations are not predictive of residents' OTE performance. What these milestone evaluation data mean and how they should be used continues to be an unanswered question. We should aim to identify the most effective applications of the milestone data collected yearly by otolaryngology programs.

Abstract
Rigid flatfoot deformity is a debilitating condition that can be managed by triple arthrodesis surgery. Triple arthrodesis has the potential to restore health-related quality of life, but it is also associated with several complications. Few studies have examined the 30-day readmission rates after triple arthrodesis. The objective of this study was to investigate risk factors for 30-day all-cause readmissions after triple arthrodesis. The nationwide readmission database was queried from 2013. By using International Classification of Disease, Ninth Revision, procedure codes, all triple arthrodesis procedures were identified. Demographic factors, comorbidities, insurance status, and hospital characteristics were statistically compared between patients who experienced a 30-day readmission and those who did not. Multivariable logistic regression was used to identify independent risk factors for 30-day readmission. Overall, 1916 triple arthrodesis cases were identified. The overall 30-day readmission rate after triple arthrodesis was 4.6%. Univariate analysis revealed a statistically higher proportion of patients with electrolyte abnormalities (13.8% vs 4.6%; p < .01) in the patients who were readmitted within 30 days compared with those who were not. Multivariable analysis demonstrated Medicaid insurance, relative to private insurance, as the only statistically significant predictor of 30-day readmission with an odds ratio of 4.43 (p < .05). These results suggest that patients of lower socioeconomic status may be at a greater risk for development of a short-term readmission after triple arthrodesis surgery. These findings are important for surgeon and patient communication, counseling, and postoperative care when choosing to pursue triple arthrodesis surgery.
