Reconstruction for Salvage Laryngectomy With Limited Pharyngectomy.

Importance: Closure technique for optimization of postoperative and functional outcomes following salvage laryngectomy remains an area of debate among head and neck surgeons. Objective: To investigate the association of salvage laryngectomy closure technique with early postoperative and functional outcomes. Design, Setting, and Participants: This retrospective cohort study included patients from 17 academic, tertiary care centers who underwent total laryngectomy with no or limited pharyngectomy after completing a course of definitive radiotherapy or chemoradiotherapy with curative intent between January 2011 and December 2016. Patients with defects not amenable to primary closure were excluded. Data were analyzed from February 14, 2021, to January 29, 2024. Exposures: Total laryngectomy with and without limited pharyngectomy, reconstructed by primary mucosal closure (PC), regional closure (RC), or free tissue transfer (FTT). Main Outcomes and Measures: Patients were stratified on the basis of the pharyngeal closure technique. Perioperative and long-term functional outcomes were evaluated with bivariate analyses. A multivariable regression model adjusted for historical risk factors for pharyngocutaneous fistula (PCF) was used to assess risk associated with closure technique. Relative risks (RRs) with 95% CIs were determined. Results: The study included 309 patients (256 [82.8%] male; mean age, 64.7 [range, 58.0-72.0] years). Defects were reconstructed as follows: FTT (161 patients [52.1%]), RC (64 [20.7%]), and PC (84 [27.2%]). A PCF was noted in 36 of 161 patients in the FTT group (22.4%), 25 of 64 in the RC group (39.1%), and 29 of 84 in the PC group (34.5%). On multivariable analysis, patients undergoing PC or RC had a higher risk of PCF compared with those undergoing FTT (PC: RR, 2.2 [95% CI, 1.1-4.4]; RC: RR, 2.5 [95% CI, 1.3-4.8]). Undergoing FTT was associated with a clinically meaningful reduction in risk of PCF (RR, 0.6; 95% CI, 0.4-0.9; number needed to treat, 7). Subgroup analysis comparing inset techniques for the RC group showed a higher risk of PCF associated with PC (RR, 1.8; 95% CI, 1.1-3.0) and predominately pectoralis myofascial flap with onlay technique (RR, 1.9; 95% CI, 1.2-3.2), but there was no association of pectoralis myocutaneous flap with cutaneous paddle interposition with PCF (RR, 1.2; 95% CI, 0.5-2.8) compared with FTT with cutaneous inset. There were no clinically significant differences in functional outcomes between the groups. Conclusion and Relevance: In this study of patients with limited pharyngeal defects, interpositional fasciocutaneous closure technique was associated with reduced risk of PCF in the salvage setting, which is most commonly achieved by FTT in academic practices. Closure technique was not associated with functional outcomes at 1 and 2 years postoperatively.

Assessing social vulnerabilities of salivary gland cancer care, prognosis, and treatment in the United States.

BACKGROUND: Salivary gland cancers (SGC)-social determinants of health (SDoH) investigations are limited by narrow scopes of SGC-types and SDoH. This Social Vulnerability Index (SVI)-study hypothesized that socioeconomic status (SES) most contributed to SDoH-associated SGC-disparities. METHODS: Retrospective cohort of 24 775 SGCs assessed SES, minority-language status (ML), household composition (HH), housing-transportation (HT), and composite-SDoH measured by the SVI via regressions with surveillance and survival length, late-staging presentation, and treatment (surgery, radio-, chemotherapy) receipt. RESULTS: Increasing social vulnerability showed decreases in surveillance/survival; increased odds of advanced-presenting-stage (OR: 1.12, 95% CI: 1.07, 1.17), chemotherapy receipt (OR: 1.13, 95% CI: 1.03, 1.23); decreased odds of primary surgery (0.89, 0.84, 0.94), radiotherapy (0.91, 0.85, 0.97, p = 0.003) for SGCs. Trends were differentially correlated with SES, ML, HH, and HT-vulnerabilities. CONCLUSIONS: Through quantifying SDoH-derived SGC-disparities, the SVI can guide targeted initiatives against SDoH that elicit the most detrimental associations for specific sociodemographics.

Influence of Social Vulnerability in Treatment and Prognosis of Squamous Cell Carcinoma of the Tongue.

OBJECTIVE: To investigate the association of social determinants of health (SDoH) in squamous cell carcinoma of the tongue in the United States and to evaluate the real-world contribution of specific disparities. STUDY DESIGN: Retrospective cohort study. SETTING: United States. METHODS: The Centers for Disease Control and Prevention-Social Vulnerability Index (SVI) and National Cancer Institute-Surveillance, Epidemiology, and End Results Program database were used to study 62,103 adult tongue squamous cell carcinoma patients from 1975 to 2017. Regression analysis assessed trends in months of follow-up and survival across social vulnerability and 4 subcategories of social vulnerability. RESULTS: As overall SVI score increases (increased social vulnerability), there is a significant decrease in the average length of follow-up (22.95% decrease from 63.99 to 49.31 months; P < .001) across patients from the lowest and highest social vulnerability groups. As overall SVI score increases, there is a significant decrease in the average months of survival (28.00% decrease from 49.20 to 35.43 months; P < .001). There is also a significantly greater odds ratio (OR = 1.05; P < .001) of advanced cancer staging upon presentation at higher SVI scores. Patients with higher SVI scores have a lower OR (0.93; P < .001) of receiving surgery as their primary treatment when compared to patients with lower SVI scores. Patients with higher SVI scores also have a significantly greater OR (OR = 1.05; P < .001) of receiving chemotherapy as their primary treatment when compared to patients with lower SVI scores. CONCLUSION: Increased social vulnerability is shown to have a detrimental impact on the treatment and prognosis of patients with squamous cell carcinoma of the tongue.

Assessment of social vulnerability impact in care and prognosis of sinonasal cancers in the United States.

KEY POINTS: Social determinants of health interactively influence sinonasal cancer care and prognosis. Housing-transportation and socioeconomic status showed the largest associations with disparities. The social vulnerability index can reveal the social determinants of sinonasal cancers.

Social Vulnerability Association with Thyroid Cancer Disparities in the United States.

Background: As thyroid cancer incidence rises, it is increasingly valuable to recognize disparities in treatment and diagnosis. Prior investigations into social determinants of health (SDoH) are limited to pediatric populations or studies looking at single factors such as race or environmental influences. Utilizing the CDC-social vulnerability index and SEER-patient database to assess the amalgamated, real-world influence of varied SDoH and their quantifiable impact on thyroid cancer disparities across the United States. Methods: In a retrospective cohort study, 199,340 adult thyroid cancer patients from 1975 to 2017 were assessed for significant regression trends in months of follow-up/surveillance, survival, late staging, and treatment receipt across thyroid cancer-subtypes with increasing overall social vulnerability, as well as in 15 SDoH variables regarding socioeconomic status, minority-language status, household composition, and housing-transportation across all the U.S. counties while accounting for sociodemographic regional differences. Results: With increasing overall social vulnerability, decreases in months of follow-up were observed with patients with papillary, follicular, medullary, oncocytic, and anaplastic thyroid cancer (p = 0.001). Comparing lowest with highest vulnerability cohorts, relative decreases in months of surveillance ranged from 55.6% (14.5-6.5 months) with anaplastic to 17% (108.6-90.2) with oncocytic. Socioeconomic status vulnerabilities, followed by vulnerabilities in household composition and housing-transportation type, contributed to these overall trends. Similar survival decreases occurred across all thyroid cancer patients, ranging from 55.9% (9.6-4.2) with anaplastic to 28.3% (97-69.5) with oncocytic. Minority-language status vulnerabilities and housing-transportation types largely contributed to these trends. Increasing overall vulnerability was associated with increased odds of advanced staging for papillary (odds ratio [OR] = 1.07 [confidence interval, CI 1.03-1.12]) and decreased odds of indicated treatment via surgery (lowest, medullary: 0.91 [CI 0.84-0.99]), radiation therapy (lowest, anaplastic: 0.88 [CI 0.82-0.93]), and chemotherapy (lowest, oncocytic: 0.81 [CI 0.67-0.98]) were observed. Vulnerabilities in minority-language status and housing-transportation, followed by socioeconomic status vulnerabilities, were differential contributors to these overall vulnerability trends. Conclusions: Our results show significant detriments in thyroid cancer care and prognosis in the United States with increasing overall social vulnerability while identifying which SDoH quantifiably contribute more to disparities in inter-relational, real-world-like contexts.

Influence of Medicaid Expansion on Head and Neck Squamous Cell Carcinoma Presentation and Survival.

OBJECTIVE: To compare head and neck squamous cell carcinoma stage at presentation and survival in Medicaid-expanded states versus nonexpanded states. STUDY DESIGN: Retrospective cohort. SETTING: Northwestern University Feinberg School of Medicine. METHODS: The Head and Neck with human papillomavirus Status Database within the Surveillance, Epidemiology, and End Results (SEER) Program was queried for cases of head and neck squamous cell carcinoma (HNSCC) diagnosed in the years 2010 to 2016. Cases were grouped according to their respective state Medicaid expansion status. Multivariable logistic regressions and multivariable Cox proportional hazards models were used to evaluate associations with stage IV disease and survival. RESULTS: Compared to nonexpanded states, Medicaid-expanded states had a significantly larger proportion of Medicaid patients (20.3% vs 16.7%, P = .0009) and a significantly smaller proportion of uninsured patients (1.7% vs 10.1%, P < .0001). The case selection process resulted in 2215 patients meeting inclusion criteria. In multivariable analysis, cases under Medicaid expansion were 31% less likely to present with stage IV disease compared to cases in nonexpanded states (odds ratio: 0.69, 95% confidence interval [CI]: 0.51-0.93). In the multivariable Cox proportional hazards model, cases under Medicaid expansion had significantly better mortality outcomes and were 32% less likely to die compared to cases in nonexpanded states (hazard ratio: 0.68, 95% CI: 0.55-0.84). CONCLUSION: Medicaid expansion is associated with fewer stage IV cases and improved survival of HNSCC cases. These findings support continued efforts to expand Medicaid coverage.

Clinical outcomes following intraoperative pedicle disruption in fibula free flaps.

OBJECTIVES: Iatrogenic injury of the fibula free flap pedicle is rare. Postoperative flap survival and reconstructive outcomes following intraoperative pedicle severance are unknown. This study assesses free flap outcomes following accidental severance of the peroneal vessels. METHODS: Multi-institutional retrospective chart review from 2000 to 2020. RESULTS: Of 2975 harvested fibula free flaps, 26 had a history of pedicle severance during surgical reconstruction. Reasons for intraoperative pedicle severance included transection during muscular dissection 10/26 (39%), accidental severance with the bone saw 12/26 (46%), and other 4/26 (15.6%). The surgeon responsible for pedicle severance included residents 5/26 (19%), fellows 10/26 (39%), attendings 10/26 (39%), and unknown 1/26 (3.9%). The pedicle artery and vein were severed 10/26 (39%), artery 8/26 (31%), and vein 8/26 (31%). Truncated pedicle vessels were used 3/26 (11.7%), intraoperative anastomoses were performed 23/26 (89%). Postoperative revision in the OR within 7 days of surgery was required 6/26 (23%); 4 flaps were salvaged and 2 flaps failed, both arterial thrombosis. Flap failure was attributed to vascular thrombosis. Long-term flap survival and successful reconstructions were reported 24/26 (92%). CONCLUSION: Accidental severance of fibula free flap pedicle vessels can be corrected with intraoperative repair, without affecting long-term flap survival or reconstructive outcomes. Protecting the flap vessels while using the bone saw and during intramuscular dissection prevents accidental severance.

Assessment of Social Vulnerability in Pediatric Head and Neck Cancer Care and Prognosis in the United States.

Importance: Prior investigations in social determinants of health (SDoH) in pediatric head and neck cancer (HNC) have only considered a narrow scope of HNCs, SDoH, and geography while lacking inquiry into the interrelational association of SDoH with disparities in clinical pediatric HNC. Objectives: To evaluate the association of SDoH with disparities in HNC among children and adolescents and to assess which specific aspects of SDoH are most associated with disparities in dynamic and regional sociodemographic contexts. Design, Setting, and Participants: This retrospective cohort study included data about patients (aged ≤19 years) with pediatric HNC who were diagnosed from 1975 to 2017 from the Surveillance, Epidemiology, and End Results Program (SEER) database. Data were analyzed from October 2021 to October 2022. Exposures: Overall social vulnerability and its subcomponent contributions from 15 SDoH variables, grouped into socioeconomic status (SES; poverty, unemployment, income level, and high school diploma status), minority and language status (ML; minoritized racial and ethnic group and proficiency with English), household composition (HH; household members aged ≥65 and ≤17 years, disability status, single-parent status), and housing and transportation (HT; multiunit structure, mobile homes, crowding, no vehicle, group quarters). These were ranked and scored across all US counties. Main Outcomes and Measures: Regression trends were performed in continuous measures of surveillance and survival period and in discrete measures of advanced staging and surgery receipt. Results: A total of 37 043 patients (20 729 [55.9%] aged 10-19 years; 18 603 [50.2%] male patients; 22 430 [60.6%] White patients) with 30 different HNCs in SEER had significant relative decreases in the surveillance period, ranging from 23.9% for malignant melanomas (mean [SD] duration, lowest vs highest vulnerability: 170 [128] months to 129 [88] months) to 41.9% for non-Hodgkin lymphomas (mean [SD] duration, lowest vs highest vulnerability: 216 [142] months vs 127 [94] months). SES followed by ML and HT vulnerabilities were associated with these overall trends per relative-difference magnitudes (eg, SES for ependymomas and choroid plexus tumors: mean [SD] duration, lowest vs highest vulnerability: 114 [113] months vs 86 [84] months; P < .001). Differences in mean survival time were observed with increasing social vulnerability, ranging from 11.3% for ependymomas and choroid plexus tumors (mean [SD] survival, lowest vs highest vulnerability: 46 [46] months to 41 [48] months; P = .43) to 61.4% for gliomas not otherwise specified (NOS) (mean [SD] survival, lowest vs highest vulnerability: 44 [84] months to 17 [28] months; P < .001), with ML vulnerability followed by SES, HH, and HT being significantly associated with decreased survival (eg, ML for gliomas NOS: mean [SD] survival, lowest vs highest vulnerability: 42 [84] months vs 19 [35] months; P < .001). Increased odds of advanced staging with non-Hodgkin lymphoma (OR, 1.21; 95% CI, 1.02-1.45) and retinoblastomas (OR, 1.31; 95% CI, 1.14-1.50) and decreased odds of surgery receipt for melanomas (OR, 0.79; 95% CI, 0.69-0.91) and rhabdomyosarcomas (OR, 0.90; 95% CI, 0.83-0.98) were associated with increasing overall social vulnerability. Conclusions and Relevance: In this cohort study of patients with pediatric HNC, significant decreases in receipt of care and survival time were observed with increasing SDoH vulnerability.

Practice patterns in transoral robotic surgery: results of an American head and neck society survey.

To understand perioperative practices for transoral robotic surgery (TORS) among academic medical centers. An electronic cross-sectional survey was distributed to fellows and program directors participating in 49 American Head and Neck Society fellowships. Operative decisions, medical and swallowing management, and disposition planning were assessed. Thirty-eight responses were collected (77.6%). Twenty-three centers (60.5%) performed > 25 cases annually with the remainder performing fewer. The da Vinci Si was the most commonly used platform (n = 28, 73.7%). A majority of institutions advocated tailored resection to adequate margins (n = 27, 71.1%) over fixed subunit-based resection (n = 11, 28.9%). Most surgeons (n = 29, 76.3%) performed neck dissection concurrent with TORS, and 89.5% (n = 34) routinely ligated external carotid artery branches. A minority of institutions (n = 17, 45.9%) endorsed a standardized TORS care pathway. Antibiotic choices and duration varied, the most common choice being ampicillin/sulbactam (n = 21, 55.3%), and the most common duration being 24 h or less (n = 22, 57.9%). Multimodal analgesia was used at 36 centers (94.7%), steroids at 31 centers (81.6%), and pharmacologic venous thromboembolic prophylaxis at 29 centers (76.3%). Nasogastric feeding tubes were placed during surgery at 20 institutions (54.1%). Speech-language pathologists routinely performed postoperative swallow evaluations at 29 (78.4%) sites. Practice patterns are variable among institutions performing TORS. While certain surgical and postoperative practices were quite common, many institutions reported no standard TORS care pathway. Further understanding of the impact of individual practices on outcomes is necessary to develop evidence-based perioperative protocols for TORS.

Practice patterns of virtual surgical planning: Survey of the reconstructive section of the American Head and Neck Society.

PURPOSE: Virtual surgical planning (VSP), with custom made implants and guides represents a recent major advance. Nonetheless, knowledge related to practice patterns is limited. The purpose of this study was to provide data from the AHNS Reconstruction Section related to practice patterns, perceived value of VSP, as well as elucidate specific situations which represent high value for the application of VSP. MATERIALS AND METHODS: A multi-center web-based survey consisting of 30 questions regarding practice patterns related to VSP practices delivered via email to 203 members of the AHNS Reconstructive Surgery Section at institutions across North America. RESULTS: There was a 34% response rate (70/203). A majority of the respondents (96%) used VSP in approximately 50% of their mandibular reconstruction cases, and in 42% of maxillary cases. 46% reported using patient specific implants >75% of cases. Respondents estimated that ~17% of patients received dental implant reconstruction. The majority of respondents (71.0%) did not know the cost of VSP at their institution. The remaining respondents indicated the average cost was $6680 per case. VSP was felt to be necessary as a teaching tool by 55.9%. CONCLUSIONS: Our results demonstrate that a majority of respondents frequently utilize VSP in their practice for head and neck reconstruction. Complex, multi-unit reconstructions were felt to offer the greatest value when utilizing VSP. Future work should focus on increasing the rates of dental implant reconstruction in this population, optimizing value of VSP with careful case selection, and understanding the educational value and costs of these platforms.

Evaluating dysphagia and xerostomia outcomes following transoral robotic surgery for patients with oropharyngeal cancer.

BACKGROUND: We assessed long-term patient-reported dysphagia and xerostomia outcomes following definitive surgical management with transoral robotic surgery (TORS) in patients with oropharyngeal cancer (OPC) via a cross-sectional survey study. METHODS: Patients with OPC managed with primary oropharyngeal surgery as definitive treatment at least 1 year ago between 2015 and 2019 were identified. The M. D. Anderson Dysphagia Inventory (MDADI) and Xerostomia Inventory (XI) scores were compared across treatment types (i.e., no adjuvant therapy [TORS-A] vs. adjuvant radiotherapy [TORS+RT] vs. adjuvant chemoradiotherapy [TORS+CT/RT]). RESULTS: The sample had 62 patients (10 TORS-A, 30 TORS+RT, 22 TORS+CT/RT). TORS-A had clinically and statistically significantly better MDADI scores than TORS+RT (p = 0.03) and TORS+CT/RT (p = 0.02), but TORS+RT and TORS+CT/RT were not significantly different. TORS-A had clinically and statistically significantly less XI than TORS+RT (p < 0.01) and TORS+CT/RT (p < 0.01). CONCLUSIONS: Patients with OPC who have undergone TORS+RT or TORS+CT/RT following surgery face clinically worse dysphagia and xerostomia outcomes relative to patients who undergo TORS-A.

Consensus of free flap complications: Using a nomenclature paradigm in microvascular head and neck reconstruction.

BACKGROUND: We aim to define a set of terms for common free flap complications with evidence-based descriptions. METHODS: Clinical consensus surveys were conducted among a panel of head and neck/reconstructive surgeons (N = 11). A content validity index for relevancy and clarity for each item was computed and adjusted for chance agreement (modified kappa, K). Items with K < 0.74 for relevancy (i.e., ratings of "good" or "fair") were eliminated. RESULTS: Five out of nineteen terms scored K < 0.74. Eliminated terms included "vascular compromise"; "cellulitis"; "surgical site abscess"; "malocclusion"; and "non- or mal-union." Terms that achieved consensus were "total/partial free flap failure"; "free flap takeback"; "arterial thrombosis"; "venous thrombosis"; "revision of microvascular anastomosis"; "fistula"; "wound dehiscence"; "hematoma"; "seroma"; "partial skin graft failure"; "total skin graft failure"; "exposed hardware or bone"; and "hardware failure." CONCLUSION: Standardized reporting would encourage multi-institutional research collaboration, larger scale quality improvement initiatives, the ability to set risk-adjusted benchmarks, and enhance education and communication.

Survival of Patients With Non-Rhabdomyosarcoma Soft Tissue Sarcomas of the Head and Neck.

OBJECTIVE: To evaluate factors associated with overall survival (OS) of patients with non-rhabdomyosarcoma soft tissue sarcomas of the head and neck. STUDY DESIGN: Retrospective cohort study. METHODS: The National Cancer Database was queried for cases of non-rhabdomyosarcoma soft tissue sarcomas of the head and neck between 2004 and 2014. Cases were categorized according to the World Health Organization classification of soft tissue tumors. A multivariable Cox proportional hazards model was used to evaluate associations with OS. RESULTS: A total of 4,555 patients (63.6% male, 36.4% female, mean age 59.6 years) met inclusion criteria. The majority of tumors were classified as miscellaneous (35.9%), followed by vascular (20.1%), smooth muscle (13.5%), fibroblastic/myofibroblastic (12.1%), peripheral nerve (8.5%), adipocytic (7.4%), and undifferentiated (2.5%) sarcomas. The mean follow-up was 37.9 months, and overall mortality (MR) was 45.3%. The best prognosis was seen with fibroblastic/myofibroblastic sarcomas (MR = 20.6%, P < .001), whereas vascular sarcomas had the worst prognosis (MR = 67.6%, P < .001). Resection with clear margins had better OS than microscopically positive margins (hazard ratio [HR] = 1.43, P < .001) or grossly positive margins (HR = 2.97, P < .001). Radiation therapy was associated with better OS than no radiation (HR = 0.86, P = .001). CONCLUSION: Non-rhabdomyosarcoma soft tissue sarcomas of the head and neck are associated with significant mortality. OS differs based on histologic subcategorization. Resection of the primary tumor with clear margins demonstrates improved OS for all histologies, suggesting this modality remains the preferred primary treatment when feasible.

Contemporary management of carotid body tumors in a Midwestern academic center.

BACKGROUND: Carotid body tumors are rare, neurogenic tumors arising from the periadventitial chemoreceptive tissue of the carotid body. The purpose of this study is to ascertain the presentation and preoperative risk factors associated with surgical resection. METHODS: A single-center retrospective review of 25 carotid body tumor resections from 2002 to 2019. Demographics, periprocedural details, and postoperative outcomes were analyzed using Stata (Stata Corporation, College Station, TX). RESULTS: Among 25 patients, 64% were women, 84% were asymptomatic, and the mean age was 49 years (range 21-79). Forty-four percent of tumors were Shamblin III. Nine patients underwent preoperative embolization but did not correlate with decreased blood loss (299 cm3 vs 205 cm3, P = .35). The 30-day death, stroke, and cranial nerve injury rates were 0%, 8%, and 32%, respectively. Cranial nerve injuries included 20% vagus, 4% hypoglossal, 4% facial, and 4% glossopharyngeal, with permanent deficits in 4% (n = 1). Mean length of stay was 3.0 days (range 1-9 days). At a mean follow-up of 12 months (range 1-63 months), there has been no recurrence. CONCLUSION: Although carotid body tumors are uncommon in the Midwest, complete surgical resection is curative of these typically hormonally inactive tumors. Preoperative embolization did not affect blood loss, and the incidence of death, stroke, and permanent cranial nerve injury rates remained very low.

AHNS endocrine surgery section consensus statement on nasopharyngolaryngoscopy and clinic reopening during COVID-19: How to get back to optimal safe care.

This article provides best practice guidelines regarding nasopharyngolaryngoscopy and OHNS clinic reopening during the COVID-19 pandemic. The aim is to provide evidence-based recommendations defining the risks of COVID-19 in clinic, the importance of pre-visit screening in addition to testing, along with ways to adhere to CDC guidelines for environmental, source, and engineering controls.

Revaluation of Otolaryngologic Procedures With 10- and 90-Day Global Periods in the Medicare Physician Fee Schedule.

A recent investigation by the Centers for Medicare and Medicaid Services (CMS) suggests that physicians provide fewer postoperative visits (POVs) than expected for procedures with 10- and 90-day global periods. CMS is now contemplating revaluation of these procedures, which could result in lower Medicare payments to otolaryngologists. To estimate the impact of such reform on otolaryngologic procedures, we conducted a secondary subgroup analysis of CMS-contracted research, which used claims-based estimates of POVs to revalue procedures with 10- and 90-day global periods. Among the top 10 highest volume procedures performed in 2018, the proportion of median physician-reported to CMS-expected POVs ranged between 0.0% (myringotomy ± ventilation tube insertion, mouth biopsy, and complex wound repair) and 40.0% (total thyroidectomy). The top 5 procedures accounted for nearly three-quarters ($6.2 million and $8.6 million; 72.6%) of the estimated Medicare payment reduction. Further study is necessary to guide the development of equitable and effective payment reform.

Changes in head and neck oncologic practice during the COVID-19 pandemic.

INTRODUCTION: The COVID-19 pandemic has raised controversies regarding safe and effective care of patients with head and neck cancer. It is unknown how much the pandemic has changed surgeon practice. METHODS: A questionnaire was distributed to head and neck surgeons assessing opinions related to treatment and concerns for the safety of patients, self, family, and staff. RESULTS: A total of 88 head and neck surgeons responded during the study period. Surgeons continued to recommend primary surgical treatment for oral cavity cancers. Respondents were more likely to consider nonsurgical therapy for patients with early glottic cancers and HPV-mediated oropharynx cancer. Surgeons were least likely to be concerned for their own health and safety and had the greatest concern for their resident trainees. CONCLUSIONS: This study highlights differences in the willingness of head and neck surgeons to delay surgery or alter plans during times when hospital resources are scarce and risk is high.

OX40+ plasmacytoid dendritic cells in the tumor microenvironment promote antitumor immunity.

Plasmacytoid DCs (pDCs), the major producers of type I interferon, are principally recognized as key mediators of antiviral immunity. However, their role in tumor immunity is less clear. Depending on the context, pDCs can promote or suppress antitumor immune responses. In this study, we identified a naturally occurring pDC subset expressing high levels of OX40 (OX40+ pDC) enriched in the tumor microenvironment (TME) of head and neck squamous cell carcinoma. OX40+ pDCs were distinguished by a distinct immunostimulatory phenotype, cytolytic function, and ability to synergize with conventional DCs (cDCs) in generating potent tumor antigen-specific CD8+ T cell responses. Transcriptomically, we found that they selectively utilized EIF2 signaling and oxidative phosphorylation pathways. Moreover, depletion of pDCs in the murine OX40+ pDC-rich tumor model accelerated tumor growth. Collectively, we present evidence of a pDC subset in the TME that favors antitumor immunity.

The submental flap for head and neck reconstruction: Comparison of outcomes to the radial forearm free flap.

OBJECTIVES: To compare intraoperative, postoperative, functional, and oncologic outcomes of the submental island pedicled flap (SIPF) to the radial forearm free flap (RFFF). STUDY DESIGN: Retrospective review; comparison with statistical analysis. METHODS: A retrospective review was performed on patients at two tertiary care academic hospitals by a single surgeon. Consecutive patients who underwent cancer resection and reconstruction with SIPF or RFFF between 2004 and 2016 were included. Cancer staging, surgical procedure, hospital stay, complications, and functional and oncologic results were extracted. RESULTS: The study included 146 patients (57 SIPF; 89 RFFF). The most prevalent primary site was oral cavity, with a minority in the oropharynx, paranasal sinuses, or external face. Mean area of the SIPF was smaller at 28 cm2 compared to 48 cm2 for the RFFF. Operative time for SIPF was shorter at 6.5 hours compared to 9 hours for RFFF. Hospital stay was 8.0 days for SIPF patients and 10.0 days for RFFF patients. Multivariate analysis confirmed these differences were significant. Functional outcomes of speech quality and gastrostomy feeding tube dependence were similar between the SIPF and RFFF groups. There was no difference in local recurrence rate for SIPF (16%) and RFFF (19%), and there was no difference in overall recurrence. Kaplan-Meier curves showed no difference in recurrence between both groups, and multivariate logistic regression demonstrated no association between SIPF and local recurrence. CONCLUSION: Operative time and hospital stay are both significantly reduced with the SIPF. Functional and oncologic results are similar with no contraindication to the SIPF. The SIPF is a good first-line choice for head and neck reconstruction. LEVEL OF EVIDENCE: 3 Laryngoscope, 130:S1-S10, 2020.
