Metastatic Meningioma of the Neck: A Case Report and Systematic Review.

BACKGROUND: Although meningiomas are the most common central nervous system neoplasms, extracranial metastases are exceedingly rare. There are even fewer reports of metastatic meningiomas to the neck. METHODS: We described a patient with multiply recurrent orbital meningioma with metastasis to the neck found incidentally during neck exploration for composite resection and free tissue reconstruction. We performed a systematic review for all records pertaining to metastatic meningiomas to the cervical regions. RESULTS: We found 9 previous reports of cervical metastatic meningiomas. Almost all cases underwent extensive local resection. There was no evidence of an association between the histological grade of the tumor and risk of metastasis to the neck. Cervical lymph node dissemination is more common in patients presenting after previous primary tumor resection. CONCLUSIONS: In the context of a neck mass, our findings suggest that metastatic meningioma should be included in the differential diagnosis, especially in patients with previous resections.

Outcomes After Tracheostomy in COVID-19 Patients.

OBJECTIVE: To determine the outcomes of patients undergoing tracheostomy for COVID-19 and of healthcare workers performing these procedures. BACKGROUND: Tracheostomy is often performed for prolonged endotracheal intubation in critically ill patients. However, in the context of COVID-19, tracheostomy placement pathways have been altered due to the poor prognosis of intubated patients and the risk of transmission to providers through this highly aerosolizing procedure. METHODS: A prospective single-system multi-center observational cohort study was performed on patients who underwent tracheostomy after acute respiratory failure secondary to COVID-19. RESULTS: Of the 53 patients who underwent tracheostomy, the average time from endotracheal intubation to tracheostomy was 19.7 days ±â€Š6.9 days. The most common indication for tracheostomy was acute respiratory distress syndrome, followed by failure to wean ventilation and post-extracorporeal membrane oxygenation decannulation. Thirty patients (56.6%) were liberated from the ventilator, 16 (30.2%) have been discharged alive, 7 (13.2%) have been decannulated, and 6 (11.3%) died. The average time from tracheostomy to ventilator liberation was 11.8 days ±â€Š6.9 days (range 2-32 days). Both open surgical and percutaneous dilational tracheostomy techniques were performed utilizing methods to mitigate aerosols. No healthcare worker transmissions resulted from performing the procedure. CONCLUSIONS: Alterations to tracheostomy practices and processes were successfully instituted. Following these steps, tracheostomy in COVID-19 intubated patients seems safe for both patients and healthcare workers performing the procedure.

Pectoralis major muscle flap use in a modern head and neck free flap practice.

PURPOSE: Pectoralis major muscle flaps (PMMF) are a commonly used reconstructive modality to repair head and neck defects. As the use of free flap reconstruction is increasingly practiced in the head and neck, the role of the PMMF may be changing as well. This study sought to analyze indications and outcomes for PMMF following head and neck resections from one surgeon's experience. MATERIALS AND METHODS: Retrospective review from December 1, 2013 through September 30, 2017 at a tertiary care academic medical center. Indications for the PMMF were examined as well as surgical outcomes. Basic demographic data, patient head and neck cancer history, history of radiation and/or chemotherapy, and history of previous reconstructive procedures were obtained and compared across all subjects. RESULTS: Forty patients underwent a PMMF within the designated time frame. The majority of patients were male (83%) and the average age was 65 years (range 55.4-74.6 years). Of the 40 cases, 9 of the PMMFs were performed as primary reconstruction of the defect. In the remaining 31 cases, these flaps were utilized as a secondary reconstructive option following fistula formation (13), dehiscence (6), need for an additional flap for recurrent disease (6) infection (4), or major bleeding (2). In every case that it was utilized, the PMMF was the definitive reconstruction. Within the same time frame, 429 free flaps were performed by the same surgeon, with an average of 125 free flaps performed yearly. The rate of total flap failure overall was 3.9%. The other failed free flap reconstructive options used besides a PMMF were secondary free flaps (11), local wound care (4), or obturator placement (2). The secondary pectoralis flaps occurred following 7.2% of free flaps with total or partial failure that were performed within the same time range. The indications for the PMMF did not change or evolve during the time frame of the study. CONCLUSIONS: Although free flaps were performed with far greater frequency than PMMFs at our institution, the PMMF demonstrated continued utility as a secondary reconstructive option. For a surgeon who performs a high volume of free flaps, preservation of the pectoralis muscle and associated vasculature for possible later secondary reconstruction should be considered due to its strong efficacy.

Predictors of Nodal Metastasis in Mucoepidermoid Carcinoma of the Oral Cavity and Oropharynx.

INTRODUCTION: Mucoepidermoid carcinoma (MEC) of the upper aerodigestive tract (UADT) is an uncommon malignancy, with limited literature available on its clinical and pathologic characteristics. Here, we describe the behavior of MEC of the UADT including pathologic characteristics and predictors of nodal metastasis. METHODS: Retrospective cohort study of patients with MEC of the UADT treated at an academic medical center from January 2008 to May 2018. Data was collected about demographics and tumor characteristics including clinical and histological data. The two-tailed Student t test and χ2 analysis were performed to assess for predictors of nodal metastasis. RESULTS: We identified 44 patients with minor salivary gland MEC of the oral cavity (OC) and oropharynx (OP). All patients were treated with primary site surgery. The primary site was the OC in 25 patients (57%) and OP in 19 (43%). Low-grade histology was seen in 27 specimens (61.4%), intermediate histology in 9 specimens (20.5%), and high-grade histology in 8 specimens (18.2%). Perineural invasion was noted in 10 specimens (22.7%). Neck dissection was performed in 17 patients (39%), with pathologically positive nodes found in 9 (20.5%). Notably, 5 of the 9 positive nodal specimens were found in clinically node-negative necks. Pathologically positive cervical lymph nodes were significantly associated with the OP as the primary site (p = 0.0005), perineural invasion (p = 0.012), lymphovascular invasion (p < 0.001), and high-grade histology (p = 0.004) in the primary specimen. DISCUSSION: MEC of the UADT is an uncommon malignancy. Our findings suggest elective neck dissection should be considered with perineural and lymphovascular invasion, high-grade tumor, and the OP as the primary site.

Anatomical Variations of the Superficial Radial Nerve Encountered during Radial Forearm Free Flap Elevation.

A frequently encountered anatomical structure in the elevation of a radial forearm free flap is the superficial branch of the radial nerve. This structure has a relatively consistent anatomic location, but variations do occur. We present a case where the superficial branch of the radial nerve was in an usual position but remained superficial to the brachioradialis throughout its course. Two previous reports also describe the superficial branch of the radial nerve remaining superficial to the brachioradialis, although, in these reports, the nerve was more medial than is typical. We postulate that one of the most common anatomic variations of the superficial branch of the radial nerve is for it to remain superficial to the brachioradialis. As this variation could potentially be confused with the medial or lateral antebrachial cutaneous nerves, it is important for the reconstructive surgeon to be aware of this to prevent inadvertent injury.

Defining the Role of Free Flaps for Transoral Robotic Surgery.

BACKGROUND: Transoral surgical techniques for oropharyngeal tumors have been widely accepted, yet often results in a significant functional deficit. Current reports on the safety, feasibility, and swallowing performance after microvascular reconstruction are limited to small volume case series. MATERIALS AND METHODS: Retrospective review of 42 consecutive patients, between December 2013 and May 2016, who underwent transoral robotic surgery oropharyngectomy followed by microvascular reconstruction. RESULTS: Swallowing outcomes postoperatively resulted in 39 (93%) of patients tolerating oral intake postoperatively, with 13 (87%) of 15 patients at 1-year follow-up consuming an entirely oral diet. Thirty-eight (95%) of 40 patients who underwent a tracheostomy at the time of surgery were ultimately decannulated. No patients experienced complete flap failure in the current study. CONCLUSIONS: Minimally invasive transoral surgical techniques have offered the opportunity to minimize surgical morbidity and potentially deintensify adjuvant therapies. Reconstructive options have evolved to match surgical advances seen with robotic surgeries of oropharyngeal cancers. Microvascular reconstruction has been indicated in select patients including those with extensive soft palate resection, primary tumor abutment of the medial pterygoid musculature, exposure of internal carotid artery vasculature, prior radiation therapy, or a significant defect of the oropharyngeal sphincter. Select patients, based on previously identified criteria, were preoperatively identified as suitable candidates for microvascular reconstruction of oropharyngeal defects. This study demonstrates that complex transoral robotic surgical defects are amenable to microvascular reconstructive in carefully selected patients.

An Airway Rapid Response System: Implementation and Utilization in a Large Academic Trauma Center.

BACKGROUND: Rapid response teams mobilize resources to patients experiencing acute deterioration. Failed airway management results in death or anoxic brain injury. A codified, systems-based approach to bring personnel and equipment to the bedside for multidisciplinary airway assessment and rescue was reflected in the initial implementation of an airway rapid response (ARR) team. METHODS: A retrospective review of records of 117 ARR events in a 40-month period (August 2011-November 2014) was undertaken at the Hospital of the University of Pennsylvania, a 789-bed, academic, urban, tertiary care, Level 1 trauma center. RESULTS: Of the 117 ARR events, 60 (51.3%) were called in the ICU, and 43 (36.8%) in the general ward. A definitive airway was secured in all patients for whom airway management was attempted. A new surgical airway was performed in five of the patients. Seven patients went to the operating room for airway management. Nine patients died or had care withdrawn shortly after the ARR. CONCLUSION: Difficult airway emergencies represent a small but critical element of airway rescue scenarios. Before the implementation of the ARR system, the process to bring the right team, equipment, expertise, and consensus on the right actions to critical airway emergencies was ad hoc. ARR activation, which brings multidisciplinary airway consultation, expert skills, and advanced airway equipment to the bedside, contributed to definitive airway management for surgical and nonsurgical airways. Performance of a bedside emergency surgical airway was uncommon. The ARR system represents a significant enhancement of the "anesthesia stat" system that typifies the airway emergency system at many institutions.

Risk Factors for Plate Infection, Exposure, and Removal in Mandibular Reconstruction.

OBJECTIVE: Mandibular plate reconstruction (MPR) is often indicated after tumor ablation, osteoradionecrosis excision, and traumatic bone loss to restore oral functionality and facial cosmetics. There are limited analyses identifying risk factors that lead to plate infection (PIn), exposure, and removal ("plate complications"). STUDY DESIGN: Retrospective cohort study. SETTING: Academic tertiary medical center. METHODS: Patients who underwent MPR from 2013 to 2022 were identified. Risk factors for plate complications were analyzed based on demographic, clinical, intraoperative, and postoperative factors. Multivariable analysis was conducted with logistic regression. Survival analysis was conducted with a Cox model. RESULTS: Of the 188 patients analyzed, 48 (25.5%) had a plate complication [infection: 22 (11.7%); exposure: 23 (12.2%); removal: 35 (18.6%)]. Multivariate analysis revealed predictive associations between at least 1 plate complication and the following variables: smoking status, soft tissue defect size, number of plates, average screw length, and various postoperative complications. Other associations approached the threshold for significance. Prior and adjuvant radiation therapy, type of free flap, stock versus custom plates, and perioperative antibiotic prophylaxis regimens were not associated with plate complications. No plate complication was independently associated with lower overall survival. PIn (hazard ratio, HR: 7.99, confidence interval, CI [4.11, 15.54]) and exposure (HR: 3.56, CI [1.79, 7.08]) were independently associated with higher rates of plate removal. CONCLUSION: Plate complications are relatively common after MPR. Smoking history, specific disease characteristics, hardware used during surgery, and postoperative complications may help identify higher-risk patients, but additional larger-scale studies are needed to validate our findings and resolve discrepancies in the current literature.

Airway trauma in a high patient volume academic cardiac electrophysiology laboratory center.

BACKGROUND: Providing anesthesia and managing airways in the electrophysiology suite can be challenging because of its unique setting outside of the conventional operating room. We report our experience of several cases of reported airway trauma including tongue and pharyngeal hematoma and vocal cord paralysis in this setting. METHODS: We analyzed all of the reported airway trauma cases between December 2009 and January 2011 in our cardiac electrophysiology laboratories and compared these cases with those without airway trauma. Data from 87 cases, including 16 cases with reported airway trauma (trauma group) and 71 cases without reported airway trauma from the same patient population pool at the same period (control group), were collected via review of medical records. RESULTS: Airway trauma was reported for 16 patients (0.7%) in 14 months among 2434 anesthetic cases. None of these patients had life-threatening airway obstruction. The avoidance of muscle relaxants during induction in patients with a body mass index less than 30 was found to be a significant risk factor for airway trauma (P = 0.04; odds ratio, 10; 95% confidence interval, 1.1-482). Tongue or soft tissue bite occurred in 2 cases where soft bite block was not used during cardioversion. No statistically significant difference was found between the trauma and the control groups for preprocedure anticoagulation, anticoagulation during the procedure, or reversal of heparin at the end of the procedure. CONCLUSIONS: The overall incidence of reported airway trauma was 0.7% in our study population. Tongue injury was the most common airway trauma. The cause seems to have been multifactorial; however, airway management without muscle relaxant emerged as a potential risk factor. Intubation with muscle relaxant is recommended, as is placing a soft bite block and ensuring no soft tissue is between the teeth before cardioversion.

Post-operative Monitoring for Head and Neck Microvascular Reconstruction in the Era of Resident Duty Hour Restrictions: A Retrospective Cohort Study Comparing 2 Monitoring Protocols.

OBJECTIVES: To determine whether 2 different methods of post-operative head and neck free flap monitoring affect flap failure and complication rates. METHODS: A retrospective chart review of 803 free flaps performed for head and neck reconstruction by the same microvascular surgeon between July 2013 and July 2020 at 2 separate hospitals within the same healthcare system. Four-hundred ten free flaps (51%) were performed at Hospital A, a medical center where flap checks were performed at frequent, scheduled intervals by in-house resident physicians and nurses; 393 free flaps (49%) were performed at Hospital B, a medical center where flap checks were performed regularly by nursing staff with resident physician evaluation as needed. Total free flap failure, partial free flap failure, and complications (consisting of wound infection, fistula, and reoperation within 1 month) were assessed. RESULTS: There were no significant differences between Hospitals A and B when comparing rates of total free flap failure, partial free flap failure, complication, or re-operation (P = .27, P = .66, P = .65, P = .29, respectively). There were no significant differences in urgent re-operation rates for flap compromise secondary to thrombosis and hematoma (P = .54). CONCLUSIONS: In our series, free flap outcomes did not vary based on the degree of flap monitoring by resident physicians. This data supports the ability of a high-volume, well-trained, nursing-led flap monitoring program to detect flap compromise in an efficient fashion while limiting resident physician obligations in the age of resident duty hour restrictions.

Institutional analysis of intra- and post-operative tracheostomy management for risk reduction.

Objectives: Determine variability in intra- and post-operative management of tracheostomies (trachs) at our institution as existing literature suggests that trachs are a frequent trigger for airway-related emergencies. Catalyze the development of an institution-wide protocols for trach care. Methods: A 39-question online survey was sent to 55 providers who perform open and percutaneous trachs at three of the hospitals within our large, urban, academic medical center. These providers were identified by surveillance of the operating room schedules for 1 year. Results: The survey was completed by 40 of the 53 eligible providers (75.5%). Response rate by question varied. Respondents included members of all departments that perform trachs at our institution (Otorhinolaryngology, Trauma Surgery, Thoracic Surgery, General Surgery, Cardiovascular Surgery and Interventional Pulmonology).While most responses demonstrated uniformity in practice, notable variations included the following: 80% of percutaneous trach providers stated that morbid obesity was not a contraindication to performing a trach outside of the operating room (n = 20) while 58% of open trach providers stated that morbid obesity was a contraindication; only 35% of open trach providers perform a Bjork flap (n = 350). The survey also identified significant variability in practice with regards to timing of trach suture removal. Discussion: Lack of uniformity was identified in several practices related to intra- and post-operative tracheostomy care. Results did, however, trend toward consensus in many areas. The results are being used to establish a more consistent approach to tracheostomy management across our institution to ensure standardization of practice amidst the rapidly evolving practices of trach placement. Implications for practice: With ongoing evolution in the methods of trach placement and its management, the concepts put forth here will be a resource for health care providers at other institutions to consider intra-institutional analysis and establishment of practice standardization.

Financial impact of the COVID-19 pandemic on an academic otolaryngology department.

Objective: To quantify the financial impact of the coronavirus disease (COVID-19) pandemic on an academic otolaryngology department. Methods: A year-over-year comparison was used to compare department revenue from April 2020 and April 2021 as a percentage of baseline April 2019 activity. Results: At the onset of the COVID-19 pandemic in April 2020, total department charges decreased by 83.4%, of which outpatient clinic charges were affected to the greatest extent. One year into pandemic recovery, department charges remained down 6.7% from baseline, and outpatient clinic charges remained down 9.9%. The reduction in outpatient clinic charges was mostly driven by a decrease in in-office procedure charges. Conclusion: Given that precautions to mitigate the risk of viral transmission in the health care setting are likely to be long-lived, it is important to consider the vulnerabilities of our specialty to mitigate financial losses going forward.

A benchmark for oncologic outcomes and model for lethal recurrence risk after transoral robotic resection of HPV-related oropharyngeal cancers.

OBJECTIVES: Increasing use of transoral robotic surgery (TORS) is likely to impact outcomes for HPV+ oropharyngeal squamous cell carcinomas (OPSCCs). We aimed to describe oncologic outcomes for a large HPV+ OPSCC cohort after TORS and develop a risk prediction model for recurrence under this treatment paradigm. MATERIALS AND METHODS: 634 HPV+ OPSCC patients receiving TORS-based therapy at a single institution were reviewed retrospectively to describe survival across the entire cohort and for patients suffering recurrence. Risks for distant metastatic recurrence (DMR) and locoregional recurrence (LRR) were modeled using multivariate logistic regression analyses of case-control sub-cohorts. RESULTS: 5-year overall and recurrence-free survival were 91.2% and 86.1%, respectively. 5-year overall survival was 52.5% following DMR and 83.3% after isolated LRR (P = .01). In case-control analyses, positive surgical margins were associated with DMR (adjusted OR 5.8, CI 2.1-16.0, P = .001), but not isolated LRR, and increased DMR risk 4.2 fold in patients with early clinical stage disease. By contrast, LRR was associated with not receiving recommended adjuvant therapy (OR 13.4, CI 6.3-28.5, P < .001). CONCLUSIONS: This study sets a benchmark for oncologic outcomes from HPV+ OPSCC after TORS-based therapy. Under this treatment paradigm, margins are relevant for assessing lethal recurrence risk during clinical trial design and post-treatment surveillance.

Sialendoscopy for sialodocholithiasis following submandibular gland excision: six variations on a theme.

Sialendoscopy is a minimally invasive technique that facilitates the diagnosis and treatment of sialolithiasis. This case series presents the novel use of sialendoscopy to treat sialodocholithiasis in six patients with a non-functional or surgically absent submandibular gland by a single surgeon at the University of Pennsylvania Health System between March 2013 and December 2019. The four female and two male patients had a median age of 56 years and mean follow-up of 16.2 months (range 1-44.5). All stones were successfully removed using sialendoscopy, and in 5 patients a combined approach was utilized. All patients remain asymptomatic at last clinical follow-up. We conclude that sialendoscopy is a viable, minimally invasive method for managing sialodocholithiasis in patients with prior submandibular gland excision or atretic gland. It is also useful as an assistive tool when approaching complex transcervical or transoral procedures in previously instrumented patients.

Value of Intensive Care Unit-Based Postoperative Management for Microvascular Free Flap Reconstruction in Head and Neck Surgery.

Importance: Although routine postoperative care for microvascular free flap reconstruction typically involves admission to the intensive care unit (ICU), few studies have investigated the effect of postoperative care setting on clinical outcomes and institution cost. Objectives: To determine the value of non-ICU-based postoperative management for free tissue transfer for head and neck surgery, in terms of clinical outcomes and cost-effectiveness. Design, Setting, and Participants: This is a retrospective cohort study of two groups of adults who underwent vascularized free tissue transfer from October 2013 to October 2017 at an academic tertiary care center and community-based hospital, respectively. Postoperative management differed such that the first group recovered in a protocol-driven non-ICU setting and the second group was cared for in a planned admission to the ICU. A single surgeon performed all tissue harvest and reconstruction at both centers. Main Outcomes and Measures: Descriptive statistics and cost analyses were performed to compare clinical outcomes and total surgical and downstream direct cost to the institution between the two patient groups. Categorical variables were compared using χ2 test where appropriate. Results: Among a total of 338 patients who underwent microvascular free flap reconstruction for head and neck surgical defects, there was no significant difference in patient characteristics such as demographics, comorbidities, history of surgical resection, prior free flap, and locoradiation between the postoperative ICU cohort (n = 146) and protocol-driven non-ICU cohort (n = 192). There were 16 patients in the non-ICU group who spent >3 days in the ICU postoperatively secondary to patient comorbidities and patient care priorities. Still, the average ICU length of stay was 7 days (interquartile range [IQR] 6-9 days) for the planned ICU cohort versus 1 day (IQR 0-1) for the non-ICU group (p < 0.00001). There was no difference in operative variables such as donor site, case length, or total length of stay, and postoperative management in the ICU versus non-ICU setting resulted in no significant difference in terms of flap survival, reoperation, readmission, and postoperative complications. However, average cost of care was significantly higher for patients who received ICU-based care versus non-ICU postoperative care. Specifically, room and board were 239% more costly for the planned ICU care group than the non-ICU setting (p < 0.00001). Conclusions and Relevance: This study demonstrates that postoperative management after vascularized free tissue transfer in a non-ICU setting is equivalent to standard ICU-based management, in terms of clinical outcomes, while being less costly.

Revisiting the Recommendation for Contralateral Tonsillectomy in HPV-Associated Tonsillar Carcinoma.

OBJECTIVE: Despite epidemiologic evidence that second primaries occur infrequently in HPV (human papillomavirus)-associated oropharyngeal squamous cell carcinoma, recent recommendations advocate for elective contralateral palatine tonsillectomy. We aimed to study this discordance and define the necessary extent of up-front surgery in a large contemporary cohort with long-term follow-up treated with unilateral transoral robotic surgery. We hypothesized that second primaries are discovered exceedingly rarely during follow-up and that survival outcomes are not compromised with a unilateral surgical approach. STUDY DESIGN: Retrospective cohort analysis. SETTING: Tertiary care academic center between 2007 and 2017. METHODS: Records for patients with p16-positive oropharyngeal squamous cell carcinoma of the tonsil and workup suggestive of unilateral disease who underwent ipsilateral transoral robotic surgery were analyzed for timing and distribution of locoregional recurrence, distant metastases, and second primary occurrence as well as survival characteristics. RESULTS: Among 295 included patients, 21 (7.1%) had a locoregional recurrence; 17 (5.8%) had a distant recurrence; and 3 (1.0%) had a second primary during a median follow-up of 48.0 months (interquartile range, 29.5-62.0). Only 1 (0.3%) had a second primary found in the contralateral tonsil. The 2- and 5-year estimates of overall survival were 95.5% (SE, 1.2%) and 90.1% (SE, 2.2%), respectively, while the 2- and 5-year estimates of disease-free survival were 90.0% (SE, 1.8%) and 84.7% (SE, 2.3%). CONCLUSION: Second primary occurrence in the contralateral tonsil was infrequent, and survival outcomes were encouraging with unilateral surgery. This provides a rationale for not routinely performing elective contralateral tonsillectomy in patients whose workup suggests unilateral disease.

Retropharyngeal Internal Carotid Artery Management in TORS Using Microvascular Reconstruction.

OBJECTIVES: Guidelines for transoral robotic surgery (TORS) have generally regarded patients with retropharyngeal carotid arteries as contraindicated for surgery due to a theoretical risk of intraoperative vascular injury and/or perioperative cerebrovascular accident. We aimed to demonstrate that careful TORS-assisted resection and free flap coverage could not only avoid intraoperative injury and provide a physical barrier for vessel coverage but also achieve adequate margin control. STUDY DESIGN: Retrospective cohort analysis. METHODS: Retrospective review of patients with oropharyngeal malignancies and radiologically confirmed retropharyngeal carotid arteries who underwent TORS, concurrent neck dissection, and free flap reconstruction between 2015 and 2019. RESULTS: Twenty patients were included, 19 (95.0%) with tonsillar tumors and one (5.0%) with a tongue base tumor with significant tonsillar extension. Eighteen patients (90.0%) received a radial artery forearm flap, one (5.0%) an ulnar artery forearm flap, and one (5.0%) an anteromedial thigh flap. All 20 (100%) flaps were inset through combined transcervical and transoral approaches without mandibulotomy. There were no perioperative mortalities, carotid injuries, oropharyngeal bleeds, cervical hematomas, or cerebrovascular accidents. One patient (5.0%) had a free flap failure requiring explant. All patients underwent decannulation and resumed a full oral diet. The mean length of hospitalization was 6.8 (standard deviation 1.2) days. One (5.0%) patient had a positive margin. CONCLUSION: In this analysis, 20 patients with oropharyngeal malignancy and retropharyngeal carotid arteries underwent TORS, neck dissection, and microvascular reconstruction without serious complication (perioperative mortality, vascular injury, or neurologic sequalae) with an acceptable negative margin rate. These results may lead to a reconsideration of a commonly held contraindication to TORS. LEVEL OF EVIDENCE: 3 Laryngoscope, 131:E821-E827, 2021.

Oncologic outcomes of transoral robotic surgery for HPV-negative oropharyngeal carcinomas.

BACKGROUND: Patients with human papillomavirus (HPV)-negative oropharyngeal squamous cell carcinoma (OPSCC) continue to experience disappointing outcomes following chemoradiotherapy (CRT) and appreciable morbidity following historical surgical approaches. We aimed to investigate the oncologic outcomes and perioperative morbidity of a transoral robotic surgery (TORS) approach to surgically resectable HPV-negative OPSCC. METHODS: Retrospective analysis HPV-negative OPSCC patients who underwent TORS, neck dissection and pathology-guided adjuvant therapy (2005-2017). RESULTS: Fifty-six patients (91.1% stage III/IV) were included. Three-year overall survival, locoregional control, and disease-free survival were 85.5%, 84.4%, and 73.6%, respectively (median follow-up 30.6 months, interquartile range 18.4-66.6). Eighteen (32.1%) patients underwent adjuvant radiotherapy and 20 (39.3%) underwent adjuvant CRT. Perioperative mortality occurred in one (1.8%) patient and hemorrhage occurred in two (3.6%) patients. Long-term gastrostomy and tracheostomy rates were 5.4% and 0.0%, respectively. CONCLUSION: The TORS approach for resectable HPV-negative OPSCC can achieve encouraging oncologic outcomes with infrequent morbidity.
