AbstractBackgroundBuccal squamous cell carcinoma (SCC) is a locoregionally aggressive malignancy, representing a small subset of oral cancers in North America. We investigated the prognostic value of several clinicopathologic factors in a cohort of patients diagnosed with buccal SCC.MethodsBetween years 1992 and 2017, 52 patients were diagnosed with conventional buccal SCC. Archival surgical pathology material was retrospectively reviewed for reportable findings according to the latest reporting guidelines published by the College of American Pathologists. Clinical data were obtained through chart review.ResultsThe majority of patients were of older age, current or past smokers, and without specific gender predilection. Most presented at a clinically advanced stage and were treated with surgery alone, or surgery followed by adjuvant radiotherapy. The tumor recurred in about 40% of patients, and almost half of the patients died from the disease by the end of the follow‐up period. The worst pattern of invasion (WPOI) was associated with greater depth of invasion (DOI) (P = .031) and perineural invasion (P < .001). In univariate analyses, older age (P = .004), positive nodal status (P = .047), lymphovascular invasion (P = .012), perineural invasion (P = .05), and WPOI‐5 (P = .015) were adverse predictors of 5‐year overall survival (OS). In multivariate analysis, older age (P = .011), WPOI‐5 (P < .001), and perineural invasion (P = .001) remained statistically significant independent prognosticators of worse 5‐year OS.ConclusionsOlder age, WPOI‐5, and perineural invasion are significant prognosticators of worse OS. WPOI is associated with DOI, a finding which may have important implications for the pathogenesis and biologic behavior of the disease.

ObjectivesTo describe pain experience and opioid use after major head and neck reconstructive surgery.Study DesignRetrospective cohort study.MethodsPatients undergoing major head and neck surgery with microvascular free tissue transfer (free flaps) at a tertiary academic center were included. Pain scores (0–10) and demographic and clinical data were ascertained from medical records. Discharge opioid prescriptions and refills obtained within 30 days were recorded. Patient characteristics were compared with pain scores using nonparametric rank‐sum tests and with likelihood of refill using logistic regression models to calculate adjusted odds ratios (aORs) with 95% confidence intervals (CIs).ResultsThe study population comprised 445 patients. Median age was 60 years (interquartile range 50–68). Most patients had cancer (N = 350, 78%). The majority of free flaps were fibula (N = 153, 34%) or radial forearm (N = 159, 36%). Older patients reported significantly lower pain scores, whereas patients with opioid tolerance, anxiety, current smokers, and those undergoing larger volume resections or boney free flaps reported significantly higher pain scores. One‐quarter (N = 115, 26%) of patients obtained opioid refills. Patients aged ≥ 60 years had one‐half the odds of obtaining a refill compared with patients aged < 60 years (adjusted odds ratio [aOR] = 0.52, 95% confidence interval [CI] = 0.33–0.84), whereas surgical defect volume ≥ 100 cm3 (aOR = 1.92, 95% CI = 1.21–3.07) and higher pain score (aOR = 1.19, 95% CI = 1.07–1.32 per 1 point increase) increased the odds of refill.ConclusionContinued opioid use after discharge is common among patients undergoing major head and neck reconstruction, particularly for younger patients and after more extensive surgery. Older patients reported lower pain intensity and were less likely to obtain opioid refills, highlighting the wisdom of judicious opioid use for this vulnerable population.Level of EvidenceIV Laryngoscope, 130: E469–E478, 2020

ObjectivesClinical variables affecting anesthetic recovery following transoral robotic surgery (TORS) to resect oropharyngeal squamous cell carcinoma have not been described. We aimed to explore risk factors associated with prolonged postanesthesia recovery following TORS.Study DesignRetrospective case‐control study.SettingTertiary referral center, January 2010 to November 2016.Subjects and MethodsPatients included adults undergoing primary TORS ± neck dissection for oropharyngeal squamous cell carcinoma. Patients were categorized by phase I recovery time into the “goal” recovery group (75th percentile [lower 3 quartiles], n = 272) and the “prolonged” recovery group (n = 91). Univariate and multivariate logistic regression analyses were performed to assess the associations between clinical characteristics and prolonged phase I recovery.ResultsA total of 363 patients were included. Median (interquartile range) duration of postanesthesia recovery was 1.5 hours (1.0‐2.0). Prolonged recovery was associated with isoflurane (odds ratio, 2.83 [95% CI, 1.56‐5.14], P <. 001), midazolam (2.77 [1.50‐5.12], P =. 001), and larger opioid doses (1.26 [1.01‐1.58] per 10‐mg intravenous morphine equivalents, P =. 040) and inversely associated with multimodal antiemetic therapy (0.34 [0.15‐0.78], P =. 011). Prolonged cases had higher rates of postoperative nausea and vomiting (n = 43 [47.2%] vs 86 [31.6%], P =. 008), respiratory depression (28 [30.8%] vs 12 [4.4%], P <. 001), sedation (Richmond Agitation‐Sedation Scale < –2; 26 [28.6%] vs 35 [12.9%], P =. 001), severe pain (numeric rating score ≥7; 31 [34.4%] vs 45 [17.2%], P =. 001), and longer hospital stays (4 vs 3 days, P <. 001).ConclusionsSeveral anesthetic factors are associated with anesthesia recovery duration, which may be shortened by efforts to reduce postoperative sedation, severe pain, and nausea/vomiting. Shortened anesthesia recovery time may reduce hospital stay.

The radial forearm free flap (RFFF) has become a workhorse for soft tissue reconstruction following surgical ablation of head and neck cancer. Given the popularity of the RFFF, it is important to understand potential variants of upper extremity vascular anatomy and the effects of these findings on pre- and intraoperative planning. The purpose of this series is to synthesize the existing literature to raise awareness for potential radial artery aberrations during planned reconstruction.

Abstract Background The da Vinci single‐port (SP) robot is a new instrument for transoral robotic surgery (TORS) in oropharyngeal cancers (OPSCCs). We describe one‐year SP surgical outcomes and compare them to da Vinci Si outcomes. Methods Retrospective cohort study at a high‐volume TORS center. Consecutive patients undergoing TORS SP procedures from 10/2018 to 09/2019 were included. SP OPSCC outcomes were compared to a historical cohort of Si OPSCC patients. t tests were used to compare continuous variables; χ 2 or Wilcoxon rank‐sum tests were used to compare nonparametric categorical variables. Results Seventy‐eight patients underwent SP TORS. The bleed rate was 5.1%, mortality rate was 2.6%, and conversion rate was 0%. Compared to the Si cohort, OPSCC patients undergoing TORS SP procedures saw no significant differences in operative time or post‐TORS bleeds ( P > .05). Conclusions The SP is a comparably safe surgical instrument. Overall learning curve for the SP was rapid among experienced TORS surgeons.

6095 Background: Prognosis for patients (pts) with locally-advanced, HPV-positive oropharynx squamous cell carcinoma (HPV+OPSCC) is significantly better than for pts with HPV-negative head and neck squamous cell carcinoma (HNSCC). Historic survival of pts with metastatic HNSCC is 6-9 months with palliative therapy. However, the prognosis and survival of pts with HPV+OPSCC with distant metastases is not known. Methods: Pts with HPV+OPSCC with distant metastatic disease were identified from databases from the departments of surgery, radiation, and medical oncology. Demographic and clinical data was abstracted from the medical record. All pts had confirmed HPV/p16+ disease. Results: Fifteen pts with metastatic HPV+ OPSCC were identified. The median age was 57 years (range 42-78, 15 male). The median pack-year smoking was 0 (range 0-120). Primary site included 10 tonsil and 5 tongue base. At diagnosis, one pt had stage III and 14 had stage IV disease (IVA: 9, IVB: 2, IVC: 3). T- and N-stage included T1 (1), T2 (10), T3 (3), T4 (1) and N1 (1), N2a (1), N2b (9), N2c (3), N3 (1). Extracapsular extension was seen in 8 pts, absent in 2, and unknown in 5. Seven pts had lymph node (LN) involvement at level IV/V. Initial therapy for locally-advanced disease included surgery followed by adjuvant radiation (RT) in 1 pt and chemoRT in 8, and definitive chemoRT in 3 pts. Three pts were metastatic at initial diagnosis. Of 6 pts with an isolated metastatic site, 3 pts are alive > 2 years from diagnosis of metastasis (median 1.97 years, range 0.49-2.29). Palliative therapy included surgery (3), RT (9), platinum chemo +/- cetuximab (8), cetuximab alone (2) or with a taxane (2). The most common sites of metastasis included bone (6), lung (5), and LNs (5). The 1-year survival rate after diagnosis of metastatic disease was 92%. The median time to diagnosis of metastatic disease after definitive therapy was 0.47 years (95% CI 0.19-1.29); 75% of pts who developed metastatic disease did so within 1 year of definitive therapy. Of note, 2 of the 15 pts developed a secondary immune-mediated malignancy (melanoma and non-HIV associated Kaposi’s sarcoma). Conclusions: The survival of pts with metastatic HPV+OPSCC is significantly better than that of historic controls.

A case is presented showcasing the feasibility of three‐dimensional (3D) printing patient‐specific fistula plugs as a bridge therapy to definitive management of pharyngocutaneous fistulae. For this patient, a set of 3D printed fistula plugs was successfully used with low morbidity and positive results in the management of this postoperative issue. Utilizing 3D printed fistula plugs could represent a novel yet safe therapy for patients requiring long‐term management of similar wounds. Further studies are warranted to evaluate implementation of this practice on a widespread scale. Laryngoscope, 131:111–114, 2021

AbstractObjective The objective of this study is to describe the clinical presentation, tumor characteristics, natural history, and treatment patterns of sinonasal osteosarcoma.Methods Fourteen patients who had been treated for osteosarcoma of the nasal cavity and paranasal sinuses at a tertiary care center were reviewed. In addition, a systematic review of the literature for osteosarcoma of the sinonasal cavity was performed.Results In a systematic review, including 14 patients from the authors' institution, 53 total studies including 88 patients were assessed. Median follow-up was 18 months (interquartile range: 8–39 months). The most common presenting symptoms were facial mass or swelling (34%), and nasal obstruction (30%). The most common paranasal sinus involved by tumor was the maxillary sinus (64%), followed by the ethmoid sinuses (52%). The orbit (33%), dura (13%) and infratemporal fossa (10%) were the most common sites of local invasion. The majority of patients underwent surgery followed by adjuvant therapy (52.4%). Increasing age was associated with decreased overall survival rate (unit risk ratio [95% confidence interval (CI)] = 1.02 [1.003–1.043]; p = 0.0216) and T4 disease was associated with decreased disease-specific survival rate (hazard ratio [HR] = 2.87; p = 0.0495). The 2- and 5-year overall survival rates were 68 and 40%, respectively, while 2- and 5-year disease-specific survival rates were 71% and 44%, respectively.Conclusion Sinonasal osteosarcomas are uncommon tumors and can pose a significant therapeutic challenge. Increasing age and T4 disease are associated with worse prognosis. This disease usually warrants consultation by a multidisciplinary team and consideration of multimodality therapy.

ObjectivesTo assess the outcomes of abdominal dermal‐fat grafting following superficial and total parotidectomy.MethodsA retrospective chart review of parotidectomy patients was performed. Patients were divided into four groups based on surgical extent and grafting status: superficial parotidectomy (SP), superficial parotidectomy with grafting (SPg), total parotidectomy (TP), and total parotidectomy with grafting (TPg). Complication rates and operative times were then compared between surgically matched groups (SP vs. SPg, TP vs. TPg). Complications included graft necrosis, gustatory sweating, first‐bite syndrome, infection, hematoma, sialocele, and seroma. Data was analyzed via chi‐square and two‐sample t testing, logistic regression, and one‐way analysis of variance.ResultsThe cohort consisted of 330 patients: 106 SP (32.12%), 61 SPg (18.48%), 82 TP (24.85%), and 81 TPg (24.55%). No donor site complications occurred. TPg resulted in seven graft necroses (8.64%), and 22 reported gustatory sweating (27.20% vs. 10 TP patients (12.2%), P = 0.016); SPg resulted in two necroses (3.28%). There were no other statistically significant differences in complication rates. Graft recipients receiving adjuvant radiation were more likely to develop necrosis (odds ratio [OR] 4.60, 95% confidence interval [CI], 1.16–18.27, P = .0194). Patients who developed gustatory sweating were 8.38 years younger (95% CI 2.66–14.10, P = 0.002, follow‐up time > 48 days). Grafting did not increase operative times (TP/TPg: mean = 275.91/263.65 minutes, standard error of the mean = 41.96/33.75, P = 0.822).ConclusionAn abdominal dermal‐fat graft is an excellent reconstructive choice for a parotidectomy defect and is not associated with increased complication rates or prolonged operative time.Level of Evidence4 Laryngoscope, 130:2144–2147, 2020

The aim of this retrospective study was to describe the oncologic and functional results of treating oropharyngeal squamous cell carcinoma with transoral robotic surgery and neck dissection as monotherapy. A review was performed, including all patients who underwent transoral robotic surgery and neck dissection as the only means of therapy for oropharyngeal carcinoma from March 2007 to July 2009 at a single tertiary care academic medical center. We reviewed all cases with ≥ 24-month follow-up. Functional outcomes included tracheostomy dependence and oral feeding ability. Oncologic outcomes were stratified by human papillomavirus (HPV) status and tobacco use and included local, regional, and distant disease control, as well as disease-specific and recurrence-free survival. Eighteen patients met study criteria. Ten patients (55.6%) were able to eat orally in the immediate postoperative period, and 8 (44.4%) required a temporary nasogastric tube for a mean duration of 13.6 days (range 3 to 24 days) before returning to an oral diet. No patient required placement of a gastrostomy tube, and all patients are tracheostomy-tube–free. Among the HPV-positive nonsmokers (12/18, 66.7%), Kaplan-Meier estimated 3-year local, regional, and distant control rates were 90.9%, 100%, and 100%, respectively. Kaplan-Meier estimated disease-specific survival and recurrence-free survival were 100% and 90.9%, respectively. No complications occurred.
