Identifying predictors of HPV-related head and neck squamous cell carcinoma progression and survival through patient-derived models.

Therapeutic innovation for human papilloma virus-related (HPV+) head and neck squamous cell carcinomas (HNSCCs) is impaired by inadequate preclinical models and the absence of accurate biomarkers. Our study establishes the first well-characterized panel of patient-derived xenografts (PDXs) and organoids from HPV+ HNSCCs while determining fidelity of the models to the distinguishing genetic features of this cancer type. Despite low engraftment rates, whole exome sequencing showed that PDXs retain multiple distinguishing features of HPV+ HNSCC lost in existing cell lines, including PIK3CA mutations, TRAF3 deletion and the absence of EGFR amplifications. Engrafted HPV+ tumors frequently contained NOTCH1 mutations, thus providing new models for a negatively prognostic alteration in this disease. Genotype-phenotype associations in the models were then tested for prediction of tumor progression and survival in published clinical cohorts. Observation of high tumor mutational burdens (TMBs) in the faster-growing models facilitated identification of a novel association between TMB and local progression in both HPV+ and HPV- patients that was prognostic in HPV- cases. In addition, reduced E7 and p16INK4A levels found in a PDX from an outlier case with lethal outcome led to detection of similar profiles among recurrent HPV+ HNSCCs. Transcriptional data from the Cancer Genome Atlas was used to demonstrate that the lower E2F target gene expression predicted by reduced E7 levels has potential as a biomarker of disease recurrence risk. Our findings bridge a critical gap in preclinical models for HPV+ HNSCCs and simultaneously reveal novel potential applications of quantifying mutational burden and viral oncogene functions for biomarker development.

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.

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.

Transoral Robotic Surgery with Sialendoscopy for a Plunging Ranula.

BACKGROUND/AIMS: Plunging ranulas are oral mucoceles that often cannot be visualized directly and thus can be challenging to diagnose and differentiate from other neck lesions. Surgery is the preferred treatment option, but the optimal approach requires careful consideration. METHODS: We report the case of a plunging ranula presenting as an isolated neck mass in a 33-year-old patient. This patient was treated with a novel transoral robotic surgery (TORS)-assisted approach aided by sialendoscopy. RESULTS: TORS allowed for exceptional visualization and access to the plunging ranula and sublingual gland while avoiding critical neurovascular structures. The patient healed well without recurrence or complications. CONCLUSION: The TORS approach with sialendoscopy for plunging ranulas described in this case report shows promise and should be considered for certain clinical presentations. Additional studies evaluating the effectiveness of TORS for plunging ranulas may be indicated.

Post-treatment weight change in oral cavity and oropharyngeal squamous cell carcinoma.

PURPOSE: Incidence of head and neck cancer (HNC) due to human papillomavirus (HPV) infection has been increasing. Treatment regimens have evolved. These changes might result in alterations of assumed treatment-related weight changes for HNC patients. We aimed to compare the trajectory of pre- to post-treatment weight changes of oropharyngeal squamous cell carcinoma (OPSCC) versus oral cavity squamous cell carcinoma (OCSCC) patients and to compare weight changes between patients with primary surgery ± adjuvant therapy to patients with primary radiation and/or chemotherapy. METHODS: This retrospective cohort study examined adult OPSCC and OCSCC patients with initial definitive treatment at the University of Pennsylvania from January 1, 2009 to December 31, 2010. Patient demographics, medical history, treatments, and pre- and post-treatment body weight data were collected from electronic medical records. Mixed-effects modeling was performed. RESULTS: Among 354 patients who met the inclusion criteria, 290 (82 %) survivors were available for inclusion by 24-month follow-up. More than 70 % OPSCC and OCSCC patients were overweight or obese at all pre- and post-treatment time points. The average weight among OPSCC patients was 6.63 kg higher than OCSCC patients at all time points (mean = 6.63, 95 % confidence interval (CI), 2.46-10.79, p = 0.002). After adjusting for potential confounders, patients with primary surgery had significantly more weight gain from pre-treatment to 12-18 month post-treatment follow-up as compared to patients with primary radiation and/or chemotherapy (adjusted mean = 4.01, 95 % CI, 0.16-7.87, p = 0.041). CONCLUSION: Overweight and obesity may be a new challenge in OPSCC and OCSCC patient care. Further study is needed to evaluate whether exercise and nutritional interventions can improve their survivorship.

Cribriform adenocarcinoma of the tongue and minor salivary gland: transoral robotic surgical resection.

BACKGROUND/AIMS: Cribriform adenocarcinoma of the tongue and minor salivary gland (CATMSG) is a rare, locally invasive, and poorly recognized tumor, typically occurring on the base of the tongue. This case report describes the previously unreported use of transoral robotic surgery (TORS) for the local resection of CATMSG in a novel location, the palatine tonsil, and leverages follow-up information to compare TORS to conventional surgical approaches. METHODS: We performed transoral radical tonsillectomy, limited pharyngectomy, and base-of-tongue resection with staged left selective neck dissection. RESULTS: Tumor pathology revealed an infiltrating salivary gland carcinoma with perineural invasion and a histologically similar adenocarcinoma in 1 of 64 left neck lymph nodes. TORS was performed with no perioperative complications, and the patient was subsequently discharge on postoperative day 3 with a Dobhoff tube. Postoperatively, the Dobhoff tube was removed at 1 month, the patient was advanced to soft foods by mouth at 2 months, and 3-month positron emission tomography-computed tomography scan showed no evidence of distant metastases and evolving postsurgical changes in the left tonsillectomy bed. CONCLUSIONS: This case report highlights the use of TORS resection with minimal acute and long-term morbidity compared to conventional approaches for the resection of this rare, locally invasive salivary gland carcinoma in the palatine tonsil.

The University of Pennsylvania curriculum for training otorhinolaryngology residents in transoral robotic surgery.

PURPOSE: To define a curriculum for the development of robotic surgical skills in otorhinolaryngology residency training. METHODS: A systematic review of the current literature on robotic surgery training was performed. Based on prior reports in other specialties, a curriculum for otorhinolaryngology residents was created that progresses through several modules, including didactics, inanimate skills laboratory, and operative experience. RESULTS: The curriculum for residents in otorhinolaryngology was designed as follows: didactics include an overview of the robotic device and instruments, a tutorial in basic controls and function, and a room setup and positioning. The anatomy and steps of transoral procedures are taught through books, videos, operative observations, and cadaver dissections. Skills are developed with a virtual reality robotic simulator and robotics labs. The operative experience progresses from case observation to bedside assistant to console surgeon. The role of the console surgeon progresses in a stepwise fashion, and the procedures of radical tonsillectomy, supraglottic partial laryngectomy, and base of tongue resection have been organized as a series of steps. CONCLUSION: A structured curriculum for training residents in transoral robotic surgery was developed. This training is important for otorhinolaryngology residents to acquire the knowledge and skills to perform robotic surgery safely.

Transoral robotic surgery with free flap reconstruction: Functional outcomes of 241 patients at a single institution.

BACKGROUND: Transoral robotic surgery (TORS) for oropharyngeal malignancy optimizes oncologic outcomes while preserving functionality. This study identifies patterns of functional recovery after TORS with free flap reconstruction (FFR). METHODS: Retrospective cohort study at a tertiary care center of patients with primary oropharyngeal tumors treated with TORS with FFR between 2010 and 2022. Patients were categorized into: adjuvant chemoradiation or radiation, or no adjuvant therapy (NAT). Functional outcomes were measured by functional oral intake scale (FOIS). RESULTS: 241 patients were included. FOIS declined at first postoperative appointment (median = 7.0 to 2.0, IQR = [7.0, 7.0], [2.0, 4.0]), and progressively improved to 6.0 (5.0, 6.0) after 1 year, with NAT having the highest FOIS (7.0, p < 0.05). Predictors of poor long-term FOIS included RT and hypoglossal nerve (CN XII) involvement (p < 0.05). CONCLUSIONS: TORS with FFR leads to good long-term function with minimal intake restrictions. Radiation therapy and CN XII involvement increase risk of worse functional outcomes.

Transoral robotic surgery in head and neck cancer: what radiologists need to know about the cutting edge.

The evolution of oncologic surgical technology has moved toward reducing patient morbidity and mortality without compromising oncologic resection or oncologic outcomes. The goals in treating head and neck cancer are to cure patients, as well as to provide quality of life by improving functional and social outcomes through organ-preservation therapies, which may include surgery, chemotherapy, and/or radiation therapy. Transoral robotic surgery (TORS) is an emerging technique that provides several benefits over existing treatment regimens and over open surgery for head and neck cancer, including reductions in operative times, blood loss, intensive care unit stays, and overall duration of patient hospitalization. Transoral robotic techniques allow wide-view, high-resolution, magnified three-dimensional optics for visualization of the mucosal surfaces of the head and neck through an endoscope, while avoiding the extensive external cervical incisions often required for open surgeries. Radiologists play an important role in the successful outcome of these procedures, both before and after TORS. Determining a cancer patient's surgical candidacy for TORS requires a thorough preoperative radiologic evaluation, coupled with clinical and intraoperative assessment. Radiologists must pay particular attention to important anatomic landmarks that are clinical blind spots for surgeons. Knowledge of the expected postoperative imaging appearances, so that they can be distinguished from recurrent disease and second primary tumors, is essential for all radiologists involved in the care of these patients.

Fluorodeoxyglucose-induced allergic reaction: a case report.

The number of diagnostic positron emission tomography/computed tomography (PET/CT) procedures performed in the USA and worldwide is rapidly increasing. Although the benefits of these procedures are obvious, the increasing use of radiopharmaceuticals requires a better understanding of potential adverse affects and their proper management. We present herein the first report of an allergic reaction to fluorodeoxyglucose in the setting of repeated PET/CT scans for restaging purposes in a patient with pyriform sinus cancer.

Functional Outcomes in Patients with Human Papillomavirus-Associated Oropharyngeal Squamous Cell Cancer Treated with Trimodality Therapy.

OBJECTIVES: To describe swallowing and feeding-tube outcomes in patients with high-risk oropharyngeal cancer treated with trimodality therapy (TMT), including transoral robotic surgery (TORS) and adjuvant chemoradiotherapy. METHODS: A chart review was conducted on patients with HPV+ OPSCC receiving TMT with TORS at an academic medical center from March 2010 to March 2021. Data collected included demographics, treatment, feeding tube placement, functional oral intake scale (FOIS) scores, and swallowing-language pathology (SLP) evaluations. RESULTS: A total of 255 patients met selection criteria (mean age 61 years, 88% male). Following intraoperative nasogastric tube (NG) placement, 31% remained NG tube dependent after 3 weeks. A gastrostomy tube was placed in 19% of patients, and at 1 year after end-of-treatment (EOT), 3.5% overall remained tube-dependent. Mean FOIS scores were 6.9 (SD = 0.3) at pre-operative visit, 2.6 (1.8) at first post-operative visit, and 5.5 (1.5) after EOT. In the subset of patients with follow-up longer than 2 years (n = 118), the mean FOIS was 6.1 (SD = 1.3) at most recent visit. Clinical signs of aspiration/penetration were suspected on SLP evaluation in 18% of patients. These patients were subsequently evaluated with fiberoptic endoscopic evaluation of swallowing (FEES) and/or barium swallow study, which confirmed signs of aspiration in 2.7% of patients overall. Delayed NG tube removal after 3 weeks was predictive of (1) gastrostomy tube requirement and (2) clinical signs of aspiration on an SLP visit after EOT. CONCLUSIONS: Favorable functional and feeding-tube outcomes are demonstrated in patients with HPV-associated OPSCC undergoing TMT. In this single-institution study, we found low rates of long-term feeding tube dependence and high median FOIS following treatment. Review of routine SLP visits provides a detailed and easily accessible means for assessing swallowing function in this cohort. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:3013-3020, 2023.

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.

Transoral robot-assisted lingual tonsillectomy and uvulopalatopharyngoplasty for obstructive sleep apnea.

OBJECTIVES: We assessed the use of transoral robot-assisted lingual tonsillectomy and uvulopalatopharyngoplasty for the surgical management of tongue base obstruction in patients with obstructive sleep apnea. METHODS: In a prospective, nonrandomized trial using historical controls, patients underwent drug-induced sleep endoscopy, transoral robot-assisted lingual tonsillectomy with uvulopalatopharyngoplasty, and preoperative and postoperative polysomnography. RESULTS: Twenty patients have completed the study to date. The rate of surgical success was 45%, and the rate of surgical response was 65%. The mean preoperative apnea-hypopnea index of 55.6 decreased by 56.7%, to a mean postoperative value of 24.1 (p < 0.001), and the minimum arterial oxygen saturation increased from the mean preoperative value of 75.8% to the mean postoperative value of 81.7% (p = 0.013). The mean Epworth Sleepiness Scale score improved from 13.4 to 5.9 (p = 0.003). One patient had postoperative bleeding that required cauterization, resulting in a major complication rate of 4.2%. CONCLUSIONS: Transoral robot-assisted lingual tonsillectomy with uvulopalatopharyngoplasty is a novel technique for the surgical management of obstructive sleep apnea that results in a significant decrease in the apnea-hypopnea index, a significant improvement in minimum arterial oxygen saturation, and a significant improvement in the Epworth Sleepiness Scale score and has an acceptable complication rate.

Molecular identification of an ETV6-RET fusion in a secretory carcinoma associated with a pleomorphic adenoma.

Pleomorphic adenoma (PA) is the most common neoplasm of the salivary glands. Although several carcinomas have been reported to arise from PA, only 1 case of salivary gland secretory carcinoma (SC) ex pleomorphic adenoma has been previously reported. SC is a newly described salivary gland tumor harboring an ETV6-NTRK3 translocation, which is classically observed in secretory carcinoma of the breast, although other translocations have recently been observed. We report the first case of the molecular identification of a rare ETV6-RET translocation in an SC arising from a PA in the submandibular salivary gland (SC ex PA). Our results add to the diversity of tumors that are associated with PA and contribute to the molecular characterization of SC, which will have implications on its diagnosis, prognosis, and treatment.

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.

Phase II Randomized Trial of Transoral Surgery and Low-Dose Intensity Modulated Radiation Therapy in Resectable p16+ Locally Advanced Oropharynx Cancer: An ECOG-ACRIN Cancer Research Group Trial (E3311).

PURPOSE: Definitive or postoperative chemoradiation (CRT) is curative for human papillomavirus-associated (HPV+) oropharynx cancer (OPC) but induces significant toxicity. As a deintensification strategy, we studied primary transoral surgery (TOS) and reduced postoperative radiation therapy (RT) in intermediate-risk HPV+ OPC. METHODS: E3311 is a phase II randomized trial of reduced- or standard-dose postoperative RT for resected stage III-IVa (American Joint Committee on Cancer-seventh edition) HPV+ OPC, determined by pathologic parameters. Primary goals were feasibility of prospective multi-institutional study of TOS for HPV+ OPC, and oncologic efficacy (2-year progression-free survival) of TOS and adjuvant therapy in intermediate-risk patients after resection. TOS plus 50 Gy was considered promising if the lower limit of the exact 90% binomial confidence intervals exceeded 85%. Quality of life and swallowing were measured by functional assessment of cancer therapy-head and neck and MD Anderson Dysphagia Index. RESULTS: Credentialed surgeons performed TOS for 495 patients. Eligible and treated patients were assigned as follows: arm A (low risk, n = 38) enrolled 11%, intermediate risk arms B (50 Gy, n = 100) or C (60 Gy, n = 108) randomly allocated 58%, and arm D (high risk, n = 113) enrolled 31%. With a median 35.2-month follow-up for 359 evaluable (eligible and treated) patients, 2-year progression-free survival Kaplan-Meier estimate is 96.9% (90% CI, 91.9 to 100) for arm A (observation), 94.9% (90% CI, 91.3 to 98.6]) for arm B (50 Gy), 96.0% (90% CI, 92.8 to 99.3) for arm C (60 Gy), and 90.7% (90% CI, 86.2 to 95.4) for arm D (66 Gy plus weekly cisplatin). Treatment arm distribution and oncologic outcome for ineligible or step 2 untreated patients (n = 136) mirrored the 359 evaluable patients. Exploratory comparison of functional assessment of cancer therapy-head and neck total scores between arms B and C is presented. CONCLUSION: Primary TOS and reduced postoperative RT result in outstanding oncologic outcome and favorable functional outcomes in intermediate-risk HPV+ OPC.

Reconstruction of complex total parotidectomy defects using the free anterolateral thigh flap: a classification system and algorithm.

BACKGROUND: Composite defects resulting from total parotidectomy present unique reconstructive challenges. This study reviews our experience using the anterolateral thigh (ALT) flap with adjacent fascia and nerve grafts to reconstruct these defects, and establishes a classification system and treatment algorithm that simplifies reconstruction. METHODS: Between July 2005 and November 2009, 22 patients underwent total parotidectomy and immediate reconstruction with the extended ALT flap. Of total, 21 patients had concomitant neck dissection. Defects were classified as follows: Type I, significant soft-tissue loss (n = 4); Type II, significant soft-tissue loss with facial nerve excision (n = 2); Type III, significant soft-tissue loss with resection of surrounding bone(s) (n = 5); and Type IV, significant soft-tissue loss, bone resection, and facial nerve excision (n = 11). Reconstruction procedures included free ALT (n = 9); ALT with fascia lata sling (n = 4); ALT with nerve grafting (n = 5); and ALT, fascia lata sling, and nerve grafting (n = 4). Complications, functional outcome, and patient satisfaction were assessed by chart review and prospective surveys. RESULTS: Fourteen of 22 patients participated in surveys. There was 1 flap loss. Donor site complications included the following: 4 patients (29%) with minor numbness of the lateral thigh skin, and 1 (7%) seroma. There was no leg weakness or infection. Recipient site morbidity included 2 patients (14%) with Frey syndrome, 3 (21%) with delayed wound healing, 5 (36%) with facial numbness, and 5 with mild oral incompetence. Smile asymmetry was present in 7 patients (50%). Ten patients (71%) reported being "very happy" with their appearance. CONCLUSIONS: The ALT flap, used with adjacent nerve and fascia, offers a versatile option for reconstructing complex parotidectomy defects. The procedure involves minimal donor site morbidity, and results in sound functional outcomes and high degrees of patient satisfaction.

Postoperative adjuvant therapy after transoral robotic resection for oropharyngeal carcinomas: rationale and current treatment approach.

The advancement of transoral surgical techniques for the management of oropharyngeal carcinomas has raised questions about how adjuvant therapy can best be integrated. Some of these questions have come from the application of established oncologic principles of adjuvant therapy, and some are unique to the evolving experience with transoral surgery and in particular with the recent advancement of robotic surgery. It is important for all members of the multidisciplinary treatment team to have a clear understanding of the foundation for adjuvant therapy and the issues unique to transoral robotic surgery to provide optimal patient care as this new treatment paradigm gains popularity for its safe application.

Voice Restoration after Radiation and Supracricoid Partial Laryngectomy by Injection Augmentation of the Arytenoid.

Supracricoid partial laryngectomy (SCPL) is an organ-preserving surgical technique intended to achieve oncologic control of laryngeal cancer while maintaining laryngeal functions. Most patients who undergo SCPL achieve a serviceable voice. However, several factors can affect the function of the neoglottis after SCPL. We report the case of a 53-year-old male referred for near aphonia after undergoing SCPL for recurrent laryngeal carcinoma initially treated with radiation. Calcium hydroxylapatite injection augmentation of the right arytenoid was performed to assist neoglottic closure. Flexible laryngoscopy demonstrated greatly improved neoglottic closure postoperatively, and the patient's voice was successfully restored. This case demonstrates a novel technique for voice restoration in patients who have undergone partial laryngectomy.
