Arnaud F. Bewley

About

Arnaud F. Bewley, M.D., is the Chair of the Department of Otolaryngology, Director of the Division of Head & Neck Surgery, and a Professor in the Department of Otolaryngology at UC Davis Health. He is a fellowship-trained head and neck cancer and reconstructive surgeon whose practice focuses on the comprehensive management of tumors of the head and neck, including benign and malignant tumors of the face, mouth, throat, neck, and thyroid. Dr. Bewley has a special interest in utilizing microvascular free-flap techniques to optimize patients' post-operative appearance and function. His research interests include designing treatment protocols for advanced skin cancers to improve cure rates and reduce side effects, employing minimally invasive transoral robotic surgery to remove head and neck tumors, and analyzing the cost of care for head and neck cancer to promote cost-effective healthcare resource utilization. He is also involved in developing novel simulation training for residents in managing acute and emergency clinical scenarios. Dr. Bewley's background includes a B.A. in Physics from Yale University, an M.D. from Columbia University, and specialized training through internships, residencies, and fellowships at institutions such as the University of Pennsylvania, University of South Carolina, and Medical University of South Carolina.

• Intraoperative Margin Assessment in Oral and Oropharyngeal Cancer Using Label-Free Fluorescence Lifetime Imaging and Machine Learning

  IEEE Transactions on Biomedical Engineering · 2020 · 88 citations

  OBJECTIVE: To demonstrate the diagnostic ability of label-free, point-scanning, fiber-based Fluorescence Lifetime Imaging (FLIm) as a means of intraoperative guidance during oral and oropharyngeal cancer removal surgery. METHODS: FLIm point-measurements acquired from 53 patients (n = 67893 pre-resection in vivo, n = 89695 post-resection ex vivo) undergoing oral or oropharyngeal cancer removal surgery were used for analysis. Discrimination of healthy tissue and cancer was investigated using vario…

• The Impact of COVID‐19 on Head and Neck Cancer Treatment: Before and During the Pandemic

  OTO Open · 2021 · 49 citations

  OBJECTIVES: To describe the impact that the coronavirus disease 2019 (COVID-19) pandemic had on the presentation of patients with head and neck cancer in a single tertiary care center. STUDY DESIGN: Retrospective cohort study. SETTING: Academic institution. METHODS: We performed a retrospective review of patients with newly diagnosed head and neck squamous cell carcinoma (HNSCC) who presented as new patients between September 10, 2019, and September 11, 2020. Patients presenting during the 6 mon…

• Intraoperative delineation of p16+ oropharyngeal carcinoma of unknown primary origin with fluorescence lifetime imaging: Preliminary report

  Head & Neck · 2022 · 27 citations

  BACKGROUND: This study evaluated whether fluorescence lifetime imaging (FLIm), coupled with standard diagnostic workups, could enhance primary lesion detection in patients with p16+ head and neck squamous cell carcinoma of the unknown primary (HNSCCUP). METHODS: FLIm was integrated into transoral robotic surgery to acquire optical data on six HNSCCUP patients' oropharyngeal tissues. An additional 55-patient FLIm dataset, comprising conventional primary tumors, trained a machine learning classifi…

• Stratification of surgical margin distances by the millimeter on local recurrence in oral cavity cancer: A systematic review and <scp>meta‐analysis</scp>

  Head & Neck · 2023-03-09 · 26 citations

  reviewOpen access

  Abstract There are limited data supporting the commonly suggested 5 mm margin cutoff as the optimum value in defining clear margins in oral cancer. A database search of Pubmed/Medline, Web of Science, and EBSCOhost was performed from inception to June 2022. A random‐effects model was chosen for this meta‐analysis. The Preferred Reporting Items for Systematic Reviews and Meta‐analyses (PRISMA) guidelines were followed throughout this study. Seven studies met study criteria (2215 patients). The ri…

• Advanced head and neck surgery training during the <scp>COVID</scp>‐19 pandemic

  Head & Neck · 2020 · 26 citations

  BACKGROUND: The COVID-19 pandemic has significantly impacted medical training. Here we assess its effect on head and neck surgical education. METHODS: Surveys were sent to current accredited program directors and trainees to assess the impact of COVID-19 on the fellow's experience and employment search. Current fellows' operative logs were compared with those of the 2018 to 2019 graduates. RESULTS: Despite reduction in operative volume, 82% of current American Head and Neck Society fellows have…
