Philosophy of Care

I believe in taking time to build therapeutic relationships with my patients in order to effectively guide them through the often challenging and intense treatment necessary to combat head and neck tumors.

Clinical Interests

Dr. Arnaud Bewley 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. This primarily involves the surgical management of benign and malignant tumors of the face, mouth, throat, neck, and thyroid. He has a special interest in using microvascular free-flap techniques to reconstruct defects caused by tumor removal, in order to maximize a patient’s post-operative function.  

Research/Academic Interests

HPV+ tumors of the oropharynx: Developing and participating in protocols for de-escalation of treatment for HPV+ head and neck cancer

Transoral robotic surgery: Using minimally invasive transoral techniques to remove head and neck tumors and potentially avoid the toxicity of chemotherapy and radiation therapy.

Cost of  care for head and neck cancer: Identifying underlying factors contributing to increases in the cost of care for head and neck cancer patients and designing protocols that promote cost-effective utilization of health care resources.

Education & Simulation: Developing novel simulations to train residents in the management of acute and emergency clinical scenarios
