Radiation‐Induced Pharyngeal Necrosis and Cervical Spine Osteoradionecrosis in Patients With Oropharyngeal Squamous Cell Carcinoma

Radiation therapy with or without chemotherapy is commonly used as an adjunct or alternative to surgery for treating head and neck cancer (HNC). In rare cases, radiation-induced side effects such as posterior pharyngeal wall necrosis, fistula formation, and osteoradionecrosis (ORN) can lead to dangerous complications of the cervical spine (C-spine).
