Timing for Radiotherapy Initiation After Dental Extraction and Risk of Osteoradionecrosis in Head and Neck Cancer Patients: A Systematic Review and Meta‐Analysis

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Head and neck cancer (HNC) patients are advised to undergo dental extraction of teeth with poor prognosis prior to radiotherapy (RT) initiation to prevent osteoradionecrosis (ORN). However, insufficient healing time may result in persistent extraction wounds during RT, which constitute a potential risk factor for ORN, whereas ...
