Resumo: Objective: Describe 21 cases of osteoradionecrosis (ORN) in patients undergoing radiotherapy in the head and neck region.
Study Design: ORN cases diagnosed between January 2010 and December 2020 in a southern Brazil hospital were selected. ORN demographic data and clinical features were collected.
Results: Men (n=16/76.2%) with a mean age of 60.9 (34.5;70.9) years were more affected. The tumor's primary sites were the mouth (n=12), oropharynx (n=7), hypopharynx (n=1), and skin (n=1), with Squamous Cell Carcinoma (n=19), Cystic Adenoid Carcinoma (n=1), and Adenocarcinoma (n=1) diagnoses. The mandible was the most affected location (n=19/90.48%), with an average time of ORN development of 60.9 (2.1;80.3) months after radiotherapy treatment. In 13 (61.9%) patients, post-radiotherapy tooth extractions were performed and were considered the triggering factor.
Conclusion: ORN is more common in the mandible of male patients undergoing tooth extraction after radiotherapy. Dental evaluation prior to radiotherapy treatment is necessary to minimize ORN development.
