Success of preventive approach to mandibular osteoradionecrosis in an adolescent: case report.

Abstract

Osteoradionecrosis (ORN) is defined as the presence of ulceration or necrosis of the mucosa with exposure of necrotic bone that does not heal within a 2-month period after radiotherapy in patients with head and neck tumours. The mandible presents a higher risk of developing ORN than the maxilla and extraction of teeth is also considered a risk factor for the development of ORN. The aim of this article was to present a clinical case where a protocol was used to prevent the development of ORN after the extraction of lower molars in an adolescent who had undergone surgical removal and radiotherapy for a mucoepidermoid carcinoma in the left parotid gland. The results showed that the protocol used was efficient in the prevention of osteoradionecrosis in this adolescent. One year after the extractions, no clinical or radiographic signs of any pathological alteration were observed in the region; the patient remains under periodical clinical and radiographic follow-up.Oral Surgery 10 (2017) e104--e109.
