Аннотация
OBJECTIVE: High-dose radiation therapy affects bone metabolism, and therefore post-radiotherapy bone formation is an uncommon finding. This case describes an unusual ossification in the maxillary region identified after head and neck radiotherapy.
RESULTS: A 45-year-old female patient was submitted to maxillary surgical resection and orbital exenteration due to squamous cell carcinoma. Radiotherapy post-surgery was performed because of compromised surgical margins. After 4 months of the conclusion of radiotherapy, the patient presented a bone exposition at surgical site. Surprisingly, the oral examination and computed tomography revealed a new formation of the right palatine vault and bone formation filling the nasal and orbital cavity. The incisional biopsy discarded residual disease or osteoradionecrosis and showed normal tissue.
CONCLUSIONS: To the best of the authors' knowledge, this is the first case of wide bone formation as an early effect of head and neck radiotherapy.
