Osteoradionecrosis of the mandible and mastoiditis after radiotherapy for parotid mucoepidermoid carcinoma.
Osteoradionecrosis of the mandible in conjunction with mastoiditis is an extremely rare occurrence following irradiation of salivary gland malignancy in the orofacial region. We report one such case of a patient who presented to us with trismus, jaw pain, and ear discharge. Imaging of the jaws revealed classical features of osteoradionecrosis and mastoiditis. This case is important because presenting features like trismus and dental infection led us to investigative procedures that revealed extensive bone involvement including mastoiditis. Trismus progressively increased over a period of 8 years. In this case, we would like to emphasize the importance of good oral hygiene in the postradiotherapy stage for head and neck cancer.
