OSTEORADIONECROSIS AND CHOLESTEATOMA OF EXTERNAL AUDITORY CANAL IN POSTRADIOTHERAPY NASOPHARYNGEAL CARCINOMA PATIEN


ABSTRACT: Osteoradionecrosis and cholesteatoma of the external auditory canal following external-beam radiotherapy as the treatment of nasopharyngeal carcinoma is a rarely found complication. Patients with external auditory canal cholesteatoma (EACC) typically present with chronic otorrhea and dull pain due to the local invasion of squamous tissue into the bony external audioty canal (EAC). Purpose: To remind ENT specialists and general practitioners about the risk osteoradionecrosis and cholesteatoma of external auditory canal in nasopharyngeal carcinoma patient after radioteraphy treatment. Case: We report a case of osteoradionecrosis and
cholesteatoma of EAC in nasopharyngeal carcinoma (NPC) patient with complaint of a foul-smelling discharge from her right and left ears. Two years previously she had undergone external-beam radiotherapy to the neck as the treatment for nasopharyngeal carcinoma. Management: The cholesteatoma was removed microscopicaly on local anasthesia. After the cholesteatoma had been removed the right ear result of pure tone audiometry showed mild degree conductive hearing loss (27,7 dB), while the left ear within normal hearing threshold. Conclusion: Osteoradionecrosis and cholesteatoma of external auditory canal could develop as a complication ofradioteraphy in nasopharyngeal carcinoma patient.
