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.
