Study of Epithelial Migration in the Tympanic Membrane and Bony External Auditory Canal Wall in Patients With Irradiated Nasopharyngeal Carcinoma

摘要

Objective The objectives of this study were to determine the presence of epithelial migration in patients with postirradiated nasopharyngeal carcinoma (NPC) and to compare the rate of epithelial migration in the tympanic membrane (TM) and the bony external auditory canal (EAC) of postirradiated NPC ears with normal ears by means of the ink dot method.
