The ET function tests included passive opening, inflation-deflation, and clearance, and were performed before, at 6 months, and at 5 years after radiotherapy. The test results were found to be worst at 6 months after radiotherapy and improved at 5 years after radiotherapy. Tubal obstruction and inflammation are the main causes of the ET malfunction that results in otitis media with effusion (OME) in NPC patients after radiotherapy. Insertion of a ventilation tube into the ear with OME can relieve tubal obstruction but can aggravate inflammation. Thus, myringotomy and aspiration of effusion and local treatment may be preferable to insertion of a ventilation tube in NPC patients with OME. When hearing improvement in prolonged survival of NPC patients with OME is needed, the use of amplification is recommended. © 1995, SAGE Publications.
