This article reports on 21 long-term (10 years) survivors of nasopharyngeal carcinoma, divided into 2 groups: those subjected to an inflation-deflation test and a clearance function test in a longitudinal study, and those receiving sonotubometry in a cross-sectional study. On the inflation-deflation test, 12 (55%) out of 22 ears had a patulous eustachian tube, and on sonotubometry, 10 (50%) out of 20 ears also revealed a patulous eustachian tube. Except for 4 ears with chronic otitis media, the ears had resolved to a normal eardrum appearance at 10 years postirradiation. The phenomenon might be attributed to both restoration of the impaired tubal function and the development of a patulous tube.
