Abstract
An hourglass or funnel-shaped, stenosed, external auditory meatus with a normal tympanic membrane, middle and inner ear is one of the congenital anomalies that occasionally occurs. Such abnormality was present in both ears of a woman and caused chronic otitis externa and deafness. A routine meatoplasty on the right ear failed because of an unusual cephalad position of the drumhead in relation to a "downhill" position of the stenosed outer meatus. Rerouting the ear canal to a horizontal position by removing bone of the canal superiorly, posteriorly, and inferiorly, and grafting the now horizontal canal with skin taken from the postauricular fold produced a good result. This is a satisfactory procedure for a woman, but would be cosmetically unacceptable for a man.
