Abstract
BACKGROUND: While almost all children with cleft palate develop eustachian tube dysfunction, this tends to normalize with age although it remains impaired in a number of patients. METHODS: Eustachian tube function was evaluated by tympanometry in 40 patients with an average age of 19.9 years. The number of patients with chronic otitis media, a sequelae of chronic eustachian tube dysfunction, was determined microscopically and from the patient's history. Hearing was assessed by pure tone RESULTS: Eustachian tube dysfunction was found bilaterally in 25% of the patients and unilaterally in 6%, while chronic otitis media was found in 32.5% and 12.5%, respectively. The hearing level did not differ between the side of the cleft and the opposite side (P=0.562). CONCLUSION: Nearly a third of the adult patients still suffered from eustachian tube dysfunction. Pathological tympanograms and chronic otitis media usually occurred bilaterally. A relationship between the side of the cleft and the side on which the eustachian tube dysfunction or its sequelae occurred was not apparent. The main reason seems to be the continuing bilateral muscular insufficiency in opening the eustachian tube.
