To clarify the actual condition of middle ear diseases in cleft palates and the relationship between middle ear disease and Eustachian tube function, otological examinations and tests for Eustachian tube function were carried out in 100 patients with repaired cleft palates. The following findings were obtained: 1) cleft palates showed the abnormal ear drums in 87.9%; 2) hearing loss was found in 37.0% of the ears and abnormal tympanograms were found in 50.8% of the ears, both hearing loss and abnormal tympanograms tended to decrease until the age of 7-8 years; 3) Eustachian tube function was frequently abnormal in younger children, but it tended to improve at 7-8 years of age; 4) hearing loss and abnormal tympanograms were common in patients with abnormal Eustachian tube function.Thus, it was revealed that cleft palates had high incidence of middle ear diseases, and that Eustachian tube dysfunction was thought to be one of main causes of middle ear diseases in cleft palates. As severe middle ear diseases were found in cleft palates, though the frequency was not high, intensive otological care seemed to be necessary for cleft palate patients.
