A clinical study of 100 randomly selected cleft lip and/or palate adult patients, ages 14 to 77 years. Forty-nine out of 100 were otologically normal. Forty-two out of 100 were audiologically normal. A negative history of past ear disease is not an accurate screening method for abnormality. Auditory impairments (27 out of 58) suggesting a sensori-neural loss were found in relatively young adults. Is there a progressive degenerative sensori-neural hearing impairment in congenital cleft disease? Thirty-one out of 58 had conductive losses: these were correlated with the otologic findings on examination. Twenty-three out of 100 had had palatal pharyn-goplasty. The surgical procedure to reduce hypernasality probably does not aggravate the Eustachian tubal dysfunction.

Approximately 50 percent of the congenital cleft lip and/or palate adults continue to have ear problems, probably for their lifetime.
