[Otologic findings in adult patients with lip, jaw, palate clefts].

In a clinical study 27 adults with cleft lip and palate (mean age 21.9 years) were examined to look for long-term results of hearing and pathology of the tympanic membrane. 69.2% of the ears showed normal hearing; the threshold of mean hearing loss never exceeded the 20 dB-level. Slight changes of the tympanic membrane could be seen in 48.2%, severe changes in 16.7%.
