Cleft palate is one of the most common congenital anomalies, which is usually accompanied by conductive hearing loss due to middle ear effusion. Early detection and treatment are important for proper development of the speech. In managing the cleft palate patients, combined approaches including surgical correction, speech therapy and orthodontic management are necessary. Authors reviewed 120 patients who had undergone operations at the otolaryngologic department of the Seoul National University Hospital, from Aug. 1983 to Apr. 1991. We investigated various factors such as age, sex, type of cleft palate, method of operation, postoperative complications, method of revisional operation, frequency of the associated middle ear effusion. The results were as follows : 1) The ratio of child group(equal or lower than 15 years old) to adult group at the time of the operation was 2.08 : 1. 2) The ratio of male to female was 1 : 1.26. 3) The average age at the time of the initial operation was 4 years old in child group and 25 years old in adult group. 4) The types of cleft palate were secondary incomplete type in 84 cases(children 58 cases, adults 26 cases), submucosal type in 35 cases(children 22 cases, adults 13 cases) and one case was combined cleft palate and lip. 5) Types of operations were V-Y pushback palatoplasty in 95 cases, pharyngeal flap operation in 11 cases, 4-flap palatoplasty in 5 cases, double-Z plasty in 2 cases, combined pushback palatoplasty and pharyngeal flap operation in 6 cases and cheiloplasty in one case. 6) postoperative complications were necrosis of flap in one case, oronasal fistula in 2 cases, wound dehiscence in 2 cases, pharyngeal stenosis after pharyngeal flap operation in 4 cases and incomplete correction in 14 cases. Two cases had defect repair due to fistula and 14 cases had pharyngeal flap operation due to velopharyngeal incompetence. 7) Among 93 cases that had tympanometry, 52 were both ""A"" type(children 23 cases, adults 29 cases), 27 were bilateral ""B"" or ""C"" type and 14 were unilateral ""B"" or ""C"" type.
