A clinico-statistical study was performed in 332 cases of cleft lip and palate in the past 20 years at the Department of Oral and Maxillofacial Surgery, Nara Medical University. The results were as follows: 1. The patients were 181 male s and 151 females, with a male to female ratio of 1.2: 1.2. Cleft morphology was classified as follows: cleft lip in 66 cases (19.9%), cleft lip and alveolus in 34 cases (10.2%), cleft lip and palate and/or alveolus in 127 cases (38.3%), cleft palate only in 69 cases (20.8%), submucous cleft palate only in 26 cases (7.8%), bifid uvula in 13 cases including cleft lip and/or alveolus in 4 cases.3. The laterality in clefts of lip, alveolus and p alate in 228 cases was unilateral in 178 cases (78.1%), bilateral in 49 cases (21.5%), and median in one case (0.4%). The laterality of these cases was the left side in 62.4%, and the right side in 37.6%, with a left to right side ratio of 1.7: 1.4. Familial occurrence was found in 18 of 281 families of the propositi (6.4%).5. Other congenital anomalies and/or disorders were found to be assoc iated in 41 cases (12.3%). Congenital heart diseases were most frequently seen in 14 cases (4.2%).6. Surgical treatments were performed in 215 cases,171 of 227 primary ca ses (75.3%) and 44of 105 secondary cases (41.9%). Surgical procedures were cheiloplasty in 127 cases, palatoplasty in 101 cases, secondary bone grafting for the alveolar cleft in 26 cases, and rhinoplasty in 22cases.
