Abstract
Data from our division (Division for Oral-Facial Disorders, Osaka University Faculty of Dentistry) have been used to make a clinicostatistical analysis of cleft palate. From 1995 to 2000,429 cases were registered in our division. The date of birth, cleft type, address, and referred department were studied in these cases.
The results were as follows:
1. The mean number of cases registered in our division was 85.8 per year.
2. The resident distribution of the patients was 92.1% from the Kinki area; in particular,70.8% were from around our hospital address.
3. Cleft morphology was classified into five categories: BCLP in 83 cases (19.3% ), UCLP in 162 cases (37.8% ), ICP in 139 cases (32.4% ), SMCP in 36 cases (8.4% ), and BU in 9 cases (2.1% ).
4. The laterality in CLP cases was unilateral in 66.1%, and bilateral in 33.9%. The laterality in UCLP cases was the left side in 64.2%, and the right side in 35.8%.
5. Referral from inside the hospital is found in 72.9% of all cases.
