Three hundred Chinese patients with cleft lip and/or palate were reviewed in the Dentofacial Deformities Clinic of the Department of Dentistry at the United Christian Hospital between January 1990 and January 1992. A survey was taken of patients' age, sex, type of cleft, and cleft location. The findings from this survey are compared to an original sample of 2800 cleft patients surveyed earlier.
