Abstract:
Oblique facial clefts constitute approximately 0.20% of all facial malformation cases in Japan and approximately 0.22% in other countries. In the present study, the proportion in our institute was approximately 0.21%, which is almost equal to that reported by WILSON et al. The ratio of male and female patients did not differ significantly from that in other countries.
