Anatomical Variations in Clefts of the Lip with or without Cleft Palate

Table 2

Cleft lip—severity of cleft according to gender and laterality.

These figures for CL reveal a reasonable level of consistency across regions in proportions of complete to incomplete clefts with incomplete clefts being consistently more prevalent than complete ones. Also complete clefts of the lip seem to occur more frequently in females. Bilateral clefts were excluded from this analysis.
