Fig. 3

Complete unilateral cleft lip and palate (CUCLP) before (A) and after (B) lip surgery. With the establishment of muscle continuity, the lesser segment moves medially, while the premaxillary portion of the larger segment moves medio-inferiorly, both acting to reduce the cleft width. Any of the following segmental relationships can result. B No contact between segments. The inferior turbinate on the cleft side makes premature contact with the bowed nasal septum. C The premaxillary portion of the larger segment overlaps the smaller segment. D The segments form a butt joint showing good approximation. (Both figures and notifications come from ref [23])
