The facial muscles are divided into three muscular rings. The first ring is formed by the nasolabial group, the second by the bilabial group, and the third by the labiomental ring. All three rings are disrupted when cleft of the lip with/without palate occurs. The resultant disturbance in muscular function within these anatomic muscular units secondarily produces distortions in the growth of surrounding skeletal and cartilaginous structures that theoretically escalate over time. Accurate reconstruction of these different muscular layers of the lip is important for normal lip function, and also to stop further distortion of underlying hard tissue structures.

It is generally assumed that the major phenotypes of unilateral cleft lip (UCL) represent its extent of severity. There are a few studies on this, but objectivity has been lacking. It was the aim of this study to assess the effect of different phenotypes of the unilateral cleft lip on the outcome of surgical repair this study was a case series of the effect of phenotypes of cleft on the outcome of repair of unilateral cleft lip. Fifteen subjects each were in three unilateral cleft lip phenotype groups. Surgical outcome was assessed quantitatively with anthropometric measurements recorded from a full-frontal face photograph of subjects. The analysis was done using Student's t-test and one-way ANOVA at P = 0.05.

The mean values of the preoperative horizontal and vertical lip height and nasal width on the cleft side in the cleft lip (CL) group were closest to those of the noncleft side and control. The postoperative mean values of the horizontal and vertical lip height and nasal width on the cleft side in the cleft lip group were closest to those of the noncleft side and control, while those of the cleft lip, alveolus, and palate group were farthest from those of the noncleft side and the control. The different phenotypes of the unilateral cleft lip have different degrees of tissue distortion and deficiencies. cleft lip group had its measurements closest to that of the noncleft sides and control, suggesting that it has the least distortion. The comparison between the three groups did not reveal any difference, suggesting that the skill of the surgeon and the selection of a well-proven technique are more important factors in the outcome of repair of unilateral cleft lip.
