UNILATERAL CLEFT (Fig. 3)

Nasal tip:

Medial crus of LLC shorter on cleft side

Lateral crus of LLC longer on cleft side (total length of cleft and noncleft side LLC are the same)

Tip-defining point on cleft side is flat and laterally displaced

Columella:

Short on cleft side

Columellar base directed to noncleft side (unopposed orbicularis muscle)

Nostril:

Horizontal orientation on cleft side

Alar base:

Laterally, inferiorly, and posteriorly displaced on cleft side

Nasal floor:

Usually absent

Septum:

Caudal deflection to noncleft side

Posterior deflection to cleft side
