Appendix I -
Cleft Lip Nasal Deformity
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
BILATERAL CLEFT

Medial crura short bilaterally
Lateral crura short bilaterally, caudally displaced Tip-defining points poorly defined and widely separated Columella:
Short, with a wide base
