Secondary repair of cleft lip deformity

A considerable number of procedures have been described for secondary improvements of the lip. They involve the scars, the Cupid's bow, the philtrum, the alar base, the vestibulum and the columella. In fact, these procedures may give a good aesthetic result in a static position, but the truly successful results occur with normal movements. A normal motion of the lip is impossible without a proper dissection and reorientation of the muscles. Satisfactory lip motion cannot be realized with a defective alveolus or piriform aperture that retracts the alar base. Consequently, a good lip or nasal base cannot be achieved without bony restoration of the alveolus and piriform aperture. A transversely short lip never has normal mobility, and it must be widened by an Abbé flap. A tight, retruded lip on a retruded maxilla cannot be improved by a prosthetic vestibular plate because a greater tension will restrict movements. The lip must be advanced with the maxilla, then widened if necessary by an Abbé flap. A thick prolapsed lip never has normal movement; it must be raised by an infranasal excision. A cleft lip has nothing to gain from being displayed under a short nose, or, still worse, under a upturned nose. The nose must be kept long enough to cast a shadow on the lip. For the same reason, a bone graft is often necessary in bilateral clefts because the nose is short and retruded.
