title: Repair of a submucous cleft palate by W-pushback and levator repositioning without incision to the nasal mucosa.
abstract: The author created an innovative method of W-pushback and levator repositioning without having to make an incision to the nasal mucosa for submucous cleft palate repair.The W-shaped mucoperiosteal flap is outlined where the 2 peaks of W are the alveolar processes of both canine teeth and the midpoint of W is the anterior limit of the cleft notch of the hard palate. A short incision, medial to and behind the maxillary tuberosity and curved forward onto the palate and extended forward just medial to the alveolar process, is joined by a second incision from the apex of the cleft to the region of the canine tooth. The W-shaped mucoperiosteal flap is raised until the midline notch of the hard palate is exposed. The nasal mucosa and abnormally inserted levator veli palatini muscle to the posterior border of the hard palate bone are detached. By leaving the nasal mucosa intact, the detached levator veli palatini muscle is approximated at the midline and so the zona pellucida is obliterated. The cleft uvulas are cut in half and closed. The approximated W-flap is joined to the small anterior flap by 1 or more sutures (the W-pushback).Three patients were operated on with this technique without serious complications.The author believes that this method can make the levator sling and increase the length of the soft palate without making an incision to the nasal mucosa.
