Experience with Surgical Management of Velopharyngeal Incompetence

Accurate mapping of the defect of velopharyngeal closure in patients with velopharyngeal incompetence is paramount to the planning of an operative procedure that will have a successful outcome. Nasoendoscopy and videonasoendoscopy are valuable tools for examination of the abnormal pattern of velopharyngeal movement in patients with velopharyngeal incompetence. On the basis of the knowledge of the observed defect in velopharyngeal closure for the particular patient, a pharyngeal flap operation is planned. The flap width, level of placement of the flap base, and control of the lateral port size vary to suit each individual velopharyngeal closure defect. Postoperative speech results in 86 patients are reported.
