Oronasal Fistula Closure using Two-Flap Palatoplasty with Intravelar Veloplasty

The purpose of cleft palate repair surgery is to recover normal mastication, swallowing and phonation function. In cleft palate patients, soft palate muscles are abnormally arranged and attached posteriorly to the hard palate. Intravelar veloplasty for reconstruction of muscle sling is required for these patients for separation of oral cavity from nasal cavity and the sphincter function of the pharynx. Closure of large oronasal fistula is very challenging for Oral & Maxillofacial surgeons, and the rate of recurrence after surgery has been reported to be 11-25%. Various methods for closure of oronasal fistula have been reported. The most important technical principle is to perform tension-free sutures of the mucoperiosteal flaps. We report 2 cases oronasal fistula closure using of two-flap palatoplasty with intravelar veloplasty with discussion on the surgical keys of this procedure.
