Closure of fistula of the hard palate with two layers of mucoperiosteum
Abstract Objective Oronasal fistula represents a functional problem, as it may result in nasal regurgitation of food and fluids and it also leads to hypernasal speech. Many methods have been proposed for its closure with a high recurrence rate. The aim of this study was to assess the efficacy of closure of hard palate fistula by two layers of mucoperiosteal flaps. Methods Eighteen patients with fistula of the hard palate were included. The fistula was repaired by two layers of mucoperiosteal flaps; the first layer was created from the mucoperiosteum surrounding the fistula as bilateral hinge flaps and the second layer was formed of a rotational flap based on the greater palatine artery. Pre- and postoperative clinical assessment was performed. Results The etiology of fistulas was previous cleft palate repair in 13 patients, previous nasal septal surgery in 3 patients, and untreated sharp accidental trauma to the palate in 2 patients. All patients presented with nasal regurgitation and hypernasal speech. Complete closure of all fistulas was achieved at first attempt, with no recurrence through the follow up period. Conclusions Closure of oronasal fistula by two layers of mucoperiosteal flaps is an effective method and it has neither complications nor recurrence.
