Closure of fistula of the hard palate with two layers of mucoperiosteum

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.
