Abstract

Oronasal fistula is a complication which may be seen after palatoplasty. Prognostic results on 30 patients with surgical fistula closure in 1985-1994 at Kyushu University Dental Hospital were evaluated and classified into threegroups: “good”, “ acceptable ”, and “poor”. The results were analyzed in relation with characteristic factors of oronasal fistula and the results were as follows:<BR>1. The results was “ good ” in cases when rotation flap with bone grafting was employed fo r the closure of the fistula located in the anterior portion of the incisal bone.<BR>2. The result was “ good ” in cases with closure and bone grafting fo r the fistula located in the hard palate.<BR>3. The result was “ poor ” in cases with large oval fistula (not less than 5mm in diameter) located in the posterior portion of the incisal bone and with closure without bone grafting.
