Prelaminated Fascia Lata Free Flap for Oronasal Fistula Reconstruction.

Oronasal fistulae are frequently symptomatic due to rhinolalia and regurgitation of solid food and liquids through the palate. When asymptomatic, fistulae can be managed with conservative therapies. Local flaps are useful to close small fistulae but cannot be used in bigger ones and cases with bad-quality surrounding tissues. Ideally, a thin double-layer mucosal tissue is required, but there are no suitable donor sites for this tissue in the human body. We report a palate fistula reconstruction with prelaminated fascia lata free flap.
