Anterior-based Tongue Flap for repair of recurrent wide anterior palatal fistula, refreshment of the technique and the outcome.

Abstract

Purpose: The most complicated palatal operation is trial of closing large recurrent palatal fistula with previous attempts of closure, because of deficient local tissue which is fibrotic and relatively immobile, repeated surgery may jeopardize blood supply of the palatal tissue. The present study aims at evaluating the outcomes of using an anterior-based tongue flap in closure of recurrent wide palatal fistula.Methods: Fifteen children with wide anterior palatal fistula after previous failed trial for closure using local palatal tissues were included in the study. Patients were managed by anteriorly-based tongue flap to be separated after 2 weeks. Post-operative data were recorded regarding flap viability, recurrence, flap bulk, speech difficulty and tongue disability.Results: The mean age of included patients was 7.5 years. No intraoperative complications were recorded. Taste sensation and swallowing reflex were normal in all patients. Flap dehiscence and fistula recurrence was observed in one patient (6.66%). There was a statistically significant improvement in hypernasality post-operatively (P
