BACKGROUND: The palatal fistula is an important surgical challenge within the longitudinal follow-up of patients with repaired cleft palate as the success rate of palatal fistula reconstruction by adopting several surgical techniques is variable and often unsatisfactory. The purpose of this retrospective study was to report the clinical outcomes of an algorithm for the surgical management of palatal fistulae in patients with repaired cleft palate. METHODS: Consecutive patients (n = 101) with repaired cleft palate and palatal fistula-related symptoms who were treated according to a specific algorithm between 2009 and 2017 were included. Based on the anatomical location (Pittsburgh fistula types II-V), amount of scarring (minimal or severe scarred palate), and diameter of the fistula (≤5 mm or >5 mm), 1 of 3 approaches (local flaps [62.4%], buccinator myomucosal flaps [20.8%], or tongue flaps [16.8%]) was performed. For clinical outcome assessment, symptomatic and anatomical parameters (fistula-reported symptoms and residual fistula, respectively) were combined as follows: complete fistula closure with no symptoms; asymptomatic narrow fistula remained; or failure to repair the fistula ("good," "fair," or "poor" outcomes, respectively). Surgical-related complication data were also collected. RESULTS: Most patients (91.1%) presented "good" clinical outcomes, ranging from 86.2% to 100% (86.2%, 100%, and 100% for local flaps, buccinator flaps, and tongue flaps, respectively). All (8.9%) "fair" and "poor" outcomes were observed in fistulae reconstructed by local flaps. All "poor" (5%) outcomes were observed in borderline fistulae (4-5 mm). No surgical-related complications (dehiscence, infections, or necrosis) were observed, except for an episode of bleeding after the 1st stage of tongue flap-based reconstruction (1.0%). CONCLUSION: A high rate of fistula resolution was achieved using this algorithm for surgical management of palatal fistulae in patients with repaired cleft palate.
