Clinical effect of reconstruction of large anterior palatal fistulae by anteriorly based dorsal tongue flaps

Abstract

Objective To evaluate the feasibility and outcomes of the reconstruction of large anterior palatal fistu⁃ lae by anteriorly based dorsal tongue flaps to provide a rational reference of anteriorly based dorsal tongue flaps for clini⁃ cians. Methods Five patients with anterior hernia had a defect range of 1.0 cm × 1.0 cm to 1.5 cm × 2.0 cm, and the anterior tongue was 1.3 cm × 3.5 cm to 2.0 cm × 3.5 cm. The defects were all repaired with anteriorly based dorsal tongue flaps. The clinical efficacy was evaluated after operation, including whether the mucosal flap was infected, wheth⁃ er there was any shedding before the pedicle, and whether there was any perforation after operation. Thereafter, patients who were satisfied with their chewing, swallowing, speech function and appearance were followed up. Results All pa⁃ tients underwent successful reconstruction of palatal defects by anteriorly based tongue flaps, and no case of spontane⁃ ous detachment of the tongue flap occurred. Patients with palatal fistulae were followed up for 16⁃28 months, and no re⁃ currence was encountered. The operation had no effect on the speech, agitation and swallowing function of the tongue, and patients were satisfied with the appearance. Conclusion The dorsal lingual mucosal flap pedicled with the anteri⁃ or tongue is a safe and reliable method for repairing large anterior palatal fistula.
