RESUMO
Objective@#To evaluate the feasibility and outcomes of the reconstruction of large anterior palatal fistulae by anteriorly based dorsal tongue flaps to provide a rational reference of anteriorly based dorsal tongue flaps for clinicians.@*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, whether 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 patients underwent successful reconstruction of palatal defects by anteriorly based tongue flaps, and no case of spontaneous detachment of the tongue flap occurred. Patients with palatal fistulae were followed up for 16-28 months, and no recurrence 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 anterior tongue is a safe and reliable method for repairing large anterior palatal fistula.
