Reconstruction of Large Acquired Palatal Defects Using Facial-Submental Artery Island Flap

To evaluate the feasibility and clinical effect of facial-submental artery island flap (FSAIF) in the repair of palatal defects, and to provide reference for the clinical application of submental artery island flap.Nine patients with palatal defects, the range of nasal palatal perforation defects were 3 cm × 4cm to 3 cm × 6 cm (median 3 cm × 5.4 cm), were repaired by FSAIF, and the sizes of FSAIF were 4 cm × 9cm to 4 cm × 12 cm (median 4 cm × 10.4 cm,). Postoperative clinical efficacy was evaluated, including infection and necrosis of mucosal flap and postoperative palatal fistula perforation. Patients were followed up to evaluate their chewing, swallowing, speech function, and satisfaction of appearance.All patients were successfully repaired with FSAIF. Followed up 13∼35 months, there was no palatal fistula perforation in all patients. The speech, agitation, and swallowing function were not affected and the patients were satisfied with the appearance.FSAIF is a safe and reliable method for palatal defect repair.
