Clinical Application of Foci Contralateral Facial Artery Myomucosal Flap for Tongue Defect Repair

Abstract

Summary:. This study aims to investigate the clinical efficacy of foci contralateral facial artery myomucosal flap (FAMF) in repairing the defect of tongue after tumor resection. There were 10 cases who received the operation to repair tongue tissue defects caused by tumor resection from January 2010 to January 2016. FAMF flap size ranged from 2.5 × 3 cm to 5 × 5 cm. All flaps survived after surgery, and no local necrosis occurred. For the donor and receptor sites of 10 cases, 8 cases got wounds healed at stage I, wound dehiscence of donor site occurred in 2 cases, and the dehisced wounds were healed after local cleaning. All 10 patients were followed up for 13 months to 5 years, with an average of 2 years and 4 months. No obvious deformity appeared on face after surgery, and there was no mouth floor leakage. After surgery, 3 cases had clinical manifestations of facial nerve marginal mandibular branch injury and returned to normal in 3 months. All patients had a limitation for mouth opening after surgery, 9 cases returned to normal after 1 year, and 1 case still had a mild limitation for mouth opening. There was no impact on patients’ eating, swallowing, language, or other functions. The foci contralateral FAMF surgery is simple and brings ideal plastic effect, high survival rate of flap, less donor site lesion, simple postoperative care, no breaking after surgery, and no impact on radical cure of tumor, which is suitable for repairing defect of tongue.
