Abstract:Objective To investigate the clinical anatomy of free femoral artery perforator flap and its application in postoperative defect repair after resection of oral and buccal carcinoma.Methods From Dec 2015 to June 2019, 13 male patients with oral and buccal carcinoma underwent postoperative defect repair with free femoral artery perforator flap. All the patients aged from 37 to 61 years old, with an average of 48.5. The pathological type was squamous cell carcinoma. According to TNM staging, 5 cases were at T4N0M0, 2 at T4N1M0, 2 at T3N1M0, and 4 at T3N2M0. The disease course ranged from 3 to 16 months, with an average of 9.8. The specific forms of free femoral artery perforator flap included pure perforator flap in 7 cases and perforator chimera muscle ator flap in 6.Results The intraoperative planning flap size ranged from 6.5 cm×4.0 cm to 10.0 cm×6.5 cm with thickness of 2.5~3.5 cm. The vessel length of femoral artery perforator was (6.2±0.4) cm, and the donor sites were closed by gathering suture. The flaps survived in all the 13 cases with primary healing of the recipient and donor sites. Patients were followed up from 12 to 30 months, with an average of 21.3 months. The reconstructed oral cavity had satisfied appearance and good function without swelling or deviation. The donor sites remained good muscle function with slight scar.Conclusion Free femoral artery perforator flap can be used to repair local defect after radical resection of oral and buccal carcinoma.
