ObjectiveTo summary the application and effectiveness of the posterior radial collateral artery (PRCA) compound flap in reconstruction of soft tissue defect after tongue cancer excision. MethodsBetween August 2011 and October 2011, 5 patients with squamous cell carcinoma underwent tongue defects reconstruction with compound flap with extended lateral arm free flap (ELAFF) and triceps muscle flap (TMF) after ablation in one-stage. All patients were male with an average age of 59 years (range, 43-71 years). The disease duration was 25-60 days (mean, 42 days). After extended resection, 3 cases had 1/3 tongue and mouth floor defect, and 2 cases had 1/2 tongue and mouth floor defect. The size of ELAFF ranged from 7 cm × 5 cm to 9 cm × 5 cm, and the size of TMF ranged from 3 cm × 3 cm to 4 cm × 4 cm. The donor sites were directly sutured. ResultsAll compound flaps survived. The wounds at donor sites and recipient sites healed primarily. The patients were followed up 6 months. After operation, the tongue had good appearance and motion; the patients had clear voice and no dysphagia. No recurrence was observed during follow-up. Local numbness appeared at the donor sites, but the function of the elbows was normal. ConclusionThe application of the compound flap of ELAFF and TMF based on PRCA perforator is a better option to reconstruct tongue defects for its reliable blood supply, appropriate thickness, easy operative procedures, and less complication.
Objective To explore the feasibility and effectiveness of radial collateral artery polyfoliate perforator flap in repair of resurfacing soft tissue defect of hand. Methods Between September 2017 and September 2018, the radial collateral artery polyfoliate perforator flaps were transplanted to repair 5 cases of two adjacent wounds of hand and wide or irregular wounds. All patients were male, aged from 27 to 52 years, with an average of 42.5 years. The time from injury to admission was 4 hours to 3 weeks, with an average of 7.3 days. Causes of injury included traffic accident in 2 cases, crushing injury in 2 cases, and paint injection injury in 1 case. The wounds were located at the dorsum of hand in 3 cases, the dorsum of finger in 1 case, and the thumb and thumb web in 1 case. The area of wound ranged from 8 cm×6 cm to 10 cm×8 cm. The area of skin flap ranged from 6.0 cm×3.0 cm to 11.0 cm×4.5 cm, all of which carried the posterior cutaneous nerve of the arm, and the donor site was closed directly. Results All flaps survived and healed by first intention. All patients were followed up 3-11 months (mean, 6.5 months). The patients were satisfied with the appearance of hands. The flaps were not bulky, and the color and texture were similar to the hand. There was only linear scar in the donor site, no radial nerve injury occurred, and elbow joint function was not affected. One patient underwent finger-splitting and skin flap thinning at 6 months after operation. Conclusion The radial collateral artery polyfoliate perforator flap is a good method for repairing two adjacent wounds and wide or irregular wounds of hand.
