  • Application of free-style perforator flap for soft tissue defect of knee

    ObjectiveTo investigate the effectiveness of free-style perforator flap in repairing the soft tissue defect of knee.MethodsBetween December 2011 and October 2017, 13 patients with the soft tissue defects of knees were repaired with the free-style perforator flaps. There were 9 males and 4 females, with an average age of 40 years (range, 14-65 years). The injuries were caused by traffic accident in 7 cases, crushing in 4 cases, and falling from height in 2 cases. The soft tissue defects in 9 cases formed after 2 weeks-2 months (mean, 1 month) of lower extremity fractures fixation. The other 4 cases were urgently admitted to the hospital after injury, and the time from injury to admission was 0.5-18.0 hours (mean, 8 hours). The size of soft tissue defect ranged from 3 cm×2 cm to 12 cm×8 cm after debridement. Nine propeller flaps, 6 rotating flaps, and 2 V-Y advanced flaps were used; and 9 cases were repaired by single flap and 4 cases were repaired by combined flaps. The size of flap ranged from 7.5 cm×2.5 cm to 20.0 cm×6.0 cm. The donor sites were sutured directly.ResultsThe flaps survived smoothly and incisions healed by first intention in 12 cases. The congestion occurred in 1 case, which obtained delayed healing after symptomatic treatment. All incisions at donor sites healed by first intention. All patients were followed up 3-24 months with an average of 6 months. The shape and motions of knee were satisfactory.ConclusionThe free-style perforator flap can maximize the utilization of the donor area around the knee wound, with reliable blood supply, small trauma, and easy operation. It is an ideal flap for the soft tissue defect of knee.

  • APPLICATION OF NARROW HYPODERMAL PEDICLED RETROAURICULAR FLAP IN REPAIRINGPREAURICULAR SOFT TISSUE DEFECT

    Objective To investigate the technique and effectiveness of using narrow hypodermal pedicled retroauricular flap for repairing preauricular soft tissue defect. Methods Between June 2008 and July 2011, 11 cases of preauricular soft tissue defect were treated, which were caused by resection of preauricular tumors, including 5 cases of pigmented nevus, 2 cases of basal cell carcinoma, 2 cases of mixed hemangioma, and 2 cases of skin papilloma. There were 7 males and 4 females, aged from 26 to 75 years (mean, 50 years). The disease duration was 3-50 years (mean, 35 years). The size ofthe soft tissue defect ranged from 1.5 cm × 1.0 cm to 3.5 cm × 3.0 cm. The narrow hypodermal pedicled retroauricular flap was designed with its pedicle along the pathway of the superficial temporal artery and posterior auricular artery through tunnel to repair the defects. The size of the flaps ranged from 1.8 cm × 1.3 cm to 3.8 cm × 3.3 cm with the pedicle of 2-5 cm in length and 0.4-0.7 cm in width. The donor site was sutured directly or repaired with local flap. Results All flaps survived and incisions healed primarily after operation. Eight cases were followed up 6 months to 1 year. The flaps had good texture, flexibil ity, and color, and the auricle appearance was satisfactory. No recurrence of tumor was found. Conclusion The narrow hypodermal pedicled retroauricular flap has long and narrow pedicle, big transferring angle, large repairing area, no major blood vessel, and easy operation, so it is a simple and ideal technique for repairing preauricular soft tissue defect.
