ObjectiveTo evaluate the effectiveness of different flaps for repair of severe palm scar contracture deformity. MethodsBetween February 2013 and March 2015, thirteen cases of severe palm scar contracture deformity were included in the retrospective review. There were 10 males and 3 females, aged from 14 to 54 years (mean, 39 years). The causes included burn in 9 cases, hot-crush injury in 2 cases, chemical burn in 1 case, and electric burn in 1 case. The disease duration was 6 months to 6 years (mean, 2.3 years). After excising scar, releasing contracture and interrupting adherent muscle and tendon, the soft tissues and skin defects ranged from 6.0 cm×4.5 cm to 17.0 cm×7.5 cm. The radial artery retrograde island flap was used in 2 cases, the pedicled abdominal flaps in 4 cases, the thoracodorsal artery perforator flap in 2 cases, the anterolateral thigh flap in 1 case, and the scapular free flap in 4 cases. The size of flap ranged from 6.0 cm×4.5 cm to 17.0 cm×7.5 cm. ResultsAll flaps survived well. Venous thrombosis of the pedicled abdominal flaps occurred in 1 case, which was cured after dressing change, and healing by first intention was obtained in the others. The mean follow-up time was 8 months (range, 6-14 months). Eight cases underwent operation for 1-3 times to make the flap thinner. At last follow-up, the flaps had good color, and the results of appearance and function were satisfactory. ConclusionSevere palm scar contracture deformity can be effectively repaired by proper application of different flaps.
ObjectiveTo investigate the clinical anatomy and application of free profunda femoral artery pedicled chimeric myocutaneous perforator flap in the defect reconstruction after radical resection of tongue carcinoma. MethodsBetween April 2011 and January 2016, 44 cases of tongue carcinoma underwent radical resection, and tongue defects were reconstructed by free profunda femoral artery pedicled chimeric myocutaneous perforator flaps at the same stage. There were 40 males and 4 females, with a mean age of 46.3 years (range, 32-71 years). The pathologic type was squamous cell carcinoma, which involved the lingual margin in 24 cases, the ventral tongue in 17 cases, and the mouth floor in 3 cases. According to Union for International Cancer Control (UICC) TNM staging, 16 cases were rated as T4N0M0, 11 cases as T4N1M0, 9 cases as T3N1M0, and 8 cases as T3N2M0. The course of disease ranged from 1 to 22 months (mean, 8.6 months). The size of perforator flap ranged from 8.5 cm×4.0 cm to 12.0 cm×6.5 cm, and the size of muscle flap ranged from 4.0 cm×3.0 cm to 7.5 cm×5.0 cm. The adductor magnus myocutaneous flap with a pedicle of (8.3±0.5) cm was used in 11 cases, and the gracilis muscle myocutaneous flap with a pedicle of (8.1±0.8) cm was used in 33 cases. The donor sites were sutured directly. ResultsAll 44 perforator flaps survived uneventfully, and the donor site healed well. The patients were followed up for 12 to 40 months (mean, 23.8 months). The reconstructed tongue had good appearance and function in swallowing and language. No local recurrence was found. Only linear scar was left at the donor sites. ConclusionThe free profunda femoral artery pedicled chimeric myocutaneous perforator flap can be harvested in various forms, and is an ideal choice to reconstruct defect after radical resection of tongue carcinoma.
Since 1982. nineteen cases of defect of mouth floorhave been treated by free skin flap and myocutaneous flapgrafts. All of cases were sucecssful with good appearence andfunctions. The repairing method of defect of mouth floorwere disscused and verious free skin flaps graft in repairingdefect of mouth floor were evaluated.
Objective To evaluate the effectiveness of free flaps in repairing hot-crush injury in the dorsum of hand. Methods Between February 2003 and February 2012, 32 cases of hot-crush injuries in the dorsum of hand were repaired. There were 25 males and 7 females with an average age of 24 years (range, 16-45 years). The injury causes included machine crush injury in 9 cases, machine-press injury in 13 cases, and iron panel injury in 10 cases. The time from injury to admission ranged from 90 minutes to 8 hours (mean, 3 hours). The wound size ranged from 6 cm × 5 cm to 17 cm × 11 cm. Associated injuries included the extensor tendon necrosis in 12 cases, and the second metacarpal bone necrosis in 1 case. One-stage emergency debridement was performed in all cases; two-stage flap repair was given at 7-21 days when the necrotic area became determined. The dorsalis pedis flaps were used in 9 cases, the anterolateral thigh flaps in 9 cases, the latissimus dorsi flaps in 3 cases, the thoraco-umbilical flaps in 3 cases, and the lower abdominal flaps in 8 cases. The flap size ranged from 7 cm × 5 cm to 18 cm × 16 cm. The donor site was repaired by skin graft or sutured directly. Results All the flaps survived. Primary healing of wound was obtained in 25 cases and delayed healing in 7 cases. Skin graft at donor site survived, with healing of incision by first intention. Twenty-three cases were followed up 6-25 months (mean, 13 months). Thinning was carried out in 8 bulky flaps; the other flaps had good appearance and texture. At last follow-up, the range of motion (ROM) of the metacarpophalangeal joint ranged from 40 to 80° (mean, 58°); ROM of the proximal interphalangeal joint ranged from 35 to 70° (mean, 52°); and ROM of the distal interphalangeal joint ranged from 5 to 25° (mean, 12°). The sensation recovery of the flaps were more than S2. No scar formed at donor site. Conclusion Suitable free flap should be selected to repair hot-crush injury in the dorsum of hand according to size of wound, which will achieve satisfactory results.
ObjectiveTo discuss the effectiveness of free anterolateral thigh flap pedicled with medial sural vessels for treatment of leg skin and soft tissue defects. MethodsBetween July 2008 and January 2014, 32 cases of serious skin and soft tissue defects in the leg were repaired by using free anterolateral thigh flap pedicled with medial sural artery and vein. Of them, there were 22 males and 10 females, aged 23 to 50 years (mean, 36.5 years). Defects were caused by traffic accidents injury in 9 cases, crash injury of heavy object in 15 cases, and machine twist injury in 8 cases. The left side was involved in 10 cases and the right side in 22 cases. The mean interval of injury and admission was 2.5 hours (range, 1-4 hours). The location was the upper, middle, and lower one third of the anterior tibia in 15 cases, 10 cases, and 7 cases respectively. The area of defect ranged from 10 cm×5 cm to 23 cm×9 cm. After debridement and vaccum sealing drainage treatment, the anterolateral thigh flap ranging from 12 cm×7 cm to 25 cm×11 cm pedicled with the medial sural vessels was used to repair the wound. The donor site was sutured directly or repaired with the skingrafts. ResultsAll flaps and skingrafts survived after operation, and primary healing of wound was obtained. After 6-23 months (mean, 14.5 months) follow-up, all flaps were characterized by soft texture, good color, and satisfactory appearance. The sensation of the flaps were recovered to S2~S3+ according to the Britain's Medical Research Council criteria at 6 months after operation. No obvious scar contracture was observed at donor site. ConclusionThe medial sural artery has the advantages of constant anatomical position, large diameter, rich blood flow, and a long artery pedicle, so the medial sural vessels is an ideal choice as recipient vessels for the reconstruction of leg skin and soft tissue defect.
ObjectiveTo investigate the effectiveness of different free flaps in the repair of large defects after resection of scalp malignant tumors. MethodBetween March 2012 and January 2015, 18 patients with large defect after resection of scalp malignant tumors were treated with different free flaps. There were 13 males and 5 females with an average age of 49 years (range, 18-72 years). There were 17 cases of squamous carcinoma and 1 case of dermato-fibril sarcoma protuberans. The defect size ranged from 15 cm×12 cm to 22 cm×17 cm after resection of tumors. Defects were repaired with anterolateral thigh flap in 5 cases, latissimus dorsi myocutaneous flap in 6 cases, thoracodorsal artery perforator flap in 3 cases, and latissimusdorsi muscle flap plus intermediate split thickness skin graft in 4 cases. The flap size was 17 cm×14 cm to 24 cm×19 cm. The donor sites of the skin flap were covered with skin graft, while the donor sites of the muscle flap were directly sutured. ResultsOf 14 skin flaps, the other 13 flaps survived except 1 flap necrosis; all muscle flaps survived. The patients were followed up 5-33 months (mean, 20 months). Three patients died because of intracranial metastasis at 5, 7, and 13 months after operation, respectively. Two patients had local recurrence and underwent secondary operation. The results of both appearance and function were satisfactory; secondary operation of thinning the flaps was performed in 4 cases of bulky flaps. The flaps had good wear resistance, without ulceration during follow-up. No obvious impairment was observed after harvesting latissimus dorsi myocutaneous flap. ConclusionsLarge scalp defects after malignant tumor resection can be effectively repaired by proper application of different free flaps.
