Objective To introduce the free multiple flaps of lowerextremity based on the anterior tibital vascular pedicle for primary repair of the complex burned hand deformities.Methods From September 2000 to February 2003, the lateral leg flap, dosalis pedis flap and trimmed first toe based on the anterior tibial vascular pedicle were utilized to reconstruct the thumb and repair the first web, thenar, wrist or palmar scar contracture simultaneously in 6 patients. The flap size of lateral leg and dosalis pedis ranged from 4 cm×10 cm to 7 cm×10 cm and from 5 cm×10 cm to 9 cm×12 cm, respectively.Resutls Six cases were treated and followed up for 6 weeks to 1 year. The transplanted flaps survived with satisfactory recovery in function and appearance of theburned hand. The function of donor lower extremity was not damaged. Conclusion The procedure of the free multiple flaps of lower extremity based on the anterior tibial vascular pedicle is reliable and effective for primaryrepair of burned hand.
ObjectiveTo investigate the effectiveness of dorsalis pedis flap series-parallel big toe nail composite tissue flap in the repairment of hand skin of degloving injury with tumb defect. MethodsBetween March 2009 and June 2013, 8 cases of hand degloving injury with thumb defect caused by machine twisting were treated. There were 7 males and 1 female with the mean age of 36 years (range, 26-48 years). Injury located at the left hand in 3 cases and at the right hand in 5 cases. The time from injury to hospitalization was 1.5-4.0 hours (mean, 2.5 hours). The defect area was 8 cm×6 cm to 15 cm×11 cm. The thumb defect was rated as degree I in 5 cases and as degree II in 3 cases. The contralateral dorsal skin flap (9 cm×7 cm to 10 cm×8 cm) combined with ipsilateral big toe nail composite tissue flap (2.5 cm×1.8 cm to 3.0 cm×2.0 cm) was used, including 3 parallel anastomosis flaps and 5 series anastomosis flaps. The donor site of the dorsal flap was repaired with thick skin grafts, the stumps wound was covered with tongue flap at the shank side of big toe. ResultsVascular crisis occurred in 1 big toe nail composite tissue flap, margin necrosis occurred in 2 dorsalis pedis flap;the other flaps survived, and primary healing of wound was obtained. The grafted skin at dorsal donor site all survived, skin of hallux toe stump had no necrosis. Eight cases were followed up 4-20 months (mean, 15.5 months). All flaps had soft texture and satisfactory appearance;the cutaneous sensory recovery time was 4-7 months (mean, 5 months). At 4 months after operation, the two-point discrimination of the thumb pulp was 8-10 mm (mean, 9 mm), and the two-point discrimination of dorsal skin flap was 7-9 mm (mean, 8.5 mm). According to Society of Hand Surgery standard for the evaluation of upper part of the function, the results were excellent in 4 cases, good in 3 cases, and fair in 1 case. The donor foot had normal function. ConclusionDorsalis pedis flap series-parallel big toe nail composite tissue flap is an ideal way to repair hand skin defect, and reconstructs the thumb, which has many advantages, including simple surgical procedure, no limitation to recipient site, soft texture, satisfactory appearance and function of reconstructing thumb, and small donor foot loss.
Objective To evaluate the advantages and disadvantages of vascularized free peroneal composite flaps for reconstruction of oral and maxillofacial defects. Methods From November 1999 to December 2002, 28 cases of oral maxillofacial defects were reconstructed with vascularized free peroneal composite flaps, with fibulacutaneous flap in 21 cases and with fibulamyocutaneous flap in 7 cases. Three cases received insertion of dental implants into the fibula flap. The flap size was 3.0 cm×5.5 cm to 8.0 cm ×12.0 cm; the fibula length was 5.5 cm to 16.0 cm. Results Of the 28 flaps reconstructed, 24 survived,3 necrosed partially and 1 necrosed completely. All the 5 implants survived andachieved good bone integration in 3 cases. Twenty-six cases were followed up 1-36 months with an average of 18.5 months, the facial appearance and the vocal function were satisfactory in 23 cases. Conclusion Vascularized peroneal flap has many advantages and is one of the optimal flaps for reconstruction of oral maxillofacial defects.
目的 总结改良耳廓复合组织瓣修复鼻翼巨大缺损的方法和经验。 方法 2005年9月－2010年9月共收治11例巨大鼻翼缺损患者，术前根据鼻翼缺损的形状、大小和位置设计切取耳廓复合组织瓣的形状、大小和部位，供瓣区分层缝合。游离组织瓣分层嵌入间断缝合于受区。术后随访1～3年。 结果 11例皮瓣均完全存活，颜色与周围皮肤无明显差异，表面无黑痂，无表皮分离，随访见周围缝合切口轻微瘢痕形成，复合组织瓣无明显挛缩，与健侧对比形态自然、大小差异不明显，供瓣区耳廓形态良好。 结论 通过细致合理的设计及复合组织瓣嵌入后缝合，配合术后促进局部血液循环治疗，改良耳廓复合组织瓣植入法可有效修复巨大鼻翼缺损。
ObjectiveTo assess the effectiveness of the sural fasciomyocutaneous perforator flap in repair of soft tissue defect in weight-bearing area of the foot. MethodsBetween January 2007 and September 2010, 19 patients with soft tissue defects in the weight-bearing area of the foot were treated with sural fasciomyocutaneous perforator flaps. The etiology was traffic accident in 16 patients and crush injury in 3 patients. The interval of injury and admission was 2 hours to 14 days. The size of defect ranged from 8 cm×6 cm to 26 cm×16 cm; the size of flap ranged from 7 cm×7 cm to 25 cm×12 cm. The donor sites were repaired by free skin graft. The flap survival was observed after operation, and the pain score and sensory recovery at the reci pient site were used to assess the effectiveness. ResultsThe flaps survived with satisfactory aesthetic and functional results in 18 cases. Partial flap necrosis was noted and second healing was achieved after spl it thickness skin grafting in 1 case. One case of delayed ulceration was also noted after 5 weeks, ulceration was successfully cured after wound care and avoidance of weightbearing for 2 weeks. All patients were followed up 9-25 months (mean, 14.1 months). The flaps had good appearance, without bulky pedicle. Superficial sensation and deep sensation were restored in 17 cases (89.4%) and 18 cases (94.7%) respectively at last follow-up. ConclusionSural fasciomyocutaneous perforator flap is a rel iable modality in heel reconstruction, having the advantages of low ulceration rate, good wear resistance, and good sensation recovery.
