【Abstract】 Objective To investigate the method and effectiveness of expanded delto-pectoral and abdominalperforator flaps in repairing large defects of the face and upper limb after scar excision. Methods Between August 2000 and February 2011, 25 patients with large scars on face and upper l imb were treated. There were 14 males and 11 females with an average ageof 27 years (range, 7-36 years). Scars causes were burn and scald in 25 cases with a disease duration of 6 months to 7 years (mean, 4.5 years). The hypertrophic scars located at face in 15 cases, and at upper limb and hand in 10 cases. The soft tissue expanders (300-500 mL in volume) were implanted in the delto-pectoral zone and abdominal region in one-stage operation. In two-stage operation, after scars were resected, defects (9 cm × 7 cm to 17 cm × 8 cm) were repaired with the delto-pectoralperforator flaps (17 cm × 7 cm to 20 cm × 8 cm) in 15 facial scar cases and with the deep inferior epigastric artery perforator flaps (10 cm × 9 cm to 25 cm × 14 cm) in 10 upper limb and hand scar cases. The donor sites were sutured directly. Results Partial necrosis of the flaps occurred in 2 cases after operation, then the flap survived after expectant treatment. The other flaps and skin grafts survived successfully, and the incisions healed by first intention. Ten patients were followed up 6 months to 4 years. Theappearance, texture, and color of the flaps were similar to those at the donor site. Conclusion It is an effective method to use the delto-pectoral perforator flap and the deep inferior epigastric artery perforator flap for repairing soft tissue defects of the face and upper limb after scar excision.
Objective To evaluate a new reconstruction method for grades Ⅴ and Ⅵ defect with flap by skin soft tissue expansion technique. Methods From May 1998to September 2003, 8 cases of serious thumb defect were treated, including 6 males and 2 females, aging 18-27 years. The defect was caused by crush injury ofmachine in 6 cases and hot crush injury in 2 cases( 5 cases of grade Ⅴ and 3 cases of grade Ⅵ). The expander was placed under the tenor skin and softtissue.And then normal saline was infused to expand the skin and soft tissue graduallytill it was available for thumb reconstruction. Iliac autograft was fixed to residual thumb stump and covered with flap produce by expanded skin and soft-tissue.Postoperative rehabilitation was carried out. Results Allreconstructed thumbs were alive. After3-24 months follow-up, all reconstructed thumbs were with good sensation, appearance and durable. Twopoint discrimination was less than 5 mm. The functions of opposition, extend, abduction and endoduction were better in grade Ⅴ thumb defect than in grade Ⅵ thumb defect. Bone union was achieved within 3 to 4 months. Conclusion It is a convenient-to-operate and reliablemethod for thumb reconstruction. It is an alternative new reconstruction methodfor grades Ⅴ and Ⅵ thumb defect.
OBJECTIVE To introduce the clinical application of the expanded graft from scalp in the repair of cicatricial baldness in children. METHODS 45 cases with baldness following burn from 1988 to 1998 were reported. All of these patients (age ranged from 5-11 years) were treated by soft tissue expander. RESULTS 5 cases were followed up for 1-2 years, the clinical results showed that the result from the graft of scalp expansion was satisfactory, and the long-term follow-up revealed that the hair in expended area and that in normal area was almost the same except the orientation of hair distribution had some difference. CONCLUSION The head scalp expansion might be the first choice in the repair of cicatricial baldness following burn.
Abstract In order to investigate the pattern of the changes of blood supply of the vascular superthin skin flap during expansion, in 17 patients, under the subdermal vessel networks layer of the periauriclar area, an expander was placed, and the skin was preliminarily expanded. The changes of blood supply were found regular: When the injected fluid volume was excessive, the skin became pale or cyanotic, the skin showed congestive telangiectasis. If great care was given during the procedure, the expanded skin could pass safely through the stage of poor blood circulation. The expanded superthin skin flap were applied in auriculoplasty in 17 patients. The results included 3 failures, and 14 satisfactory.
