In order to correct the dysfunction of head and neck with scar contracture, since 1980, sixty-two cases were undertaken the operation by using local skin flap to repair the soft tissue defect after scar resection. The skin flaps included pedicled delto-thoracic skin flap in 26 cases, cervico-thoracic skin flaps in 25 cases, cervico-shoulder flaps in 6 cases, pedicled vascularized extralong delto-thoracic skin flap in 4 cases and free parascapular flap in 1 case. Sixty cases had total survival of the flaps and 2 flaps had partial necrosis. After 1 to 10 years follow-up, the appearance and function of neck were excellent. It was suggested that grafting local skin flap was a good method to treat cicatricial deformity of neck especially using the skin flap with pedicle and vascular bundle.
In order to study the clinical efficacy of bilateral cervico-thoracic skin flap on repairing the contracture of the burn scar of the neck, 66 flaps were used in 33 patients from 1983 to 1995. The size of the flap ranged from 5 cm x 6 cm to 8.5 cm x 15 cm. The donor site was covered with split skin graft. The ratio between the length and the width of the flaps should not exceed 3:1. Fifty-nine flaps survived completely, but 7 had necrosis of small area which was healed without any influence on the function and appearance. The operative technique of the bilateral cervico-thoracic skin flaps were reported. The advantages of this type of skin flap and its applied anatomy and the postoperative care were discussed. In the repair of the cicatritial contracture deformity of the neck, it was important to define whether the skin defect was located in the submandibular, anterior cervical or anterior thoracic region, thus appropriate type of repair could then be given accordingly.

Based on the dye injection investigation, the territory of blood supply through the superficial temperal artery system was defined. Vascularized grafts, composed of temperal-parietal fascia, periosteum and outer-table of calvarial bone, can be transferred by microvascular anastomosis or transposed to repair full-thickness defects of skull bone was demonstrated. Six of such cases following electrical burn were successfully treated. The average size of skull bone defects was 50cm2. The largest one among them was 80cm2.
OBJECTIVE: To reduce amputation rate of severe electrical burn of wrist and to promote partial recovery of the injuried hand. METHODS: From 1987 to 1999, 44 cases, with 55 limbs of severe electrical burn were classified into 4 types, according to criteria of Dr Shen Zuyao, and were all treated by primary adequate decompression, timely debridement, reconstruction of blood circulation in cases complicated with blood vessel injury, and skin flap grafting from chest, abdomen or inguinal area, followed by treatment of anti-coaggluation and anti-infection. Once the wound healed, auto- or allo-transplantation or transferring of tendons were performed to repair tendon defect, and auto-nerve or fetal nerve transplantation performed for nerve defect. RESULTS: After the primary treatment of the 55 burned limbs, all limbs of type IV were amputated, and most of other 3 types survived. The function, including sensation and movement, of survived hands partially recovered. CONCLUSION: Primary reconstruction of blood circulation, cover of wound with skin flap, and timely repair of sensation and motor function are very crucial approach to reduce amputation rate and to promote the survived hand function of severe electrical burns of wrists.
OBJECTIVE: To evaluate the application of skin and soft tissue expansion in the treatment of deformity due to extensive severe burn injury and repair of severe deep electrical burned scalp and skull with fresh wound. METHODS: From 1988, 83 cases of application of skin and soft tissue expansion were reported. In those patients with deformity due to severe burn of large area and with whole nasal defect, soft tissue expander was used under the forehead skin graft and venter frontalis, followed by reconstruction of nose with the expanded vascularized skin flap and carved cartilago costalis as nasal frame. In patients of severe deep electrical burned scalp and skull with fresh wound, skin and soft tissue expansion were used to repair the wound simultaneously with scalp burn alopecia, anesthetics and antibiotics injected into the extracapsular space of the expander in case of pain and infection. RESULTS: All of the cases were successfully treated with little pain and minimized infection. CONCLUSION: Skin and soft tissue expansion in a safe and reliable measure in the treatment of deformity due to extensive severe burn injury and repair of severe deep electrical burned scalp and skull with fresh wound.
Objective To observe the clinical effect of the human tissue engineered activeskin (ActivSkin) with full thickness on the donor site of the split thickness skin graft. Methods Nine patients with 18 wounds of the donor sites, and every p atient had 2 wounds. The wounds of each patient were randomly assigned to the therapy group and the control group. Autocontrol observation was performed. Nine donor sites of the split thickness skin graft were repaired with ActivSkin in the therapy group. Nine donor sites of the split thickness skin graft were repaired with the vash oil gauze in the control group. The wound pain, the time to complete closure, and the ratio of the complete healing in the ActivSkin therapy gro up was measured and compared with those in the control group. The donor sites of the split thickness skin graft were assessed at 180 days of the follow-up visit . Results The wound pain was obviously reduced after the harvest ing of the skin grafts in the therapy group. The time to complete closure on the donor sites of the split thickness skin graft was significantly shorter in the ActivSkin therap y group than in the control group (9.67±2.92 d vs.16.56±2.96 d, Plt;0.05 ). Both the ratios of the complete healing in the ActivSkin therapy group and the control group were 100%（Pgt;0.05）. The subsequent results showed that neit her the blister nor the residual wound occurred with an alleviated scar after the Ac tivSkin treatment. Conclusion ActivSkin can promote wound closure, prevent blister and residual wound, and alleviate scarring on the donor sites of the splitthickness skin graft after the ActivSkin treatment.
OBJECTIVE: To investigate the efficiency of recombinant human epidermal growth factor (rhEGF) on burn wound healing and to explore the effective density of the ointments. METHODS: A total of 120 cases of burn in superficial II degree and profound II degree were randomly divided into 2 groups. In the first group of 15 cases of superficial II degree, the wounds were treated by rhEGF ointments of different density, 0.5 microgram/g, 10 micrograms/g and 50 micrograms/g, to screen out the effective density. And in the other 105 cases of the second group, optimal density of the ointments based on the result of the first group were employed to treat the burn wound in superficial II degree and profound II degree, with the self-corresponding wounds of the same degree as control, to study the efficiency of rhEGF on wound healing, according to the wound healing time, and adverse reaction of the ointment. RESULTS: In the first group, the average healing time of superficial II wound treated by ointments of 10 micrograms/g and 50 micrograms/g significantly shortened when compared with that treated by ointments of 0.5 microgram/g(P lt; 0.01), but there was no obvious difference between the cases treated by ointments of 10 micrograms/g and 50 micrograms/g. In the second group, the healing time of superficial II wound treated by ointments of 10 micrograms/g was (8.39 +/- 2.25) days, (9.52 +/- 2.56) days in the control (P lt; 0.01); and healing time of profound II burn treated by ointments of 10 micrograms/g was (16.80 +/- 2.99) days, (18.27 +/- 3.17) days in the control (P lt; 0.01). And healing rates of burn wound at different periods were higher than those of the control. CONCLUSION: The above results indicate that rhEGF ointments can enhance burn wound healing significantly, and the ointment of 10 micrograms/g is a good choice for clinical application.
Abstract From March, 1987 through May, 1996, a total of 13 cases of severe deep burn and bone defect of hand and wrist were treated by groin skin and iliac bone composite graft with vascular pedicle and had resulted in satisfactory result. The operation was relatively simple. Because thecomposite graft carried its own blood supply in the pedicle, it was not necessary to revascularize the composite graft by anastomosis of blood vessel during operation. Owing to the presence of abundant vascular supply of the iliac bone, the antiinfection potency was high, so its application was suitable for those conditions such as fresh severe deep burn with infection and bone defect. As a result, this technique gave the best chance to save the limb from amputation, and the duration required for treatment could be markedly shortened. This method provided the possibility to solve effectively the difficult problem dealing with the treatment of severe deep burn with infection and bone defect of the hand and wrist.
