Abstract Postburn deformities, including hypertrophic scars, scar contracture and defect or deformity of tissue or organ, are the commonest disorders in plastic surgery. It is also difficult to deal with. If the diformity involved multiple organs, oftentimes the teatmentis very difficult because the material for repair is limited and the donorsite usually could not provide adequate amount of skin for repair. Since 1978,2496 cases of various postburn deformities were admitted. In this article, theoptimal time to operate was discussed. The use of flap transfer and soft tissueexpander was described. Prolonged traction in the treatment of severe contracture of large joint was also described.
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 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.
OBJECTIVE: To investigate the repairing method of inguinal scar contracture deformity in children with transpositional fasciocutaneous flap of anterior-medial side of thigh. METHODS: From August 1989 to August 1999, 33 cases with inguinal scar contracture deformity were adopted in this study. Among them, there were 26 males and 7 females, aged from 3 to 11 years old. The transpositional fasciocutaneous flap consisted of a huge tongue-shape flap with a pedicled triangular flap between the edge of skin defect and the above tongue-shape flap. The maximal size of the transpositional fasciocutaneous flap was 18 cm x 10 cm and the minimal size was 13 cm x 8 cm, the transpositional angle was 60 degrees to 80 degrees. During operation, the tongue-shape flap was used to repair the inguinal region and the triangular flap was used to repair the donor site in one stage. RESULTS: All the flaps survived. The function and appearance of perineum were satisfactory. CONCLUSION: The transpositional fasciocutaneous flap is suitable for repairing the inguinal scar contracture deformity in children, and skin graft is unnecessary.

Methods Sixteen Sprague-Dawley (SD) rats were randomly selected, and deep partial-thickness burn with 20% of the body surface was inflicted. The rats were randomly divided into experimental group and control group with eight in each group. Rats in the experimental group were treated with abdominal injection of Shenfu injection at a dose of 20 mL/(kg•d) for five days continually, and rats in the control group were treated with the same dose of 0.9% saline solution. The growth of granulation tissue and collagen fibers were evaluated under light microscope at the seventh and the fourteenth day. The growth of fibroblast was observed under transmission electron microscope at the fourteenth day. The cure rate of both groups of rats at the seventh and fourteenth day was calculated. Then we compared their healing time and the cure rate of the traumatic wound respectively. Results All rats had survived until wound healing. The cure rate at the seventh day for the experimental group and the control group was (36.34±2.55)% and (33.13±2.62)%, and their difference was statistical (t=2.486, P=0.027); At the fourteenth day, the cure rate was respectively (75.71±2.29)% and (72.36±2.85)% with a significant difference between each other (t=2.590, P=0.022). The healing time of the experimental group (20.88±1.36) was significantly shorter than that of the control group (22.9±2.16) (t=-2.286, P=0.040). At the seventh and fourteenth day, light microscope observation showed that the growth of granulation tissue and collagen fibers for rats in the experimental group were much more than that in the control group, the basale cell proliferation was more active, and inflammation was slighter. Through transmission electron microscope, we observed more fibroblast and collagen in the experimental group, which showed a better cure than the control group. Conclusion Shenfu injection can significantly promote wound healing of deep partial-thickness burn. It may possibly get this effect through anti-oxidation.
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: With the recognization of the mechanism of wound healing, some topical agents are created and applied in trauma to improve the healing rate of wounds. The main purpose of this study is to investigate the effect of some topical agents on the healing rate of deep second-degree burn wounds. METHODS: One thousand five hundred and sixty-three patients with deep second-degree burn wounds(total burn surface area lt; or = 10%) were involved in this study from January 1982 to December 1999. According to the application time of different treating measures including supplement of Zn, application of growth factors and collagenase, the patients were divided into 3 groups, wound healing rates were compared. RESULTS: Before 1991, none of special topical agents were used, and the healing time of deep second-degree burn wounds was(23.8 +/- 3.5) days. From 1991 to 1996, with the topical application of SD-Ag-Zn, which can provide Zn for cells taking part in wound healing, the healing time of deep second-degree burn wounds was (20.6 +/- 3.2) days, earlier than no special topical agents (P lt; 0.05). From 1997 to 1999, growth factors such as basic fibroblast growth factor(bFGF) and epithelial growth factor (EGF) and collagenases were applied in wound treatment combining with SD-Ag-Zn, wound healing time was (16.2 +/- 2.8) days, earlier than no special topical agents (P lt; 0.01) and simple SD-Ag-Zn application (P lt; 0.05). CONCLUSION: It indicates that the improvement of topical agents can accelerate wound healing speed.
