Since November 1996, 20 cases of craniofacial deformities, either from congenital or traumatic, were treated with MEDPOR surgical implant made from a linear high density polythylene. The animal experiment had shown that the MEDPOR had good organotrophic characteristics allowing tissue ingrowth. The biocompatibility studies in vitro and in vivo had shown that the MEDPOR biomaterial was free from any observable systemic or cytotoxic effect. In the clinical application, it was found that the MEDPOR could be easily modeled and maintained. Because of the ability to induce tissuee ingrowth, the tenacity and stability of the material were enhanced. A total of seven cases of cranial defects, 8 cases of periobital defects or depressed periobital regions, 2 cases of traumatic auricular defects, 2 cases of traumatic saddle nose and 1 case of maldevelopment of mandible angle were treated. All of the cases were followed up for 6 months, the results were satisfactory.
The authors reported nine patients with burn scar contracture of head and face treated by operation. The varieties of operations ineiuded: (1) excision of the scar and primary closure of the wound; (2) excision of the scar and coverage of the wound with split or full thickness skin grafts; (3) excision of the scar and repaired by pedicled flap, and (4) skin expansion by expander, followed by excision the scar and transfer of the "more available skin flap" to the wound. According to certain characteristics of children, the choice of the time for operation, the indications of each methods, and some problems related to operation ahd been discussed.
【摘要】 目的 探讨肥胖人群减肥后体重急剧下降导致腹壁松弛行腹壁整形手术的疗效。 方法 2003年4月-2009年10月，24例减肥后体重下降导致腹壁松弛患者中男3例，女21例，年龄28~44岁，平均36岁。其中1例合并甲状腺功能亢进，1例合并糖尿病病史；20例均通过运动、控制饮食等方式致体重下降，4例接受胃减容手术后体重下降。体重下降稳定后至腹壁整形手术时间间隔2~4年，平均2.5年；减肥前至腹壁整形手术前体重下降37~67 kg，平均下降45 kg。手术采用屈髋位，切除松弛皮肤组织，收紧腹壁及腰部松弛组织，耻骨上沿皮瓣远端去表皮后与耻骨上沿骨膜缝合固定。所有患者随访5个月~2年。 结果 23例术后2周皮瓣完全成活，切口愈合良好，无切口感染；1例术后出现耻骨上切口约2 cm表皮裂开，换药2周后切口愈合，术后腹壁平整、对称，无皮下血肿发生。随访期间切口疤痕隐蔽，阴阜无上移，腹壁平坦、对称。 结论 该腹壁整形手术方式效果良好，术后并发症少，值得推广。From April 2003 to October 2009, 24 obese patients, including three males and 21 females, developed abdominal chalastodermia caused by weight loss. Their age ranged from 28 to 44 years old with an average age of 36 years. Among them, one had hyperthyroidism and one had a medical history of diabetes. Twenty patients lost weight by exercise and diet, while the other four lost weight through stomach reduction surgery. Time span from weight loss to abdominal plastic surgery was two to four years, averaging at 2.5 years. During the time from before weight loss until the surgery, weight loss ranged from 37-67 kg, averaging at 45 kg. The surgery adopted the position of bending hip. The loose skin was removed; abdominal wall and loose waist tissues were tightened; and the far end of flap without skin along the upper edge of pubis was sutured with the periosteum. All patients were followed up for a time ranged from five months to two years. Results Flaps survived within two weeks after the surgery, incision healed perfectly, and no infection occurred to the incision for all the patients except in one case, there was a 2 cm of skin fissure in the upper incision which was cured after two weeks of dressing. After the surgery, the abdominal wall was flat and symmetrical without subcutaneous hematoma. During the follow-up, scars were well hidden, mons pubis was not shifted upward, and the abdominal wall was flat and symmetrical. Conclusion The abdominal wall plastic surgery has a good clinical outcome with few complications, which is worth being popularized.
A new type of sillicon rebber, which is a semisolid pairof room temperature vuleanizing silicones,has been used in103cases in plastic surgery, including saddle nose, smallchin,and defect of faicial bone. Satisfactory clinical resultswere achieved in 100 cases. Wound infection occured in2cases and the silicon rubber evacuated. The silicon rubberbody was excised because of infection. No adverse reactionwas observed in 64 follow-up cases.
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 explore the effectiveness of hairpin shaped incision combined with cover-lifting flap in plastic surgery of huge fat pad on nape and back. Methods Between March 2019 and March 2023, 10 patients with huge fat pad on the nape and back were treated. There was 1 male and 9 females with an average age of 52 years (range, 39-57 years). All patients had soft tissue bulge on the nape and back. Preoperative MRI showed the subcutaneous fat thickening. The length of the longitudinal axis of the fat pad ranged from 10.0 to 25.0 cm (mean, 14.1 cm), the length of the transverse axis ranged from 6.0 to 15.0 cm (mean, 10.8 cm); the thickness of the fat pad ranged from 2.5 to 5.1 cm (mean, 3.9 cm). Under general anesthesia, the patient was placed in a prone position and a hairpin shaped incision was made. The flap was lifted to remove the fat pad according to the marked area. The dressing was changed every 2 days after operation. ResultsThe operation time was 35-110 minutes (mean, 72 minutes). The intraoperative blood loss was 35-80 mL (mean, 49.5 mL). The drainage tube was removed at 2-5 days after operation (mean, 3.4 days). All incisions healed by first intention without incision dehiscence, infection, subcutaneous bruising, hematoma, or other related complications. All patients were followed up 2-24 months (mean, 12 months). All patients had a good shape of the nape and back and no noticeable scar on the incision. According to the Vancouver Scar Scale evaluation criteria, the incision scar score was 3-5 (mean, 3.7) at 2 months after operation. Patients had good neck movement with no recurrence. ConclusionFor the huge fat pad on the nape and back, the plastic surgery using hairpin shaped incision and cover-lifting flap has the advantages of fully exposing the fat pad, concealed incision, simple operation, and natural shape of the nape and back after operation.

Methods The xenograft acellular dermal sheets were estimated by hemolytic test, subcutaneous and muscular embedding animal tests.The safety and functionality as filling materials were preliminary evaluated after embedded for 1, 2 and 4 weeks, compared with the control samples. Results The xenograft acellular dermal sheets had excellent blood and tissue compatibility, without any immunoreaction;the materials with different thicknesses had different degradation rates which could be utilized by stacking if necessary in application. Conclusion The xenograft acellular dermal sheets can be applied as tissue patch, and are potential to be employed in the fields of plastic and tissue rehabilitation.
