皮片

Methods 28 inpatients with all of 58 deep burn wound on the function part were selected in this study. After the eschar was removed with Goulian, the wound was covered with meshed skin, autologous split-thickness skin sheet.

对28例共58个功能部位深度烧伤创面，应用Goulian削痂后：深Ⅱ度创面予以整张或网状自体刃厚皮片移植；Ⅲ度创面予以脱细胞异体真皮加自体刃厚皮片复合移植术。

An area of (1.5×1.5) cm2 autologous full thickness skin graft model was made on the back of the all the rats. The color change of skin graft was observed at different time points. Meanwhile, whether hematocele and fluidify as well as binding to wound appeared under the skin graft were investigated.

所有大鼠背部制作(1.5×1.5)cm2面积的自体全层皮肤移植模型，在不同时间点观察移植皮片的颜色改变，移植皮片下是否有积血、积液，皮片是否与创面粘合。

Results The excellent rate of razor skin graft was 45.6% but the graft led to claw hands of different degrees, scar contracture and joint malformation; the excellent rate of flap graft was 100% with good function recovery and nice appearance; medium-thickness skin graft, full-thickness skin graft and composite skin graft showed out close results, the excellent rates were from 90% to 94%.

结果 刃厚皮片移植优良率45.6%，刃厚皮片移植术后，存在不同程度的"爪形手"、瘢痕挛缩、关节畸形等。皮瓣移植优良率100%，术后功能较好，外观优良。中厚皮片移植、全厚皮片移植及复合皮移植效果接近，优良率为90%～94%。

Part two: Urethroplasty by using skin oversleeve with vesicomucosa to treat hypospadias.

为解决单独使用膀胱粘膜尿道成形术后并发症较多的问题，我们设计了皮肤袖套式膀胱粘膜尿道成形术治疗重型尿道下裂及部分首次手术失败的尿道下裂患儿，即用游离包皮内板或游离阴囊中隔皮片在尿道外口处做成一短段尿道，然后用游离膀胱粘膜形成全段人工尿道并从包皮内板或游离阴囊中隔皮片做成的尿道内穿出。

Result: 245 cases had the skin grafts well survived and the wounds repaired with good appearance and function. 18 cases had scattered blisters and piebald changes, but the appearance and function were good. 3 cases had skin grafts necrotized.

结果：245例皮片成活良好，外形及功能恢复满意，18例出现散在水疱及花斑样改变，但外形及功能恢复尚满意，3例术后皮片坏死。

RESULTS: The skin flaps were survived completely in 50 cases, only 1 case was necrosis partially and healed after changing dressing. Forty-two cases were followed up for 16 months to 9 years (66 months in average), the varicosis and ulcer were healed in 39 cases and only 3 relapsed in ulceration.

结果 51例术后移植皮片全部成活50例，1例移植皮片部分坏死，经换药愈合。42例获得16个月～9年(平均66个月)随访，39例下肢静脉曲张和溃疡未复发，湿疹痊愈，疗效满意；3例溃疡复发，但未见下肢静脉曲张复发。

Among them,12 ears used epiderm had continous dilatation for 3～6 months,and no constrictive or atretic condition occured;7 ears used intermediate split thickness skin graft had no dilatation after operation,and no scars in donor;4 ears used skin flap had no dilatation after operation,and no constrictive or atretic condition in external auditory canal.

内容提要采用皮片和皮瓣为23耳行外耳道成形术，其中采用表层皮片12耳，术后持续扩张3～6月，未发生狭窄或闭锁；采用中厚皮片7耳，术后不扩张，供皮区无瘢痕增生；采用皮瓣4耳，术后未扩张，外耳道无狭窄或闭锁。

Results: The survival rate of all skin grafts except for skin graft on diploic layer, which was about 90%, were 100%. Three skin flaps and 15 expansive skin flaps survived and the wounds healed on the first stage. Any complication was not found.

结果：所移植的皮片除板障层移植皮片成活率约为90%外，其余皮片均100%成活；3个皮瓣和15个扩张皮瓣均成活，伤口一期愈合，无任何并发症发生，随访显示毛发生长良好，外形满意。

Methods The hyperpigmented intermediate-spl it-thickness skin grafts of 16 patients' face and cervicum 1 year after operation was harvested and the normal skins around the recipient site and the donor site were used as controls.

取患者自愿捐赠面颈部自体中厚皮片移植术后1 年的色素沉着皮片16 例，以自体移植皮片受区周围及原供区皮肤作为对照。

Free skin with subdermal vascularplexus after extreme expansion has advantages of small scar,supplying large area of free skin graft,which could be used in clinic.

扩张后含真皮下血管网皮片具有供区瘢痕小、可提供大面积皮片等优点，可在临床上推广应用。
