瘢痕治疗中皮肤软组织扩张器外露的原因分析

Causes of extrusion of skin soft tissue expander in treatment of scars

目的分析治疗体表不同部位瘢痕中皮肤软组织扩张器外露的原因。方法选取69例不同部位扩张器置入治疗瘢痕的患者,其中有11例扩张器外露,对外露的原因进行分析。结果头面颈部扩张器外露发生率为26.7%,四肢躯干扩张器外露发生率为7.7%;感染、切口选择不当、扩张囊的折角等可造成扩张器外露。结论头面颈部扩张器外露发生率高于四肢躯干扩张器外露;切口选择、解剖层次、扩张器的放置是预防扩张器外露的关键。

Objective To analyze the causes of extrusion of skin soft tissue expander in the treatment of scars on different body surface.Methods Expanders had been inserted in 69 cases suffering from scars.The extrusion of the expander occurred in 11 cases,and its causes were analyzed.Results The extrusion of the expander occurred in head,facial and cervical parts of 8 cases,which accounted for 26.7% of the total 22 cases.It occurred in trunks and limbs of 3 cases（7.7%）.Infection,inappropriate selection of incision,infolded dilation balloon could result in the expander extrusion.Conclusion The incidence of extrusion of expanders in the head,facial and cervical parts is higher than that in the trunk and limbs.Appropriate incision design,clear anatomic layer and correct placement of the expander are keys to prevent this accident.
