应用头皮扩张术治疗头皮缺损颅骨外露

Scalp expansion in treatment of scalp defect with skull exposure

作者应用头皮扩张术修复头皮缺损颅骨外露的创面。Ⅰ期扩张器植入切口可选择在正常头皮上。注水至额定容量。按每修得１ｃｍ２创面需４ｍｌ扩张器容量推算扩张器大小。Ⅱ期皮瓣转移时，去除坏死的颅骨外板，取出扩张器，转移皮瓣。本组５例，共设计８块皮瓣，术后均Ⅰ期愈合。随诊６个月～１年，有毛发生长。作者认为用该方法扩张后皮瓣覆盖颅骨修复头皮缺损，既治疗了疾病又避免了秃发。

We repaired the scalp defect and skull exposure with scalp expansion.The techingue consisted of two stages.First,expander was implaned an then N.S injected to its enough volume.The size of the expander was estimated by the formula that 1 cm2 needs 4 ml expansive volume. The incision was made at normal skin.Second flap was transfered. The expander was removed and the external skull which was necrotic severed.There were five patient with eight flaps at all,followed up for 6 months to 1 year. The hair grew. The results were satisfactory. This method not only treated the disease,but also avoided alopecia.
