When the area of alopecia is very large, the normal scalp is not sufficient to cover the defect resulting from excision of the alopecia. From August 1987 to December 1989, 8 cases with large defect of scalp are repaired by means of expanded cross scalp flaps with good result. Among 8 cases, 7 are male and 1 female, and the largest area of alopecia is 300 cm2 and the smallest 112 cm2, with a mean of 191 cm2. Two expanders are buried under the galea aponeurotica on both sides of alopecia, and the scalp is expanded. The central part of the expanded scalp is chosen to form the "major flap", the lateral part of the expanded scalp to form the "adjuvant flap". Two flaps are then crossed and the defect is repaired. The method of scalp expansion and "axial flap" is used in marginal alopecia. An expander is buried under the galea aponeurotica on each side of the alopecia. After the scalp is expanded, the central part of the expanded scalp is chosen to from "axial flap" with the pedicle consisting of superficial temporal artery or occipital artery and the lateral part of the expanded scalp to form the "adjuvant flap". Then two flaps are transposed and the defect is thus repaired.
当秃发面积非常大时，正常头皮不足以覆盖因秃发切除而产生的缺损。1987年8月至1989年12月，应用扩张后的交叉头皮瓣修复8例大面积头皮缺损，效果良好。8例中，男性7例，女性1例，最大秃发面积为300 cm²，最小为112 cm²，平均为191 cm²。在秃发区两侧的帽状腱膜下埋置两个扩张器，扩张头皮。选择扩张头皮的中央部分形成“主瓣”，扩张头皮的外侧部分形成“辅瓣”。然后将两个皮瓣交叉，修复缺损。在边缘性秃发中采用头皮扩张和“轴型皮瓣”的方法。在秃发区两侧的帽状腱膜下各埋置一个扩张器。头皮扩张后，选择扩张头皮的中央部分形成以颞浅动脉或枕动脉为蒂的“轴型皮瓣”，扩张头皮的外侧部分形成“辅瓣”。然后将两个皮瓣移位，修复缺损。
