Tissue expanders have emerged recently as a new option for the treatment of alopecia. The method consists in expanding the scalp beyond the defective area. In this way, some disadvantages like the alterations in the donor area and low density of hair follicles, that may result from other techniques, are avoided. We present our experience with tissue expanders in the treatment of 32 patients with alopecia. The extent of these areas varied from 30 to 150 cm2, and the causes were: burn sequels in 12 patients; trauma sequels in ten; tumoral resections in ten; giant nevus pilosus in four and baldness (male standard) in two patients. The resection of the area with alopecia and the replacement by normal adjacent tissue was possible without any complications in all cases. However some disadvantages were observed. They included the necessity for a second surgical procedure because of marked deformity of the cephalic segment.
组织扩张器最近已成为治疗脱发的一种新选择。该方法包括将头皮扩张至缺损区域以外。通过这种方式，避免了其他技术可能导致的一些缺点，如供区改变和毛囊密度低。我们介绍了我们使用组织扩张器治疗32例脱发患者的经验。这些区域的面积从30到150平方厘米不等，病因如下：12例为烧伤后遗症；10例为创伤后遗症；10例为肿瘤切除术后；4例为巨大毛痣；2例为（男性标准型）秃发。在所有病例中，切除脱发区域并用相邻正常组织替代均未出现任何并发症。然而，也观察到了一些缺点。其中包括由于头部节段明显畸形而需要进行第二次手术。
