Inelastic scalps in patients with male pattern baldness tax the ingenuity of the dermatologic surgeon in executing a satisfactory donor site closure without tension and subsequent wound dehiscence. The Radovan tissue expander permits the scalp to stretch slowly and facilitates the reconstruction of large scalp defects. Two cases are presented, illustrating this technique and its complications of pressure necrosis and expander extrusion. It is believed that this represents a significant advance in the field of hair replacement surgery.
男性型秃发患者的头皮缺乏弹性，这给皮肤科医生带来了挑战，他们需要巧妙地进行手术，在无张力的情况下实现满意的供区闭合，避免随后的伤口裂开。Radovan组织扩张器能使头皮缓慢伸展，有助于修复大面积的头皮缺损。本文介绍了两例病例，阐述了该技术及其压力性坏死和扩张器挤出等并发症。据信，这代表了毛发移植手术领域的一项重大进展。
