Scalp expansion has been combined with scalp reduction and flap procedures for the treatment of male pattern baldness. Expansion offers the advantages of a safe and reliable procedure, as well as more coverage in a shorter period of time. The techniques described involve bilateral temporal parietal occipital (TPO) expanders followed by either a frontal TPO flap and contralateral scalp reduction or bilateral TPO flaps. Both procedures leave areas of baldness in patients with more extensive losses (Juri classes II and II). Further expansion may be used for further coverage of residual bald areas.
头皮扩张术已与头皮缩减术及皮瓣手术相结合用于治疗男性型秃发。扩张术具有操作安全可靠的优点，并且能在较短时间内覆盖更多区域。所描述的技术包括双侧颞顶枕部（TPO）扩张器，随后进行额部TPO皮瓣和对侧头皮缩减术或双侧TPO皮瓣。这两种手术都会在脱发范围更广的患者（Juri II级和III级）中留下秃发区域。进一步扩张可用于进一步覆盖残留的秃发区域。
