Scalp reduction has become an important part of the cosmetic surgeon's armamentarium in the treatment of male pattern alopecia. Recently, the use of two-stage tissue expansion has been advocated for scalp reduction. Intraoperative tissue expansion obviates many of the disadvantages of delayed expansion and increases the yield of excised scalp by 20-30% over standard reduction techniques in the 20 patients studied. The addition of hyaluronidase to the local anesthetic facilitates its diffusion, enhancing anesthesia and the ease of dissection. Therefore, the use of intraoperative tissue expansion and the addition of hyaluronidase to the local anesthetic are two separate adjuncts to scalp reduction surgery.
头皮缩减术已成为整形外科医生治疗男性型脱发手段中的重要组成部分。近来，有人主张采用两阶段组织扩张术来进行头皮缩减。术中组织扩张消除了延迟扩张的许多弊端，在所研究的20例患者中，与标准缩减技术相比，切除头皮的量增加了20% - 30%。在局部麻醉剂中添加透明质酸酶有助于其扩散，增强麻醉效果并使解剖操作更简便。因此，术中组织扩张的应用以及在局部麻醉剂中添加透明质酸酶是头皮缩减手术的两种不同辅助手段。
