Postoperative depression of the bone flap is a common and bothersome problem in craniotomies. In this paper, a simple technique to avoid this deformity is described. The key to this technique is to leave uncut a part of each osteotomy approximately 5 mm in width as a "bridge" to the bone flap, which is then subsequently cut with the aid of a chisel. This technique provides stable fixation of the bone flap and satisfactory cosmetic results with little additional operating time.
颅骨切开术中骨瓣术后凹陷是一个常见且棘手的问题。本文描述了一种避免这种畸形的简单技术。该技术的关键是在每处截骨处留出约5毫米宽的未切割部分作为骨瓣的“桥接”，随后借助凿子将其切断。该技术能实现骨瓣的稳定固定，获得满意的美容效果，且几乎不增加额外手术时间。
