Skin grafts require a meticulous removal of subcutaneous fat from their underside to ensure their survival at the recipient site. Often a dermal layer is trimmed as well to improve the take of a skin graft or to adapt its thickness to the depth of a defect.
The authors present a new hand-held surgical device, the coriotome, that permits trimming a skin graft more evenly and in a considerably shorter period of time than by applying the conventional method using surgical scissors or a scalpel.
A total of 154 skin grafts (98 from preauricular, 45 from supraclavicular, and 11 from inguinal donor sites) were trimmed with the coriotome to a desired thickness. In 2 cases minor lacerations (<3 mm) of skin grafts occurred as a result of an inappropriate use.
The coriotome permits a fast and safe trimming of skin grafts.
皮肤移植需要从其底面细致地去除皮下脂肪，以确保其在受区存活。通常还会修剪真皮层，以提高皮肤移植的成活率或使其厚度适应缺损的深度。
作者介绍一种新型手持手术器械——皮刀，它比使用手术剪刀或手术刀的传统方法能更均匀且在更短时间内修剪皮肤移植片。
总共154块皮肤移植片（98块取自耳前供区，45块取自锁骨上供区，11块取自腹股沟供区）用皮刀修剪至所需厚度。2例因使用不当导致皮肤移植片出现轻微撕裂（<3毫米）。
皮刀能快速、安全地修剪皮肤移植片。
