Mohs micrographic surgery is a procedure used to treat recurrent or difficult skin cancers by the sequential removal of thin, saucerized layers of tissue. These excised layers are sectioned on a microtome and examined microscopically, and maps are prepared to delineate areas of residual tumor as well as normal, uninvolved tissue. Due to this microscopic control, cure rates are extremely high for basal and squamous cell cancers. Because the technique spares as much normal skin as possible, the wounds produced are well suited for healing by secondary intention alone or by surgical reconstruction. A further benefit of the technique is that almost all cases can be done under local anesthesia alone and in an outpatient setting as well. This results in less morbidity and greatly reduced cost.
莫氏显微外科手术是一种用于治疗复发性或难治性皮肤癌的手术，通过依次切除薄薄的、呈碟状的组织层来进行。这些切除的组织层在切片机上切片并进行显微镜检查，绘制图谱以描绘残留肿瘤区域以及正常的未受累组织。由于这种显微镜下的控制，基底细胞癌和鳞状细胞癌的治愈率极高。因为该技术尽可能多地保留正常皮肤，所以产生的伤口非常适合仅通过二期愈合或手术重建来愈合。该技术的另一个优点是，几乎所有病例都可以仅在局部麻醉下且在门诊环境中完成。这导致发病率降低，成本大幅降低。
