With the change of people’s living habits and the popularization and improvement of diagnostic techniques, the incidence of malignant tumors of skin and other soft tissues has been increasing in recent years, and surgical excision is one of the most fundamental and effective means or tools for the treatment of such tumors. Up to this point, maybe people still don’t understand what this has to do with plastic surgery. As we all know, for malignant tumors, the scope of surgical resection is usually larger and deeper, and some of the surrounding normal tissues should also be removed at the same time, this technique is called extended resection surgery, only in this way can we prevent the recurrence of tumors. The problem is that when the tumor is removed, the oversized tissue defect is often difficult to be directly sutured and needs to be repaired by flaps or implants, and this technique is usually in the hands of plastic surgeons. There are also some important parts of tumors, such as face, breast, hands and feet, perineum, etc. The shape after resection and repair is very important, and it is difficult for non-plastic surgeons to achieve a perfect repair. Therefore, in large general hospitals with plastic surgery department, plastic surgery department takes up most of the tasks of surgical treatment of complex body surface malignant tumors. Therefore, it is not surprising that with the accumulation of health knowledge and education, more and more patients are coming directly to plastic surgery for consultation and treatment.
