Tissue-sparing surgery aims to avoid unnecessary injury to the skin, blood vessels, nerves and other structures. Appropriate instruments, careful dissection and incisions adapted to the anatomy can help achieve this.
A particularly small incision is not automatically the safest choice. The surgeon needs a clear view and suitable access to the area being operated on. For some procedures, a larger approach may therefore be appropriate.
Even careful technique cannot rule out bleeding, infection, scarring or wound healing problems. The appropriate approach depends on the specific operation and the person's tissues. The term alone does not establish that a treatment is superior.
