Abstract: Trepanation has been used in scar treatment for a long time, mainly including trepanectomy, trepanation lifting and trepanation transplantation. For different types of scars, appropriate operation methods should be selected. Postoperative combined treatment with laser therapy, radiotherapy, local injection of glucocorticoid and other options is often better than single therapy, but currently there is no standard treatment plan for trepanation for scar treatment. This paper reviews the application of trepanation in different types of scar, in order to provide reference for clinical practice.

Key words: trepanation, scar, combination therapy
