The specific steps of surgical excision are as follows: 1. Firstly, skin preparation of the head is performed, and local hair is removed as much as possible to fully reveal the lipoma and avoid incisional infection caused by more local skin hair. 2. Local skin anesthesia is performed along the longitudinal direction of the lipoma, and the scope of anesthesia is as wide as possible to avoid local pain caused by small anesthesia. After satisfactory anesthesia, the subcutaneous tissue is incised along the skin layer by layer, and the adhesions between the lipoma and the surrounding tissues are separated along the lipoma envelope. 4. The lipoma is completely peeled off, and the wound is thoroughly hemostatic. After it is clear that there is no active local bleeding, non-absorbable silk sutures are used to intermittently close the wound. 3-5 days later, the local wound is completely healed and the silk sutures can be removed.
