Subcutaneous lipoma removal surgery involves the complete removal of the lipoma under local anesthesia and suturing of the wound. Subcutaneous lipomas are generally benign tumors composed of mature fat cells, most commonly found in subcutaneous tissues of the neck, shoulder and limbs. Clinically, small subcutaneous lipomas do not need special treatment and regular checkups are sufficient. If the size is large, surgery can be considered, which is relatively simple. Generally, after local anesthesia with lidocaine, an appropriate incision is made on the surface of the subcutaneous lipoma. The lipoma is then removed free and intact, and the incision is then closed and the wound is dressed externally. To sum up, if the patient’s subcutaneous lipoma is large in size, it is recommended to go to the hospital for surgical treatment in time to avoid delaying the condition.
