Wounds after sebaceous cyst surgery usually need to be bandaged to avoid contamination or friction to the wound, which may affect healing or aggravate infection. Sebaceous glands open into the hair follicles or skin surface through ducts. If the ducts are obstructed or narrowed, secretions will be retained and accumulated, and the glands will gradually increase in size to form sebaceous cysts, which will become abscesses if secondary infection occurs. Sebaceous cysts occur on the head, face, neck and back of the neck, and are mostly solitary, while a few may be multiple. Sebaceous cysts are usually treated with cystectomy, postoperative bandaging, regular dressing changes and suture removal. If there is an associated infection with pus production, the abscess must be incised and drained, and a stage II excision is performed, during which the wound needs to be bandaged and the dressing changed regularly. After incision, all the cystic wall tissue needs to be adequately removed. When drainage is required in case of severe infection, the incision usually needs to be bandaged and cleaned with daily dressing changes. After control of the disease for larger incisions, the need for wound closure, the suture usually need to be bandaged to avoid external friction stimulation and contamination.
