Sebaceous cysts that are still hard after drainage are considered to be caused by incomplete drainage, inflammation and infection, scarring and hyperplasia.
1. Incomplete drainage: When sebaceous cysts are drained, the contents and walls of the cysts are not completely removed and drained out, which may result in some of the cysts remaining in the body, thus resulting in the situation of sebaceous cysts still hard after drainage.
2. Inflammation and infection: Inadequate postoperative wound care may lead to infection, and when stimulated by inflammation, the local tissues will become congested and swollen, thus causing the phenomenon of hardness after sebaceous cyst drainage.
3. Scar hyperplasia: After drainage surgery, the wound will gradually heal and form a scar, which is raised and hard, therefore, there will be hardness after sebaceous cyst drainage.
Sebaceous cysts are still hard after drainage, we should consult a doctor for diagnosis in time and follow the doctor’s instructions.
