Extracutaneous hair root sheath cysts are also called sebaceous cysts. Patients suffering from this disease can be cured through conservative treatment and surgical excision. 1. Conservative treatment: If the cysts of the outer hair root sheath of the skin do not increase in size and do not have symptoms of redness, swelling and pain, they usually do not need special treatment, but they should be followed up regularly for observation. 2. Surgical excision: For patients with recurrent symptoms of redness, swelling and pain, and localized secretions, timely surgical treatment is recommended. Patients should remove all the cysts during surgery, but should pay attention to the thin wall of the cysts to avoid the residual cyst wall when removing to reduce recurrence. Patients with symptoms such as hot pain, redness and swelling before surgery should control the inflammation first before surgical removal. Most patients can be completely cured of sebaceous cysts through surgical treatment. However, it should be noted that before and after the surgery, some antibiotic drugs, such as cefaclor, should be taken under the guidance of the doctor. Dietary attention should be paid to not eat spicy stimulating food, to avoid affecting the local recovery. It is recommended that patients go to the hospital in a timely manner, under the guidance of the doctor to choose the appropriate treatment, the use of drugs need to follow the doctor’s instructions.
