Sebaceous cyst surgery is a procedure performed to remove a sebaceous cyst, which is a non-cancerous growth commonly found on the skin. These cysts develop from blocked sebaceous glands and often contain a yellowish, cheesy material called keratin. Surgery is typically recommended when the cyst becomes painful, infected, cosmetically undesirable, or when it grows rapidly.
Indications
Sebaceous cyst surgery is indicated for:
Large cysts that are causing discomfort or pain.
Cysts that are infected (indicated by redness, warmth, tenderness, or pus drainage).
Cysts that are cosmetically bothersome due to their size or location.
Recurrent cysts that have been drained multiple times but continue to refill.
Concerns about the possibility of a more serious condition, although sebaceous cysts are generally benign.
Procedure Steps for Sebaceous Cyst Removal
Preoperative Preparation
Evaluation: Physical examination of the cyst, assessment of its size, location, and any signs of infection.
Patient Instructions: Explanation of the procedure, including potential risks and benefits.
Anesthesia: Local anesthesia is typically used to numb the area around the cyst. In some cases, sedation may also be used, especially if the cyst is large or in a sensitive area.
Surgical Procedure
Incision: The surgeon makes a small incision over the cyst.
Cyst Removal: The cyst and its contents (keratin material) are carefully removed from the surrounding tissue. In some cases, the cyst wall is also removed to reduce the risk of recurrence.
Closure: The incision may be left open to heal on its own (healing by secondary intention) or closed with sutures, depending on the size and location of the cyst.
Postoperative Care
Dressing: A sterile dressing or bandage may be applied to the incision site.
Pain Management: Pain relief medications as needed.
Wound Care: Instructions on how to care for the wound, which may include keeping it clean and dry.
Activity Restrictions: Avoiding strenuous activities and heavy lifting for a few days to promote healing.
Follow-Up: A follow-up appointment may be scheduled to monitor healing and remove any sutures if they were used.
Risks and Complications
Infection: Risk of infection at the surgical site, especially if the cyst was infected before surgery.
Bleeding: Minor bleeding is common during and after the procedure.
Recurrence: Although uncommon, sebaceous cysts can recur if the entire cyst wall is not removed during surgery.
Scarring: Depending on the size and location of the incision, scarring may occur, which can fade over time.
Nerve Damage: Rare risk of damage to nearby nerves, causing temporary or permanent numbness or weakness.
Recovery
Immediate Recovery: Most patients can resume normal activities shortly after the procedure. Mild discomfort or soreness at the incision site is normal and can be managed with pain relief medications.
Long-Term Recovery: Complete healing of the incision typically takes a few weeks. Any stitches or dressings may be removed during a follow-up appointment.
Conclusion
Sebaceous cyst surgery is a straightforward procedure commonly performed to remove bothersome or infected cysts from the skin. It is generally safe and effective in relieving symptoms and preventing recurrence. Proper preoperative evaluation, careful surgical technique, and diligent postoperative care are essential for achieving optimal outcomes. Patients should follow their surgeon’s instructions closely during the recovery period to minimize the risk of complications and promote healing.
