Also known as: Pilonidal abscess, Pilonidal dimple, Pilonidal disease, Pilonidal cyst or Pilonidal sinus
- Local anesthesia is used to numb the skin.
- A cut is made in the cyst to drain fluid and pus. The hole is packed with gauze and left open.
- Afterward, it can take up to 4 weeks for the cyst to heal. The gauze has to be changed often during this time.
- You may be given medicine (general anesthesia) that keeps you asleep and pain-free. Or, you may be given medicine (regional anesthesia) that numbs you from the waist down. In rare cases, you may only be given local numbing medicine.
- A cut is made to remove the skin with the pores and the underlying tissue with the hair follicles.
- Depending on how much tissue is removed, the area may or may not be packed with gauze. Sometimes a tube is placed to drain fluid that collects after surgery. The tube is removed at a later time when the fluid stops draining.
- Your doctor may recommend this procedure if you have pilonidal disease that is causing pain or infection.
- A pilonidal cyst that is not causing symptoms does not need treatment.
- Shaving or laser removal of hair around the cyst
- Injection of surgical glue into the cyst
- Taking a long time for the area to heal
- Having the pilonidal cyst come back
- What medicines, vitamins, and other supplements you are taking, even ones you bought without a prescription.
- If you are or could be pregnant.
- If you have been drinking a lot of alcohol, more than 1 or 2 drinks a day.
- If you are a smoker, stop smoking several weeks before the surgery. Your provider can help.
- You may be asked to stop taking aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve, Naprosyn), vitamin E, clopidogrel (Plavix), warfarin (Coumadin), and any other drugs like these.
- Ask your doctor which medicines you should take on the day of your surgery.
- You can go home after the procedure
- The wound will be covered with a bandage
- You will get pain medicines
- It is very important to keep the area around the wound clean
- Your health care provider will show you how to care for your wound
- After it heals, shaving the hair in the wound area may help prevent pilonidal disease from coming back
A pilonidal cyst is a pocket that forms around a hair follicle in the crease between the buttocks. The area may look like a small pit or pore in the skin that contains a dark spot or hair. Sometimes the cyst can become infected and this is called a pilonidal abscess.
An infected pilonidal cyst or abscess requires surgical drainage. It will not heal with antibiotic medicines. If you continue to have infections, the pilonidal cyst can be removed.
There are several types of surgery:
Incision and drainage: This is the most common treatment for an infected cyst. It is a simple procedure done in the doctor's office.
Pilonidal cystectomy: If you keep having problems with a pilonidal cyst, it can be removed surgically. This procedure is done as an outpatient procedure, so you will not need to spend the night in the hospital.
It may be hard to remove the entire cyst, so there is a chance that it will come back.
Why the Procedure is Performed
Surgery is needed to drain and remove a pilonidal cyst that does not heal.
Non-surgical treatment may be used if the area is not infected:
Pilonidal cyst resection is generally safe. Ask your doctor about these complications:
Before the Procedure
Tell your health care provider:
After the Procedure
After the procedure:
Pilonidal cysts come back in about half of the people who have surgery the first time. Even after a second surgery, it may come back.
