FREQUENTLY ASKED QUESTIONS ABOUT PILONIDAL CYSTS
1. Do I have a pilonidal cyst?
A pilonidal cyst is a chronic subcutaneous abscess located at the bottom of the intergluteal cleft. A characteristic feature is the presence of hair within the sinus cavity, though this is not always present.
- Typical symptoms of a pilonidal cyst include (not all may be present simultaneously):
- Characteristic skin pits in the midline of the intergluteal cleft,
- Pain, erythema, and swelling in the sacrococcygeal region,
- A palpable lump in the skin, which may remain small and asymptomatic for a long time,
- Purulent or bloody discharge, often with an unpleasant odor,
- Possible inflammation or fever (in case of infection),
- Formation of a cutaneous fistula with purulent drainage,
- Occasionally, open and non-healing wounds.

2. What causes pilonidal cysts?
Several theories explain the formation of pilonidal sinuses. The most likely involves skin damage at the bottom of a tight, deep intergluteal cleft due to sweat and mechanical abrasion. This leads to secondary infection of superficial wounds, followed by bacterial penetration into the subcutaneous tissue, resulting in an abscess cavity connected to the skin surface via one or more fistulous tracts.
Despite the common theory of ingrown hairs, studies indicate that hairs found in pilonidal sinuses are loose hairs detached from the skin and trapped in the intergluteal cleft, often originating from the scalp. Many are short, stiff hairs with sharp ends, such as those cut at a barbershop, which penetrate the sinus through damaged skin or fistulas.

3. How can I manage symptoms at home?
If the issue is recent and you’re awaiting a doctor’s visit, you can try simple methods to feel better at home before receiving professional care. These are detailed on our blog.
4. How can I relieve pain before the procedure?
Pain from a pilonidal cyst can be significant, especially with inflammation or purulent infection. Several methods can help alleviate pain before professional treatment. These are detailed on our blog.
5. Why isn’t my wound healing after surgery? Is this normal?
The duration and course of recovery depend on multiple factors, including the type of procedure performed. Wounds from surgeries that do not involve flattening the intergluteal cleft may heal slowly or not at all, particularly if located between the buttocks with limited air exposure, preventing fluid evacuation. Wounds from procedures like the Bascom Cleft Lift, which flattens the cleft, typically heal quickly (2–3 weeks).
During healing, mild skin erythema is normal, but wound edges should remain soft and non-painful. Serous discharge (clear or slightly yellowish watery fluid) is part of the natural self-cleansing and healing process and is not concerning. However, if signs of inflammation appear—such as swelling, significant erythema, buttock induration, pain, or thick, white, or gray-brown malodorous pus—contact a nurse or physician.
6. What is the best treatment method for pilonidal cysts?
Various treatment methods for pilonidal cysts differ in wound healing speed, post-operative quality of life, and recurrence risk. Learn more about treatment planning and method selection on our procedures page.
7. What is surgical drainage, and is it necessary? How long is a drain needed?
A drain is a thin tube placed in the surgical wound to reduce discomfort, infection risk, and promote healing. Drainage typically lasts 5–10 days, though this varies individually. At Pilonidal Clinic by VenoMedica, we recommend drain removal for Bascom Cleft Lift patients when daily fluid output falls below 20 ml. Drains can be removed at home following instructions.
8. Can surgery be performed during active inflammation?
Inflammation is not an absolute contraindication to pilonidal cyst surgery, and patients with acute purulent infections may sometimes undergo surgery.
9. How long is a dressing needed after surgery?
The purpose of a dressing is to protect the surgical wound from bacterial contamination and external factors like sweat or clothing fibers. Dressing changes and wound care continue until healing, typically 10–14 days. Watch an instructional video on proper dressing changes after a Bascom Cleft Lift.
10. How long is the recovery period before returning to normal activities?
Most patients resume daily activities the day after surgery. After about two weeks, once the drain is removed and adhesive strips fall off, the wound is typically fully healed, allowing a return to normal life. However, the scar continues to strengthen up to six weeks. During this time, avoid activities that could injure the buttock area, such as falls, impacts, contact sports or long sopking (swimming pool, bath tube).
11. Can I travel by plane, car, or other transport immediately after surgery?
Patients can safely return home the same day after pilonidal cyst surgery, regardless of the mode of transportation (car, train, or plane), provided they feel well enough.
12. Can I return to work or school immediately after surgery?
Most patients resume daily activities the day after surgery. However, to avoid dislodging the drain or wound dehiscence, it’s sometimes better to wait until the drain is removed (5–10 days) before returning to work or school. The scar continues to strengthen for six weeks, during which activities risking buttock injury (e.g., falls, impacts, contact sports) should be avoided.
13. Can surgery be performed during antibiotic therapy?
Surgery can be performed while on antibiotics, but the decision depends on several factors, including the reason for antibiotic use (whether related to the pilonidal cyst or another condition) and the patient’s overall health. If fever, chills, or other systemic inflammatory symptoms are present, surgery may be postponed until the patient’s condition stabilizes. Decisions are made individually, prioritizing patient safety and comfort.
14. Is the surgery painful?
Pilonidal cyst surgery is performed under tumescent anesthesia, a type of local anesthesia involving the slow injection of a large volume of diluted anesthetic into the tissues around the surgical site. This effective method provides pain relief for several hours post-procedure, allowing patients to leave the facility immediately after surgery.
15. Will there be pain after surgery?
Some patients experience minimal pain that resolves within the first 2-3 days, while others may have discomfort for longer, particularly those with higher pain sensitivity or after more extensive procedures. Post-operative pain is typically transient. If needed, patients can use analgesics to manage discomfort, though approximately 80% of patients report no need for pain medication.
16. Do pilonidal cysts resolve with age?
Pilonidal cysts do not resolve with age. Although the condition may remain asymptomatic for extended periods, subclinical inflammation persists, and exacerbation—manifesting as pain, swelling, or purulent discharge—can occur at any time.
17. Can the Bascom Cleft Lift procedure be performed after multiple prior surgeries?
The Bascom Cleft Lift, which involves pilonidal cyst excision and flattening of the intergluteal cleft, permanently addresses a key cause of recurrence—the deep intergluteal cleft. It can be performed even in patients with multiple prior surgeries.
18. Why do methods other than Bascom Cleft Lift fail?
Simple excision of a pilonidal cyst is often insufficient, as recurrence is likely without addressing risk factors. The primary modifiable factor is the depth of the intergluteal cleft. Flattening the cleft, as in the Bascom Cleft Lift, reduces recurrence risk to below 5%. Methods that do not address cleft depth have a higher recurrence risk, up to 50% in some cases.
19. Is surgery necessary if the cyst is asymptomatic?
In some patients, pilonidal disease is asymptomatic and does not require surgical intervention.
20. How can I care for myself after surgery to minimize recurrence risk?
While the surgical method is the primary factor influencing recurrence risk, lifestyle also plays a role in recovery and prevention. Post-operative care includes:
- Daily hygiene of the surgical area,
- Avoiding prolonged sitting,
- Wearing breathable, natural-fiber underwear,
- Maintaining a healthy body weight.
21. I sometimes feel pain in the surgical area—does this indicate recurrence?
Post-operative pain does not always indicate recurrence. It is often related to scar tissue sensitivity in the subcutaneous tissue. Physiotherapy can be helpful in such cases.
22. Is ultrasound necessary to diagnose a pilonidal cyst?
A physical examination is typically sufficient to diagnose a pilonidal cyst. However, ultrasonography is the most effective diagnostic imaging method, allowing detailed visualization of a hair-filled cyst.
23. Is a pilonidal cyst hard or fluctuant on palpation?
A pilonidal cyst may feel either fluctuant or firm to the touch, depending on its characteristics.
