Post-Pilonidal Surgery Scars: What to Expect
Where the scar sits, how it heals week by week, how to care for it, and what a healed result actually looks like — so you know exactly what to expect before and after surgery.
Scar expectations, honestly
There is no version of pilonidal surgery that leaves no scar — but there is a meaningful difference between the closures available, and it is worth understanding before you choose a procedure.
Where it sits
With our flap-based repair, the scar sits in the midline where the cleft already runs, so it blends into the natural crease.
When stitches come out
Retention sutures around day 5; skin stitches at about 2 weeks. Both removals are typically painless.
When it is healed
If recovery goes smoothly, the wound is typically healed about 3–4 weeks after surgery.
How it matures
Like any scar, it is pinker and firmer early on and softens and fades over the following months.
What a healed result looks like
This is an actual patient after flap-based repair at the Pilonidal Institute. Notice where the scar sits: in the midline, following the natural gluteal cleft, rather than tracking laterally across the upper buttock.
Because our bilateral fasciocutaneous flap closes the wound in the midline and reconstructs the natural cleft, the line tends to be less visible at a glance than an off-midline scar. The cleft anatomy is preserved rather than flattened, which many patients prefer cosmetically.
Scar placement depends on the operation
Different pilonidal procedures leave very different scars — in location, size, and how they heal.
| Procedure | Where the scar sits | How it heals | What to expect long term |
|---|---|---|---|
| Open-wound excision | Midline, over the excised area | Left open and packed daily for 6–12+ weeks; heals from the inside out | Often a wider, deeper scar with tissue contracture from prolonged open-wound healing |
| Cleft lift | Off-midline — lateral to the cleft, across the upper buttock (by design) | Closed primarily; heals like a regular incision | A visible lateral line; the cleft is mechanically flattened, and some asymmetry is possible |
| Bilateral flap + ECM (our technique) | Midline, blending into the natural cleft | Closed with tie-over sutures over an ECM scaffold; no daily packing | A discreet midline line that follows the crease; cleft anatomy reconstructed and preserved |
How the scar heals
A general timeline after flap-based repair. Your surgeon will personalize it to your case.
Dressed, not packed
The closed flap is dressed but never packed. No direct sitting for 48 hours; stand, walk, or lie on your back, side, or stomach.
Retention sutures out
Around day 5, two retention sutures are removed — painlessly. After that, frequent showering is encouraged, especially after bowel movements.
Skin stitches out
At about 2 weeks the skin stitches come out, also typically painless. Then you see the surgeon every 1–2 weeks until healed.
Typically healed
If there is no wound breakdown, healing is typically complete about 3–4 weeks after surgery. A small percentage of patients develop a small lower-wound opening around weeks 2–3; routine care continues while it heals.
The scar matures
Early on the line is pinker, firmer, and more noticeable. Over the following months it softens, flattens, and fades toward your skin tone.
Final appearance
Most scars reach their settled, mature appearance within about a year. Sun protection and good skin care during this period help it fade as well as possible.
Simple habits that help your scar heal well
Consistency matters more than intensity. Follow your surgeon’s specific instructions first; these are the principles behind them.
Keep it clean and dry
Sponge bathe for the first 5 days and wipe to the front; once the retention sutures are out, shower frequently, especially after bowel movements.
Avoid direct pressure early
No direct sitting for 48 hours, then cushions or foam pillows with regular offloading every half hour until your surgeon advances you.
Control surrounding hair
At each visit we trim or shave surrounding hair. Continued hair control protects the healed area from the friction and debris that started the disease.
Do not pick or scrub
Let scabs and sutures come away on their own or at your visits. Picking at a healing line delays healing and can widen the scar.
Protect it from sun once healed
New scars darken easily with sun exposure. Once the skin is fully closed, keep the area covered or protected when it might see sun.
Keep every follow-up
Three visits within the first two weeks, then weekly until healed. Small issues caught early rarely become big ones.
We watch the scar heal with you
Patients see our team three times within the first two weeks and once a week thereafter until the wound is fully healed. At each visit we inspect the incision, trim or shave surrounding hair, and address even the smallest sign of irritation before it can slow recovery.
Out-of-state patients move from in-office to video checks after the first post-op visit, and we send your local provider a written briefing describing the closure, the suture-removal schedule, and what the wound should look like at each interval.
Call us if you notice
Increasing redness or warmth, new or worsening pain, drainage that is cloudy or foul-smelling, fever, or an opening along the incision. Day-to-day questions go through secure messaging; urgent concerns get a same-day call.
Worried about how your scar is healing?
Whether you had surgery with us or elsewhere, a virtual visit lets a specialist look at photos of the area and tell you whether what you are seeing is normal.
Back to the life you paused
A well-healed scar is the visible sign of the real goal: a durable repair that lets you sit, work, and exercise without planning around the next flare.
