Cleft lift surgery for pilonidal disease

At a glance

The cleft lift is a surgical technique for pilonidal disease that works by reshaping the natal cleft — the groove between the buttocks where pilonidal disease develops. Rather than simply removing the diseased tissue and leaving an open wound, the cleft lift flattens the area, removing the environment that allows the disease to recur.

It is increasingly recognised as one of the more effective surgical options for pilonidal disease, particularly for people with recurrent disease who have not had success with other approaches.

How it works

The principle

Pilonidal disease develops in the natal cleft because this area creates a warm, moist, enclosed environment where loose hair can become embedded and cause infection. The deeper the cleft, the more prone the area is to disease.

The cleft lift addresses this by:

1. Removing the diseased tissue — excising the sinuses, tracts, and any infected tissue
2. Reshaping the cleft — using a skin flap to flatten the area
3. Moving the wound off the midline — placing the surgical closure to one side, away from the deepest part of the cleft
4. Creating a flatter surface — so hair, moisture, and debris no longer accumulate

The procedure

• Performed under general anaesthesia
• The diseased tissue is excised
• A skin flap is raised from one side of the cleft
• The flap is advanced to cover the defect and flatten the area
• The wound is closed with sutures, with the scar line positioned off the midline
• A drain is typically placed to prevent fluid collection

The procedure usually takes one to two hours and is often done as a day case or with an overnight stay.

Who benefits most

The cleft lift is particularly considered for:

• Recurrent pilonidal disease — people who have had previous surgeries that failed
• Complex disease with multiple sinuses or extensive tracts
• Deep natal cleft — where the anatomy makes recurrence more likely with other approaches
• Failed open-wound healing — people whose previous wide excision wounds did not heal properly
• Primary treatment — increasingly used as a first-line surgical option

Recovery

Week 1

• A drain is typically removed within the first few days
• Wound care involves keeping the closure clean and dry
• Limited sitting — many people use a cushion or limit sitting time
• Pain is usually manageable with standard pain relief
• Light walking is encouraged

Weeks 2 to 3

• Sutures or staples may be removed
• Gradual return to normal sitting and light activities
• The wound is assessed for healing progress
• Most people can return to work (desk work) during this period

Weeks 3 to 6

• Full activities typically resume
• The wound continues to strengthen
• Follow-up appointments to confirm complete healing
• Hair removal in the area may be recommended to prevent recurrence

Long-term

• The flattened cleft reduces recurrence risk significantly
• Regular hygiene and hair removal in the area are commonly recommended
• Most people describe the area feeling different — flatter and less prone to the problems they experienced before

Success rates

The cleft lift has among the highest reported success rates for pilonidal surgery:

• Published studies generally report healing rates above 90 percent
• Recurrence rates are lower than for most other pilonidal procedures
• The off-midline wound closure is a key factor — midline wounds are more prone to breakdown

These rates are encouraging, though individual results depend on factors including disease complexity, surgical technique, and post-operative care.

Compared to other approaches

• Wide excision with open healing — higher recurrence rate, much longer healing time
• Bascom procedure — less extensive than cleft lift, may be suitable for less complex disease
• Karydakis flap — similar principle of off-midline closure, comparable outcomes in some studies
• Limberg flap — different flap design, comparable success rates for some disease patterns

The choice between these options depends on disease extent, surgeon expertise, and individual anatomy. The cleft lift is often favoured for recurrent or complex disease.

Finding a surgeon

The cleft lift is a specialised technique. Not all surgeons who treat pilonidal disease perform it. If you are considering a cleft lift:

• Ask your surgeon specifically about their experience with the cleft lift technique
• Some people choose to be referred to a surgeon with particular cleft lift expertise
• Published surgical outcomes can vary significantly between surgeons with different experience levels
• For recurrent disease, the expertise of the surgeon may matter more than the specific technique chosen
