If you are reading this website, you are probably looking for a better way to treat your pilonidal disease. Please read on…
Over the past century, many patients with pilonidal disease have received suboptimal care, as many medical practitioners (including surgeons) don’t fully understand the root cause of pilonidal disease and also underestimate its impact on the lives of young patients. Many doctors continue to believe that the cause of pilonidal disease is a congenital cyst (i.e., a cyst present from birth). This is not true. There is no cyst. Pilonidal disease is simply an infection under the skin between one’s buttock cheeks that typically arises from a trapped hair or fiber. It’s an acquired disease. It’s challenging to treat because of where it develops, the moist airless environment there, and the repeated pressure of sitting, and motion in the region.
Many surgeons choose to treat patients with disfiguring, wide-excisional operations hoping to resect the elusive cyst. The problem is that many of these radical operations: 1) don’t work and lead to a recurrence and, 2) even if they eventually fix the problem, have a long recovery which is often miserable for the patient and his/her caregiver. When these operations fail they often make the problem worse. Moreover, few surgeons want to tackle pilonidal disease. Even fewer care to operate on patients that have failed surgery from other surgeons.
Dr. Sternberg: premier expert in pilonidal disease
As I started my fellowship in 1999, I was one of those physicians who were reluctant to treat a patient with pilonidal disease. But the turning point came when I expressed this concern to an attending who knew of ‘a better way’ to treat the disease and invited me to join him for cases. From that time, and through visits with John and Tom Bascom, I learned a technique that made sense and worked. Since then, increasingly difficult cases obliged me to innovate variations that have led to my current technique. I now have a better way to cure pilonidal disease: I have extensive experience performing an operation called the Cleft Lift procedure (approximately 1,500 cases since 2002) and perform it regularly, curing almost 100% of patients. So why do I want to operate on patients with difficult pilonidal problems? 1) I truly am gratified when I improve a patient’s quality of life, and 2) the operation that I perform cures almost every patient, even when they’ve failed prior surgical attempts.
I am committed to helping cure pilonidal patients of their disease, and, in the long run, wish to change the way other doctors treat patients with pilonidal disease so these patients have access to reliable and appropriate care.
Pilonidal disease overview
Pilonidal disease (pie-low-NIE-dul), a chronic infection of the skin and underlying tissue near the tailbone, is a common disorder. It typically affects people in their teens, 20’s, and 30’s and often disappears by the age of forty. In its most severe form, pilonidal disease can be very debilitating, causing daily discomfort and limiting activity. Most operations reported to cure the disease are not reliable. Many sufferers of pilonidal disease become discouraged in their search for curative treatments as many surgeons, and medical practitioners continue to misadvise patients to consider disfiguring procedures with high recurrence rates.
This website provides basic information about pilonidal disease and its treatment. The most reliable and successful surgical treatment to date, the ‘cleft lift procedure’ is discussed in detail.
How this website can help:
You are likely viewing this website because you or someone you care about has pilonidal disease. Perhaps, you have already had surgery for a pilonidal abscess (often incorrectly referred to as a cyst), and the procedure didn’t turn out quite as well as you or your surgeon had anticipated. Maybe you’ve been told that you need surgery for a chronic pilonidal abscess/sinus or a recurrence after surgery and you want to educate yourself about the best options. This website should help you with this difficult decision: what the best surgical option is for 1) a chronic/recurrent pilonidal abscess/sinus, or 2) an unhealed wound or recurrent pilonidal disease after one or several pilonidal surgeries.
While this site provides a complete overview, it is not intended to be comprehensive. Excellent additional information including testimonials about specific procedures and chat rooms can be found at www.pilonidal.org.
This website should help you with this important decision: what is the best surgical option for...
1) Primary disease with multiple pits,
2) Primary disease with large pits,
3) Persistent or recurrent disease,
4) An unhealed wound after one or several pilonidal surgeries

Causes and symptoms of pilonidal disease
A nest of hairs
Pilonidal disease is not a cyst (an epithelial-lined sac), it is an abscess (a cavity filled with infected fluid and/or debris). The fluid, if present, is infected fluid called purulent material or pus, and the debris is usually loose hair. In fact, pilonidal means “nest of hairs.” Around half of all pilonidal abscesses contain hairs. The hairs are hairs from the cleft midline that have pulled inwards from their root end (not ingrown) through dilated, destroyed hair follicles, or shed from other parts of the body (such as the scalp, back, etc.) and then become lodged in an unusually deep cleft near the tailbone. They are not ingrown hairs. This is why shaving the affected area is usually of little help.
Symptoms of pilonidal disease
Pilonidal disease can cause a variety of symptoms which may happen all the time, may come and go, may be mild, or may be severe. These symptoms include:
- Pain/discomfort or swelling above the anus or near the tailbone that comes and goes
- Opaque yellow, white (purulent), or bloody discharge from the tailbone area
- Unexpected moisture in the tailbone region
- Discomfort with sitting on the tailbone, doing sit-ups or riding a bike (any activities that roll over the tailbone area)
Be aware that most physicians are not trained to differentiate pilonidal disease from a perianal abscess or buttock abscess. If you suspect that you have pilonidal disease, it is important to consult a Colon and Rectal Surgeon for a proper exam.
Pilonidal disease affects a very specific area of the body called the natal cleft or intergluteal cleft. Colloquially it’s the “butt crack”. The natal cleft is the 5-9 inch valley under the tailbone that is hidden by one’s buttock cheeks when standing. It is bracketed above by the top of the buttock sulcus (crease) and below, by the anus. The coccyx (tailbone) lies within it, and the edges (marked by the dashed lines) are the point of contact of the buttock cheeks when one stands.
Guide above – diagram of patient lying down with head up and legs below. The dotted lines are the edges of the buttocks cheeks that touch when one is standing. So, the space between the dotted lines demonstrates the depth of the natal cleft. The * represents the anus.
Guide above: Before surgery, the cleft is deep, moist, & poorly aerated – a perfect environment for infections to fester. The arrows indicate where the buttucks cheeks touch when relaxed or standing.
Guide above: After Cleft Lift Surgery, there is a well-aerated, shallow trough between the relaxed buttock cheeks. The incision (indicated by the *) is off to the side and in the open air so it will heal rapidly. The exposed trough resists infections, as the area is dry and exposed to the air.
Formation of abscesses
The abscess is believed to start when skin in the natal cleft stretches during sitting, breaking hair follicles and opening a pore or ‘pit.’ As one stands up, the movement causes a suction that pulls the original hair of the follicle or loose hair inwards from its root end (hair have barbs that prevent the apex of the hair from inserting) and debris into the now open ‘pore/pit’. Once lodged, the hairs can cause irritation if not expelled by the body or removed in time. Chronic infection can develop in this hidden area and lead to the formation of tunnels (sinuses) from under the skin to areas outside the natal cleft. Additional ‘pits’ can then develop leading to persistent or recurrent symptoms of pain, swelling, drainage, and even odor. Often, the pit’s become intermittently plugged with Keratin (a protein from the outer layer of skin), which encloses the infection, making it worse. Many people with pilonidal disease have or develop ‘divots’ in their natal clefts, which further encourage the deposition of debris and the formation of more ‘pits’.
Risk factors for developing pilonidal disease
The deep clefts of people with pilonidal disease
Pilonidal disease typically develops in people with very deep natal clefts that have poor air circulation as a result of the deep cleft. These deep clefts remain moist and airless – a perfect environment for infections. The only way to see pilonidal disease in these individuals is to part the buttock cheeks enough to visualize the pores within the valley of the natal cleft. The sinus opening, if present, is usually visible at the top and to one side of the cleft. Many healthcare practitioners mistake the sinus opening as the cause of the disease, but it’s the result of the disease, which is caused by the dilated pores.
Age and pilonidal disease
Pilonidal disease is common among young people. The disease most often affects teens and young adults. For unclear reasons, many, but not all, affected people will stop having symptoms of untreated disease by their 40s.
When pilonidal disease affects normal life
Pilonidal disease or failed surgical procedures aimed at treating the disease can lead to many months or years of discomfort, disability, and suffering. Due to severe symptoms of pain or discharge, affected individuals may have trouble sitting for long periods of time, miss school or work, refrain from sports, or avoid close contact with friends. Embarrassment from the condition may prevent individuals from using common locker rooms or wearing a bathing suit. Unsuccessful surgical procedures may force individuals to remain at home and pack wounds in areas they can’t see or easily reach.
