Pilonidal Sinus Treatment

What pilonidal sinus is

Pilonidal sinus is a painful condition of the natal cleft, over the tailbone, known in Turkish as kıl dönmesi, or hair nesting. It starts when broken hair fragments work their way beneath the skin in the depth of the cleft. The body treats these hairs as foreign material and mounts an inflammatory response around them, which can lead to a cyst or an abscess forming under the skin.

On the surface, one or more small pits are visible; these are the openings of the sinus. The cavity beneath them gradually enlarges and collects hair and debris. For some people the only symptom is occasional discharge and mild discomfort; for others the first sign is a sudden abscess that makes sitting and walking difficult.

It is most common between late adolescence and the thirties, and more frequent in men. Long hours of sitting at work or while travelling, dense body hair, sweating, and repeated friction or minor trauma to the area all contribute. Contrary to a widespread belief, this is not a condition caused by poor hygiene; hygiene helps in managing it, but it is not the cause.

Symptoms and the abscess stage

Between episodes, the only finding may be small pits over the tailbone. Over time, clear, purulent or blood-stained discharge appears, staining underwear and leaving a persistent feeling of dampness. A dull ache that worsens after long periods of sitting is common.

When an abscess forms, the picture changes quickly: redness, obvious swelling, severe tenderness and sometimes fever. At this stage the priority is drainage, usually through a small incision, after which the pain settles rapidly. Drainage alone, however, is not definitive treatment. As long as the sinus cavity remains, the problem tends to return, so definitive treatment is planned once the inflammation has settled.

This is one of the conditions people most often postpone out of embarrassment, even though it interferes directly with school, work and travel. The consequence of postponing is repeated abscesses and an increasingly extensive sinus network. Presenting while the disease is limited makes it more likely that a smaller procedure will be enough.

Diagnosis

The diagnosis is almost always made on examination. Seeing the characteristic pits in the natal cleft, together with any discharge, is usually sufficient. We ask in detail about how extensive the sinus is, whether there are openings extending to one side, and about any previous abscess or operation, because all of these change the treatment plan.

Imaging is not routinely required. In recurrent, previously operated or unusually extensive disease, additional assessment of the area may be requested. Other conditions that can look similar are also distinguished at the time of examination.

Treatment options

Several methods are in use, including crystallised phenol application, laser treatment and surgical excision. The choice depends on how extensive the sinus is, how many openings there are, whether any procedure has been carried out before, and the practical demands of your daily life.

Crystallised phenol can be an option for patients with limited openings and a narrow cavity. The sinus is cleared and phenol applied; more than one session is usually needed, and healing is supported by wound care. Laser treatment closes the sinus cavity from within in a controlled way. The shared advantage of these minimally invasive approaches is a small wound and a faster return to normal activity, but they are not suitable for everyone.

Surgical treatment aims to remove the infected tissue and clear the area, and these procedures are generally performed under general anaesthesia. How the resulting defect is closed is an important decision: the wound may be left open to heal, closed directly, or closed with a flap technique that flattens the cleft. In extensive or recurrent disease, flap techniques that move the suture line off the midline are frequently preferred. These operations are planned carefully to improve comfort and reduce the risk of ongoing infection.

• Crystallised phenol application
• Laser closure of the sinus cavity
• Minimally invasive procedures directed at the sinus pits
• Excision with the wound left open to heal
• Flap procedures with an off-midline suture line

Recovery and wound care

Recovery in this area depends on proper care of the wound, and the timeline differs considerably between techniques. After minor procedures, return to normal activity is usually quick. Open wounds take longer to close and need regular dressings; after flap surgery the wound is generally closed, but some restrictions on sitting and activity are advised in the early period. These intervals vary from patient to patient.

Wound care is the single factor that most influences the result here. Keeping the area clean and dry, following the dressing schedule and attending review appointments are all expected. Avoiding long uninterrupted periods of sitting makes the recovery period easier. Fever, increasing redness or swelling, or new discharge should prompt contact with your surgeon rather than waiting.

Over the longer term, the priority is preventing recurrence. Reducing hair in the area, maintaining hygiene and limiting sweating all help lower that risk. When and how to use hair reduction should be discussed with your surgeon, and it should not be started before the wound has fully healed.
