Pilonidal Sinus — Patient Information, Antalya

A subcutaneous tract over the sacrococcygeal area that may contain hair, presenting with discharge, pain, redness and abscess episodes.

It is often seen in young adults; hair-bearing skin, sweating, prolonged sitting, weight and family history are among the factors reported in the literature.

Diagnosis is clinical; imaging may be added in complex cases. Differential diagnosis includes perianal fistula and hidradenitis suppurativa.

Management depends on disease extent, presence of abscess, symptoms and previous interventions. No universal superiority between methods has been established for all patients.

• Crystallised phenol in selected, limited chronic disease
• More limited procedures such as pit-picking and laser-assisted techniques
• Excision with open healing, with the extent limited to the clinical finding
• Off-midline closure and flap techniques (Karydakis, Limberg)

Limited procedures may involve small entry openings and a smaller wound area; this is a characteristic of the technique. Individual pain experience, time away from work and complete healing of the tract and wound vary with the method, disease extent and anatomy, and cannot be guaranteed in advance.

ESCP 2024 classifies the evidence for laser surgery as very low. AWMF S3 2026 (https://register.awmf.org/assets/guidelines/081-009l_S3_Sinus_pilonidalis_2026-04.pdf) states that laser-based operations have no shown advantage over other minimally invasive methods and that the data rest largely on low-quality retrospective cohorts. In localised, uncomplicated chronic disease minimally invasive methods may be an option; however, recurrence may be higher than with excision methods.

In an active, tense and painful pilonidal abscess, the first step is prompt adequate drainage, preferably through a lateral incision. After the wound heals, observation may be sufficient in some patients; elective treatment is considered if chronic pain, discharge or a symptomatic sinus persists.

Method selection considers the number and direction of sinus openings, disease extent, previous operations and comorbidities together. Recurrence or previous surgery alone is not an absolute exclusion criterion for more limited techniques; however, flap procedures may be considered in complex anatomy.

Return to light daily activity and healing of the tract and wound are not the same thing. Some series report return to desk-based activity within days, while wound and tract healing may take weeks, discharge may persist for a while, and the course varies between individuals. Open healing requires regular wound care and review.

Laser epilation is not SiLaC. ESCP 2024 does not consider postoperative hair removal mandatory for everyone. AWMF 2026 recommends laser epilation alongside surgery for patients younger than 22, while no general recommendation can be made for older ages. The evidence for shaving and for laser epilation is not the same; hygiene, sitting habits and weight are assessed individually and a recurrence-reducing effect is not proven for every patient.

Rapidly increasing pain and swelling, fever of 38 °C or above, spreading redness, profuse malodorous discharge or deterioration in general condition require prompt medical attention.

Examination is necessary for diagnosis and for any individual treatment plan; the information here does not replace personal medical advice.
