Pilonidal Sinus Open Surgery | PristynCare

Risk Factors

Risk factors for pilonidal sinus disease requiring open surgery include:

• Deep natal cleft anatomy, which traps hair and debris
• Excess body or sacral hair, particularly coarse or curly hair
• Prolonged sitting, especially in drivers, cyclists, and desk workers
• Obesity, which deepens the natal cleft and increases friction
• Recurrence after previous pilonidal abscess drainage or excision
• Young males aged 15 to 35 years are most commonly affected

Who Needs Pilonidal Open Surgery?

Open pilonidal sinus surgery is recommended for patients with complex or recurrent pilonidal disease, multiple sinus tracts, large pilonidal cysts, or patients who have had repeated abscess drainage without resolution. It is also recommended for patients who have failed minimally invasive treatments. A colorectal surgeon will assess sinus extent using clinical examination and imaging before recommending the appropriate surgical technique.

Diagnosis

Diagnosis before open pilonidal sinus surgery includes:

• Clinical examination: Inspection of the sacrococcygeal region for sinus openings, pits, discharge, and swelling
• Probing of sinus tracts: A probe maps the extent and number of sinus tracts
• Ultrasound: To assess the depth and extent of sinus tracts and rule out abscess
• MRI: For complex or recurrent cases to map sinus tracts in detail before surgery

Pilonidal Sinus Open Surgery

Open pilonidal sinus surgery involves complete excision of the pilonidal cyst, sinus tracts, and all sinus openings under spinal or general anesthesia. The wound can be managed with open healing, primary closure, or a flap technique. Open healing has the lowest recurrence rate but requires longer wound care. Pristyn Care provides pilonidal sinus surgery using the most appropriate technique for each patient, with expert post-operative wound management to ensure complete healing.

Pilonidal Surgery Steps

1. Anesthesia: Spinal or general anesthesia is administered for complete patient comfort
2. Positioning: The patient is placed in the prone position with buttocks separated to access the natal cleft
3. Sinus mapping: All sinus openings and tracts are identified and probed
4. Excision: The pilonidal cyst and all sinus tracts are completely excised down to the sacrococcygeal fascia
5. Wound management: The wound is left open, primarily closed, or repaired with a flap depending on the technique chosen
6. Dressing: A sterile dressing is applied and the patient is discharged with wound care instructions

Recovery After Surgery

Recovery after pilonidal sinus open surgery depends on the wound technique used:

• Open wounds require daily dressing changes for 4 to 8 weeks until complete healing
• Primary closure heals faster, typically in 2 to 4 weeks
• Sitz baths or wound irrigation 2 to 3 times daily keep the wound clean
• Light activities can resume in 1 to 2 weeks; strenuous activity after 4 to 6 weeks
• Hair removal from the natal cleft during healing reduces recurrence risk

Complications of Surgery

Open pilonidal sinus surgery is effective but may involve the following complications:

• Prolonged wound healing (4 to 8 weeks) for open wound management
• Wound infection requiring antibiotic treatment
• Recurrence of pilonidal disease, particularly with primary closure technique
• Scarring and discomfort when sitting in the early recovery period
• Hematoma (blood collection) at the surgical site
• Suture dehiscence (wound opening) with primary closure
