The Bascom pit-pick procedure is performed under local anesthesia with the patient in a prone position, taking approximately 15-20 minutes. Pre-operative preparation includes shaving and cleaning the surgical area. Local anesthesia (lidocaine with adrenaline) is typically used, with general anesthesia as an alternative if needed. The surgical technique involves excising midline pits with a scalpel, removing infected granulation tissue and hairs through curettage or a lateral incision. Midline wounds and nearby secondary pits are sutured with polypropylene, while the lateral incision is left open and covered with a hydrofibre bandage to heal by secondary intention.

The primary closure technique for pilonidal sinus involves placing the patient in a prone position under spinal or general anesthesia, shaving and cleaning the surgical area, and making an elliptical incision to remove the affected tissue. A skin flap is then mobilized from the surrounding area to cover the excision site, and the wound is closed with sutures.

The Karydakis primary closure procedure involves placing the patient in a prone position under spinal or general anesthesia. The surgical area around the natal cleft is shaved and cleaned thoroughly. A symmetric elliptical excision is performed 2 cm lateral to the midline, removing all affected pilonidal sinus tissue and some surrounding normal tissue. A skin flap, 2 cm wide and 1 cm thick, is mobilized from the contralateral side to cover the resultant defect. The flap is secured using a continuous suture technique, with the skin closed using polypropylene mattress sutures. A low-suction drain is used to standardize the procedure, removed when drainage decreases to less than 20 ml/day.

Bascom's Pit-Pick procedure, Primary Closure, Karydakis procedure

This measure evaluates the rate of pilonidal sinus disease recurrence in female patients undergoing Karydakis flap or Bascom's pit-pick surgical procedures over a 12-month period. Recurrence is defined as the reappearance of disease symptoms after the wound has completely healed.

This measure records the incidence of postoperative complications such as infections (superficial or deep), seromas, hematomas, wound dehiscence (partial or complete), and anesthesia-related complications within the first 30 days post-surgery.
