Excision of pilonidal sinus is typically performed as an outpatient procedure under local or general anesthesia, depending on the extent of the disease and patient preferences. The procedure may involve simple excision of the sinus tract or more extensive removal of surrounding tissue, depending on the severity of the condition. Post-operative care includes wound care, pain management, and monitoring for signs of infection or recurrence.

The excision of pilonidal sinus procedure involves several key steps. First, the patient is positioned appropriately, and anesthesia is administered. The surgeon then makes an incision over the sinus opening and carefully dissects down to the sinus tract. The tract is excised along with any surrounding infected tissue or debris. Hemostasis (control of bleeding) is achieved, and the wound is irrigated with saline solution. Depending on the size and depth of the wound, the surgeon may leave it open to heal by secondary intention or close it with sutures or skin flaps.
