Pilonidal sinus surgery
is a procedure to treat a pilonidal sinus or cyst, a painful condition that typically occurs at the base of the spine. During the surgery, a surgeon makes an incision to remove the sinus tract, any hair, and infected tissue. The wound is then either closed with stitches or left open to heal from the inside out. Recovery can vary depending on the surgical approach but often involves wound care and a period of limited activity. Surgery aims to alleviate pain, prevent recurrent infections, and promote healing of the affected area.
