This study wants to improve patient care affected by pilonidal sinus during and after surgery. Pilonidal sinus excision is a frequent procedure, despite this, there is still not an appropriate surgical technique because of a lack of quality comparative studies.
This is a randomized controlled trial. The study will compare the healing of the surgical wound and the recurrence rate after excision and primary para-median closure versus narrow orifice excision (fistulectomy) Group A: excision and paramedian closure according to modified Karydakis technique Group B: removal / fistulectomy by scalpels or trephines of primary and drainage orifices, healing of the wound by secondary intention

Asymmetric skin incision and total excision of the lesion with monopolar scalpel. Accurate hemostasis, creation of a cutaneous-subcutaneous flap, primary closure with non-absorbable sutures, optional aspiration drainage.
Evaluation of the cavity using a 0.5-1 mm metal probe which will be inserted into the skin orifice. Excision of the skin around the orifice and debridement/excision of the cavity by monopolar scalpel or Trephines
