Its incidence is 26 cases per 100,000 persons. Although many techniques have been described, there is no consensus on the treatment of pilonidal sinus disease (PSD). Materials and Methods: This study included 30 patients with PSD who were treated between May 2014 and September 2017. All cases underwent excision and flap reconstruction. The operative time, postoperative complications, the length of hospital stay, painless sitting and walking time, patient satisfaction and recurrence were evaluated prospectively. Results: The results of this prospective, randomized and comparative study are based on experience of a single surgical centre. All patients were followed up 18 months after discharge from the hospital. There is a difference in surgery durations (minutes) be- tween the two groups (33.86 ± 2.89 min. in “keystone” flap vs. 41.26 ± 4.19 in the “rhombic” flap group) (p = 0.001). There were no significant differences in the length of hospital stay, painless sitting and walking time or patient sa- tisfaction. The total complication rate was 66.6% after rhomboid flap com- pared with 6.6% after keystone flap. There was no flap necrosis. Conclusions: Both of these methods have shown to be successful in treatment of PSD. The KPIF is associated with the advantages of very simple design, abundant blood supply from the perforator vessels and lower rate of complication.
