Many techniques have been described to treat sacrococcygeal pilonidal sinus disease in its chronic and acute forms. Appear to be the main problems associated with the closing techniques during the surgical treatment of this disease. The aim of this study, in patients with expansive sacrococcygeal pilonidal sinus (ESPS) was to analyse results of with triangular excision and the spider flap procedure. From Nov 2012 through Nov 2013, single centre a totaly 46 male patients were performed the with triangular excision and spider flap procedure for surgical treatment of ESPS. Patient datas were analysed retrospective. Patients with sepsis underwent surgery after treatment with the appropriate antibiotic. In the literature, we didn’t find a study made with the procedure for pilonidal sinus surgical treatment. We described a new effective repair method using the spider procedure for the excision of the pilonidal cyst. Within the scope of the study, a total of 46 male patients mean aged 26.5 (21-38) were treated with this technique. One of our patients (2.2%) developed recurrence. No flap rotation failures flap necrosis, incisional line maceration, delayed wound healing, or further complications were observed in an average of 8 month (6-11 months) follow-up period. Minimum postoperative morbidity and pain, short hospital stay and reduced time off work, satisfying esthetic outcome, and low recurrence rate make the proposed spider flap procedure an advantageous method for the treatment of ESPS.
