BACKGROUND: The aim of this study is to evaluate the long-term results of Muzi's tension free primary closure technique for pilonidal sinus disease (PSD), in terms of patients' discomfort and recurrence rate. METHODS: This study is a retrospective analysis of prospectively collected data. Five hundred fourteen patients were treated. Postoperative pain (assessed by a visual analog scale, VAS), complications, time needed to return to full-day activities, and recurrence rate were recorded. At 12, 22, and 54 months postoperative, patients' satisfaction was evaluated by a questionnaire scoring from 0 (not satisfied) to 12 (greatly satisfied). RESULTS: The median operative time was 30 min. The overall postoperative complication rate was 2.52%. Median VAS score was 1. The mean of resumption to normal activity was 8.1 days. At median follow-up of 49 months, recurrence rate was 0.4% (two patients). At 12 months' follow-up, the mean satisfaction score was 10.3 ± 1.7. At 22 and 54 months' follow-up, the score was confirmed. CONCLUSIONS: Muzi's tension free primary closure technique has proved to be an effective treatment, showing in the long-term follow-up low recurrence rate and high degree of patient satisfaction. Therefore, we strongly recommend this technique for the treatment of PSD.
