The procedure consisted of an elliptical, wide, local excision, release of the coccycutaneous attachments and primary closure using dermal-subcuticular closure (XRD). Suction drains were used until drainage was minimal. The height of skin level at the lower angle of the wound from the coccyx was measured intra-operatively before and after division of the coccycutaneous attachments. Postoperatively, patients were assessed for hospital stay, return to normal activity, complications and recurrence. <\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p> Sixty-four patients (97%) were males, median age 27 years. The height of skin level rose from a mean of 1.8 cm (95% CI, 1.78\u20131.85) to a mean of 3.8 cm (95% CI, 3.77\u20133.88; P &lt; 0.001). Morbidity affected 12 patients (18%), epidermal separation of the lower wound angles (6 patients), seromas (5 patients) and 1 wound dehiscence at 2 weeks. All other wounds healed primarily without dehiscence. There were no recurrences after a median follow-up of 22.5 months (range, 12\u201338 months). <\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p> Release of the coccycutaneous attachments is an easy technique to learn, which seems to be an effective way of flattening the natal cleft and may result in lower recurrence rate. This technique should be tried in uncomplicated pilonidal sinus disease before more complex procedures are attempted.
