Off-midline Closure Errors as a Risk Factor for Recurrence Following Limberg Flap in Patients With Pilonidal Sinus

All patients with pilonidal sinus recurrent disease following Limberg flap reconstruction in the recurrent group were examined by the authors in each study center and high resolution close-up photos of the patients' sacrococcygeal area were taken. These photos were then sent to all authors to asses and reach a collective decision to classify the erroneous off-midline closure technique and precisely measuring the distance between the flap border and the midline in the cleft. Same evaluation method was applied to the patients in nonrecurrent group. Following the completion of the assessments, all digital data of the patients were permanently deleted.
