Treatment of adolescent pilonidal disease with a new modification to the Limberg flap: symmetrically rotated rhomboid excision and lateralization of the Limberg flap technique.

Background/purpose: Pilonidal disease is a common and frustrating problem among adolescents due to its high recurrence rate. The rhomboid excision and Limberg flap techniques promise successful results, but the lower part of the incision left on the intergluteal sulcus is prone to recurrences. Consequently, we have developed a new modification to this technique and have designed a descriptive prospective study to evaluate its efficiency.
