title: Reconstruction of the natal cleft with a perforator-based flap.
abstract: Recurrent chronic conditions of the natal cleft, such as pilonidal sinuses, are difficult problems to treat. The deep natal cleft and the rolling effect of one buttock surface over the other contribute to the high recurrence rate. Wide excision of the affected area is the treatment of choice; to cover the defect many techniques have been described that flatten the natal cleft and shift the suture line away from the midline to try to reduce recurrence. These techniques include Z-plasties, rhomboid flaps, V-Y flaps, gluteus maximus myocutaneous flaps and others. Five patients with recurrent natal-cleft problems were operated on over a 1 year period. After wide excision of the natal cleft, the defect was reconstructed with a parasacral perforator-based flap. Preoperatively, a perforator situated superolaterally to the defect is identified with a Doppler probe; the flap is then designed horizontally around the perforator and, after elevation, is rotated 908 over the defect. The mean hospital stay was 5 days. Follow-up ranged from 3 months to 15 months, with no signs of recurrence. We believe this to be a simple and reliable technique, with the advantages of placing the scars away from the midline and flattening the natal cleft - factors that help to prevent recurrence.
