[Repair of nasal columella and tip defects by using great/second toe web flap].

OBJECTIVE

To study the methods and therapeutic effect of repairing deformity of nasal columella and tip by anastomosing its blood vessels with those of the great/second toe web flap.

METHODS

The donor site was the great/second toe web flap. Sewing the great/second toe web flap and nasal columella and tip together by using 5-0 silk thread, anatomizing facial artery and facial vein for three centimeters long behind submaximal, protecting lower jaw branch of facial nerve, separating a subcutaneous layer tunnel between nasal columella and one of facial artery and facial vein behind submaximal. Dorsal artery of foot, saphenous vein in the flap were anastomosed with the facial artery and facial vein behind submaximal through the tunnel under the subcutaneous layer.

RESULTS

All flaps survived, satisfactory therapeutic effect was obtained. Postoperative follow-up was 0.5-1 year. The reconstructed columella showed satisfactory contour, good texture and color, and good resistance to injury.

CONCLUSIONS

Great/second toe web flap is a ideal skin flap for repairing deformity of nasal columella and tip.
