Dorsalis Pedis Free Flap for Eye Socket Reconstruction



Dorsalis Pedis Free Flap for Eye Socket Reconstruction


B. GUYURON

H. P. LABANDTER



Contracted or missing eye sockets, especially in an irradiated orbit, represent a major reconstructive task for the orbital surgeon. Failure of simple eye socket reconstruction requires complex procedures. Most grafts are doomed to failure, and local flaps may leave undesirable donor-site scars. Distant flaps require many stages and leave visible scars, and the patient is placed in an uncomfortable position for 2 or 3 weeks. In selected patients, we have transferred the dorsalis pedis flap to reconstruct the missing or contracted eye socket.





ANATOMY

For details of the anatomy of the flap (2, 3), see Chapters 316 and 548.


FLAP DESIGN AND DIMENSIONS

We use the central portion of the dorsalis pedis flap, the size of the flap depending on the size of the defect (Fig. 34.1A). Although the short and long saphenous veins can be used for the venous anastomosis, we prefer to use one of the venae comitantes of the anterior tibial artery because of its length and ease of dissection. The flap is designed with adequate dimensions to reconstruct the socket, as well as an additional de-epithelialized portion of the margin of this flap which is used to correct the periorbital deficit.
