Naso-orbital fistula and socket reconstruction with radial artery forearm flap following orbital mucormycosis

Invasive mucormycosis is an uncommon cause of orbital exenteration. Reconstruction of an exenterated orbit is a surgical challenge. The loss of eyelids, adnexal structures, and even surrounding skin causes significant facial disfigurement. The goal for reconstruction demands a symmetrical orbital cavity with good prosthetic rehabilitation. Multiple reconstructive options in the form of skin grafts, local flaps, and free flaps are available. However, none of them provide ideal reconstruction. Our patient not only had extensive soft-tissue loss and unstable lining but also a large naso-orbital fistula. Reconstruction for this complex defect was done using an adipofascial radial artery flap which not only closed the fistula but also provided soft-tissue bulk and good skin match. Radial artery forearm flap provides a simple, stable, and good reconstructive option postorbital exenteration
