Sino-orbital fistulas can occur after orbital exenteration. Chronic nonhealing fistulas lead to bothersome symptoms including malodorous discharge, hypernasal speech, crusting, wound breakdown, or inability to wear an ocular prosthesis. Reconstruction can be difficult due to the complexity of the defects and the multitude of treatments patients often undergo for the management of the primary disease. Prior radiation, lack of available local tissue, or compromised blood supply are some of the issues that make successful fistula closure problematic. This report describes a method for autologous vascularized tissue coverage using a contralateral nasoseptal flap to successfully close a sino-orbital fistula.
