A periosteal-temporalis fascia pedicle flap for repairing impending ocular perforations and extruding keratoprostheses

Abstract

We repaired four eyes in four patients with impending perforation using a vascular periosteal-temporalis fascia pedicle flap continuous to the periorbita of the orbital wall. Two eyes with extruding keratoprostheses, one eye with severe ocular surface dysfunction and a perforated, infected keratoplasty, and one eye with scleral ectasia were successfully reconstructed. Excellent visual acuity (20/25) was attained in one eye and functional visual acuity (20/100) was maintained in another. Structural integrity was maintained in all eyes. A vascularized flap was an excellent source of tissue for reconstructing eyes with impending perforation and scleral melting.
