Peribulbar anesthesia for the repair of orbital floor fractures.

Four patients underwent successful repair of an isolated orbital floor fracture under local anesthesia. The surgical approach was by antero-inferior orbitotomy, with placement of a Nylamid plate (S Jackson Inc, Washington, DC). The anesthetic technique used was a peribulbar and infratrochlear nerve block with local supplementation. Digital control of the globe was maintained during the peribulbar injection to prevent ocular perforation. We conclude that local anesthetic for this procedure in carefully selected cases is safe and efficacious, avoiding the morbidity of a general anesthetic.
