A retrospective study of treatment of orbital floor fractures with the maxillary sinus approach.

The Cook County Hospital, Chicago, Illinois, protocol for the management of orbital fractures is presented. Diplopia which fails to resolve in 1 week or appears after oedema subsides, enophthalmos or radiographic depression of the orbital floor, associated tripod fracture deformity, or purulent maxillary sinusitis are indications for surgery. The surgical procedure is a modification of the maxillary sinus approach, which includes the use of iodoform gauze packing, nasal antrostomy, a double layer oral closure and prophylactic antibiotics. A review of 102 patients treated surgically over a 6-year period is presented. Post-operative diplopia was 9% and there were minor complications in 3%, which were significantly lower than previously reported series of orbital fractures treated either non-operatively, or through an orbital exploration approach. No patient treated non-operatively required surgery in the future. The protocol presented can eliminate unnecessary exploration and yields excellent results with a simple surgical procedure.
