A fistula between the paranasal sinuses and the orbit as a late complication of orbital fractures is rare and may present with intermittent symptoms due to air passing into the orbit. A case note review of two patients with sino‐orbital fistula is presented. Two patients, 23‐ and 30‐year‐old males, presented with intermittent symptoms of globe displacement, diplopia or discomfort months after repair of an orbital floor fracture with a synthetic orbital floor implant. The symptoms occurred after nose blowing. They were both cured by removal of the implant and partial removal of the tissue surrounding the implant. A sino‐orbital fistula may complicate the otherwise routine repair of an orbital floor fracture, but may be cured by removal of the implant and part of the surrounding pseudocapsule.
