Delayed surgery for blowout orbital fracture is challenging. Although the most important purpose of the surgery is to reduce the adhesions between the orbital contents and the sinonasal mucosa or the fractured bone fragments, it is more difficult to identify the adhesions in delayed surgeries than in fresh cases. Recently, cine MRI has been reported as a useful modality for identifying the adhesions. In this report, we describe delayed surgery for a case of blowout orbital fracture that was successfully performed with the help of preoperative cine MRI.
A 54-year-old man who presented to us with diplopia, had undergone reconstructive surgery for the facial bones, except for the orbit as he had not recognized diplopia at that time, at our department a year earlier. Preoperative cine MRI showed adhesions in the medial wall of the orbit, so that the reduction surgery was performed successfully. The postoperative eye movements improved immediately and the improvement has been maintained.
Cine MRI provided effective information to identify the adhesions. Delayed reduction surgery should be performed in cases of blowout orbital fracture if the adhesions can be identified, since it is strongly expected to improve the eye movements.
