Medial orbital blow-out fracture with entrapment.

Blow-out fracture of the medial orbital wall, concomitant with tissue entrapment, is a rare condition occurring in those sustaining blunt trauma. Clinical signs of swelling, ecchymosis, enophthalmos, or diplopia during medial or lateral gaze is suggestive of the condition. Diagnostic confirmation is obtained by forced duction testing and computed tomography. Treatment with medial orbital decompression and limited ethmoidectomy is recommended in order to obtain optimum return of function with minimal risk.
