Ocular Muscle Injury During Ethmoid Sinus Removal
This exhibit depicts four axial conditions of the head during sinus removal surgery. Pre-operatively, the ethmoid sinuses are seen without evidence of disease. The medial and inferior rectus muscles are undamaged, and attached to the medial eye. A wrongful diagnosis of acute sinusitis was made, leading to unnecessary ethmoid sinus removal surgery. The nasal septum was straightened, and the left sinus cells were removed without complication. During right ethmoid sinus removal, the medial wall of the right orbit was fractured, transecting the right medial rectus muscle of the eye, and injuring the inferior rectus muscle. Resulting post-operative deficits include outward drifting of the right eye due to muscle damage, traumatic orbital hematoma, orbital wall fractures, and fluid buildup within the ethmoid sinuses.
