<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 25-year-old man is brought to the emergency department 30 minutes after he was involved in a motorcycle collision. He was not wearing a helmet. Physical examination shows left periorbital ecchymosis. A CT scan of the head shows a fracture of the greater wing of the left sphenoid bone with compression of the left superior orbital fissure. Physical examination of this patient is most likely to show which of the following findings?? A: Decreased sense of smell, B: Numbness of the left cheek, C: Preserved left lateral gaze, D: Absent left corneal reflex, E: Complete loss of vision of the left eye,  <response>: This is a clinical vignette describing a 25-year-old man who was in a motorcycle accident and sustained a head injury. He has a fracture of the greater wing of the left sphenoid bone with compression of the left superior orbital fissure. The superior orbital fissure allows structures like cranial nerves III, IV, V1, VI to enter the orbit and supply the extraocular muscles, eyelids, lacrimal gland, and cornea. Compression of this fissure can cause dysfunction of these structures.Choices A and B relate to cranial nerve I smell and V2 sensation of cheek, which do not pass through the superior orbital fissure. Choices C, D, and E all relate to dysfunction of cranial nerves that do pass through the fissure. Of these, compression would most likely cause dysfunction of CN V1 leading to loss of corneal reflex choice D. Complete loss of vision would be less likely.D: Absent left corneal reflex
