Which of the following is the earliest sign to appear in acoustic neuroma?
High-Yield Explanation
The first symptom of an acoustic neuroma is hearing loss and the first sign diminished corneal sensitivity. Acoustic neuroma affects the trigeminal nerve, causing a diminished or absent corneal reflex, tinnitus, and unilateral hearing impairment. Facial palsy and anesthesia, palate weakness, and signs of cerebellar dysfunction may result if the tumor impinges on the adjacent cranial nerves, brain stem, and cerebellum.
