What is a common symptom of acoustic neuroma?

• A. Sudden vision loss
• B. Unilateral hearing loss
• C. Chronic cough
• D. Severe headache

Answer: (B)

Unilateral hearing loss is a hallmark symptom of acoustic neuroma, which is a benign tumor that develops on the vestibulocochlear nerve (cranial nerve VIII), responsible for hearing and balance. As the tumor grows, it compresses this nerve, leading to progressive hearing loss in the affected ear. This symptom can vary in severity and may be accompanied by tinnitus, which is a ringing or buzzing sound in the ear.

Though other symptoms such as dizziness, balance problems, or facial numbness can occur due to the tumor's impact on nearby structures, unilateral hearing loss stands out as the key sign that is often the first indication of the presence of an acoustic neuroma. Understanding this relationship helps healthcare providers recognize the condition early, facilitating timely diagnosis and management.
