Labyrinthitis is defined as:

1. Infection of the auditory nerve

2. Inflammation of the inner ear

3. Blockage in the ear canal

4. A condition causing total deafness

The correct answer is: Inflammation of the inner ear

Labyrinthitis is characterized specifically as the inflammation of the inner ear, which encompasses a structure known as the labyrinth. This intricate part of the ear plays a crucial role in both hearing and balance. Inflammation in this area can lead to a variety of symptoms, including hearing loss, vertigo, and tinnitus, as it disrupts normal auditory and vestibular functions. The other choices focus on different ear-related conditions that don't accurately represent what labyrinthitis entails. While the infection of the auditory nerve and total deafness concern hearing issues, they do not describe the inflammatory aspect of labyrinthitis. Similarly, a blockage in the ear canal refers to an obstruction rather than inflammation. Understanding the specific nature of labyrinthitis as an inflammatory condition helps clarify its distinct symptoms and potential treatments, facilitating better patient care and management.
