What is otitis?

Inflammation of the sinuses
Inflammation within the eye
Inflammation within the ear
Abnormal discharge from the nose

The correct answer is: Inflammation within the ear

Otitis refers specifically to the inflammation of the ear. This condition can affect different parts of the ear, leading to various forms such as otitis media (inflammation of the middle ear) or otitis externa (inflammation of the outer ear, also known as swimmer's ear). The inflammation can be a result of infections, allergies, or other irritants and is often characterized by symptoms such as pain, discharge, and hearing loss. Understanding the terminology is key in medical contexts; "otis" is derived from the Greek word that means ear. This makes option C the correct definition for otitis, distinguishing it clearly from conditions affecting other areas, such as the sinuses, eyes, or nasal passages. As such, the other options relate to inflammation in different anatomical regions and do not conform to the definition of otitis.
