Definition

Noun: * Inflammation of the inner ear: A medical condition characterized by swelling and irritation of the structures within the inner ear (the labyrinth). This condition can disrupt the functions of balance and hearing.

Usage

• The term "otitis interna" is used in formal medical contexts to diagnose and describe a specific inner ear disorder.
• It is often contrasted with "otitis externa" (inflammation of the outer ear) and "otitis media" (inflammation of the middle ear).

Examples

• The patient's severe dizziness was diagnosed as otitis interna.
• Otitis interna is a potential complication of some systemic infections.
• Veterinarians also use the term; for example, a dog with a head tilt may be suffering from otitis interna.

Advanced Usage

• Clinical Presentation: The primary symptoms of otitis interna are often vestibular (related to balance), such as vertigo, nausea, vomiting, and nystagmus (involuntary eye movements). Hearing loss may also occur.
• Common Causes: It can be caused by bacterial or viral infections, which may spread from the middle ear (otitis media) or from other parts of the body.

Variants and Related Words

• Labyrinthitis: A synonym often used interchangeably with "otitis interna," specifically referring to inflammation of the labyrinth.
• Vestibular Neuritis: A related condition involving inflammation of the vestibular nerve, which shares similar symptoms but may not directly involve the cochlear (hearing) structures.

Synonyms

• Labyrinthitis
• Inner ear infection
