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

Notes on Meaning
While "otitis interna" literally means inflammation of the inner ear, its clinical use is strongly associated with the resulting symptoms of vertigo and balance disturbance. The term itself does not specify the cause (bacterial, viral, etc.).
