Labyrinthitis is inflammation of the inner ear's labyrinth, usually after a viral infection, and it causes vertigo together with hearing loss and tinnitus — the hearing symptoms are what set it apart from vestibular neuritis, which spares hearing.
It is one of the specific causes behind the acute hearing loss covered in sudden sensorineural hearing loss, and it is worth understanding on its own because of how often it is confused with its look-alike.
What is inflamed, and why it matters
The inner ear's labyrinth contains both the cochlea (hearing) and the vestibular system (balance) in one interconnected structure. Labyrinthitis is inflammation of this entire structure — most often triggered by a viral infection of the upper respiratory tract, though bacterial infections (via meningitis or acute middle ear infection) and, less commonly, autoimmune conditions can also cause it. Because the inflammation involves the cochlea directly, labyrinthitis produces both vestibular symptoms (vertigo, nausea, imbalance) and auditory symptoms (hearing loss and tinnitus) together.
The distinction that matters clinically
Vestibular neuritis, a closely related and more commonly discussed condition, is often confused with labyrinthitis because the vertigo, nausea, and imbalance can look identical — and both differ from Ménière's disease, which involves fluctuating symptoms over time rather than a single acute inflammatory episode. The critical difference between labyrinthitis and vestibular neuritis: vestibular neuritis involves inflammation confined to the vestibular nerve itself, without the membranous labyrinth or hearing being affected — meaning true vestibular neuritis does not cause hearing loss, and tinnitus is at most an occasional, mild complaint rather than a core feature. Labyrinthitis, by contrast, directly involves the labyrinth including the cochlea, so hearing loss and tinnitus are expected, core parts of the presentation, not an occasional add-on. If you have severe vertigo paired with new hearing loss and tinnitus, that combination points toward labyrinthitis rather than vestibular neuritis, and is worth describing precisely that way to a doctor, because the same combination can occasionally be an early sign of stroke. Vertigo, dizziness and tinnitus covers the wider range of causes when balance and ringing arrive together.
What the tinnitus itself tends to look like
Cleveland Clinic lists ringing in the ears among the symptoms of labyrinthitis, alongside hearing loss, vertigo, nausea and vomiting, and involuntary eye movements (nystagmus), and the NHS counts it among the most common symptoms. Neither says how often tinnitus occurs, and this page does not put a number on it either: it is a common symptom, not a guaranteed one. The bacterial form is the less common one, and it is handled differently: the NHS notes that antibiotics do not help the usual viral kind, but that a GP may prescribe them if they think the infection is bacterial. Cleveland Clinic notes that permanent hearing loss is a common result in children who develop labyrinthitis as a complication of meningitis.
Recovery timeline
The acute phase — the severe room-spinning vertigo, nausea, and vomiting — typically peaks and then eases within the first few days, and many people feel better within a week or two. Full recovery, including milder lingering imbalance, can take up to six weeks. Hearing loss and tinnitus don't always follow the same fast timeline as the vertigo — some patients recover hearing fully as inflammation resolves, while others are left with some degree of persistent hearing loss or tinnitus requiring ongoing management, including hearing aids or the other tinnitus-focused approaches, once the acute infection itself has cleared.
What this means practically
- Sudden vertigo paired with new hearing loss and tinnitus is the specific combination that points toward labyrinthitis rather than vestibular neuritis — mention hearing changes clearly to whoever evaluates you, since it changes the diagnosis.
- The hearing part is the time-sensitive part. The US guideline on sudden hearing loss makes it a strong recommendation that clinicians distinguish inner-ear from conductive hearing loss when sudden hearing loss first presents, and emphasises testing hearing as soon as possible and within 14 days of symptoms starting.
- The vertigo itself typically improves faster than any hearing-related symptoms — lingering tinnitus after the dizziness resolves does not mean the whole condition is unresolved; they can be on different recovery timelines.
- Bacterial labyrinthitis is less common than the viral form, and treated differently — a GP may prescribe antibiotics if they think the infection is bacterial, and permanent hearing loss is a common result in children who develop labyrinthitis as a complication of meningitis.
