Labyrinthitis Treatment in Burlington: Symptoms, Diagnosis & Recovery

What is labyrinthitis?

Labyrinthitis is an inflammatory condition of the inner ear that affects both the vestibular system (responsible for balance) and the cochlea (responsible for hearing). The inflammation disrupts signals from the inner ear to the brain, producing sudden vertigo alongside hearing changes — a combination that distinguishes labyrinthitis from the closely related condition vestibular neuritis.

The key difference is anatomical. In vestibular neuritis, the inflammation is confined to the vestibular nerve, so only balance is affected. In labyrinthitis, the inflammation extends to the labyrinth — the interconnected network of fluid-filled channels that houses both the balance organs and the cochlea. Because both systems share this space, labyrinthitis produces vestibular symptoms (vertigo, imbalance) and cochlear symptoms (hearing loss, tinnitus) together.

Labyrinthitis is most commonly caused by a viral infection, often following a cold or upper respiratory illness. Less commonly, it can result from a bacterial infection, which tends to be more severe and requires urgent medical treatment. In either case, once the acute phase has passed, vestibular rehabilitation therapy plays a central role in recovery.

Common symptoms

• Sudden, severe vertigo — a continuous spinning sensation that can last hours to several days, similar to vestibular neuritis
• Hearing loss or muffling in the affected ear — typically one-sided, and often most noticeable in the first few days
• Tinnitus — ringing, buzzing, or hissing in the affected ear
• Nausea and vomiting during the acute phase
• Difficulty walking or standing due to significant balance disruption
• Nystagmus — involuntary, rhythmic eye movements
• Blurred vision or difficulty focusing during head movement
• Lingering unsteadiness and dizziness that may persist for weeks or months after the acute vertigo subsides

The presence of hearing changes is the hallmark feature that separates labyrinthitis from vestibular neuritis. If you experienced sudden vertigo without any change in hearing, vestibular neuritis is the more likely diagnosis. If vertigo arrived alongside hearing loss or new tinnitus, labyrinthitis is the probable cause.

How we diagnose it

At Burlington Vestibular Therapy, your physiotherapist will conduct a thorough vestibular assessment to evaluate the nature and extent of your condition. This includes:

• Detailed symptom history — reviewing the onset, severity, and timeline of your vertigo and hearing symptoms, along with any preceding illness or infection
• Head impulse test — a quick head turn to assess the function of each inner ear. A corrective eye movement (catch-up saccade) on one side indicates reduced vestibular function, consistent with labyrinthitis or vestibular neuritis.
• Nystagmus assessment — observation of your eye movements at rest and during gaze to identify patterns typical of a unilateral vestibular loss
• Balance and gait testing — standardized assessments to measure how the vestibular deficit is affecting your stability and mobility
• Hearing screening — noting any subjective hearing changes. If hearing involvement is identified or suspected, your therapist may refer you for formal audiometry with an audiologist to document the extent of any hearing loss.

The vestibular examination findings in labyrinthitis are very similar to those in vestibular neuritis — the distinguishing factor is the presence of cochlear symptoms. Your therapist will also screen for red flags that might indicate a more serious cause, such as bacterial labyrinthitis or a central nervous system condition, and refer you to your physician or an emergency department if needed.

How labyrinthitis is treated

Treatment for labyrinthitis follows two phases: acute medical management and post-acute vestibular rehabilitation.

Acute phase (physician-managed)

During the first few days, when vertigo is at its most severe, treatment is typically managed by your physician and may include:

• Vestibular suppressant medications (such as meclizine or dimenhydrinate) to reduce the severity of vertigo and nausea
• Anti-nausea medication if vomiting is significant
• Corticosteroids — sometimes prescribed to reduce inner ear inflammation, particularly if hearing loss is present
• Antibiotics — if a bacterial cause is suspected, urgent antibiotic treatment is essential

It is important that vestibular suppressant medications are limited to the first few days. Prolonged use can interfere with the brain's natural compensation process and delay recovery.

Post-acute phase (vestibular rehabilitation)

Once the acute vertigo has begun to settle — typically within the first one to two weeks — vestibular rehabilitation therapy becomes the primary treatment. The rehabilitation approach for labyrinthitis is the same as for vestibular neuritis, because the underlying vestibular deficit is similar.

At Burlington Vestibular Therapy, your programme will be tailored to your specific deficits and may include:

• Gaze stabilization exercises — training the vestibulo-ocular reflex (VOR) to restore clear vision during head movement. You will practise focusing on a target while moving your head at progressively faster speeds, retraining the brain to produce accurate eye movements.
• Balance retraining — structured exercises that challenge your postural control under increasingly difficult conditions: narrowing your stance, standing on unstable surfaces, reducing visual input, and adding head movements.
• Habituation exercises — controlled, repeated exposure to movements or visual environments that provoke dizziness, gradually reducing the brain's exaggerated response to these stimuli.
• Walking and functional mobility — progressing through real-world movement tasks such as walking with head turns, navigating obstacles, and managing uneven surfaces to ensure your recovery carries over into daily life.

Recovery timeline

Recovery from labyrinthitis follows a similar trajectory to vestibular neuritis, with the addition of hearing considerations:

• First 1–3 days: Acute vertigo is at its most intense. Medical management is the priority during this phase.
• First 1–2 weeks: The continuous spinning sensation typically resolves, but significant unsteadiness, motion sensitivity, and fatigue remain. This is an appropriate time to begin vestibular rehabilitation.
• Weeks 2–8: With consistent therapy and a daily home exercise programme, most patients see meaningful improvement in balance, gaze stability, and overall function.
• 3–6 months: The majority of patients achieve a good functional recovery from the vestibular symptoms. Some may experience mild residual dizziness in demanding situations, which continues to improve over time.
• Hearing recovery: Hearing outcomes vary. Many patients with viral labyrinthitis recover some or all of their hearing over weeks to months, while others may have a permanent mild hearing loss in the affected ear. Your audiologist can monitor this over time and discuss options if needed.

Early initiation of vestibular rehabilitation — as soon as the acute vertigo begins to settle — is consistently supported by the evidence as the most effective way to promote recovery and prevent chronic symptoms.

Labyrinthitis vs vestibular neuritis

Because the two conditions are so closely related and frequently confused, it is worth highlighting the key differences:

In practical terms, the vestibular rehabilitation programme is the same for both conditions. The main clinical significance of distinguishing between them is that hearing involvement in labyrinthitis may warrant audiological follow-up and, in rare cases, urgent medical intervention if a bacterial cause is suspected.

If you have been diagnosed with vestibular neuritis but also noticed hearing changes, it is worth mentioning this to your therapist, as it may indicate labyrinthitis rather than neuritis.

When to seek vestibular therapy for labyrinthitis

If you have experienced sudden vertigo accompanied by hearing loss or tinnitus — especially following a cold or viral illness — labyrinthitis is a likely cause. You should seek vestibular therapy if:

• Your acute vertigo has settled but you continue to feel unsteady, off-balance, or dizzy
• Head movements provoke dizziness or blurred vision
• You feel worse in visually busy environments such as shops, traffic, or crowds
• Your balance has not returned to normal weeks or months after the initial episode
• You are avoiding activities due to dizziness or concern about falling

No physician referral is required to see a vestibular physiotherapist in Ontario. Book your vestibular assessment at Burlington Vestibular Therapy and take the first step toward recovery.
