Management
Management & rehab
There is no pill that grows back a vestibular organ. Stop whatever is still causing harm, then rebuild function through rehabilitation — and, for the worst-affected, watch the vestibular implant.
The principle
First, stop anything that is still damaging the balance organs — most importantly certain antibiotics. Then the main treatment is balance and eye-movement exercises that train the brain to cope using vision and the body’s position sense. Sedative “anti-dizzy” tablets do not help and can slow recovery.
Management has three strands. Stop the cause (discontinue the aminoglycoside; treat autoimmune or infective causes). Rehabilitate with supervised gaze-stabilisation and substitution training, which improve gaze stability, balance and gait.2 And avoid vestibular suppressants, which blunt the central adaptation rehabilitation depends on.1
Counsel realistically: rehabilitation reduces oscillopsia and improves function but rarely restores a normal VOR, and outcome is better with residual function than with complete areflexia. For severe, refractory bilateral loss the vestibular implant is the most promising horizon — it can evoke a measurable, frequency-dependent VOR in humans, though it remains investigational.3,4
The management ladder
Find and stop the cause; make vestibular rehabilitation the mainstay; then layer in practical strategies, aids and — where appropriate — emerging therapy.
Find & stop the cause
- Stop the ototoxinDiscontinue the offending aminoglycoside wherever possible — halting an ongoing insult is the single most important step.
- Treat treatable causesImmunosuppression for autoimmune disease, treatment of infection, and a search for CANVAS/genetic and neoplastic (NF2) causes.
- Confirm & documentEstablish the bilateral deficit with caloric, vHIT and/or rotational-chair testing before committing to lifelong management.
Vestibular rehabilitation — mainstay
- Gaze stabilisation×1 and ×2 viewing exercises drive adaptation and reduce oscillopsia; supervised programmes work best.
- Substitution & balanceTrain use of vision and proprioception, plus saccadic/pursuit strategies and balance work for gait stability.
- Avoid suppressantsVestibular sedatives blunt central compensation and worsen outcome — they have no role in chronic bilateral loss.
Strategies, aids & future therapy
- Practical strategiesGood lighting, walking aids, fall prevention, and caution with driving where head-movement vision is critical.
- Vestibular implantAn emerging neuroprosthesis for severe, refractory bilateral loss — investigational but restores a measurable VOR.
Stop any ongoing cause first, then rehabilitation is the mainstay — there is no drug that restores lost vestibular function. Reserve the vestibular implant for severe, refractory bilateral loss.
The course over time
Management unfolds from the work-up, through early and ongoing rehabilitation, to long-term strategies. Step through it:
Stop the offending aminoglycoside, treat autoimmune or infective causes, and screen for CANVAS/genetic and neoplastic causes. Halting an ongoing insult is the single most important step.
The rehabilitation programme itself is covered in Vestibular rehabilitation therapy; the functional impact of the VOR loss is quantified by dynamic visual acuity.
Key points
- Stop the cause first — discontinuing an offending aminoglycoside is the single most important step.
- Vestibular rehabilitation (gaze stabilisation + substitution) is the mainstay; supervised programmes work best.
- Avoid vestibular suppressants — they blunt central compensation and worsen outcome.
- Outcome is better with residual function than complete areflexia; the vestibular implant is an emerging option for severe loss.
