Is intratympanic gentamicin effective for intractable Menière's disease?
Conclusions: Intratympanic gentamicin treatment for intractable Menière's disease appears to be effective in the relief of vertigo. Cochleotoxicity and ototoxicity is unlikely to be a major side effect. However, the level of evidence reflected from the eligible articles is insufficient, especially because of relatively poor study design.
Does gentamicin improve Vertigo in Meniere's disease?

How many intratympanic injections of gentamicin are needed for intrauterine injuries?
Variant intratympanic gentamicin procedures -- generally not good ideas Before beginning, it should be noted that in the past, most practitioners used the simple protocol of about 4 injections of gentamicin, delivered weekly, stopping when there is signs of damage (this is called titration).
Do intratympanic gentamicin injections for vertigo Cause Hearing loss?
Despite this, there is an increased chance of a hearing loss occurring with intratympanic gentamicin injections. For this reason, they are usually reserved for patients with a pre-existing severe hearing loss at the time the vertigo is diagnosed.
What happens after gentamicin injection for Meniere's disease?
Most patients experienced ototoxicity after 12 days of this treatment. About 50% of patients experienced worsening of hearing and about 40% of patients developed permanent perforations of their eardrums. These results are MUCH WORSE than those associated with single-dose gentamicin.
Does gentamicin cure Meniere's disease?
One-shot low-dosage gentamicin was effective in controlling vertigo attacks in Ménière's disease and has useful effects on aural fullness and tinnitus of patients as well. Postural and vestibular tests only have adjunctive role for monitoring therapeutic responses in intratympanic gentamicin-therapy.
How gentamicin works to alleviate the symptoms of Meniere's disease?
By selectively targeting the specialized cells of the balance organ, gentamicin can reduce the incidence of vertigo while preserving hearing in the ear. The effect of gentamicin injections is permanent—once the balance function (or hearing) is lost in that ear it does not return.
How long does Meniere disease take to heal?
It can take a day or 2 for the symptoms to disappear completely. You may feel tired after an attack. Symptoms vary from person to person, but an attack of hearing loss without vertigo is uncommon. Attacks can happen in clusters, or several times a week, or they may be separated by weeks, months or years.

How long does it take for gentamicin to work?
The disequilibrium will resolve in most patients over a period of several weeks after treatment with Gentamicin is stopped. In many cases, only a short 5-7 day course of treatment with Gentamicin is necessary. The temporary disequilibrium is described typically as the sensation most people feel coming off a small boat. The patient will automatically adjust with a broad-based gait (walking with legs apart). It is important for the patient to remain as active as possible since the inner ear will more quickly adjust to the new signals it is now receiving from the treated ear. Active movement speeds the centers in the brain to re-equilibrate to the new signal pattern coming from the inner ear.
Where is the antibiotic Gentamicin absorbed?
The Gentamicin is absorbed through the round window membrane in the middle ear and passes through this membrane and into the inner ear which contains the nerve endings of hearing and balance. Gentamicin is selectively more toxic to the nerve endings of balance than those of hearing and on a cellular level damages enough of the balance nerves to stop the vertigo attacks.
Does dexamethasone help with vertigo?
If dexamethasone perfusion of the inner ear has failed to control the vertigo of Meniere’s disease, the ear specialist may offer gentamicin perfusion of the inner ear as the next step in treatment. Gentamicin treatment is minimally invasive and also very effective in controlling the vertigo attacks in over 90% of Meniere’s disease cases ...
Can you hear loss from Gentamicin?
Unfortunately , it is not possible to accurately predict which patients will experience hearing loss due to the Gentamicin treatment. Studies over the past 10 years cite further hearing loss due to the Gentamyicin treatment in between 10-20% of patients treated. If further hearing loss occurs from Gentamicin perfusion the loss is usually not severe, however severe or even profound hearing loss in the treated ear can occur after even one Gentamicin perfusion.
Does Gentamicin perfusion help with vertigo?
Gentamicin perfusion is an optimal treatment for the patient with significantly decreased hearing in the involved ear, uncontrolled vertigo, and normal or near normal hearing in the opposite ear. In these patients the overwhelming objective is to make the vertigo attacks stop and Gentamicin perfusion will stop the attacks in over 90% of cases. However, a treatment dilemma may occur in the patient with aggressive, severe vertigo attacks that cannot be controlled with medical therapy who also has normal or near normal hearing in the Meniere’s affected ear.
How long does vertigo last after meniere's?

How is gentamicin given?
Injections of gentamicin are given through the ear drum, by way of a small needle. This is called "intratympanic gentamicin treatment". Some authors call the same process "transtympanic gentamicin" (e.g. Casani, Nuti et al. 2005), but the "intratympanic" term seems to be much more popular.
How long does it take for a second ITG injection to work?
The 2nd injection is given only if there has been a serious vertigo spell after at least 1 month post initial treatment-- usually 2 months. In other words, instead of titrating to the onset of damage to vestibular system (as is done for high-dose ITG/TTG), the criterion is a good effect on the disease.

Can intratympanic steroids be used for Meniere's disease?
A discussion of intratympanic steroids can be found here. Intratympanic steroids are not nearly as effective for Meniere's disease as gentamicin (Gabra and Saliba, 2013), but there are occasions when one does not want to commit quite yet to a "destructive" treatment.
Is TTG a labyrinthectomy?
Compared to labyrinthectomy, TTG treatment is also lower in risk because there is no need for general anesthesia. The main disadvantage of TTG compared to medical treatments is that it does damage to the ear. ITG/TTG has been advocated for other vestibular disorders than Meniere's disease (e.g. Brantberg et al, 1996).

Abstract
Ménière’s disease (MD) is an inner-ear disease mostly characterized by frequent spontaneous vertigo and fluctuating sensorineural hearing loss. The main purpose of treatment for MD is to reduce or control the vertigo while maximizing the preservation of hearing.
1. Introduction
Ménière’s disease (MD), also called idiopathic endolymphatic hydrops, is one of the most common causes of dizziness originating in the inner ear. The typical clinical manifestations are frequent spontaneous vertigo, fluctuating sensorineural hearing loss, tinnitus, and/or aural fullness.
2. History of intratympanic gentamicin
Aminoglycosides are highly potent, broad-spectrum antibiotics and are widely used by various routes of injection to treat serious infections caused by Gram-negative bacteria (e.g., Pseudomonas aeruginosa, Proteus species, Escherichia coli, Klebsiella-Enterobacter-Serratia species, and Citrobacter species), and are sometimes used as an adjuvant treatment for infections caused by Gram-positive bacteria (e.g., Staphylococcus species).
3. Mechanism of action
Aminoglycoside antibiotics have a well-documented history of cochleotoxic and vestibulotoxic effects.
4. Therapeutic method and treatment efficacy
Ménière’s disease is manifested by episodic vertigo, tinnitus, aural fullness, and fluctuating hearing loss. The treatment of patients with MD is usually directed at the most disabling symptom, which is the debilitating vertigo.
5. Indications and contraindications
Not all patients with MD can be treated with ITG. Based on the international consensus on treatment of MD obtained from the IFOS meeting 2017 [ 52 ], MD should be treated with a step-by-step therapy. The first line of treatment includes the medical conservative treatment, such as dietary modification and oral medicine.
Why might I need an intratympanic steroid injection?

What is an intra op steroid injection?
An intratympanic steroid injection is an operation in which a small amount of steroid is injected directly into the middle ear. It is used in patients suffering with severe vertigo, such as caused by Meniere’s disease or a sudden vestibular failure which has not responded to vestibular sedative medications or rehabilitation exercises.
Can you inject gentamicin in your middle ear?
In some instances, your specialist may recommend that you undergo an injection of gentamicin into the middle ear instead of a steroid. Gentamicin is an antibiotic which is known to have mildly toxic effects on both the balance and hearing parts of the ear, although its toxic effects on the vestibular system are very much more potent than on ...
