MERF runs a sophisticated Vestibular laboratory with the latest VideoOculography (from Interacoustics-Denmark), one of the few in India with a dedicated team under Dr. Sathiya Murali, Consultant ENT Surgeon to assess, evaluate and treat patients with dizziness and balance dysfunction. Vestibular Evoked Myogenic Potentials (VEMP) is one of the latest facilities for assessment of vertigo. It is very useful for assessing the various causes of vertigo such as Meniere's disease, vestibular schwannoma, aminoglycoside ototoxicity. MERF is one of the very few centres in the country which performs surgery for vertigo – Trans labrynthine vestibular nerve section,Trans labrythine acoustic neuroma surgery,Vestibular neurectomy & Endolymphatic sac surgery. Vertigo OverviewVertigo is the feeling that you or your environment is moving or spinning. It differs from dizziness in that vertigo describes an illusion of movement. When you feel as if you yourself are moving, it's called subjective vertigo, and the perception that your surroundings are moving it is called objective vertigo. Unlike nonspecific lightheadedness or dizziness, vertigo has relatively few causes. Causes of vertigoVertigo can be caused by problems in the inner ear or brain. When to Seek Medical Care?• Any signs and symptoms of vertigo should be evaluated by a doctor. The majority of cases of vertigo are harmless. Although vertigo can be debilitating, most causes are easily treated with medications. Have a doctor to check for new signs inorder to rule out rare, potentially serious, or life-threatening conditions. Vertigo DiagnosisBesides a thorough clinical examination and audiological tests we use the state of art Video Nystagmography (VNG) to evaluate the causes of vertgo/giddiness. How does VNG Work?VNG is a complete diagnostic system for recording, analyzing and reporting involuntary eye movements, called nystagmus, using video imaging technology. Hi-tech video goggles with infrared cameras are used. On an average we perform 180 tests/year. The main advantage of this procedure is that,it helps us to differentiate between the central and peripheral causes of vertigo . It also assesses the cochlear reserve which inturn would help us decide the nature of surgery to be performed for intractable vertigo. |
