Abstract:

Introduction to Meniere's disease is associated with endolymphatic hydrops of undetermined etiology, with the triad of symptoms: vertigo, tinnitus and hearing loss, which may be accompanied or not by feeling of fullness. The disease affects both gender, with a peak incidence between 20 and 50 years old. Vertigo is the most common symptom, 96% of cases, tinnitus 90%, 87% hearing loss and aural fullness in 74% of patients. Clinical case CSS, 40 year old female with complaints of hearing loss, tinnitus and aural fullness left for 6 years. Concerns have suffered TCE prior to the onset of symptoms. Pure tone audiometry revealed moderate sensorineural hearing loss in her left ear with normal hearing in right ear, bilateral discrimination of 100%. The ECoG showed increased amplitude of the potential summation with respect summation/potential action potential of 84%. The BERA was normal in both ears. Several authors propose a thread form of Meniere's disease in which only the symptoms are present ear (cochlea Meniere) and form an exclusively buccal, where only part of vertigo. However, the full form is the most common. In this case the examination of the ECoG strongly suggests the presence of hydrops. The possibility of partitioning the previous mazes (cochlea) and posterior (vestibular) can explain this kind of manifestation of the disease. CONCLUSION compartmentalized Endolymphatic hydrops in the cochlea is a subtype of Meniere's disease of rare incidence, making it difficult to identify, even for the expert.
