Journal Title: MedPulse -International Medical Journal - Year 2016, Vol 3, Issue 4
Abstract
Introduction: The word “vertigo” comes from the Latin word “vertigo”- to run, the suffix “- igo” = a condition of turning about). Vertigo is defined as the sensation of movement of self or environment. One of the most common presenting complaints patients bring to their family physicians and ENT surgeons is dizziness. In day-to-day ENT practice, incidence of dizziness is reported to be 10-15 %. Aims and Objectives: To Study Electronystagmographic of the Vertigo Patients. Material and Methods: This is a perspective study which was conducted in the Department of Otorhinolaryngology, tertiary care center. This study was done in tertiary care and Medical college. Data collection-18 months from January 2014 to June 2015.Data analysis-6 months from July 2015 to December 2015.Sample size included patients who presented with primary complaints of vertigo in our Otorhinolaryngology OPD. Sample size was 73 patients. All cases attending the ENT OPD with the vertigo, Patients with dizziness and vertigo, All age groups Both males and females included into study. Result: On non-caloric ENG test 3 patients showed smooth pursuit nystagmus abnormality on pendulum test and 3 showed asymmetric Opt kinetic test, 26 patients showed abnormal on positional test on 3 positions suggestive of BPPV. Butterfly chart showed 29 normal response which consists patients suffering from BPPV and a patient in which pathology was not located. 2 patients had B/L peripheral lesion. 20 patients showed RT vestibular lesion of which 5 were having ↓ RT cold response suggestive of Meniere’s disease. 16 patients showed Lt vestibular lesion of which 3 were having ↓Lt cold response suggestive of Meniere’s disease. Caloric response in 1 patient indicated B/L Brainstem lesion, 1 patient of RT Brainstem lesion, 1 patient of RT cerebellar lesion and 1 patient of Lt Cerebella. 2 patients showed no localization of pathology and considered as undetermined. Overall ENG findings showed normal response in 29 patients, peripheral lesion in 38 patients, central lesion in 4patients, no localization of pathology in 2 patients. Conclusion: Electronystagmographic Study of the Vertigo Patients is helpful for detection of type of lesion .i.e. peripheral or central and various causes of vertigo like Meniere’s disease, BPPV, and Brain stem lesion etc.
