This chapter discusses vertigo and Ménière’s disease, where vertigo can occur from disorders of any of the three systems, vestibular, visual or somatosensory. Cardiovascular system, central nervous system, visual problems, otological problems or locomotive system disturbances can also induce the symptom of vertigo. Vertigo varies from a sense of mild imbalance to severe vertigo accompanied by nausea, vomiting, perspiration and diarrhoea due to vagal stimulation. Equilibrium is maintained primarily by the vestibular part of labyrinth. Final control of equilibrium is done by the cerebellum and cerebrum. Distortion of cochlear duct produces hearing loss while due to pressure changes, the labyrinth causes vertigo. Vestibular neuronitis is believed to be a viral infection of vestibular nerve causing giddiness, nausea and vomiting. In Ménière\'s disease there is hydropic distension of endolymphatic system and duration of attack varies from a few hours to a few days. Epley’s manoeuvre is very beneficial in the management of benign paroxysmal positional vertigo.
