There is no hearing loss or other neurologic symptoms.Disease is caused by a disorder of posterior semicircular canal though many patients have history of head trauma and ear infectionIt has been demonstrated that otoconial debris, consisting of crystals of calcium carbonate, is released from the degenerating macula of the utricle and floats freely in the endolymphThe condition can be treated by performing Epley's manoeuvre. The principle of this manoeuvre is to reposition the otoconial debris from the posterior semicircular canal back into the utricle.The manoeuvre consists of five positions.Position 1; With the head turned 45deg, the patient is made to lie down in head-hanging position (DixHallpike manoeuvre). It will cause vertigo and nystagmus. Wait till vertigo and nystagmus subside.Position 2. Head is now turned so that affected ear is up.Position 3.
