Benign Paroxysmal Positional Vertigo
Benign Paroxysmal Positional Vertigo
Brief episodes of severe vertigo caused by sudden head movements.
Microscopic debris located in the posterior semicirrcular canal are thought to be the cause, no effective medications are available as yet.
Treatment involves postural retraining using sequence of predetermined head movements in order to move the microscopic debris from the posterior semicirrcular canal in the inner ear.
This is called the Epley manoeuvre. Another technique used in the treatment of BPPV is the Semont liberating manoeuvre, which involves a series of head and body movements used to move the debris from the posterior semicirrcular canal in the inner ear.
Avoiding provocative positions is important, as BPPV occurs when the patient lies on one earor the other or tips their head backwards to look up.
It eases when BPPV lasts a year, atympanotomy can be performed to divide the nerve to the posterior semicirrcular canal of the affected ear, this can provide relief, however there is potential to cause deafness.
