Approximately 80% of vertigo is peripheral and usually due to a benign process; benign paroxysmal positional vertigo (BPPV) is by far the most common cause of peripheral vertigo. According to research, Meniere disease is about 10 times less common than BPPV; however, it is frequently overdiagnosed, whereas BPPV is largely underdiagnosed. Cholesteatomas are cyst-like lesions filled with keratin debris and are among the less common peripheral causes of vertigo, along with otosclerosis and perilymphatic fistula. Typically, cholesteatomas involve the mastoid and middle ear. Approximately 20% of all cases of vertigo are central. They are most often due to stroke.
