Abstract

hors suggest plausible mechanisms of the contralateral side BPPV after mastoid surgery as follows. Surgical position during mastoid surgery (contralateral ear down) and postoperative bulky mastoid compressive dressing usually kept the patient’s head to the contralateral side can be precipitating factors for migration of detached particles into the semicircular canal of dependent position. Anyway, appropriate differential diagnosis and management plans should be prompted using bed side vestibular evaluation, since serious irreversible inner ear complications are more frequent cause of postoperative vertigo than BPPV.
