Ear and ear canal anomalies are also related to this structure of the ear and are known to be associated with sensorineural hearing loss and conductive hearing loss. Vertigo refers to the inappropriate perception of motion. This is due to dysfunction of the vestibular system. One common type of vertigo is benign paroxysmal positional vertigo, when an otolith is displaced from the ventricles to the semicircular canal. The displaced otolith rests on the cupola, causing a sensation of movement when there is none. Ménière's disease, labyrinthitis, strokes, and other infective and congenital diseases may also result in the perception of vertigo.
Autoimmune inner ear disease cells that cause damage to the inner ear. There are several theories that propose a cause of AIED: Currently, the cross-reactions theory appears to be the favored mechanism of AIED pathogenesis. Since AIED symptoms are fairly common to many hearing loss disorders, it may be difficult to diagnose AIED without performing multiple medical tests. Some examples of these tests include: There are also blood tests specific to inner ear disorders: Though it has also been proposed that the use of anti heat shock protein 70 antibodies may be useful in the detection and diagnosis of AIED, there is not enough
