Vestibular disease | Histopathological findings | Reference |
---|---|---|
Benign paroxysmal positional vertigo (cupulolithiasis) | A granular, basophilic staining homogeneous calculus measuring 350 μm in greatest dimension is attached to the posterior surface of cupula of the posterior semicircular canal. | [8] |
All other vestibular sense organ appeared normal. | ||
Measles labyrinthitis | Pathologic changes consist of severe degeneration of the organ of Corti, spiral ganglion, and vestibular sense organs. | [11] |
The saccular wall had collapsed on to the macula. There were large areas of hair cell loss and deposits of amorphous basophilic material. Distorted sustentacular cells were trapped between the collapsed wall and the stroma of the macula. | ||
Vestibular neuritis | Severe atrophy of the superior division of the vestibular nerve and the degenerated ampullary branch were showed. The crista, including the sensory epithelium, appeared normal. | [16] |
The cochlea appeared normal. | ||
Meniere’s disease (vestibular fibrosis) | A dense layer of sparsely celluar noninflammatory and avascular fibrous tissue between the dilated saccular wall and stapes footplate was showed. | [19] |
