The temporal bone collection at the Massachusetts Eye and Ear Infirmary includes specimens from several cases in which the only reasonable explanation for vertigo is collapse of the walls of the ampullae and utricle, a disorder we have termed vestibular atelectasis. The clinical histories and temporal bone studies support the existence of a primary type that may have a paroxysmal or insidious onset, and a secondary type that occurs in association with other inner ear disorders. The principal clinical symptom is chronic unsteadiness, precipitated or aggravated by head movement, and sometimes associated with short episodes of spinning vertigo. It is presumed that the collapsed membranes interfere with the motion mechanics of the cupulae and otolithic membranes.
马萨诸塞州眼耳医院的颞骨标本收集包含了几例病例的标本，在这些病例中，对眩晕唯一合理的解释是壶腹和椭圆囊壁塌陷，我们将这种病症称为前庭萎缩。临床病史和颞骨研究支持存在一种可能具有阵发性或隐匿性发作的原发性类型，以及一种与其他内耳疾病相关的继发性类型。主要临床症状是慢性不稳感，头部运动可诱发或加重，有时伴有短暂的旋转性眩晕发作。据推测，塌陷的膜会干扰壶腹嵴和耳石膜的运动机制。
