很多年来就已知道正常或异常的前庭迷路对压力变化很敏感。压力变化传递到迷路有三种方式:①痿管试验;②减低外界气压或吹张咽鼓管造成中耳相对性超压;③声压(Tullio现象)。作者通过简短回顾160多年来的有关文献,就这些前庭反应可能存在的生理上、理论上和临床上的含意进行讨论。由于对声压引起的前庭反应最少为人知,故重点放在这个方面。 1824年Flourens观察到给鸽子各半规管造孔触及
It has been known for many years that normal or abnormal vestibular labyrinths are sensitive to changes in pressure. Pressure changes are passed to lost in three ways: ① fistula test; ② reduce the external pressure or blowing eustachian tube caused by over-pressure in the middle ear; ③ sound pressure (Tullio phenomenon). By briefly reviewing more than 160 years of literature, the authors discuss the possible physiological, theoretical and clinical implications of these vestibular responses. Due to the sound pressure caused by the vestibular response is at least known, so focus on this aspect. In 1824 Flourens observed that pigeons were implanted in each semicircular canal
