本文介绍了一种新的用于恢复Mb梅尼埃的基础感音神经性听力损失的技术。本文报告三位单侧基底感音神经性听力丧失、耳闷及耳鸣的病例。在疾病的急性阶段，患者在压力室中接受治疗，其中可以在+/- 110 cm H2O范围内增加或降低气压。检查中耳压力与周围气压的平衡。暴露于负压导致在低频率和主观症状的缓解听力阈值的上升。当空气压力增加时，听力阈值降低，耳鸣和耳闷的感觉加重。气压的变化不会影响健康耳朵或患病耳朵的高频。在暴露于负压下获得的听力改善似乎保持在大气压水平。本研究假设膜迷路扩张可能导致前庭水管静脉充血，导致内淋巴囊内淋巴吸收受损。讨论了环境气压变化对内耳的可能影响。
A new technique for the restoration of basal sensorineural hearing loss in Mb Meniere was described. Three cases with unilateral basal sensorineural hearing loss, fullness of the ear, and tinnitus were reported. In the acute stage of their disease the patients were treated in a pressure chamber where it was possible to increase or decrease the air pressure within the range +/- 110 cm H2O. The equilibration of middle ear pressures to surrounding air pressures was checked. Exposure to underpressure resulted in a rise of the hearing thresholds at low frequencies and relief of subjective symptoms. When the air pressure was increased the hearing thresholds were lowered and the sensation of tinnitus and fullness of the ear was accentuated. Changes in air pressure did not affect the healthy ears or the high frequencies in the diseased ear. Hearing improvement attained at exposure to underpressure seemed to remain at atmospheric pressure level. The investigation was performed on the hypothesis that a distended membranous labyrinth might cause a venous congestion of the vestibular aqueduct, resulting in impaired endolymph absorption in the endolymphatic sac. Possible effects of changes in environmental air pressure on the inner ear were discussed.
