自主神经机能失调可能引起听觉紊乱的看法引起了人们对耳的交感神经分布的重视。神经分布可能影响血液供给,交感神经更可能促进传入听神经的活动。本文研究交感神经的作用对于维护正常听力是否必要。在实验用猫的同侧交感神经干和颈上神经节致伤前后,详细检查听阈。测定3只单耳实验用猫的绝对听阈和掩蔽听阈,然后在麻醉下切除同侧的颈上神经节和上交感神经干。术后三天开始检查,持续两年半时间,听力全无变化,证明没有交感神经的冲动,耳蜗可以保持正常状态。可以设想交感神经影响血液供给,或通过神经末梢作用于听神经。前段已经说明这两种情况 The notion that autonomic dysfunction can cause auditory disturbances draws attention to the distribution of sympathetic nerves in the ear. Nerve distribution may affect blood supply, and sympathetic nerves are more likely to promote afferent nerve activity. This article examines the role of sympathetic nerves for the maintenance of normal hearing is necessary. Listening thresholds were examined in detail before and after the experimental cat’s ipsilateral sympathetic trunk and supraspinatus injury. The absolute hearing thresholds and masking thresholds of three monaural experimental cats were measured, and then the ipsilateral supramaxillary ganglion and superior sympathetic trunk were excised under anesthesia. Three days after the start of examination, continued two and a half years, no change in hearing, that there is no impulse to sympathetic, cochlear can maintain normal state. It is conceivable that the sympathetic nerves affect the blood supply or act on the auditory nerve through the nerve endings. The preceding paragraph already illustrates both cases
