20例血管性耳鸣耳道音频检测分析

Analysis of auditory canal audio detection in 20 cases of vascular tinnitus

摘要:

目的 通过对经耳道记录的血管性耳鸣音频文件分析,验证自主研发的客观性耳鸣检测仪功能，并提出经耳道血管性耳鸣检测方案。方法 通过自主研发的客观性耳鸣检测仪,对20例临床判断为血管性耳鸣的自愿者经耳道检测并记录耳鸣音频,回放获得患者认可的资料判断为有效音频,并通过软件分析其音频特点。结果 共检测了20例患有血管性耳鸣的自愿者,都能通过外耳道探头捕捉到音频文件,通过回放音频其中17例得到患者确认。结论 本研究自主研发的客观性耳鸣检测仪通过放置于外耳道的高灵敏度探头可以捕捉到大多数客观性耳鸣的音频，为一种新的客观性耳鸣检测方案，可为耳鸣的临床诊治提供帮助；血管性耳鸣具有典型的节律性，但本研究自主研发设备尚无法精准分辨动脉和静脉性耳鸣。

Abstract:

Objective To analyze the audio files of vascular tinnitus recorded through the ear canal, this paper verified the function of the self-developed objective tinnitus detector, and proposed a detection scheme for vascular tinnitus through the ear canal.Methods A self-developed objective tinnitus detector was used to detect and record tinnitus audio through the ear canal in 20 volunteers, who were clinically diagnosed as vascular tinnitus. The audio characteristics were analyzed through software.Results A total of 20 volunteers with vascular tinnitus were detected, all of whom were able to capture audio files through the external ear canal probe. Seventeen of the cases were confirmed by replaying the audio.Conclusions The self-developed objective tinnitus detector can capture the audio of most objective tinnitus through a high-sensitivity probe placed in the external ear canal, which is a new objective tinnitus detection scheme. It can help the clinical diagnosis and treatment of tinnitus. Vascular tinnitus has typical rhythmic characteristics, and our equipment is still unable to accurately distinguish between arterial and venous tinnitus.
