Abstract

Background: In past 20 years, there is increase in mobile phone users from 12.4 million to about 5.6 billion i.e 70 % of the world's population.[1] Electromagnetic radiations emitted from mobile phone damages inner ear, cochlea and outer hair cells of inner ear and auditory pathway (AP).[2].

Materials and methods: Case control study. Group 1, N=30 subjects, using mobile smart phones since past 1-5 years and exposure time more than 2 hours per day. Group II included 30 subjects, using mobile smart phones for more than 5 years and exposure time more than 2 hours per day. Headache, tinnitus, or sensations of burning around phone-using were excluded. Brainstem auditory evoked potential (BAEP) done. Student Unpaired t test was used for analysis and chisquare test.

Results: Mean ± SD of absolute latencies (AL) of Brainstem evoked response auditory. (BERA) waves III, V and all interpeak latencies at 80 dB and 4,6,8 KHz in group 2 were delayed and significant as compared to group 1. All parameters were highly significant at 8KHz as compared to 4KHz in group 2.

Conclusion: Brain stem evoked response audiometry (BERA) detects hearing loss in smart mobile phone using subjects at higher frequencies i.e at 8 KHz early. Hence central neural axis involvement can be detected early by BERA.

智能手机用户的高频听力损失：病例对照研究

背景：[1]手机发出的电磁辐射会损害内耳、耳蜗、内耳外毛细胞和听觉通路（AP）[2]：病例对照研究。第一组，30 名受试者，过去 1-5 年一直使用智能手机，每天接触时间超过 2 小时。第二组，30 名受试者，使用移动智能电话超过 5 年，每天接触时间超过 2 小时。使用手机时出现头痛、耳鸣或灼烧感的受试者除外。进行了脑干听觉诱发电位（BAEP）测试。分析采用学生非配对 t 检验和秩方检验：(结果：与第 1 组相比，第 2 组的脑干诱发反应听觉波 III 波、V 波和所有峰间潜伏期（80 dB 和 4、6、8 KHz）的绝对潜伏期（AL）的平均值（±SD）均有所延迟，且差异显著：脑干诱发反应测听（BERA）可在较高频率（即 8 KHz）早期检测出使用智能手机的受试者的听力损失。因此，脑干诱发反应测听仪可及早检测出中枢神经轴受累情况。

期刊介绍： The Annals of African Medicine is published by the Usmanu Danfodiyo University Teaching Hospital, Sokoto, Nigeria and the Annals of African Medicine Society. The Journal is intended to serve as a medium for the publication of research findings in the broad field of Medicine in Africa and other developing countries, and elsewhere which have relevance to Africa. It will serve as a source of information on the state of the art of Medicine in Africa, for continuing education for doctors in Africa and other developing countries, and also for the publication of meetings and conferences. The journal will publish articles I any field of Medicine and other fields which have relevance or implications for Medicine.
