据20世纪90年代中期统计,全世界约有五亿耳聋患者;1995年统计,美国有2800多万人存在不同程度的听力障碍,约占总人口的10.9％;我国有多少耳聋患者很难估计,20世纪80年代末残疾人普查表明我国大陆有聋儿171万,其中7岁以下的74万,每年还要新产生聋儿2～4万,这一状况令人担忧。耳聋患者以耳蜗感觉细胞病变为多见,往往伴有耳鸣,部分病人可能因为耳蜗和前庭同时病变而伴有眩晕。由于耳蜗感觉细胞的不可再生性,感音神经性聋的治疗十分困难。
According to the statistics of the mid-1990s, there were about 500 million deaf patients in the world. In 1995, there were more than 28 million people in the United States with varying degrees of hearing impairment, accounting for 10.9% of the total population. It is hard to estimate how many deaf patients in our country The census of disabled persons in the late 1980s showed that there were 1.71 million deaf children in mainland China, of which 740,000 are under 7 years of age and 240,000 deaf children are newly born every year. This situation is worrying. Deaf patients with cochlear sensory cytopathy is more common, often accompanied by tinnitus, some patients may be due to simultaneous cochlear and vestibular lesions associated with dizziness. Due to the non-regenerative nature of cochlear sensory cells, the treatment of sensorineural deafness is very difficult.
