Both in my clinical work and online, I am often asked by patients and friends, “Is my deafness curable?” . Deafness can be divided into two main categories: 1. Sensorineural deafness: deafness caused by lesions in the inner ear or auditory afferent nerves. 2. Conductive deafness: deafness due to lesions in the outer ear or middle ear. In principle, there are ways to cure conductive deafness. However, at the current level of medical development, most of the sensorineural deafness cannot be cured by medication. Happily, the development of cochlear implants offers the possibility of curing sensorineural deafness in two groups of people: those with prelingual deafness under the age of 4-5 years, and those with postlingual deafness whose speech is fully developed. The other common type of sensorineural deafness, sudden onset deafness, can be cured in most patients with early and aggressive drug therapy.
