One of the questions that tinnitus patients often ask their doctors is: Am I going to be deaf? Among the patients we see, we find several situations: (1) Deafness and tinnitus coexist: In 1944, Fowler noted that tinnitus could be present in patients with normal hearing, but most patients (more than 90%) had hearing loss on audiological examination, which could be conductive, sensorineural or mixed. The cause of deafness is the same as the cause of tinnitus. For example, chronic otitis media, sudden deafness, and patients with otosclerosis. (2) Tinnitus does not match the degree of deafness: Some patients are so deaf that they can barely hear, but do not have tinnitus. On the contrary, there are patients with normal hearing but severe tinnitus, which even affects sleep, and in severe cases, suicidal tendencies. (3) The sequence of the appearance of tinnitus and deafness has important clinical significance. (4) The frequency of the dominant tone of tinnitus is very similar to the frequency distribution of deafness.
