Mute is not necessarily deaf.
Mute is the loss of speech function and deaf is the loss of hearing function. The presence of hearing function is the basis for learning language function. For people with congenital deafness, because they do not have hearing function after birth, they are unable to learn language, and thus they will be mute as a manifestation of loss of language function.
For the loss of language function due to acquired factors, the patient’s hearing function will not be affected, such as cerebrovascular disease, brain tumors and other diseases, affecting the language center can not speak, so this kind of dumb people are not necessarily deaf.
To summarize, congenital factors can lead to deafness and mute symptoms appear together, and the chances of deafness and mute symptoms appearing together due to acquired factors are small.
Deafness and mute symptoms belong to pathological phenomena, need to consult the otorhinolaryngology department, clear the cause of the disease, and then follow the doctor’s instructions for treatment.
