"If the hearing is not good, you should go to the hospital for an ear, nose and throat examination. The most routine examinations include electrical audiometry and acoustic immittance. Through basic examination, we can judge the degree and type of hearing loss. Generally, hearing loss can be divided into sensorineural deafness and conductive deafness. Different types of treatment are different. If it is sensorineural deafness, it may be difficult to treat. If it is short-term and sudden sensorineural deafness, it may be possible to restore hearing and even reach normal level through drug treatment and physical therapy. If you have long-term sensorineural deafness, you can use hearing AIDS. If it is bilateral extremely severe sensorineural deafness, it can also be treated by cochlear implantation. The most common cause of conductive deafness is tympanic membrane perforation or otitis media. It is possible to restore hearing by repairing the eardrum and reconstructing the ossicles. "
