If a patient is deaf in life, whether he or she can be fitted with a hearing aid depends on the nature of the deafness. If the deafness is caused by inflammation, there is no need to get a hearing aid. As long as active anti-inflammatory measures are taken to reduce swelling, the patient’s deafness will improve, for example, by using oxyfloxacin ear drops inside the ear and taking cefaclor capsules orally. However, in the case of neurological deafness, the onset of which has been a long time, especially in older patients who often affect communication with their families, the patient may consider wearing hearing aids. Hearing aid matching must go to the regular hospital, after testing hearing and trying on successfully, patients can choose, and they need to review hearing and debug hearing aids regularly so that patients can wear hearing aids with better effect.
