There are two main clinical categories of deafness: I. Conductive deafness. Second, neurogenic deafness. Conductive deafness is mostly caused by inflammation, such as otitis externa, mastoiditis, otitis media, cholesteatoma, etc. The treatment is mostly anti-inflammatory and anti-infection treatment, and you can take cefradin capsules orally. At the same time, topical ear drops are used, such as oxyfloxacin ear drops. If the treatment is not effective, such as middle ear mastoiditis and cholesteatoma formation when conservative treatment is ineffective, surgery may be considered. If it is caused by neurogenic deafness, initially apply nerve-nourishing drugs, such as methylcobalamin tablets, ginkgo biloba, and vincristine capsules. If the treatment is not effective, hearing aids can be considered to improve the deafness symptoms.
