Buzzing in the ears is also clinically called tinnitus. In a quiet state, a normal person will hear a part of the tinnitus sound, which is very mild and usually does not affect the quality of life. However, if tinnitus occurs suddenly and is accompanied by hearing loss, the first step is to go to the ENT department for a simple ear examination, which requires both electrical audiometry and acoustic conduction resistance to rule out sudden deafness and otitis media. If the buzzing in the ear is neurological in nature, the first step is to nourish the nerves, improve microcirculation, and dilate blood vessels with medications, such as oral methylcobalamin tablets, ginkgo biloba, and vincristine capsules. If it is caused by inflammation, such as otitis media, anti-inflammatory treatment, together with the drug Cerno or Mucosolvan, nasal spray drug Cochlear.
