Otitis media can lead to dizziness. Otitis media is an inflammatory infection of the middle ear cavity caused by the invasion of bacteria or viruses, resulting in congestion, edema and exudation of the mucosa of the middle ear cavity, often secondary to an acute cold or flu. When the inflammation worsens, the virus and bacteria invade the skull, leading to meningitis and brain abscesses, which cause dizziness, headache, nausea and vomiting. The main symptom of otitis media is purulent discharge from the external ear canal, accompanied by hearing loss, tinnitus, dizziness and other related symptoms, which requires detailed examination of electronic otoscopy and mastoid CT at the hospital to confirm the diagnosis.
