When the ear sits and lies down, the main consideration is the accumulation of fluid in the middle ear cavity caused by secretory otitis media, or intracranial and extracranial vascular malformations and abnormalities, etc. If the patient has a respiratory infection, the nasal cavity and the ear canal are connected through the Eustachian tube. If the patient has a respiratory tract infection, acute and chronic rhinitis, etc. caused by a large amount of nasal secretion exudation, accumulation, due to the nasal cavity and the ear canal through the Eustachian tube to connect, the secretion can be retrograde infection caused by otitis media. In addition, we cannot rule out the existence of arterial diverticula, arterial malformations or arteriovenous fistulae that cause hemodynamic changes in the patient’s symptoms. When the patient appears more frequent and obvious ears sitting down nothing to lie down on the ringing of the situation, should promptly consult a doctor to clarify the diagnosis for targeted treatment.
