The stuffiness in the ear can be either conductive or sensorineural, and an endoscopic examination should be perfected. Firstly, if there is significant cerumen in the external ear canal, the symptoms can usually be relieved quickly after removal. Secondly, if there is inflammatory infection causing swelling and narrowing of the external ear canal, antimicrobial agents and, if necessary, glucocorticoids are required as appropriate. Symptoms are usually relieved quickly after the infection is controlled. Again if the endoscopic examination of the ear reveals significant fluid accumulation in the eardrum, it can be a secretory otitis media. Antimicrobial agents, mucus promoters, and short-term nasal vasoconstrictors are needed. For medication that does not work, tympanic tube placement or dissection can be done. Endoscopic examination of the ear does not reveal any abnormality. Early improvement of the hearing examination is required, mainly to rule out sensorineural sudden deafness. Once the disease is confirmed, early treatment with medications, mainly glucocorticoids to regulate the autonomic nerves and improve inner ear circulation, is indicated. The earlier the treatment, the higher the chance of recovery.
