Causes of stuffy ears include cerumen impaction of the external auditory canal, secretory otitis media, sensorineural hearing loss, etc. Symptomatic treatment is needed according to the cause. 1. Cerumen embolism of the external auditory canal: For cerumen that is not completely blocked, it can be removed under otoscopy using tools such as cerumen hooks. If the cerumen is dry and hard, it should be softened with sodium bicarbonate first, and then removed by rinsing or suction. 2. Secretory otitis media: mainly due to the dysfunction of the Eustachian tube leading to pressure imbalance in the middle ear cavity, combined with decongestants such as ephedrine and hormonal sprays such as fluticasone propionate nasal spray are used alternately. In the chronic stage, Eustachian tube blowing can be promoted by using the Bowers ball method and other methods. Nasal endoscopy and other specialized examinations are needed to clarify the cause of nasal lesions. 3. Sensorineural hearing loss: Neural hearing loss will also cause ear stuffiness and blockage. It is necessary to combine with the hearing test results and give symptomatic treatment such as nutritional nerve, improving microcirculation, activating blood circulation and removing blood stasis. It is recommended that patients seek medical treatment in time and actively cooperate with doctors.
