The feeling that the ear is a bit blocked may be caused by cerumen embolism of the external auditory canal, secretory otitis media, chronic suppurative otitis media, etc. Cerumen should be removed, medication and surgery should be used to treat the disease. 1. Cerumen impaction of the external auditory canal: Cerumen should be removed with the help of a specialized doctor using tools such as cerumen hooks. If the cerumen is hard and dry, sodium bicarbonate drops can be applied to the ear to soften the cerumen and then suction out the cerumen with a suction device, or warm saline rinsing method to flush out the cerumen. 2. Secretory otitis media: In the acute infection stage, antibiotics such as amoxicillin, cefuroxime and roxithromycin can be used to control the infection in time. At the same time, dexamethasone and prednisone can be used for a short period of time to control the inflammatory reaction. If there are symptoms of nasal congestion, decongestants such as ephedrine can be used to improve the obstruction of the Eustachian tube. If necessary, tympanocentesis and fluid extraction, or tympanotomy and tube placement treatment. 3. Chronic suppurative otitis media: for those who have pus flow, clean up the pus in the external auditory canal and use ofloxacin ear drops to control ear inflammation.
