Tinnitus and blockage in the right ear are generally considered to be caused by cerumen impaction in the right ear, secretory otitis media, and low-frequency deafness. 1. Cerumen impaction of the right ear: The right ear is buzzing and obviously blocked due to the blockage of cerumen in the external auditory canal. It is necessary to remove the cerumen with a cerumen hook, or apply 5% sodium bicarbonate drops to soften the cerumen, and then rinse it with warm saline or suction it out. 2. Secretory otitis media: Eustachian tube dysfunction caused by upper respiratory tract infections can lead to negative pressure or ooze in the middle ear, causing secretory otitis media, which generally requires nasal spray hormones, such as budesonide nasal spray, nasal decongestant, such as furosemide nasal drops, mucus promoters, such as eucalyptus-pin intestinal soft capsules, to promote the normal activity of the cilia. If necessary, perform tympanotomy or tube placement. 3 Low-frequency deafness: low-frequency deafness in the right ear is mostly considered to be caused by the labyrinthine effusion of the inner eardrum, which usually has buzzing in the right ear, and feels stuffy and blocked in the ear. Dietary salt restriction and glucocorticoids are usually needed to reduce the fluid in the inner ear. The buzzing in the right ear feels like a gas blockage, it is recommended to consult the hospital in time to clarify the diagnosis and treatment.
