The lack of ear ventilation, or the feeling of stuffiness and congestion in the ear, needs to be treated according to the specific cause, which is commonly found in suppurative otitis media, boils in the external ear canal, cerumen embolism, etc. After the diagnosis is clear, follow the doctor’s instructions to choose general treatment, medication, surgery and other ways of treatment. 1. Suppurative otitis media: Inflammation will cause an increase in secretions, which will block the ear canal, resulting in a lack of air circulation in the ear. For treatment, 3% hydrogen peroxide can be used to clean the external ear canal and remove the accumulated secretion in the ear canal. Antibiotic ear drops, such as levofloxacin ear drops and lomefloxacin hydrochloride ear drops, can be chosen to control the infection. 2. Boils on the external auditory canal: Boils on the external auditory canal can also lead to a lack of air circulation in the ear. Treatment can follow the doctor’s instructions to use antibiotics, such as polymyxin B ointment, erythromycin ointment and other topical application. If there is abscess formation, incision and drainage treatment is feasible. 3. Cerumen embolism: If there is too much cerumen in the external ear canal, it can cause blockage of the ear canal, so the ear will be out of breath. For treatment, you can go to the hospital and let the professional doctor remove the cerumen through tools, i.e. ear canal foreign body removal surgery, so as to improve the symptoms. The lack of air in the ears can also be seen in the eustachian tube dysfunction, inner ear diseases, etc. After the symptoms appear, you need to go to the hospital in time to improve the examination, clear diagnosis, and then follow the doctor’s instructions to take standardized treatment, and the above medications should be used under the guidance of the doctor, do not do any random treatment, in order to avoid the adverse consequences.
