Fluid inside the ear is considered to be secretory otitis media. Secretory otitis media is mainly formed when the patient has a large amount of nasal mucus in the nasal cavity after a cold that has involved the middle ear cavity. Patients may feel a very serious feeling of stuffiness in their ears, and some patients may also have tinnitus, even accompanied by symptoms of hearing loss. If the patient has fluid in the ear, anti-inflammatory antibiotics can be applied, the more commonly used ones are cephalosporins. You can take oral eucalyptus pinene enteric soft capsules or Oronema drops to actively promote the discharge of fluid outward from the middle ear cavity, and you can also undergo physiotherapy baking treatment. If the patient’s condition does not improve significantly after half a month of active treatment, tympanocentesis or tympanic tube surgery can be considered, but often requires hospitalization under general anesthesia.
