Patients with eustachian tube obstruction often further lead to secretory otitis media. Patients usually need to use hormonal nasal spray drugs, or vasoconstrictor drugs, such as mometasone furoate nasal spray, fluticasone propionate nasal spray, hydroxymetazoline hydrochloride nasal spray, etc., which can help improve the inflammation, or allergy-induced inflammation, congestion, and swelling of the nasal mucosa, thus further improving the function of the eustachian tube and Improving the condition of negative pressure in the middle ear. If infectious and allergic factors are present in the nasal and sinus cavities, oral anti-infective and anti-allergic medications such as amoxicillin capsules, cefprozil tablets, loratadine tablets, etc. should be administered accordingly. If the patient has severe adenoid hypertrophy, further adenoidectomy may be required as appropriate.
