Secretory otitis media is a non-suppurative inflammatory disease of the middle ear characterized by fluid accumulation in the middle ear and hearing loss, mostly seen in pediatric patients. The principles of treatment are comprehensive treatment such as removal of middle ear effusion, improvement of middle ear ventilation and drainage function, and etiological treatment. Patients with acute secretory otitis media can be treated with antibacterial drugs such as broad-spectrum penicillin, cephalosporins, macrolide antibiotics, etc. Oral glucocorticoids such as dexamethasone and bonisone can be used, but all of the above drugs are short-term treatment options. In case of nasal congestion, hydroxymetazoline hydrochloride decongestant can be used as nasal spray. Since some patients with secretory otitis media can heal spontaneously, for patients with mild symptoms, normal hearing and a short history of the disease, they can be closely observed and temporarily not operated. For those who are ineffective with the above treatments or those with more severe symptoms, surgical treatment, such as tympanocentesis, tympanotomy, and tube placement, is required. In addition, secretory otitis media can be caused by various factors such as dysplasia of the eustachian tube (pediatric adenoid hypertrophy, chronic sinusitis, nasopharyngeal carcinoma, dysplasia of the muscles surrounding the eustachian tube, eustachian tube cleaning and defense dysfunction), bacterial infection, and immune response (reactive rhinitis, nasal polyps, bronchial asthma). In addition to the above treatment, patients need to promptly identify the cause and treat the cause, such as removal of pediatric hypertrophied adenoids and removal of tonsils with recurrent inflammation. As mentioned above, secretory otitis media can be treated medically as well as surgically depending on the patient’s condition. Since secretory otitis media is one of the common causes of hearing loss in children, parents need to pay attention to it.
