Symptoms of chronic secretory otitis media include ear stuffiness, tinnitus, hearing loss, as well as insomnia, unresponsiveness, irritability and other ear and systemic symptoms. 1. Obstructed drainage of the Eustachian tube is the main cause of chronic secretory otitis media, which leads to accumulation of excessive secretions in the middle ear canal and the tympanic cavity, resulting in ear discomfort such as ear stuffiness, tinnitus, and hearing loss. 2. For chronic secretory otitis media with a long duration of illness, other symptoms such as slow reaction, insomnia, irritability, memory loss and sound orientation dysfunction may recur. Patients with chronic secretory otitis media should actively seek medical attention to clarify the cause and condition of the disease, and follow the doctor’s instructions for standardized treatment.
