Acute suppurative otitis media is an acute suppurative inflammation of the middle - ear mucosa caused by bacterial infection. This disease is more common in children and frequently occurs in winter and spring. It often follows an upper respiratory tract infection.Clinically, it is characterized by earache, purulent discharge from the ear, and tympanic membrane perforation. If treated promptly and the secretions drain smoothly, the tympanic membrane perforation often heals on its own after the inflammation subsides, and most patients' hearing can return to normal. Improper treatment or severe illness may result in a persistent tympanic membrane perforation or the condition may turn into chronic suppurative otitis media, and even lead to various complications.Most patients experience severe pain before the tympanic membrane perforates, which is a throbbing or stabbing pain that can radiate to the same - side head or teeth. The earache eases after the tympanic membrane perforates and there is purulent discharge. There is also hearing loss and tinnitus.In the early stage of the disease, patients often have obvious ear fullness, tinnitus, and hearing loss.
