Patients with otitis media need to see an otolaryngologist. Otitis media is a common disease in otolaryngology, mostly caused by pneumococcus, Haemophilus influenzae, and Streptococcus haemolyticus. Acute suppurative otitis media occurs in children, and the germs can invade the middle ear through the eustachian tube route. When the tympanic membrane is ruptured and perforated, external germs can enter the middle ear through the external ear canal and become inflamed. In clinical practice, the main symptoms of otitis media are ear pain, a feeling of stuffiness and swelling, and hearing loss in severe cases. Patients can have pure tone audiometry and also acoustic conduction resistance.
