Cerumen blockage: children have more cerumen accumulation due to long time not pulling out the ear, cerumen close to the eardrum may cause tinnitus, cerumen should not be removed by themselves to prevent damage to the external ear canal. 2. Suppurative otitis media: most of the tympanic membrane perforation in children is secondary to acute infections, commonly suppurative otitis media, when the inflammation is more serious, it will invade the middle ear cavity and cause fluid accumulation in the middle ear cavity and perforation of the tympanic membrane, and then it will cause tinnitus. Tinnitus in children may also have other causes, it is recommended to go to the hospital in a timely manner, complete the examination to determine the cause of the disease, and then under the guidance of the doctor’s treatment.
