Common causes of pediatric tinnitus include neurogenic tinnitus, ear diseases, cerumen impaction, etc. Rare causes include improper use of medication, muscle spasms in the ear, etc. 1. Neurogenic tinnitus: it is more related to mental tension, late night, excessive study pressure, etc. It manifests itself as high-pitched tinnitus with intermittent attacks and normal intervals between attacks, so it should pay attention to self-pressure reduction, ensure sufficient sleep, and actively engage in physical exercise. 2. Ear diseases: e.g. tympanic membrane perforation, mostly secondary to acute otitis media, when the inflammation is severe, it can cause middle ear effusion, which triggers tympanic membrane perforation and leads to tinnitus, which requires tympanic membrane repair treatment. 3. Cerumen impaction: earwax or cerumen impaction in the external auditory canal, when cerumen or earwax close to the eardrum, it is easy to cause tinnitus, and should be removed in time. 4. Improper medication: Aminoglycosides, such as streptomycin and gentamicin, are ototoxic, leading to the destruction of the conduction structure in the ear, followed by hearing loss and triggering tinnitus. 5. Muscle spasm in the ear: stapedius muscle, periosteal distension muscle spasm, can cause myogenic tinnitus. In short, pediatric tinnitus, should be timely otolaryngology consultation, clear cause, take targeted treatment.
