Does your child have frequent symptoms such as ear pain, ear congestion, and abnormal sounds in the ear after a cold, cough, or runny nose? Or if your child has been seen by a doctor and diagnosed with otitis media and it occurs frequently, more than 4-5 times a year, or several times a month or two; or if otitis media occurs and never fully heals and is delayed for several months; older children may complain of hearing loss. If any of these conditions occur, promptly visit an otolaryngologist for an examination. If the adenoids are abnormally enlarged and compress the airway between the nasal cavity and the middle ear (eustachian tube), it can lead to recurrent episodes of acute otitis media, which can lead to fluid accumulation in the middle ear tympanic cavity that cannot be absorbed, leading to adhesions in the glue ear and tympanic cavity over time, and finally causing hearing loss. At the same time, children with severe rhinitis can also affect the middle ear and need to be treated for rhinitis at the same time. We can examine the size and shape of the adenoids through fiberoptic nasopharyngoscopy, which is easy to perform, non-invasive, short in operation time, and can be done on an outpatient basis, with little pain for the child and intuitive and clear results. Because young children are often affected by their ability to express themselves verbally, resulting in masked ear symptoms, parents must pay attention to them or they will affect their child’s hearing.
