"It only occurs when your child has an active ear infection." Until the tubes fall out, your kid will most likely experience drainage anytime he or she develops an upper respiratory or ear infection. In most cases, this occurs between eight and fourteen months following surgery, according to him. "If you have any concerns about how your child is doing developmentally, it's important to discuss them with your pediatrician." Ears are a vital part of our body that play a role in hearing protection and balance. They can be affected by many different factors including disease, injury, and age. The ear consists of three main parts: the outer ear, the middle ear, and the inner ear. Your child's surgeon will be able to explain these parts further during your visit for post-operative care. The outer ear functions as a sound receptor by converting vibrations into electrical signals which reach the brain through the cranial nerve VII. The middle ear includes three bones (the malleus, incus, and stapes) that transmit sounds from the outside world to the inner ear where they are translated into impulses that control movement, balance, and eye position. The inner ear contains two chambers (the cochlea) that amplify small differences in pressure caused by sound waves reaching them from the middle ear. These pressure changes are then transmitted to the brain via the auditory nerve for interpretation.
