The most common cause of hearing loss in children is otitis media, the medical term for a middle ear infection or inflammation of the middle ear. This condition can occur in one or both ears and primarily affects children due to the shape of the young Eustachian tube. It is the most frequent diagnosis for children visiting a physician. When left undiagnosed and untreated, otitis media can lead to infection of the mastoid bone behind the ear, a ruptured ear drum, and hearing loss. If treated appropriately, hearing loss related to otitis media can be alleviated.
An infection of the outer ear structures caused when water gets trapped in the ear canal leading to a collection of trapped bacteria is known as swimmer’s ear or otitis externa. In this warm, moist environment, bacteria multiply causing irritation and infection of the ear canal. Although it typically occurs in swimmers, bathing or showering can also contribute to this common infection. In severe cases, the ear canal may swell shut leading to temporary hearing loss and making administration of medications difficult.
Earwax (also known as cerumen) is produced by special glands in the outer part of the ear canal and is designed to trap dust and dirt particles keeping them from reaching the eardrum. Usually the wax accumulates, dries, and then falls out of the ear on its own or is wiped away. One of the most common and easily treatable causes of hearing loss is accumulated earwax. Using cotton swabs or other small objects to remove earwax is not recommended as it pushes the earwax deeper into the ear, increasing buildup and affecting hearing. Excessive earwax can be a chronic condition best treated by a physician.
A cholesteatoma is a skin growth that occurs in the middle ear behind the eardrum. This condition usually results from poor eustachian tube function concurrent with middle ear infection (otitis media), but can also be present at birth. The condition is treatable, but can only be diagnosed by examination. Over time, untreated cholesteatoma can lead to bone erosion and spread of the ear infection to localized areas such as the inner ear and brain.
Ear tubes are tiny cylinders placed through the eardrum (tympanic membrane) to allow air into the middle ear. They also may be called tympanostomy tubes, myringotomy tubes, ventilation tubes, or PE (pressure equalization) tubes.
A perforated eardrum is a hole or rupture in the eardrum, a thin membrane that separates the ear canal and the middle ear. A perforated eardrum is often accompanied by decreased hearing and occasional discharge with pain. The amount of hearing loss experienced depends on the degree and location of perforation. Sometimes a perforated eardrum will heal spontaneously, other times surgery to repair the hole is necessary. Serious problems can occur if water or bacteria enter the middle ear through the hole.
