Ear Overview

An acoustic neuroma is a benign tumor of the cranial nerve that connects the inner ear and the brain. Though noncancerous and typically slow growing, it can affect both hearing and balance, and may cause hearing loss, tinnitus and dizziness. In rare cases, tumors may become large enough to press against the brain, interfering with…

Cholesteatoma is an abnormal skin growth in the middle ear behind the eardrum that may also affect the mastoid (skull bone). It begins as a cyst that gradually increases in size, destroying the bones of the middle ear and causing hearing loss.   What Causes Cholesteatoma?   When the Eustachian tube is functioning normally, it equalizes ear pressure…

Ear infections can occur in the outer or middle ear.  An ear infection occurs in the middle ear when fluid becomes trapped following a viral or bacterial infection. This painful affliction is most common in children, but can affect people of all ages. Infections can also occur in the outer ear.  They are most common when the skin in the…

If you’re a parent, it probably comes as no surprise that middle ear infections are common in children, particularly those between the ages of six months and two years. Known as otitis media, these are caused by a number of factors, both physical and environmental.   Most ear infections clear up on their own, or are treated with antibiotics. But in some children,…

What Causes Earaches?   Ear pain, commonly referred to as an earache, is a common complaint and can result from infection, poor Eustachian tube function, or temporomandibular joint problems (TMJ). Other causes include ear trauma, perforated eardrum, sinus infection, sudden changes in pressure, excess buildup of earwax, sore throat, shampoo or water in the ear, tooth infection, arthritis of the…

Earwax (cerumen) is a yellowish waxy substance produced by healthy ears. Earwax protects the ear from bacteria, water and foreign particles. It also assists in the cleaning and lubrication of the ear canal. Usually, excess wax is removed from the ear canal naturally. If a buildup does occur, the earwax will become hard and block…

In addition to pain and discomfort, a middle ear infection can cause tiny air cells in the mastoid bone to fill up with pus. As the infection spreads, potentially reaching the brain, the bone is destroyed, resulting in hearing loss. If antibiotics are unsuccessful in clearing up the infection, then mastoid surgery may be needed.  …

An eardrum perforation is defined as a hole or rupture in the eardrum. Known medically as a tympanic membrane rupture, this tear occurs in the membrane separating your outer ear from your inner ear. A perforation can lead to a middle ear infection and possible hearing loss, though in many cases it will heal on its own without medical treatment.   The…

What Causes Ear Infections? Ear infections occur when fluid fills the space between the eardrum and the inner ear. This happens when the Eustachian tube becomes blocked thanks to a virus or bacterium, preventing mucus and pus from draining out of the middle ear. These fluids put pressure on the eardrum, causing pain and discomfort.…
