Acoustic neuroma is a rare non-cancerous tumor. It grows slowly from an overproduction of Schwann cells. The tumor then presses on the hearing and balance nerves in the inner ear. Schwann cells normally wrap around and support nerve fibers. A large tumor can press on the facial nerve or brain structures.
Hearing aids are electronic or battery-operated devices that can amplify and change sound. A microphone receives the sound and converts it into sound waves. The sound waves are then converted into electrical signals.
Aphasia is a language disorder caused by damage in a specific area of the brain that controls language expression and comprehension. Aphasia leaves a person unable to communicate effectively with others.
Audiologists address hearing and balance problems in people of all ages. They also help with the fitting and management of hearing aids.

A wall of cartilage divides the nose into two separate chambers. It’s called the nasal septum. A deviated septum is when this wall is shifted away from the midline. This may cause congestion, problems with breathing, or nasal discharge.
Hearing and Speech Communication Services and Devices
In addition to hearing aids, many other devices are available to help improve communication in daily life. These range from telephone amplifiers to visual alarm systems.

Ear, Nose, and Throat Facts
The ear consists of three areas—the outer, middle, and inner ear. The nose is the organ of smell and is part of the peripheral nervous system. The throat is a ring-like muscular tube that acts as the passageway for air, food, and liquid.

In some people, hearing loss can be surgically corrected. For others, medical devices and rehabilitation therapies often can help reduce hearing loss.

Ménière's disease is a balance disorder. It’s caused by an abnormality in part the inner ear called the labyrinth. Fluid build-up here can cause severe spinning sensation (vertigo) and affect the hearing.
- Noise-Induced Hearing Loss in Children
Your child’s inner ears may be damaged if he or she is around extremely loud noises or around loud noises for long periods of time. This is called noise-induced hearing loss.

Middle Ear Infection
Otitis media is infection or inflammation in the middle ear. Most kids have at least one ear infection by the time they are 3 years old. But, adults can also get ear infections.
Otolaryngology is the medical specialty that focuses on medical and surgical treatment for patients who have disorders of the ear, nose, throat, and related structures.
Presbycusis is the gradual loss of hearing that occurs as people age. One in three older adults older than 60 has hearing loss. Half of people older than 75 have hearing loss.
Sinusitis is an infection of lining of the sinuses near the nose. These infections most often happen after a cold or after an allergy flare-up.

- Smell and Taste Disorders
Smell and taste disorders may include loss of smell or taste or reducted ability to smell or taste. It can be caused by certain underlying conditions or illness, medications, and dental problems. Some people are born with these disorders.
Spasmodic dysphonia is a voice disorder. It causes involuntary spasms in the muscles of the voice box or larynx. This causes the voice to break, and have a tight, strained, or strangled sound.

Tinnitus is the sound of ringing, roaring, buzzing, hissing, or clicking that occurs inside the head. The sounds may come and go, be continuous, occur in one or both ears, and vary in pitch.
Tonsillitis means that your tonsils are inflamed. Your tonsils are large, fleshy glands at the back of your throat. These glands make antibodies that help fight infection.

- Usher Syndrome in Children
Usher syndrome is a disorder that is passed down through families (inherited). A syndrome is a group of symptoms that happen together. Usher syndrome involves both hearing loss and vision loss. The hearing loss may be mild to complete.
- Vocal Cord Disorders
The vocal cords (also called vocal folds) are two bands of smooth muscle tissue found in the larynx (voice box). The larynx is set in the neck at the top of the trachea (windpipe). The vocal cords vibrate and air passes through the cords from the lungs to produce the sound of your voice. The sound is then sent through the throat, nose, and mouth, giving the sound "resonance." The sound of each person's voice is determined by the size and shape of the vocal cords and the size and shape of the throat, nose, and mouth. Vocal cord disorders affect the vocal cords.
- Stuttering in Children
Stuttering is a speech problem. The normal flow of speech is disrupted. A child who stutters repeats or prolongs sounds, syllables, or words. Stuttering is different from repeating words when learning to speak. Stuttering may make it difficult for a child to communicate with others.
Otitis Media (Middle-Ear Infection) in Adults
A middle-ear infection is an infection behind your eardrum. This kind of ear infection can happen after any condition that keeps fluid from draining from the middle ear. These conditions include allergies, a cold, a sore throat, or a respiratory infection.
Vestibular Balance Disorder
Dizziness and vertigo are classic symptoms of a vestibular balance disorder. Balance disorders can strike at any age, but are most common as people age.
A person with fluency disorder has trouble speaking in a fluid or flowing way. They may repeat parts of words (stutter) or speak fast and jam words together (clutter).
A voice disorder is when a person has a problem with pitch, volume, tone, and other qualities of this or her voice. These problems occur when the vocal cords don't vibrate normally.
