Health Information


  • Acoustic Neuroma

    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

    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

    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.

  • Audiology

    Audiologists address hearing and balance problems in people of all ages. They also help with the fitting and management of hearing aids.

  • Balance Disorders

    Detailed information on balance disorders, including acoustic neurinoma and Ménière's disease

  • Deviated Septum

    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 Disorders

    Detailed information on ear, nose, and throat disorders, including hearing disorders, balance disorders, smell disorders, taste disorders, chemosensory disorders, speech disorders, voice disorders, language disorders, vocal cord disorders, and laryngeal cancer.

  • 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

  • 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.

  • Fluency Disorder

    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).

  • Voice Disorders

    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.
