This study will assess the use of ultrasound-a test that uses sound waves to produce images-as a diagnostic tool for evaluating speech and swallowing.
The following categories of individuals may be eligible for this study: 1) healthy volunteers between 20 and 85 years old with normal speech and hearing, 2) patients 6 to 85 years old with developmental neurological deficits in speech or swallowing, and 3) patients with tumors of the oral cavity, pharynx or larynx being treated at the Greater Baltimore Medical Center.
Participants will undergo a 30-minute speech and oral motion evaluation, in which they imitate sounds, words and oral movements while a speech pathologist evaluates their lip, tongue and palate movements. They may also be asked to drink a small amount of water for examination of swallowing function.
For the ultrasound examination, a 3/4-inch transducer (device for transmitting and receiving sound waves) is placed under the participant's chin. While the transducer is in place, the subject 1) repeats sounds and a series of syllables in several sequences, 2) swallows three times with and without a small amount of water, and 3) swallows 3 teaspoons of non-fat pudding. The ultrasound images are recorded on tape for later analysis.
