Vocal Cords In Motion: More Accurate Diagnosis Of Voice Disorders Possible With Digital Videostroboscopy

CornerStone Ear, Nose & Throat recently became the only practice in Union County, and one of only two practices in Charlotte, to offer digital videostroboscopy. This diagnostic technique is available at the practice’s office at The Park in Monroe. Vocal cord vibrations are too fast to see with the naked eye. Videostroboscopy is a state-of-the-art technique that provides a magnified, slow motion view of the vocal cords in action. This makes it possible to detect subtle masses, scarring, and deficiencies in vibratory quality. Digital videostroboscopy also allows for evaluation of hyperfunction and straining that contributes to chronic hoarseness.

The Procedure

The procedure is performed on an outpatient basis at the Monroe office of CornerStone Ear, Nose & Throat, and takes about 30 minutes. A small monitoring device is placed on the patient’s neck to monitor voice pitch and intensity. A scope with a bright light and camera is placed in the patient’s mouth. As the patient vocalizes, the camera records and displays video of the vocal cords on a computer monitor. The physician conducting the test views the images during the exam and can play back segments of the video to educate patients about their condition. Two patient exams can even be loaded to compare side-by-side and assess a patient’s condition before and after therapy or surgery.

“It is an innovative and more accurate way to evaluate all patients with hoarseness and other vocal problems, especially those with symptoms that persist despite traditional medical management. It also produces a video recording that can be played back to the patients so they can better understand what is causing their problem.”

Vocal Fold Structure
The digital videostroboscopy system captures high-quality video through rigid and flexible endoscopes. Exams are monitored and recorded using a computer workstation that allows for immediate review and diagnosis.
