Voice disorders range from changes in the quality of your voice to voice loss. You may be hoarse, feel like there’s something in your throat, or develop a vocal tremor. The specialists at Lakeshore Professional Voice Center, part of Lakeshore Ear, Nose & Throat Center in St. Clair Shores, Macomb Township, Rochester, Grosse Pointe, and Sterling Heights, Michigan, have extensive experience performing videostroboscopy, an advanced diagnostic technique that allows a complete analysis of your voice problem. If you experience voice problems, call or use online booking to schedule an appointment.
Videostroboscopy is an advanced imaging technique used to evaluate the characteristics and structure of your vocal cords. Videostroboscopy is the only way to assess the vibratory qualities of your vocal cords, which are essential for a normal voice, so it’s an essential tool for diagnosing and managing voice disorders.
Voice disorders are broadly defined as any change in voice quality, pitch, or volume that’s different from your typical voice, inappropriate for your age and gender, or that bothers you, even if your voice seems normal to others.
A few common causes of voice disorders include:
You can develop a voice disorder when physical changes occur in your vocal cords or larynx, when you have a nerve problem that affects the vocal mechanisms, or when you strain or fatigue your vocal cords.
To evaluate voice problems, your doctor must assess the vibratory ability of your vocal cords. They vibrate so quickly, however, that they’re impossible to examine. Videostroboscopy overcomes this problem by using a strobe light to illuminate the larynx.
During a videostroboscopy, your Lakeshore physician applies topical anesthesia then gently inserts a videostroboscopic unit into your throat. The unit consists of a narrow endoscope that contains a tiny stroboscopic light source, microphone, video camera, and video recorder. Your videostroboscopy is recorded so it can be reviewed and used to develop a proper treatment plan.
Vibrations produced by your vocal cords send a signal to a computer, which triggers the stroboscope to flash light at a rate slightly slower than your vocal cord vibrations. As a result, the vocal cords appear to move in slow motion.
Your doctor evaluates the vibratory qualities and structure of your vocal cords and larynx, including tissues lining the larynx and your vocal cord movements, to determine if they’re normal or show changes that impact your voice quality.
If you’re suffering from a voice disorder, videostroboscopy is an essential diagnostic tool to identify the cause and determine the best treatment. To schedule an evaluation, call Lakeshore Ear, Nose & Throat Center or book an appointment online today.
