What’s going on with my voice? Videostroboscopy can help!

Is your voice not what it used to be?

Are you losing your voice frequently, experiencing hoarseness, or persistent strain?

Has an Ear, Nose, and Throat doctor (ENT) indicated that nothing is wrong with your vocal cords themselves?

A videostroboscopy assessment will provide a more detailed analysis of your vocal cords while you are producing sound and will help give you information on what is causing your voice issues so that changes can be made.

What Exactly is Videostroboscopy?

Videostroboscopy is a much more sensitive tool and more helpful in identifying subtle issues happening with the voice compared to other techniques, such as rigid or flexible transnasal laryngoscopy with continuous light sources (these tools are used through the nasal cavity). Videostroboscopy (through the mouth) provides a more detailed view than these other techniques and can reveal problems with the vocal cords such as growths, or irregularities in the vibration pattern or movement of the cords themselves.  Muscles surrounding the cords are viewed to see if they are working when voicing occurs.  The color of the cords and surrounding muscles is viewed to see if there is redness or swelling, and you can see if one cord is engaging more than another to make the voice work.  Videostroboscopy provides key elements in voice assessment to assist in a plan for voice recovery.

How Does Videostroboscopy Work?

Videostroboscopy uses a flashing light source to create a slow motion view of vocal cord vibration. Vocal cord vibration is very fast – the “slow motion” view is actually taken from many successive rounds of vibration. This unique viewing allows the voice care team to look at how each vocal cord vibrates during the different phases of the vocal cord’s vibration cycle, allowing for clear identification of smaller abnormalities in vocal cord movement that are unable to be observed using any other technique. From this information, therapy sessions to improve voice use can be prepared so that your intervention can be individualized and suited to your own specific needs.

Here is an example of a videostroboscopy analysis and how it looks when the vocal cords are viewed this way.

Who is a Candidate for Videostroboscopy?

Videostroboscopy is highly recommended when a voice disorder is due to abnormalities that affect vocal cord vibration. These abnormalities can include:

  • vocal cord scarring
  • a mass (cyst, polyp, nodule)
  • incomplete closure of the vocal cords
  • abnormal vocal cord vibration
  • asymmetrical/uneven movement of the vocal cords

What is a videostroboscopy and what is it used for?

Individuals suffering from voice problems will want to enlist the services of professionals that are trained in the use of videostroboscopy – the latest technology used in the assessment of voice disorders.

Voice impairments may include pain/strain when speaking, decreased vocal pitch range, hoarseness, or shortness of breath when talking. The cause of these problems is diagnosed by an Ear, Nose and Throat (ENT) doctor. The Speech-Language Pathologist can provide videostroboscopic analysis of the function of the vocal cords and subsequent treatment of the voice disorder.

Videostroboscopy creates a slow motion view of the vocal cords during phonation (voicing). Vocal cords normally vibrate at a very fast rate. Being able to see them in slow motion provides the detail to help identify any irregularities in the movement of the vocal cords.

The use of this assessment technology aids the Speech-Language Pathologist in planning vocal therapy and is beneficial for all types of vocal issues. It is a painless procedure and only takes a few moments to complete. S.L Hunter’s Voice Lab is fully equipped with the Videostroboscopy and Visipitch systems to ensure that we are able to provide a complete service to our community. If you have a voice disorder, S.L. Hunter & Associates can assist you in rehabilitating your voice in a safe and healthy manner.
