What is videolaryngostroboscopy?
A video laryngostroboscopy is used to help determine the cause of your voice disorder. An endoscope is inserted through your mouth toward the back of your throat and a stroboscope is passed through that. You will then be asked to complete a series of voice tasks.
Who introduced Laryngostroboscopy?
Laryngostroboscopy was introduced for the investigation of the vocal folds by Oertel in 1878 (11). Since that time laryngostroboscopy has brought a lot of valuable information on the mechanism of the vocal- fold vibration and successively became the indispensable standard clinical method for the examination of voice.
What is a strobe in ENT?
Video stroboscopy involves looking at the voice box (larynx) using a rapidly flashing light (strobe light) that, in effect, allows us to view the VOCAL CORDS moving in “slow motion”. In this way, the shape, vibration, and movement of the vocal cords in the voice box can be observed and recorded.
How does an ENT look down your throat?
Your doctor uses a small mirror and a light to look into your throat. The mirror is on a long handle, like the kind a dentist often uses, and it’s placed against the roof of your mouth. The doctor shines a light into your mouth to see the image in the mirror. It can be done in a doctor’s office in just 5 to 10 minutes.
Why laryngoscopy is done?
This test can be used to look for the causes of symptoms in the throat or voice box (such as trouble swallowing or breathing, voice changes, bad breath, or a cough or throat pain that won’t go away). Laryngoscopy can also be used to get a better look at an abnormal area seen on an imaging test (such as a CT scan).
Who performs a videostroboscopy?
Who performs the exam? Videostroboscopy may be performed by either an otolaryngologist (ear, nose, and throat doctor) or a speech-language pathologist.
Are you awake during a laryngoscopy?
You are awake for the procedure. Numbing medicine will be sprayed in your nose. This procedure typically takes less than 1 minute. Laryngoscopy using strobe light can also be done.
What is a videostroboscopy?
The videostroboscopy procedure is a state-of-the-art procedure that provides the doctor with a slow-motion, magnified view of your vocal cords in action. It enables a team approach where the doctor and a speech-language pathologist can evaluate a number of vocal parameters and view irregular motion and other conditions of the vocal folds.
What are the indications for videolaryngoscopy?
Indications. Videolaryngoscopy with stroboscopy is the essential diagnostic procedure for the evaluation of laryngeal mucosa, vocal fold motion biomechanics, and mucosal vibration. [7] These are the key elements for detecting and assessing pathology as well as determining the impact on voice and airway function.
What is the role of videolaryngoscopy in the evaluation of laryngeal mucosa?
Videolaryngoscopy with stroboscopy is the essential diagnostic procedure for the evaluation of laryngeal mucosa, vocal fold motion biomechanics, and mucosal vibration. [ 7] These are the key elements for detecting and assessing pathology as well as determining the impact on voice and airway function.
What is a stroboscopy of the larynx?
The stroboscopy provides the doctor with illumination of the larynx with fast light pulses, allowing for a detailed and accurate assessment of vocal cord motion. By looking at the images of the vocal cords and larynx, the doctor can obtain a better idea of how the vocal folds are functioning and come up with a tailored treatment plan.
