New Audio & Video Exam of a Posterior Glottic Web Causing Noisy Breathing Posted!

A new video and audio examination of a patient with posterior glottic web after a traumatic and prolonged (2 week) intubation after a motor vehicle accident is posted. A posterior glottic web is a scar band that spans across the back aspect of one to the other vocal cord preventing it from opening fully. Such a restriction would restrict airflow resulting in "noisy" breathing as demonstrated in this sample.

Article in USA Today on Vocal Cord Dysfunction

I read this article in USA Today on vocal cord dysfunction and though this condition does exist, I do believe it is over-diagnosed. Another common cause of stridor with exercise is due to non-organic stridor where the vocal cords are so pliable, they vibrate even when they are widely apart, especially in young female athletes.

The key for diagnosis is to perform a fiberoptic laryngoscopy when symptommatic. Previous patients of mine know that I make them run laps around our office building until they start having symptoms at which time I will perform the exam. Here is more info on this particular topic.

New Video and Audio of True Vocal Cord Swelling in a Singer

A new audio and video strobe examination of a singer with true vocal cord swelling has been posted here. This example clearly demonstrates the hourglass gap with vocal cord adduction due to the swelling as well as onset delays and pitch breaks common in this particular disorder.

Vocal cord swelling is a very common and treatable cause of hoarseness in singers and in people who just plain like to talk a lot. It is considered the first stage before formation of nodules/polyps/cysts if not treated.
