These images and sounds were captured during video endoscopy examinations of patients at the Lions Voice Clinic. These are intended as examples and not definitive pictures of any type of voice disorder. Also because these are indirect views of the larynx, there may be picture artifacts relating to the angle of the camera in the throat or the color of the video screen.
Pictures r l Cysts - Growths that form underneath the
vocal fold mucosa. A cyst may form on one or both
vocal folds. Cysts causes a gap between the two
vocal folds and prevent normal vibration. The
resulting sound can range from normal to breathy to
very rough. r l Granuloma - A blister-like growth that
(in this case and most other cases) occurs in the
posterior (back) part of the larynx. This granuloma
has formed on one of the mucosal surfaces nearby
the vocal fold. The granuloma may prevent glottic
closure. Voice quality ranges from normal to
breathy to very rough. This particular granuloma is
considered rather large. r l Hyperkeratosis r l Leukoplakia r l Nodules - Soft, broad-based swellings at
the same location on both vocal folds (vocal
cords). These are considered to be early nodules.
As nodules mature, they typically become smaller,
more defined, harder and callous-like. r l Nodules - These nodules are smaller and
more well-defined. r l Papilloma r l Paralysis (unilateral) - In this picture
the left vocal fold does not move; it is paralyzed
near the midline. Seen in open position, the vocal
folds do not fully open. Because the left vocal
fold is paralyzed the arytenoid appears to "droop."
In a normal larynx, the left vocal fold would be
symmetrical with the right. r l Polyp - A fairly large polyp on the right
vocal fold. This polyp has a more watery texture,
and was removed surgically and treated with voice
therapy. The individual has a healthy voice. r l This polyp has a more solid texture. During
phonation and inhalation it moved above and below
the glottis as if on a hinge. Like the first
picture, this polyp was removed surgically. r l Reflux changes r l Varix - A blunt end of a varicose vein,
seen on the right vocal fold, possibly indicating a
former vocal fold hemorrhage. The varix may cause a
small specific area of stiffness on the vocal fold
(vocal cord) mucosa and may give a very slight
buzzy quality to the voice. Usually only noticed by
singers. r l Vocal Fold Bowing - Vocal folds don't
come together to vibrate. Instead, they leave a
gap, allowing air to leak through, usually
resulting in a weak, breathy voice. This picture
illustrates moderate bowing.
