A videostroboscopy is an examination performed by an otolaryngologist to evaluate the function of the larynx while the patient is asked to repeat certain sounds by a speech language pathologist.
The short procedure uses a thin, flexible tube, about the size of a spaghetti noodle, called an endoscope. This instrument has both a camera and strobe light connected to a video monitor. First, a nurse will gently spray one nostril with an anesthestic to numb the area. The doctor will pass the endoscope through one nostril, through the back of the throat to look down on the voice box. The strobe light shines into the voice box so the motion of the vocal folds can be seen while speaking. This procedure helps the doctor and speech language pathologist to diagnose voice problems such as hoarseness or swallowing problems.
The procedure itself usually takes a few minutes. It is not painful. However your throat may be numb for a short period of time. Care should be taken when eating and drinking immediately after.
A bronchoscopy is a procedure that allows your doctor to look inside your lungs. It is performed in the surgery suite under a general anesthetic. It is performed with either a flexible tube or a rigid scope.
The flexible bronchoscopy has a light and small camera that is inserted into the nose or mouth. The tube is passed down the throat into the lungs. This is often used to see the upper airway structures as well as the lower airway.
A rigid bronchoscopy also has a light and small camera but is a rigid tube. It passes through the mouth and into the lungs.
Both bronchoscopies allow doctors to diagnose and treat various lung problems.
Vocal fold injection
Vocal fold injection, also called injection laryngoplast, is a treatment for vocal fold paralysis, paresis, atrophy, or scar tissue. It is performed in the surgery suite under a general anesthetic. While undergoing the procedure, a substance is injected into the vocal fold to increase bulk or mobility. This is a temporary fix which can be advantageous especially if the vocal fold nerve damage is temporary.
