Laryngeal image biofeedback (LIB)

A technique first described to our knowledge by Dr. Bastian, in which videoendoscopy is performed and shown to the patient in real time, rather than being recorded and reviewed with the patient. The purpose of LIB is to allow the individual to modify his or her laryngeal behavior (and the vocal sound that results) using not only auditory and kinesthetic feedback, but also visual feedback.
