MULTIDIRECTIONAL OBSERVATIONS OF THE LARYNX USING TRANSURETHRAL RIGIDENDOSCOPES DURING DIRECT LARYNGOSCOPY

Microscopic direct laryngoscopy (microlaryngoscopy) under general anae sthesia is the optimal method of observing the larynx. However, as mic rolaryngoscopy does not allow precise observations of the ventricle, i nferior surface of the vocal fold and subglottis, multidirectional obs ervations of the larynx using transurethral rigid endoscopes were perf ormed during direct laryngoscopy. This endoscopic technique has been s hown to be clinically useful in the diagnosis and treatment of larynge al lesions. The equipment and methods are introduced herein, and a rep resentative case is presented.
