Microscopic direct laryngoscopy (microlaryngoscopy) under general anaesthesia is the optimal method of observing the larynx. However, as microlaryngoscopy does not allow precise observations of the ventricle, inferior surface of the vocal fold and subglottis, multidirectional observations of the larynx using transurethral rigid endoscopes were performed during direct laryngoscopy. This endoscopic technique has been shown to be clinically useful in the diagnosis and treatment of laryngeal lesions. The equipment and methods are introduced herein, and a representative care is presented.
