Curved laryngotelescope.
The purpose of this paper is to report on a newly developed curved laryngotelescope whose shape allows for smooth insertion through the oral and to the laryngeal cavity. Its principle of image processing involves lenses and prisms, which results in the maximum magnification of x6. Therefore, it is very useful for microscopic examination. We can obtain a clearer picture by this device than by conventional laryngoscopes. Examination with this laryngotelescope is easily performed after only topical application of a local anesthetic and patients experience less pain.
