An adjustable supraglottiscope designed to be used in the supraglottic larynx is disclosed, in particular, an improved apparatus for endoscopic surgery in the supraglottis and the lower pharynx is disclosed by having at least one blade that is at least as wide as the normal, human epiglottis in its natural position within the body. The blades of the supraglottiscope have a length to width ratio that is about one-half of that found in conventional instruments. This unique ratio enables a wider exposure of the supraglottic larynx and lower pharynx. Methods of performing surgery on the supraglottic larynx of a patient are also described.
