Abstract: The invention relates to a laryngoscope with a light guiding portion for insertion into a patient's oral cavity and an observation device for diagnostics with visible light, comprising an illumination beam path for illuminating an examination area with a visible observation beam, and an imaging beam path for guiding the observation beam reflected from the examination area. Such known laryngoscopes permit diagnostics of pathological changes in deeper tissue layers. The laryngoscope of the invention enables this by means of an OCT device for diagnostics using optical coherence tomography, comprising an OCT illumination beam path for illuminating an examination area with the coherent beam, and an OCT imaging beam for guiding the coherent beam reflected from the examination area to an OCT module for generating an image of tissue layers in the examination area.
