N2 - INTRODUCTION: In clinical and scientific examinations with rigid and flexible endoscopes quantitative morphometric measurements of intralaryngeal structures have been difficult whereas qualitative laryngoscopic examinations are routine procedures. MATERIAL AND METHODS: The development of a two-point light projection method for endolaryngeal morphometry in its different phases is described. The way from a first prototype for endolaryngeal morphometry that works with a prism technique to the latest, most modern prototype, which works with a double reflecting mirror is shown. RESULTS: In combination with a newly developed PC software the latest prototype for two-point laser-light projection enables an accuracy of 95 % to 99 % in the measurement of intralaryngeal distances. The contrast of the laser beams to the mucous membrane of the larynx could be optimized by the use of green--instead of red--laser light. CONCLUSION: Morphological measurements within the larynx are now possible for clinical and scientific questions. Former limitations in quantitative morphometric examinations will be reduced.
