Background and Objectives Qualitative laryngoscopic investigations belong to diagnostic routine in laryngology. Nevertheless, quantitative morphometric measurements of intralaryngeal structures have been difficult by now. Study Design/Material and Methods The development of a two‐point‐light projection method for endolaryngeal measurements that works with a double reflecting mirror and green laser light is shown. Results The laser beams that have a distance of exactly 2 mm are very well visible at the surface of laryngeal structures. The technique can be used during a routine videoendoscopic examination. Conclusion In our opinion this method enables accurate quantitative morphological measurement within the larynx that could be used even in clinical routine. The two‐point light projection technique helps to reduce former limitations of endoscopic investigations. Lasers Surg. Med. 34:363–367, 2004. © 2004 Wiley‐Liss, Inc.
