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. Copyright 2004 Wiley-Liss, Inc.
