Summary
A new two-point light projection technique allows for accurate quantitative morphometric measurements of intralaryngeal structures during routine laryngoscopy, overcoming previous endoscopic limitations.
Area of Science:
- Otolaryngology
- Medical Imaging
- Biomedical Engineering
Background:
- Qualitative laryngoscopy is standard in laryngology.
- Quantitative morphometric measurements of intralaryngeal structures remain challenging.
Purpose of the Study:
- To present a novel method for quantitative endolaryngeal measurements.
- To overcome limitations of current endoscopic investigations.
Main Methods:
- Development of a two-point light projection system.
- Utilizes a double reflecting mirror and green laser light.
- Integrated into routine videoendoscopic examinations.
Main Results:
- Laser beams (2 mm apart) are clearly visible on laryngeal structures.
- The technique is feasible during standard videoendoscopy.
Conclusions:
- The two-point light projection method enables accurate quantitative laryngeal morphometry.
- This technique can be implemented in clinical routine.
- It addresses previous limitations in endoscopic laryngeal investigations.
