Summary
A novel endoscopic technique uses parallel light beams for accurate morphometric measurement of laryngeal structures. This method simplifies assessing vocal fold lesions and vibration amplitudes during routine examinations.
Area of Science:
- Otolaryngology
- Medical Imaging
- Laryngology
Context:
- Accurate morphometric measurement of horizontal laryngeal structures is challenging in laryngology.
- Assessing vocal fold tissue lesion size and vibration amplitudes is difficult with rigid endoscopy.
Purpose:
- To introduce a new endoscopic technique for precise morphometric measurement of horizontal laryngeal structures.
- To overcome limitations of current rigid endoscopy in laryngology.
Summary:
- The method projects two parallel light beams onto the vocal folds during rigid 90-degree endoscopic examination.
- The fixed distance between light points enables accurate morphometric measurements, usable via video print post-examination.
Impact:
- This technique makes morphometric measurement of horizontal laryngeal structures feasible during routine laryngological examinations.
- It offers a practical solution for quantifying laryngeal anatomy and pathology.
