Objectives. The objective of this study was to develop a new device that provides a simple, noninvasive method of measuring accurate lesion size while using an endoscope.
Methods. We developed a rigid laryngoscope with a built-in laser-ruler using a one-light emitting diode and an acrylic plate.
The invention incorporates a built-in laser diode that projects an auto-parallel beam into the optical path of the rigid laryngoscope to form two spots in the field of view.
Results. While the interspot distance remains consistent despite changes in focal plane, magnification, or viewing angle of the laryngoscope, projection to an uneven surface introduces certain variations in the shape, and size of the spots,and the distance between the two spots.
Conclusion. The device enables a laryngologist to easily measure the distance between landmarks, as well as the change in real size, and the progressive change of vocal fold lesions in an outpatient setting.
