Initially the diode laser in the otolaryngological field was not very highly valued in its first version with sources that did not exceed 800 nm, produced more heat and were less hemostatic. With the recent advent of wavelengths above 900 nm with specific selectivity on haemoglobin and water, excellent vaporization and high precision cutting/coagulation is ensured.
In ENT, the laser beam is transmitted on the surgical field in two ways depending on the type of application:
- NO CONTACT, with photothermolytic selectivity on the hyperchromic tissues preserving the surrounding healthy tissue
- CONTACT, through flexible optical fibers with a size between 200 and 600 microns. This feature can also be used in an endoscopic environment, regardless of the type of endoscope used.
