ABSTRACT
Background: CO
2 laser has been the laser of choice in laryngology for decades and has served as a reference for the development of new types of laser.
Objectives: To analyze the characteristics of CO
2 and other types of available lasers, as well as to demonstrate de usefulness of photoangiolytic lasers, specifically KTP, for microphonosurgery.
Material and methods: We reviewed medical literature searching for the otolaryngologic applications of the different types of available lasers, primarily in the field of laryngology. A comparative analysis was then conducted: between CO
2 and photoangiolytic lasers and between the two most commonly used photoangiolytic lasers: PDL
vs KTP. The practical use of these lasers was demonstrated with clinical cases.
Results: CO
2 laser has a high absorption affinity for water, for that it is highly effective for fine tissue cutting and bloc resections. Photoangiolytic lasers, specifically KTP laser, have a high absorption affinity for oxyhemoglobin, so they are a useful alternative for vascular and tumoral lesions that are in intimate contact with the delicate vocal fold epithelium.
Conclusions: Photoangiolytic lasers, specifically KTP, must be considered a useful alternative in vascularized laryngeal lesions. This particular type of laser offers great advantages over CO
2 laser, as lowering the risk of inadequate scarring as well as maintaining the integrity of vocal fold epithelium and superficial lamina propria (SLP).
