Abstract

Laryngeal lesions such as papilloma, precancerous dysplasia, and vascular malformations can significantly impact voice production and patients’ quality of life. These nonmalignant conditions of the larynx can disrupt glottic closure patterns and inhibit propagation of the mucosal wave during phonation. Surgical techniques for the management of these lesions have advanced exponentially with further understanding of the importance of preserving the superficial lamina propria (SLP) layer and advances in surgical technology. Laser applications for nonmalignant conditions of the larynx have allowed for lesions such as papilloma and precancerous dysplasia to be optimally treated with maximum preservation of the underlying layered vocal fold microstructure. Photoangiolytic lasers such as the 585 nm pulsed-dye laser (PDL) and 532 nm KTP laser specifically target the microvasculature associated with the growth of these nonmalignant lesions and offer a fiber-based delivery system that allows for office-based surgery using topical anesthesia. In general, the primary advantages of laser surgery for nonmalignant conditions of the larynx are extreme precision, hemostasis, and selectivity for certain tissue “targets” such as blood vessels, without harming surrounding tissue. Also, a 2013 nm diode-pumped thulium laser has been introduced into endoscopic laryngeal surgery for the treatment of certain benign conditions. This laser—s chromophore is water, allowing for properties of hemostatic cutting on a fiber-based delivery system. This chapter will highlight salient principles of angiolytic laser use in the surgical management of vocal fold papilloma, precancerous dysplasia, and microvascular malformations both in the operating room under general anesthesia and in office-based settings with topical anesthesia. Additionally, office-based and microlaryngeal applications of the thulium laser in performing endolaryngeal surgery for benign conditions are reviewed.
