Abstract
Recurrent respiratory papillomatosis (RRP) is a viral disease characterized by the growth of benign tumors on the vocal cords. Standard management of RRP currently consists of CO2 laser microsurgical ablation of the papillomas. Because of the recurrent nature of this disease, patients are often faced with significant cumulative risk of soft tissue complications such as vocal cord scarring. As a minimally traumatic alternative to management of RRP, we have investigated the use of the 585 nm pulsed dye laser (PDL) to cause regression of the papillomas by selective eradication of the tumor microvasculature. Three patients have been treated with the PDL at fluences of 6 J/cm2 (double pulses per irradiated site), 8 J/cm2 (single pulses), and 10 J/cm2 (single pulses), at noncritical areas within the larynx, using a specially designed micromanipulator. Lesions on the true cords were treated with the CO2 laser. Clinical examination showed that PDL treatment appeared to produce complete regression of papillomas. Unlike the sites of lesions treated by the CO2 laser, the epithelial surface at the PDL treatment sites was preserved intact. The presumed mechanism for papilloma regression following PDL treatment involves acute or chronic localized hypoxia caused by loss of tumor microvasculature.
