ABSTRACT
BACKGROUND AND OBJECTIVES: Previous studies have suggested the usefulness and importance of postoperative voice therapy, for which there are indirect and direct methods. The aim of this study was to evaluate the efficacy of treatment according to different voice therapy methods. SUBJECTS AND METHOD: Patients with vocal polyp were divided into three groups. Group 1 received direct voice therapy after phonomicrosurgery and Group 2 indirect voice therapy after phonomicrosurgery. Group 3 did not receive any voice therapy. RESULTS: Perceptual, acoustic, aerodynamic voice outcome parameters differed significantly between pre and post-operative treatments. In almost all of the voice analysis, Group 1, who underwent direct voice therapy, improved more significantly compared with Group 2 and 3. CONCLUSION: Postoperative voice therapy following phonomicrosurgery may be an effective adjuvant treatment in patients with vocal polyps. In particular, direct voice therapy can be effective for improving postoperative voice outcome.

Los pólipos de cuerda vocal son lesiones laríngeas benignas. Se asocian a micro-traumatismos por mal uso vocal que generan remodelación de la lámina propia y el epitelio. Es más frecuente en hombres entre los veinte y cuarenta años. En la gran mayoría de los casos se presenta de manera unilateral. Si bien estas lesiones están bien documentadas en la literatura, es raro encontrar presentaciones bilaterales, por lo que su enfrentamiento y manejo puede ser discutible. Se presenta el caso de una paciente de sexo femenino de 41 años, fumadora, que consulta por disfonía de larga data. Se diagnostican pólipos bilaterales de cuerda vocal, realizando una intervención quirúrgica en un tiempo, con un resultado favorable.
Vocal cord polyps are benign Iaryngeal lesions. They are associated to micro traumatisms because ofvocal misuse, generating a remodelation of the lamina propria and the epithelium. It is more common in men between twenty and forty years of age. In the vast majority of cases it unilaterally occurs. While these are well documented injuries in the literature, it is rare to find bilateral presentations, so their confrontation and management may be debatable. We present the case of a female patient, smoker, who consulted for chronic dysphonia. Bilateral vocal cord polyps were diagnosed, performing a bilateral resection with a positive outcome.

BACKGROUND AND OBJECTIVES: New computer-guided scanner (CGS) recently applied to CO2 laser micromanipulator allows the beam to sweep a given surface with extreme rapidity. Our aim in this study is to evaluate the efficacy and usefulness of CO2 laser-assisted phonomicrosurgery using a CGS in broad-based vocal polyp. SUBJECTS AND METHOD: The current study enrolled 41 patients who underwent phonomicrosurgery for broad base polyp of vocal fold. Twenty patients underwent CO2 laser-assisted phonomicrosurgery using CGS (Group 1), and 21 patients underwent conventional phonomicrosurgery using cold instruments (Group 2). RESULTS: All voice analysis parameters showed significant improvement after surgical treatment, except fundamental frequency and noise-to-harmonic ratio. Differences between preoperative and postoperative parameters of each voice analysis data did not differ significantly between the two groups. CONCLUSION: Although no significant difference was observed between the two groups, CO2 laser-assisted phonomicrosurgery using CGS allow for performance of more accurate and delicate incision with a controllable depth of beam penetration.
