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.
