Abstract
|
|
|
Background and Objectives: Our aim in this study is to evaluate the efficacy and usefulness of CO2 laser-assisted phonomicrosurgery using a computer-guided scanner (CGS) in benign vocal fold mucosal disorders.
Materials and Methods: The current study enrolled 93 patients who underwent phonomicrosurgeryfor benign vocal fold mucosal disorders. Twenty five patients underwent CO2 laser-assisted phonomicrosurgery using CGS (Group 1), and 68 patients underwent conventional phonomicrosurgery using a cold instrument (Group 2).
Results: All voice analysis parameters showed significant improvement after surgical treatment, except fundamental frequency. 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 allows for performance of more accurate and delicate incision with a controllable depth of beam penetration.
