Abstract

|
|
Background and Objectives : The aim of the present study is to evaluate the efficacy and usefulness of CO2 laser-assisted phonomicrosurgery using a computer-guided scanner (CGS) for treating broad-based vocal polyps.
Materials and Methods: Fourteen patients who underwent phonomicrosurgery for vocal polyp with broad base were enrolled for the study. The voice status of all the patients was evaluated by acoustic analysis, aerodynamic analysis, and voice handicap index before and after the operation, and the results were compared.
Results: All the voice analysis parameters were found to be normalized and improved after the operation compared with the preoperative status. In addition, all voice handicap index parameters improved after the operation.
Conclusion: The CO2 laser-assisted phonomicrosurgery using CGS makes it possible for surgeons to perform more accurate and delicate incision with a controllable depth of beam penetration.
