Abstract

Background and Objectives : Glottal area waveform(GAW) shows the plot of glottal area versus time through the 1 cycle. This study is designed to see how it can be applied to laryngeal patients. Material and Methods : A GAW analysis was peformed on 11 patients before and after surgery and 22 persons without laryngeal problems were recruited for control. Acoustic and aerodynamic analysis with VHI(voice handicap index) evaluation were performed. Results. Significant changes in baseline offset, gross closing rate and VHI were observed postoperatively. Other parameters were changed but insignificant. Conclusion : GAW maybe used to evaluate patient with voice problems.
