Popis:	Objective(1) To determine glottic function following carbon dioxide (CO2) laser-assisted phonosurgery of benign laryngeal disease. (2) To evaluate post-operative glottic morphology and disease recurrence rate.MethodsComparative retrospective case series of patients with benign glottic pathology treated by laser-assisted phonosurgery over 10 years. 235 consecutive patients had pre- and postoperative data collected from objective laryngeal examination, videostroboscopy recording of vocal fold mucosal wave movement, electroacoustic voice analysis of fundamental frequency, jitter, shimmer, and harmonics to noise ratio, as well as perceptual voice evaluation. This data was also compared to that of 20 healthy volunteers. (Statistical analysis: Wilcoxon test and Mann-Whitney test respectively). Definitive voice and morphologic evaluation was completed after 6 months.ResultsEvaluation of the pre- and postoperative functional results demonstrated a statistically significant improvement in all spectrographically an...
