[Videostroboscopy assessment in patients with vocal fold hypertrophy underwent microsurgery].
Chronic hypertrophic laryngitis concerns many people in our population. Their aetiopathogenesis is complicated and usually connected with exogenous harmful factors like occupational or environmental exposure. The basic aim of this research was to asses phonation function of the larynx after microsurgery on the basis of videostroboscopy examination. The second aim was to estimate the surgical treatment effectiveness depending on vocal fold hypertrophy extensiveness. The research was conducted on 50 subjects chosen from the population of patients with vocal fold hypertrophy treated at the Department of Laryngology Silesian Medical Academy in Zabrze from January to December 2003. All the examined patients underwent classical microsurgery. Videostroboscopy examination was done just before microsurgery and 3 months after operation. Examination results in two groups with different extensiveness of vocal fold hypertrophy were compared. The first group consist of patients with minor vocal fold lesions (limited to I of vocal fold length), the second group consist of patients with extensive vocal fold lesions (above I of vocal fold length). The control group presented 30 subjects without any voice disorders who did not use their voice for professional purposes. In both groups (with minor and extensive vocal fold lesions) significant improvement in videostroboscopy parameters was observed. The functional results in the group with minor vocal fold lesions were better after microsurgery, but it turned out that results were not statistically significant.
