Abstract:
Objectives: The purpose of the study was to determine the clinical-electrophysiological parameters of UVCP in relation to surgical methods. Methods: The survey was conducted between Jan 2017 and Jan 2021 on 82 adults with vocal cords paralysis, based on Phoniatrics Laboratory of FCHM. At the time of UVCP, one of the vocal cord injections and medialization surgeries was performed at the patient's requestand the sound quality was assessed by objective and subjective analysis before and postoperative 1, 6 months. Statistical analysis was performed using SPSS-20 software. Results: The fundamental frequency [injection (men: 161.2; women: 250.6 Hz); medialization (men: 165.8; women: 250.3 Hz)], maximum phonation time [injection (from 7.67 to 11.19 s); medialization (from 6.07 to 8.49 s)], harmonic noise ratio [injection (from 14.6 dB to 13.1 dB); medialization (from 15.21 to 14.17 dB), (p <0.05), improved statistically significant (p<0.05). Conclusions: Our research work has shown that medialization thyroplasty is more effective for glottal gap, vocal cord vibration amplitude are too lowand injection laryngoplasty more effective for harmonic-noice ratio and maximum phonation time are too low. Keywords: Unilateral vocal cord paralysis, Injection laryngoplasty, Medialization thyroplasty.
