AIMS: The study aimed to assess voice quality in patients with bilateral abductor vocal cord paralysis (BAVCP) following transoral carbon dioxide (CO2) LASER posterior cordotomy with acoustic parameters. MATERIALS AND METHODS: Twenty-five participants were recruited over a three-year duration. Voice analysis was done twice, pre-operatively and three months post-operatively in decannulated patients, with the help of Praat software (Version 6.1.08) in a soundproof room, and subjective analysis was done using Voice Handicap Index (VHI 10) questionnaire pre-operatively and three months post-operatively. RESULTS: Of the total sample size of 25, the majority were females (60%). The mean age of participants was 32.16 ± 14.89. Among the 25 patients, 13 (52%) of them decannulated in the first attempt. Acoustic analysis revealed statistically significant decreases in fundamental frequency, intensity, shimmer, and maximum phonation time post-operatively ( CONCLUSION: CO2 LASER posterior transverse cordotomy is a safe option with reasonably good voice quality in patients with BAVCP for an adequate airway with minimal complications and a good success rate of decannulation.
