| Abstract | Objectives: To analyze and correlate the voice related changes after and before thyroidectomy. According to studies, about 25- 90% of patients reported an abnormal voice within the few weeks after thyroidectomy. TVSQ is a self-administered screening tool to evaluate vocal status as well as throat and neck discomfort. Voice related changes in thyroidectomy patients were investigated using TVSQ and objective voice tool (PRAAT), as well as the correlations between TVSQ responses and Objective voice parameters.
Methods: Observational, longitudinal and quantitative study. A total of 15 (mean age of 54 years) patients including both male and female recruited in the present study those underwent thyroidectomy. Any laryngeal disorders other than laryngo-pharyngeal reflux on pre and post laryngoscopy were excluded from the study. Acoustic voice analysis using PRAAT and TVSQ responses were examined at different times: preoperative, 1 week and 1 month post-thyroidectomy. We then investigated the difference of acoustic characteristics between two groups’ i.e, pre and post-operative groups and analyzed the correlations between acoustic parameters and TVSQ responses.
Results: Out of all the acoustic characteristics, just the variations in the voice and TVSQ total scores were associated with jitter and shimmer worsening one month after surgery. Nevertheless, the connections were no longer statistically significant six months after the surgery. With the exception of the noise-to-harmonics ratio, all acoustic voice characteristics were significantly worse at one week after surgery and improved over time; however, the TVSQ score did not increase from its one week value until one month after surgery.
Conclusion: We discovered that the detrimental impact of lymph node status and dissection on vocal results following thyroidectomy may be captured by TVSQ. The TVSQ score was not statistically significantly connected with any other acoustic analysis parameters, despite a minor correlation between the deteriorated perturbation value and TVSQ changes.
