ABSTRACT
Objective
The objective of this study was to compare phonetic outcomes of TOETVA with those
of conventional transcervical thyroidectomy(OPEN).
Methods
Retrospective chart review of total 61 patients who received thyroidectomy through
OPEN (n = 34) or TOETVA (n = 27) approach in single tertiary center were enrolled.
Results
There were significant differences in F0 between the two groups and there were significant
changes from different time points within each group in jitter for vowel /i/. Aerodynamically,
there were significant differences in mean sound pressure level for vowel /a/ and
mean sound pressure level, mean air pressure, and aerodynamic resistance for syllable
/pa/ between the two groups. In subjective VHI evaluations, there were no significant
differences between the two groups.
Conclusion
This study is significant in that it has investigated voices of patients with TOETVA.
Results of this study are expected to be useful for voice evaluation, treatment, and
prevention in the future.
