Summary
Postthyroidectomy syndrome (PTS) affects voice quality after both open and endoscopic thyroidectomy. While most voice changes improve over time, some subjective issues persist for at least six months.
Area of Science:
- Otolaryngology
- Surgical Innovation
- Voice Science
Background:
- Postthyroidectomy syndrome (PTS) encompasses voice and swallowing disturbances after thyroid surgery.
- Objective and subjective voice changes are common sequelae of thyroidectomy.
- Comparing open thyroidectomy (OPEN) and endoscopic thyroidectomy (ENDO) is crucial for understanding PTS outcomes.
Purpose of the Study:
- To prospectively evaluate postthyroidectomy syndrome (PTS) by assessing objective and subjective voice changes.
- To compare voice outcomes between open thyroidectomy and endoscopic thyroidectomy.
- To determine the persistence of voice alterations at 1 and 6 months post-surgery.
Main Methods:
- A prospective clinical trial involving 110 patients undergoing thyroidectomy (75 completed follow-up).
- Comparison between open thyroidectomy (OPEN) and endoscopic thyroidectomy (ENDO) groups.
- Assessment of subjective parameters (GRBAS scale, Voice Handicap Index, vocal fatigue, singing difficulty, phonation, neck discomfort) and objective parameters (acoustic, aerodynamic, electroglottography).
Main Results:
- Endoscopic thyroidectomy had a longer operative time than open thyroidectomy.
- In the OPEN group, 2 objective and 5 subjective voice parameters were worse at 1 month, with 2 subjective parameters persisting at 6 months.
- In the ENDO group, 3 objective and 6 subjective voice parameters were worse at 1 month, with 3 subjective parameters persisting at 6 months.
Conclusions:
- Postthyroidectomy syndrome (PTS) is a common occurrence following both open and endoscopic thyroidectomy.
- While most voice parameters show gradual improvement, certain subjective voice changes can persist for up to 6 months post-surgery.
- Both surgical approaches result in PTS, highlighting the need for vocal rehabilitation strategies.
