Abstract:
OBJECTIVES:This study prospectively evaluated postthyroidectomy syndrome (PTS) through objective and subjective voice changes following thyroidectomy of open vs. endoscopic thyroidectomy. METHODS:A prospective clinical trial (SCHBC IRB 09 26) was performed from Jan 2008 to Aug 2010 to compare the open thyroidectomy (OPEN group) and endoscopic thyroidectomy (ENDO group). Of the 110 patients, 75 completed the evaluation before and 1 and 6 months after surgery. Subjective parameters included perceptual analysis (GRBAS [grade, roughness, breathiness, asthenia, and strain] scale), stroboscopic or flexible fiberscopic analysis, voice handicap index, and 5-point visual analog scales for vocal fatigue, singing difficulty, difficulty with high-pitch phonation, and neck discomfort. Objective parameters included acoustic, aerodynamic analysis and the electroglottograph. RESULTS:For the ENDO group (n=36), the operation time was longer than in the OPEN group (n=39; P<0.01). For the OPEN group, two objective and five subjective parameters were worse 1 month postoperatively; of these, two subjective parameters persisted for 6 months (P<0.05). For the ENDO group, three objective and six subjective parameters were worse 1 month postoperatively, and three of the subjective parameters persisted 6 months postoperatively (P<0.05). CONCLUSION:PTS really exists following simple thyroidectomy and are very common for both OPEN and ENDO groups. Most of the parameters improved gradually over time, but some subjective changes persisted 6 months postoperatively.
