RESUMEN
Background and Objectives@#Voice change after thyroidectomy is a common complication that affects a patient’s quality of life. In this study, we aimed to compare voice outcomes between minimally invasive open hemithyroidectomy (MIOT) and conventional hemithyroidectomy.Materials and Method We enrolled 215 patients who underwent hemithyroidectomy performed by an experienced surgeon at our institute between June 2017 and December 2021. All patients underwent voice evaluations, including subjective and objective assessments, preoperatively and 2 weeks and 2 months postoperatively. @*Results@#Sixty-one patients underwent MIOT (M group) and 154 patients underwent conventional hemithyroidectomy (C group). There were 50 female (82.0%) and 11 male (18.0%) in the M group, and 129 female (83.8%) and 25 male (16.2%) in the C group. In both groups, the thyroidectomy-related voice questionnaire score increased at 2 weeks and 2 months postoperatively. However, no statistically significant differences were observed between the two groups. Voice parameters were analyzed according to sex. There were some changes in the parameters in both groups. However, no statistically significant differences were observed between the two groups. @*Conclusion@#Our study showed no differences in the acoustic results between MIOT and conventional hemithyroidectomy.
