Abstract
Voice symptoms are frequently reported early after thyroidectomy, even in the absence of laryngeal nerves injury. We evaluated the short-term outcomes of these functional alterations. Thirty-nine patients were enrolled in a prospective observational trial, evaluating voice function before and 3 months after uncomplicated thyroidectomy, using VoiSS as assessed using a validated patient rated questionnaire; and perceptual voice analysis using GRBAS scale (Grade, Roughness, Breathiness, Asthenia, Strain). Impact of dysphonia on patient’s life using VoiSS questionnaire revealed differences between pre- and postoperative assessment. There was statistically significant worsening in the impairment subgroup of VoiSS (p = 0.027). GRBAS evaluation was consistent between the three independent raters but showed differences between pre- and postoperative voice assessment. Age, TSH and a preoperative finding of laryngopharyngeal reflux significantly predicted quality of voice after thyroid surgery (all p < 0.004), as identified by the GRBAS assessment tool, but not type of surgery, gender or smoking status; although prediction of total variance in changes of voice was modest (r 2 = 0.07). Voice changes may occur after thyroidectomy without evident laryngeal nerve injury. Patients should be made aware of possible mild changes in voice even after uncomplicated thyroid surgery and this might be considered to be part of the informed consent.
