Long-term voice changes after thyroidectomy: Results from a validated survey.

Background: Long-term dysphonia may persist after thyroid surgery even in the absence of overt nerve injury. Therefore, we evaluated long-term dysphonia after thyroidectomy using a validated survey.

Methods: Patients undergoing thyroidectomy at a single institution from 1990 to 2018 were surveyed via telephone to complete the Voice Handicap Index-10 Survey.
