The incidence of coincident abnormal laryngeal conditions is relatively high; therefore, voice screening before thyroidectomy is important. The "thyroidectomy-related voice questionnaire" is a simple and effective screening tool to detect preexisting laryngeal disorders that can affect the quality of voice.

During the early postoperative period, 28.3 % of patients had vocal cord palsy or lower-pitched voices, which could be evaluated using a simple questionnaire. Therefore, early postoperative voice evaluation is important. Patients with nonlaryngeal disorders may be more sensitive than those with laryngeal disorders to laryngeal symptoms.

Voice therapy may help to restore reversible mucosal change secondary to acidic reflux, inducing rapid resolution of symptoms and shortening of the treatment period.
