Voice and vocal self-assessment after thyroidectomy.

Background: Voice alterations after thyroidectomy can be found even with preserved function of laryngeal nerves. The purpose of this study was to evaluate voice before and after thyroid surgery and the role of orotracheal intubation on voice changes.

Methods: We conducted a prospective nonrandomized study of patients who underwent thyroid surgery and compared the results with a control group of patients who underwent breast surgery.
