Official Title: Is Superior Laryngeal Nerve Really Safe During Thyroidectomy Using Ultrasonic Dissector.
Brief Summary: New devices and techniques are coming into use everyday. Ultrasonic dissectors (UDs) are such new devices which is a practical alternative to the usage of scalpel and sutures. UD's cause overheating of neighboring tissues in an area of 1 to 3 millimeters. Due to the generated heat UDs might cause nerve injury. The investigators would like to see if usage of UDs during thyroidectomy poses a risk for superior laryngeal nerve injury compared to conventional thyroidectomy.
