NCT01812395

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.

Outcome Measures

Primary Outcomes (1)

  • Assessment of superior laryngeal nerve function

    Patients will be checked for superior laryngeal nerve function by laryngostroboscopy one day after thyroidectomy and 6 months after thyroidectomy.

    6 months

Secondary Outcomes (2)

  • Assessment of inferior laryngeal nerve function

    6 months

  • Assessment of other complications

    1 week

Other Outcomes (1)

  • Assessment of hemorrhage

    3 day

Study Arms (2)

Ultrasonic Dissector Thyroidectomy

ACTIVE COMPARATOR

Thyroidectomy using harmonic focus (r) device

Device: Thyroidectomy using harmonic focus (r)

Classic thyroidectomy

ACTIVE COMPARATOR

Patients having conventional thyroidectomy

Procedure: Conventional thyroidectomy

Interventions

Harmonic focus(r) device is used to seal and cut the vessels during thyroidectomy.

Also known as: Ethicon(r) Harmonic Focus(r) Curved Shears
Ultrasonic Dissector Thyroidectomy

Vessels are ligated with sutures then cut using classic scalpel or scissors.

Classic thyroidectomy
