Summary

Ultrasonic dissector (UAS) significantly reduces operative time and hospital costs in thyroidectomy compared to conventional technique (CT). However, UAS showed a higher incidence of transient laryngeal nerve palsy, with no difference in permanent complications.

The Thyroid Gland

The Thyroid Gland

The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Background:

Thyroidectomy is a common procedure for goitre and thyroid carcinoma.
Evaluating new surgical techniques is crucial for improving patient outcomes and cost-effectiveness.

Purpose of the Study:

To compare the benefits of ultrasonic dissector (UAS) versus conventional technique (CT) in thyroidectomy.
To assess operative time, complication rates, and hospitalization duration.

Main Methods:

A clinical controlled trial (CCT) involving 2,736 patients undergoing thyroidectomy.
Patients were divided into two groups: UAS (1,021 patients) and CT (1,715 patients).

Main Results:

UAS group had significantly shorter operative time (80 vs. 120 minutes).

UAS group showed a higher incidence of transient laryngeal nerve palsy (1.6% vs. 0.9%).

No significant differences were observed in permanent laryngeal nerve palsy, permanent hypocalcemia, or post-operative hospitalization (2 days).

Conclusions:

Ultrasonic dissector offers cost-effectiveness due to reduced operative time and hospitalization.
While UAS reduces operative duration, it does not improve outcomes regarding transient complications like laryngeal nerve palsy.
Surgeon experience remains the primary factor influencing complication rates in thyroidectomy.
