Video-assisted neck surgery for thyroid tumor: gasless lateral approach.

A 27-year-old woman with a thyroid tumor underwent right hemithyroidectomy to rule out malignancies such as follicular carcinoma of thyroid. A subplatysmal skin flap was dissected after making an incision in the anterior aspect of the neck, and the thyroid gland was exposed through the avascular space between the heads of the sternocleidomastoid muscle. After the insertion of the original retractor, video-assisted hemithyroidectomy was performed using ultrasonic surgical devices and conventional endoscopic forceps. Pathological examination of the resected specimen revealed follicular adenoma, and the postoperative course was uneventful. A lateral gasless approach for video-assisted thyroidectomy enables visualization of an adequate operative field and appears to be a safe and effective method.
