Endoscopic thyroidectomy developed rapidly in recent years, and the most popular surgical approach was endoscopic thyroidectomy by bilateral areola approach, but some operative steps was required optimization. One of the most annoying problem was the smog blurring endoscopic lens during surgery. The researcher summarized a set of convenient foot-control exhaust method and carried out this prospective study.
The patients with papillary thyroid microcarcinoma were included according to the inclusive criteria and randomly divided them into two groups (foot-control exhaust group and direct exhaust group). The foot-control exhaust group used the foot-control exhaust method by the way of adjustable Pressure to intermittent exhaust, while direct exhaust group exhaust through the Trocar hole. Comparison of operation time, times of wiping the endoscopic lens, volume of postoperative drainage, and number of identified parathyroid gland between two groups.
Exclusion criteria:
The foot-control exhaust group used of the Pressure adjustable foot-control method by the way of adjustable Pressure to intermittent exhaust
Device: used of the Pressure adjustable foot-control method
direct exhaust group exhaust through the Trocar hole.and without use of the Pressure adjustable foot-control method
Device: direct exhaust
Whether The Pressure adjustable foot-control method is used.
direct exhaust through the trocar.
Flap separation time
Flap separation time was acquired from endoscopic video was the period from endoscopy into the body to building up operation space.
Time frame: 1 day after surgery
Glandular excision time
Glandular excision time was defined from incising cervical white line to removing Berry ligament.
Time frame: 1 day after surgery
Central lymph node dissection time
Central lymph node dissection time: was from separating central lymph node to the specimen removed.

Times of wiping lens
Times of wiping lens calculated from endoscopic video after operation was defined the times of wiping lens from endoscopy into the body to central lymph node removed.
Time frame: 1 day after surgery
Volume of intraoperative blood loss
Volume of intraoperative blood loss was estimated the volume of intraoperative blood loss.
Time frame: 1 day after surgery

Volume of Postoperative drainage was accurately calculated the total volume while the drainage tube removed after operation.
Time frame: 1 day，2 day，3 day after surgery
The number of identifying parathyroid glands
The number of identifying parathyroid glands was evaluated at postoperation while parathyroid glands was identified during surgery.
Time frame: 1 day after surgery
