A Novel Technique for Endoscopic Transaxillary Thyroidectomy Comparison

Study Overview
=================
Brief Summary
-----------------
The clinical data from all except the first 20 cases who underwent our novel transaxillary thyroidectomy were collected retrospectively, while the data from patients who underwent conventional open thyroid lobectomy by same surgeon during the same period were used as a control.
