Abstract: Background and purpose: The endoscopic thyroidectomy using gasless postauricular crease and occipital hairline approach is rare in China. This study aimed to determine the clinical feasibility of this approach. Methods: Twelve patients who underwent endoscopic thyroidectomy and 12 patients who underwent neck surgery were analyzed from Feb. 2018 to Jan. 2019. The clinical features, surgical conditions, complications and cosmetic satisfaction between them were compared. Results: There was no significant difference in age, gender, tumor size, days of hospitalization, neck pain and the number of central lymph node dissection between the endoscopic group and the open group (P>0.05). The mean operating time of the endoscopic group［(88.1±13.8) min］ was longer than that of the open group［(60.4±9.4)min］, and the total amount of drainage［(134.2±62.0)mL］ of the endoscopic group was more than that of the open group ［(87.1±26.7)mL］ (P=0.024). The cosmetic satisfaction was superior in the endoscopic group (P<0.01). Conclusion: The endoscopic thyroidectomy using gasless postauricular crease and occipital hairline approach for thyroid cancer is safe, feasible, and cosmetic satisfying.
