Gasless endoscopic surgery was applied to a thyroidectomy. Compared with th
e previous method of endoscopic thyroidectomy, this method is superior in o
btaining hemostasis and minimizing the possible complications of gas-insuff
lating surgery, such as a hypercapnia or massive subcutaneous emphysema. We
successfully removed 37 thyroid tumors in 35 patients by gasless endoscopi
c surgery without any significant complications. No scars remained in the n
eck, and all patients were satisfied with the cosmetic results. Gasless end
oscopic thyroidectomy is a safe and technically feasible alternative to con
ventional thyroidectomy for cases of benign thyroid tumors and has good cos
metic results.
