title: Gasless endoscopic thyroid and parathyroid surgery using a new retractor.
abstract: Endoscopic thyroid and parathyroid surgery have now become feasible procedures, but the working space provided by the gasless technique is more limited than that of the CO2 insufflation technique. Gasless endoscopic surgery was performed in 20 patients with thyroid or parathyroid tumors. A newly designed retractor was used. Gasless endoscopic surgery was performed in all patients without conversion to conventional techniques. The recurrent laryngeal nerve was visualized and preserved in all patients. No recurrent nerve palsy was noted. The new retractor created a sufficient working space, and our results demonstrated the feasibility of this technique.
