OBJECTIVETo explore the feasibility of endoscope-assisted thyroidectomy with minimal neck incision.

METHODSEndoscope-assisted thyroid surgeries had been accomplished through incision above sternal notch and in submental area respectively from August 2003 to August 2005, including 11 partial lobectomy, 3 lobectomy, 2 two-sides partial lobectomy, 1 isthmectomy.

RESULTSIn this group, 12 cases approached through above sternal notch, 5 cases approached through the submental area, and all were successful. The mean length of incisions was 2.3 cm (range from 1.5 cm to 3.0 cm). No one was converted to open surgery. The mean time of operation was 61.3 minutes (range from 30 minutes to 120 minutes). The mean volume of hemorrhage during the operation was 15.6 ml (range from 10 to 40 ml). The mean volume of drainage of post-operation was 22.5 ml (range from 6 ml to 40 ml). The mean length of stay was 4. 5 days (range from 3 days to 6 days). There were no hoarseness and no low serum calcium. Following visits were performed after operation from 1 month to 12 months, and there were no stiff feelings on skin. The cosmetic outcomes of the incisions were good, except 1 case for scar physique.

CONCLUSIONSEndoscope-assisted thyroidectomy was safe and feasible with good cosmetic outcome. The selection of approach with minimal incision depends on the location of neoplasm.
