Objective: To compare minimally invasive endoscopic thyroidectomy and traditional operation on their effects.Methods: 54 cases in aimed group accepted minimally invasive endoscopic partial thyroidectomy without air chamber;as a control

54 cases undergone traditional partial thyroidectomy.The compared indexes include bleeding volume in operation

hospitalization time

incision length

ache extent in incision

complications post-operation

and exterior inflammatory swelling on neck as well.Results: The bleeding volume in operation

hospitalization time and incision length in investigated group were markedly less than control(P<0.01).Moreover

there were no any serious complications post-operation such as dyspnoea

bleeding

hoarseness

broken voice

peri-mouse and extremities numbness

and/or extremities spasm and twitch.All patients in studied group recovered and have not recurred after 6-12 months’ follow-up.Conclusions: The clinical synthetic effect of minimally invasive endoscopic thyroidectomy is superior to traditional procedure obviously for its advantages of minimal invasion

beautiful incision

less complication and lighten ache.
