Abstract: Objective  To compare the effects of two different surgical methods in the treatment of female unilateral cT1N0-1a thyroid cancer and the satisfaction of incision cosmetics.Methods A retrospective analysis of the data of female patients with unilateral cT1N0-1a stage thyroid cancer in our hospital from October 2020 to September 2022 was conducted.They were divided into open group(65 cases) and oral group(55 cases) according to different surgical methods.Patients in open group were underwent traditional open thyroid surgery,and patients in oral group were underwent transoral vestibular approach laparoscopic thyroid surgery.Intraoperative conditions,postoperative complications and  satisfaction degree of postoperative incision beauty between the two groups were comparded.Results The operation time was (124.40±11.59)minutes and the dissection time of the central lymph node was (26.44±5.33)minutes in the transoral group,which were longer than those in the open group [(65.91±11.44)minutes and (17.38±4.32)minutes,(P<0.05)].Vancouver scar evaluation [(3.29±0.96)points],patient scar evaluation [(8.62±1.57)points],observer scar evaluation [(6.67±1.17)points] and scar self awareness score [(1.65±0.70)points] in the oral group were significantly lower than those in the open group [(5.29±1.20)points,(15.02±2.85)points,(19.57±2.94)points and (3.12±0.98)points,(P<0.05)].There were no significant difference in the amount of blood loss,the amount of drainage,the number of days in hospital and the number of central lymph nodes dissection between the two groups(P>0.05).There was no significant difference in  total incidence of postoperative complications(hoarseness,cough after drinking water,postoperative bleeding,subcutaneous effusion) between oral group and open group(7.2% vs 7.6%,P>0.05).Conclusion  The two surgical methods have their own advantages,the incidence of postoperative complications is low,safe and reliable,and the patients in the oral group are more satisfied with the cosmetology of the postoperative incision.In actual clinical work,the appropriate operation can be chosen according to the specific conditions of the patients.
