Abstract:

Objective To investigate the efficacy of minimally invasive mamotone in the treatment of

benign breast tumors by comparing annular areola incision with traditional incision approach. Methods

A retrospective analysis was performed on 120 patients with benign breast tumors treated with minimally

invasive mamotone in Jiangmen Maternal and Child Health Hospital from January 2018 to December

2019. According to the surgical methods, they were divided into the traditional group and annular areola

group. In the traditional group, there were 60 cases, and there were 60 cases in annular areola group.

Data related to surgery were compared between the two groups, including operation time, blood loss and

one-time puncture success rate. The wound of 1 month and 3 month after surgery were compared. The

cosmetic effect of 3 months after surgery were compared. Results The operation time was significantly

longer in the annular areola group than in the traditional group (25.25±4.65 vs 20.25±3.56min,

P<0.01). The comparison of intraoperative blood loss, one-time puncture success rate and intraoperative pain score between the two groups was not statistically significant (P ＞ 0.05). Vancouver scar

scale(VSS) assessment in the annular areola group were significantly better than those in the traditional

group at 1 and 3 months after surgery (P ＜ 0.01). There was no statistically significant difference in

breast appearance score between the two groups in 3 months after surgery (P ＞ 0.05). Conclusion The

minimally invasive mamotone using annular areola incision can effectively improve the cosmetic effect

while ensuring the curative effect.
