目的 探讨与分析麦默通（Mammotome, MMT）乳腺微创旋切治疗乳腺良性肿瘤效果及对美观性的影响。方法 选取2019年8月—2022年1月收治的女性乳腺良性肿瘤患者110例作为研究对象,根据随机数字表法把患者分为麦默通组与对照组各55例。对照组给予传统乳腺肿瘤手术治疗,麦默通组给予麦默通乳腺微创旋切治疗,观察治疗效果与美观性变化情况。结果 所有患者都完成手术,术中无严重并发症发生,麦默通组的术后住院时间、术中出血量与对照组相比明显减少,手术时间对比差异无统计学意义（P>0.05）。麦默通组术后1个月的切口血肿、切口感染、静脉血栓等并发症发生率较对照组低,差异有统计学意义（P<0.05）。麦默通组术后1个月的乳房形状、乳头感觉、色素沉着等美容效果评分都明显高于对照组,差异有统计学意义（P<0.05）。结论 麦默通乳腺微创旋切治疗乳腺肿瘤能减少患者的术中出血量与术后住院时间,提高患者的美容效果,还可减少并发症的发生,降低患者的腋窝淋巴结转移率和远处转移率。

Objective To investigate the effects of Mammotome breast minimally invasive rotary resection on breast benign tumor and aesthetic appearence. Methods A total of 110 female patients with benign breast tumors admitted from August 2019 to January 2022 were selected as study subjects, and the patients were divided into the Mammotome group and the control group （55 cases each） according to the random number table method. The control group was given traditional breast tumor surgical treatment, and the Mammotome group was given Mammotome breast minimally invasive rotational treatment to observe the treatment effect and aesthetic changes. Results All patients completed the operation, and no serious complications occurred. The postoperative hospital stay and intraoperative blood loss in the Mammotome group were significantly reduced compared with the control group, and the difference in surgical time was not statistically significant （P>0.05）. The complication rates of incisional hematoma, incisional infection, and venous thrombosis at 1 month after surgery in the Mammotome group was lower than those in the control group （P<0.05）. The aesthetic effect scores such as breast shape, nipple sensation, and pigmentation at 1 month after surgery were higher in the Mammotome group than in the control group （P<0.05）. Conclusion Mammotome minimally invasive rotary resection can reduce the intraoperative bleeding and postoperative hospital stay, improve the beauty effects, reduce the occurrence of complications of patients with breast benign tumor, the rate of axillary lymph node metastasis and distant metastasis were decreased.
