探讨假体凸度对假体隆乳患者术后胸围及罩杯的影响

To investigate the effect of prosthesis convexity on breast circumference and cup size of breast implant patients after surgery

目的探究假体凸度对假体隆乳患者术前术后胸围及罩杯变化的关系。方法回顾性分析自2020年01月至2021年01月在四川米兰柏羽医学美容医院行经腋路内窥镜辅助下假体隆乳术的348例患者,收集患者术前胸围、下皱襞围及罩杯数据,置入假体凸度信息,测量并收集患者术后即刻、术后2天,出院一个月、三个月、半年、一年胸围、下皱襞围及罩杯数据,通过数据分析不同假体凸度对患者术前术后胸围及罩杯的变化关系。结果患者胸围术前术后变化明显,差异有统计学意义(P<0.05),并在半年后逐渐稳定,无明显变化(PΔ(半年-一年)>0.05);下皱襞围术前术后变化无统计学差异(P<0.05);取患者术后半年胸围及下皱襞围数据分析,胸围及罩杯的变化趋势基本相同,311例(89.4%)患者选择假体凸度(d)与胸围变化(ΔCCN)及罩杯变化(ΔC)呈现出线性关系,表示为:ΔC/ΔCCN=2/3·2d,即术后胸围=术前胸围+2/3·2d,且发现该311例患者术前胸围均不超过A罩杯;同理,术前罩杯在(A,B]的有26例(7.5%),术后胸围较术前增加d;术前罩杯在(B,C]的有9例(2.6%),术后胸围较术前增加d4/5;术前罩杯在(C,D]的有2例(0.57%),术后胸围较术前增加d2/3。结论根据假体凸度可预测绝大部分假体隆乳术后患者的胸围及罩杯,为医生挑选假体,给患者制定个性化方案提供重要参考依据。

Objective To predict the relationship between the prosthesis convexity and the changes of breast circumference and cup in patients with breast augmentation.Methods A retrospective analysis of 348 patients who underwent axillary endoscopy-assisted prosthetic augmentation mammoplasty from January 2020 to January 2021 at the Bravou Plastic Surgery Hospital,,insert prosthesis convexity information,measure and collect the patient’s immediate postoperatively,2 days postoperatively,one month,three months,six months,one year of bust circumference,lower fold circumference and cup data after the patient’s discharge.Analyze the relationship between different prosthesis convexity on the patient’s chest circumference and cup before and after surgery.Results The patient’s chest circumference changed significantly before and after surgery,the difference was statistically significant(P<0.05),and gradually stabilized after half a year without significant change(PΔ(six months-one year)>0.05);the preoperative and postoperative changes of the lower fold circumference There was no statistical difference(P<0.05);the data of the chest circumference and lower fold circumference of the patients were analyzed for half a year after the operation.The changes of the bust circumference and the cup were basically the same.311 patients(89.4%)chose the prosthesis convexity(d)and the change of the bust circumference.(ΔCCN)and cup change(ΔC)showed a linear relationship,expressed as:ΔC/ΔCCN=2/3·2d,that is,postoperative bust=preoperative bust+2/3·2d,and it was found that the preoperative bust of the 311 patients did not exceed A cup;for the same reason,There were 26 cases(7.5%)whose preoperative cups were(A,B],and the postoperative bust circumference increased by d compared with that before operation;9 cases(2.6%)whose preoperative cups were(B,C],the postoperative bust circumference was higher than that before operation.d4/5 increased before operation;2 cases(0.57%)had cups in(C,D]before operation,and postoperative bust circumference increased by d2/3 compared with preoperative breast circumference.Conclusion According to the convexity of the prosthesis,the breast circumference and cup of most patients after breast augmentation can be predicted,so that doctors can choose the prosthesis and provide an important reference for the patient to formulate a personalized plan.
