目的探讨不同入路行双平面假体隆乳术的效果。方法回顾性分析2020年1月—2023年1月新乡市中心医院收治的629例行双平面假体隆乳术患者的临床资料,按其手术入路的不同将其分为2组,其中经乳晕入路行手术的329例患者纳入对照组,经腋窝入路...目的探讨不同入路行双平面假体隆乳术的效果。方法回顾性分析2020年1月—2023年1月新乡市中心医院收治的629例行双平面假体隆乳术患者的临床资料,按其手术入路的不同将其分为2组,其中经乳晕入路行手术的329例患者纳入对照组,经腋窝入路行手术的300例患者纳入观察组,术后均随访6个月。对比2组手术相关指标、乳房形态变化、隆胸效果、并发症。结果观察组切口愈合时间[(7.30±1.25)d]短于对照组[(9.21±1.69)d],并发症发生率(1.67%)低于对照组(4.86%),差异有统计学意义(P<0.05)。2组术中出血量、手术时间、住院时间、术后数字评分法(numeric rating scale,NRS)评分、隆胸效果相比,差异无统计学意义(P>0.05)。术前、术后2组乳头-乳房下皱襞的经皮距离(nipple to inframammaryfold,N-IMF)、胸骨切迹-乳头距离(sternal notch to nipple,S-N)、乳头-正中线距离(nipple to midline,N-M)、乳房总体积相比,差异无统计学意义(P>0.05)。结论经乳晕入路、经腋窝入路行双平面假体隆乳术均能够取得优良的隆胸效果,但经腋窝入路行手术更能够促进切口愈合,降低并发症发生率。文章的研究结果为临床后期选择双平面假体隆乳术的入路提供了借鉴内容,具有一定的运用价值。展开更多
