The preservation of the sensitivity of the nipple-areola complex after reduction mammaplasty is an important goal. The authors performed this prospective study to accurately assess whether sensitivity changes are influenced by the weight of resection or the surgical technique. Eighty patients who underwent bilateral breast reduction (Lassus, 10 patients; Lejour, 13 patients; McKissock, 18 patients; Wuringer, 20 patients; and Georgiade, 19 patients) were tested for sensitivity changes of the nipple and cardinal points of the areola with Semmes-Weinstein monofilaments before surgery, at 3 weeks, and at 3, 6, and 12 months after surgery. Patient characteristics (age, body mass index, and preoperative sensitivity) were statistically similar in all groups. The mean resection weight was significantly smaller in the Lassus (540 g) and the Lejour groups (390 g) than in the Georgiade group (935 g). The sensitivity of the nipple and the inferior and lateral part of the areola was significantly lower after a superior pedicle technique (Lassus and Lejour) than after any other technique at 3 weeks and at 3, 6, and 12 months postoperatively. Insensate nipples and areolas were found only after breast reductions with the Lassus and the Lejour techniques (47.8 percent). Nipple sensitivity after breast reduction by the other techniques was unchanged (Wuringer, McKissock, and Georgiade) or sometimes even improved (Georgiade) as early as 3 weeks postoperatively. Changes in nipple and areola sensitivity after reduction mammaplasty depend on the surgical technique rather than the weight of resection. Superior glandular pedicle techniques that require tissue resections at the base of the breast are associated with a higher risk of injury to the nerve branches innervating the nipple-areola complex.
乳房缩小成形术后保留乳头乳晕复合体的敏感性是一个重要目标。作者进行了这项前瞻性研究,以准确评估敏感性变化是否受切除重量或手术技术的影响。对80例行双侧乳房缩小术的患者(拉叙斯法10例;勒茹法13例;麦基索克法18例;武林格法20例;乔吉亚德法19例),在术前、术后3周以及术后3、6和12个月,使用Semmes-Weinstein单丝测试乳头及乳晕主要点的敏感性变化。所有组的患者特征(年龄、体重指数和术前敏感性)在统计学上相似。拉叙斯组(540 g)和勒茹组(390 g)的平均切除重量明显小于乔吉亚德组(935 g)。采用上蒂技术(拉叙斯法和勒茹法)后,乳头以及乳晕下外侧部分的敏感性在术后3周以及术后3、6和12个月时明显低于其他任何技术。仅在采用拉叙斯法和勒茹法进行乳房缩小术后发现乳头和乳晕感觉丧失(47.8%)。采用其他技术(武林格法、麦基索克法和乔吉亚德法)进行乳房缩小术后,乳头敏感性未改变(武林格法、麦基索克法),或早在术后3周时有时甚至有所改善(乔吉亚德法)。乳房缩小成形术后乳头和乳晕敏感性的变化取决于手术技术而非切除重量。需要在乳房基部进行组织切除的上腺体蒂技术与支配乳头乳晕复合体的神经分支损伤风险较高有关。
