In macromastia, especially in patients with a raised BMI, the nipple areola complex (NAC) may be displaced from the breast midline/meridian. This is poorly documented, and there is little published on surgical management. The aim of the study was to identify the incidence of displaced NAC in macromastia and discuss the management using the superomedial pedicle, by canting the vertical limbs of the inverted T/keyhole. The study also aimed to postulate a theory of pathogenesis.
The study is a retrospective review for a two-and-a-half year period. For study inclusion, the NAC had to be displaced 3 cm or more from the breast meridian. A superomedial pedicle was used with an inverted T pattern. The vertical limbs of the keyhole were canted medially for medially displaced NACs and laterally for laterally displaced NACs.
Fifteen patients were identified: three with medial and 12 with laterally displaced NAC. Mean age was 35 years (range 21-61) with a mean BMI of 31 (range 27-37). The mean mass of tissue excised was 1158 g (range 330-1969 g). The mean follow up is 7 months (range 2-21 months). One patient suffered partial areola loss, and 2 patients had a breakdown at the angle of sorrow/inverted T junction.
The displaced NAC is not uncommon in women with a raised BMI presenting for breast reduction. Canting the vertical limbs of the keyhole away from the deviated NAC yields satisfactory results in treating patients with a displaced NAC using a superomedial pedicle. A theory of possible pathogenesis is postulated; global attenuation of the breast footplate occurs, leading to lateral and inferior displacement of the NAC.
在巨乳症中,尤其是体重指数(BMI)升高的患者,乳头乳晕复合体(NAC)可能会偏离乳房中线/子午线。对此的记录很少,关于手术治疗的文献也很少。本研究的目的是确定巨乳症中NAC移位的发生率,并讨论使用上内侧蒂,通过倾斜倒T形/钥匙孔的垂直肢来进行治疗。该研究还旨在提出一种发病机制理论。
本研究是一项为期两年半的回顾性研究。纳入研究的条件是,NAC必须偏离乳房子午线3厘米或更多。采用上内侧蒂的倒T形术式。对于向内侧移位的NAC,钥匙孔的垂直肢向内侧倾斜;对于向外侧移位的NAC,则向外侧倾斜。
共确定了15例患者:3例NAC向内侧移位,12例向外侧移位。平均年龄为35岁(范围21 - 61岁),平均BMI为31(范围27 - 37)。切除组织的平均重量为1158克(范围330 - 1969克)。平均随访7个月(范围2 - 21个月)。1例患者乳晕部分缺失,2例患者在悲伤角/倒T形交界处出现裂开。
在因乳房缩小术就诊的BMI升高的女性中,NAC移位并不少见。使用上内侧蒂治疗NAC移位患者时,将钥匙孔的垂直肢向偏离的NAC倾斜可取得满意效果。提出了一种可能的发病机制理论;乳房底盘整体变薄,导致NAC向外侧和下方移位。
