Symmetrical height of the nipple-areola complex (NAC) is a key factor in the perception of breast symmetry. For preoperative markings, we mainly rely on conventional anthropometric measurements of distances in correlation to anatomical landmarks. In this study, we evaluated whether the use of a class 2 laser projection water level would lead to better symmetry of nipple height in reduction mammoplasty procedures when used for preoperative planning.
We analysed 100 patients undergoing reduction mammoplasty with a supero-medial pedicle and wise-pattern skin resection. We compared the bilateral differences in nipple height of the last 50 reduction mammoplasty procedures before using the laser projection water level (group A; no laser) with the first 50 reduction mammoplasties after implementation of this device (group B; laser). The follow-up period was 12 months.
A total of 48 patients were included in group A and 44 patients in group B. Patient demographics, mean resection weight and complications did not differ statistically significantly. Nipple height differences were significantly lower in group B (laser), measuring 0.22 ± 0.20 cm (0-0.9; n = 44), than those in group A (no laser; p < 0.001), measuring 0.61 ± 0.28 cm (0.2-1.2; n = 49).
Using laser level projection helped improve nipple height symmetry in reduction mammoplasty. We consider a difference of more than 1 cm in nipple height to be unacceptable in aesthetic reduction mammoplasty. This simple tool facilitates preoperative markings, and we find it to be safe, quick to install and very helpful in daily practice.
乳头乳晕复合体（NAC）的对称高度是影响乳房对称性的关键因素。在术前标记时，我们主要依靠与解剖标志相关的常规人体测量距离。在本研究中，我们评估了在乳房缩小整形手术的术前规划中使用2类激光投影水平仪是否能使乳头高度更对称。
我们分析了100例行上内侧蒂和 Wise 模式皮肤切除的乳房缩小整形手术患者。我们比较了在使用激光投影水平仪之前的最后50例乳房缩小整形手术（A组；未使用激光）与使用该设备后的前50例乳房缩小整形手术（B组；使用激光）的双侧乳头高度差异。随访期为12个月。
A组共纳入48例患者，B组纳入44例患者。患者人口统计学、平均切除重量和并发症在统计学上无显著差异。B组（使用激光）的乳头高度差异显著低于A组（未使用激光），B组为0.22±0.20厘米（0 - 0.9；n = 44），A组为0.61±0.28厘米（0.2 - 1.2；n = 49）（p < 0.001）。
在乳房缩小整形术中使用激光水平投影有助于提高乳头高度对称性。我们认为在美容性乳房缩小整形术中乳头高度差异超过1厘米是不可接受的。这个简单的工具便于术前标记，我们发现它安全、安装快速且在日常实践中非常有用。
