Background: 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.
Methods: 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.
Results: 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).
Conclusion: 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.
