Inframammary Flap Excision Method in Breast Augmentation: Improving Symmetry of NAC and IMF.

BACKGROUND

When we perform a breast augmentation through the inframammary fold (IMF) approach, incision placement at the new IMF is a key element of the planning process. In the majority of the previously published methods, the new IMF was planned based on the nipple-areola complex (NAC) position. However, these methods can lead to asymmetry in the IMF if the NAC is not symmetrical.

METHODS

We present the IMF flap excision method for correction of asymmetries of NAC and IMF. The new IMF position was marked based on the ICE technique. We have redesigned the higher side IMF to the same height as the lower side. And then we removed the amount of the skin and soft tissue, which corresponded to the difference between the 2 IMF. We dissected the submuscular breast pocket higher than in the usual cases, making it easier to move the breast tissue downward.

RESULTS

This method was performed on 21 patients, with an average follow-up time of 6 months (range, 2-9 months). The average correction amount of asymmetry of the NAC ranged from 3 to 15 mm and was maintained throughout the follow-up period. NAC downward positioning and symmetry of IMF were observed. Almost all patients showed improvement or complete resolution of their nipple asymmetry.

CONCLUSION

The IMF flap excision method corrected the asymmetries in the NAC and IMF without additional scars. This method should be strongly considered in patients undergoing a primary breast augmentation procedure with mild NAC asymmetry.
