Congenital breast deformities usually occur during adolescence and can disturb the self-development and affect the identity during this crucial stage. Several surgical techniques are now available to correct these different anomalies. The objective is to clarify the place of lipomodeling in thoraco-mammary malformations, resuming the different indications, the results, as well as the limits and potential complications. The adipose tissue was harvested by soft aspiration as to reduce adipocyte trauma and using a syringe fitted with a 3.5mm cannula. After centrifugation, fat was reinjected retrogradely and by making thin cylinders of fat similar to "spaghetti". Moderate to severe asymmetry is one of the best indications for lipomodeling using one or two sessions. Thus, a perfect and lasting symmetry is achieved, without the need of an implant, which would inevitably leads to asymmetry because of a dissimilar evolution of the breast all over the time. In Becker's nevus syndrome, lipomodeling has also been performant in bluring the hyperpigmentation of the nevus. The role of lipomodeling in pectus excavatum deformity (antero-posterior sternocostal depression) is also crucial. Lipomodeling can be used alone, or in combination with a rigid customed silicone implant. Tuberous breasts include various anomalies. Lipomodeling is currently used especially when the anomaly is unilateral (2 fat graft sessions are usually needed). Fasciotomies are frequently performed too. Lipomodeling is a real revolution in the management of Poland syndrome (anomaly characterized by the unilateral lack of the pectoralis major muscle, more or less associated with other ipsilateral anomalies). On average, 3 to 5 sessions are necessary to obtain a suitable symmetry. Lipomodeling is very unlikely to cause major surgical complications. Cytosteatonecrosis nodules mainly occur with novice practitioner and decrease as they become more experienced. However, the principle of the three-dimensional network, and the phenomenon of tissue saturation of the recipient site should be respected. The main limitation of lipomodeling is directly related to the amount of fat available. That's why it is very important to evaluate it during the first clinical consultation, and to carefully select the patients eligible in order to limit the risk of failure. Lipomodeling of congenital breast anomalies is a technique well established, with a precise algorithm to follow, and is a procedure with low surgical risk, less scarring, cosmetic and lasting results. This technique is to be suggested as a first line treatment in all indications of congenital breast deformities, alone or combined to an implant. Therefore, it seems essential that a plastic surgeon fully master the indications and the use of fat tissue transfer procedure, in order to obtain natural and harmonious results. |
