The Use of Acellular Dermal Matrix in Breast Mastopexy and Augmentation
Goals/Purpose:
Women who underwent periareolar mastopexy and augmentation tend to develop widening of the nipple areolar complexes (NAC). The enlargement of the NAC is likely due to gravity and/or implant exerting radial stretch forces. This study aims to test a technique employing a ring of prosthesis (acellular dermal allograft (ADM) or other biologics) placed around the NAC to offset these forces.
Methods/Technique:
Patients interested in mastopexy were recruited to participate in this prospective observational pilot study. Inclusion criteria are women with mild to moderate ptosis requesting breast lift, with or without, enlargement. Exclusion criteria are age < 18, previous breast surgery, and connective tissue disorders. The participants had pictures and measurements of their NAC taken preoperatively, intraoperatively, and postoperatively. Patients who declined use of ADM, but still consented to participate, were used as control.
Results/Complications:
Thus far, 33 women, average age 45.5 (range 18-76), have been recruited to participate in this ongoing study. Data from 24 patients (41 breasts), mean follow-up 175 days, were analyzed. Nine patients were excluded from analysis due to short follow up. Human ADM were used in 22 breasts, other biologics in 3, and 16 served as controls. The mean increases in NAC diameter were: 19.7% in the ADM group and 20% in the other biologics group; improvements compared to 28% increase in the control group (p = 0.055 and 0.199 respectively).
Conclusion:
Though the study is in its infancy, preliminary data suggests that our technique of NAC reinforcement with ADM may help mitigate the spread of NAC in periareolar mastopexy. These results encourage the continuation of the study with further patient recruitment and longer follow-up to confirm early findings.
