Importance
Fat grafting has proven to be a useful adjunct to breast reconstruction for the treatment of contour irregularities and volume deficits, but the proposed FDA regulations may severely limit the ability of plastic surgeons to continue its use in this clinical context.
Objective
To determine if fat grafting has an effect on patient-reported outcomes (PROs) in breast reconstruction patients.
Design
Longitudinal, multicenter, prospective cohort study conducted between February 2012 and July 2016.
Setting
Conducted at the 11 study sites associated with the Mastectomy Reconstruction Outcomes Consortium (MROC) study.
Participants
Eligible patients included women 18 years and older presenting for breast reconstruction following mastectomy with at least two years of follow-up. All primary procedure types (implant- and flap-based) were eligible. Patients were excluded if they had not completed breast mound reconstruction by one year after mastectomy.
Interventions
Fat grafting as an adjunct to breast reconstruction.
Main outcomes and measures
Primary end points were patient-reported outcome measures as assessed by the validated BREAST-Q, with higher scores indicating better health-related quality of life. Survey subscales included breast satisfaction, as well as psychosocial, physical, and sexual well-being. Patient-reported outcomes were compared between fat grafted and non-fat grafted patients.
Results
A total of 2,048 women were included, with 165 undergoing fat grafting between years one and two. One year postoperatively, patients who later underwent fat grafting reported significantly lower breast satisfaction (adjusted mean difference (AMD) = −4.74, CI −8.21 to −1.28, p=0.008), psychosocial well-being (AMD = −3.87, CI −7.33 to −0.40, p=0.029), and sexual well-being (AMD = −5.59, CI −9.70 to −1.47, p=0.008), compared to those who did not receive subsequent fat grafting. Following fat grafting, the fat grafted cohort reported similar breast satisfaction (AMD = −0.68, CI −4.42 to 3.06, p=0.719), psychosocial well-being (AMD = −0.59, CI −3.92 to 2.74, p=0.728), and sexual well-being (AMD = −2.94, CI −7.01 to 1.12, p=0.154) at two years postoperatively.
Conclusions and relevance
Fat grafting improves breast satisfaction, psychosocial well-being, and sexual well-being in breast reconstruction patients.
