Subfascial/Intramuscular Dual-Plane Gluteal Implantation and Supplemental Fat Grafting: A Novel Technique for Buttock Augmentation.

[BACKGROUND] Much debate exists within the current literature as to which plane is safest and most effective for gluteal implant buttock augmentation. A novel subfascial/intramuscular (SF/IM) dual-plane technique appears to combine the benefits of each plane.

[OBJECTIVES] The aim of this study was to describe our experience with SF/IM plane gluteal implantation, and to discuss its indications, efficacy, and safety, and offer recommendations on its proper use.

[METHODS] A retrospective chart review was conducted of 175 consecutive cases of gluteal augmentation with solid silicone implants in the SF/IM pocket, with and without supplemental autologous fat transfer. Outcomes from all patients were analyzed to determine the rate of complication and need for surgical revision.

[RESULTS] In 175 cases of bilateral buttock augmentation with gluteal implantation using the SF/IM pocket, the most common complication was infection. This complication was seen in 13 cases (7.43%), 7 (4%) of which were superficial and did not require surgical intervention. Other complications included dehiscence, seroma, capsular contracture, and implant migration.

[CONCLUSIONS] The SF/IM gluteal implantation, in combination with liposculpture and autologous fat transfer into the overlaying subcutaneous space, allows for a durable cosmetic augmentation of the buttocks in patients lacking sufficient volume for augmentation with fat transfer alone. This technique was found to have complication rates similar to those of other established augmentation techniques, as well the cosmetic advantages of a large, stable pocket with thick, soft tissue coverage of the inferior pole.
