Gluteal augmentation (or buttock augmentation) is a medical procedure in plastic surgery that corrects deformities in the buttocks or enhances the size and shape (or contour) of the buttocks to achieve an aesthetic ideal.
Buttock augmentation can be achieved using gluteal implants which are inserted beneath each gluteus maximus muscle (or buttock). This is done by making an incision that is about 5 to 8 centimetres wide over the tailbone and then inserting a prosthesis above each buttock. This technique is the most effective for enlarging the buttocks and excess adipose fat can be used from the lower portion of the body.
Patients are typically anesthetize for this procedure and the healing process afterwards usually lasts between 6 and 8 months. During this period the gluteal muscle tissues relax allowing the incorporation of the inserted material into the buttock area.
