Abstract

Background: Gluteal fat transfer has witnessed a rapid increase
in popularity, with fat transfer becoming an essential
used tool in aesthetic surgery. Many studies detailed the technique
of the procedure, while few explored the amount of fat
needed for optimum results.
This study aims to investigate the volume of fat
that needs to be injected into the buttock, about the
total surface area injected, and if that would be affected by the
presence of preoperative gluteal ptosis.
Methods: This study included 20 female patients seeking
glutleoplasty by fat transfer. Patients were assessed preoperatively,
and preoperative gluteal projection was recorded. They
underwent gluteal augmentation using autologous fat transfer.
Postoperatively, they were assessed, and postoperative gluteal
projection was recorded immediately, at 1-month, and 2-months.
The volume of fat injected per centimeter was calculated.
Results: The mean volume of injection per unit area within
the study was 5.24ml/cm2 (2.91-7.88ml/cm2). Mean postoperative
gluteal projection (immediately: 19.72cm, at 1-month:
20.90cm, at 2 months: 20.22 cm), was significantly higher than
the mean preoperative projection (16.92cm). The area of injection
was significantly higher in cases with ptosis (187cm2),
than in cases without ptosis (158.67cm2).
Conclusions: There was a significant improvement in postoperative
projection immediately, at 1 and 2 months, with theThe
highest projection was achieved at 1-month postoperatively. TheThe
mean volume of injection per unit area within the study was
5.24ml/cm2.
