Butt Implants: Intramuscular versus Under the Muscle

It is not possible to put under the muscle an implant of 400 cc.
The under muscular pocket, only allows
smaller implants, volume around 250 cc, and the projection obtained in this
space is going to be in the upper half of the buttocks. Usually putting the
implants in this space (under the muscle) don’t fill the lower pole of your
buttocks and runs a greater risk of impinging on the sciatic nerve.

IF you want a lot of projection, a rounder look on the lower
part of your buttocks from the side and you want the implants look natural, the
intra-muscular space (within the muscle) is the correct plane, so that there
are around 3 cm of muscle fibers covering the implant for best protection, in
this plane the implant can’t shift around, does not sag, less distortion
and visibility.

The "best" implant (size and
shape) for you, are based on buttocks dimentions ((length and width.) of your gluteal area, body type, your skin quality and underlying tissues, including
the elasticity of the muscles measured at
your consultation. An intramuscular location is limited usually no
greater than 500 cc.



Attempting to place an overly large implant in the buttock (intra-muscular
plane) will not result in a pleasing appearance and can carry a high risk of
complications.

Many surgeons do not perform the intramuscular approach because
this operation requires the most meticulous dissection for soft tissue coverage
of the implants. It is a surgery that requires great expertise and finesse to
achieve a good results.

There is no surgical technique where buttock implants are placed under the gluteus maximus muscle. That is a very unsafe plane of implant location as it will compress the sciatic nerve. There is intramuscular buttock implant placement and subfascial (above the muscle) buttock implant placement. These are the two accepted pocket locations for buttock implants.
