Objectives: I will show you Sono-anatomy for the buttock injection.
Introduction: The anatomy for buttock injection is simple.
Under the fat, there is Gluteus-Maximus.
When deep injection into the muscle, the muscle is-gonna contract, and the patient feels pain.
The target tissue is the fat layer, not into the muscle.
Under the Gluteus-Maximus, you have short piriformis muscle.
It runs from sacrum to greater trochanter.
It is an important landmark.
Materials / method: To treat skin atrophy and discoloration, I inject in the-dermis, with dilution.
To improve skin tightening or to treat skin fold, I injected filler into superficial fat layer under the dermis .
For volumizing, I injected into deep fat layer under the superficial fascia.
Results: SONO-image fi
In the superficial layer, each fat lobule has cuboid shape, called "cuboid fat".
This fascia looks like a honeycomb, called this "honeycomb fascia".
Honeycomb fascia surround fat lobule tightly and hold the “dermis” tightly to the "superficial fascia".
Superficial-fat layer is im-mobile and solid / to protect against external forces.
This im-mobile space is named “protective adipo-fascial system (PAFS)’’
Deep-fat layer(red) is a mobile layer , to lubricate musculo-skeletal movement.
Each fat lobule is flat and loose, called “flat fat .“lubricant adipo-fascial system (LAFS)’
Conclusion: Looking at upper layer, Superficial layer contains solid cuboid fat and honeycomb fascia. This layer is immobile structure, showing hardly stretched, compressed.
Looking at , Deep fat layer is stretched and mobile structure. So, you better inject volumizing-filler in the deep fat layer
