Dr. Nara performs this by either surgically using your own fat derived from your body, inserting specialised implants or using a combination of fat grafting and implants. The fat is then carefully processed through specialised means to improve the viability of fat.  This fat is then carefully injected back to the buttock region at targeted points so that you experience the enhancement.  In saying so, the viability of fat graft is always a concern after surgery since 100% of fat retention is never possible.  This is because fat may gradually be absorbed back into your system.  Various factors can affect this such as the aging process, metabolic changes in your body, illness or even injury.

This varies from individual and individual.  Graft retention is also not uniform throughout the entire buttock region.  In principle, all the fat graft inserted into the buttock does not remain there forever.  On the same token, it is difficult to predict whether these fat cells will remain there consistently and permanently over time.  

There are risks and complications associated with any operation.  Specific to buttock aessthetic surgery, there have been reports of unfortunate deaths around the world during the procedure.  This was due to the fat being injected too deep in the region.  The fat entered the veins which then travelled up to the lungs resulting in the inability to breathe or respiratory arrest.  Therefore, specific understanding of the anatomy and medical experience of the buttock region is very important.  Many techniques are now used to prevent this risk from occurring but remains to be a risk.  

Risks with buttock aesthetic surgery are bleeding, infection, seroma, scarring, deep venous thrombosis, pulmonary embolism, heart attack, lung infection, pressure sores, ulcers, assymetry, contour irregularities, and even death.  Other related risks specific to your individual surgery will be discussed with your unique consultation with Dr Nara.

Yes.  The shape of your hip is naturally occurring where there are vast variations of shape and anatomy from person to person. This is certainly unique to you.   Some are conscious about the appearance of their hips and seek an aesthetic surgical change to it.  This can be addressed through various means of liposculpture and fat grafting techniques that will be discussed thoroughly at your cosmetic consultation with Dr Nara.
