Why Do I Have an Indent on my Upper Right Butt Cheek?

Indentation in the buttock area can be from trauma where you can get a bit of fat loss, or fat from the trauma can shift to an adjacent location, usually above the area of trauma. If that isn’t the case, an old intramuscular injection can create it. But usually there isn’t any other real reason to get a big indentation in the cheek area. But for treatment, options can include some fat transfer with liposuction of the surrounding area if the surround areas are more full, and fat transfer to mild indentation. This can be done with release of any scar tissue you may have in the underneath area. Second option is to have Sculptra injections to the area to gently lift up the depressed tissue.

It is difficult to answer your question accurately without photographs.  There must be something in the recent past that might explain why you have developed an indentation only on one side.  Recent buttock trauma, injection, infection or surgery might explain this new indentation.  I would consult with a board certified plastic surgeon to help determine the cause and the best treatment.  Best of luck!
