Can plastic surgery make hip bones smaller?

No: But liposuction can alter the soft tissue in this area.

No: It won't change the underlying bones but the fat overlying the hips can be treated with liposuction.

Making hips smaller: No, we can not change the structure of your bony pelvis or leg bones. All we can do is remove overlying fat (with liposuction), or perhaps tighten up loose skin (with a surgical thigh lift operation).

Not the bones: Only the fat overlying tem in your hips... That is commonly reduced through liposuction.
