Which would you recommend; Chin Implant Or Sliding genioplasty and Rhinoplasty? (photos)

The photograph demonstrates  a recessive chin which can be augmented with a chin implant for cosmetic purposes only, versus performing a sliding genioplasty for both cosmetic and functional bite issues. A sliding genioplasty is performed as an inpatient procedure at a hospital with 1-2 days stay overnight versus a chin implant which can be performed under local anesthesia as an outpatient procedure. A rhinoplasty can also be performed at the same time.  For many examples and more information, please see the link below

I believe the best thing to do is to take X-rays of jaw and see if you need jaw surgery or just chin. If need jaw surgery, neither one of the treatments would be ideal. 

It certainly is possible to combine chin augmentation surgery with rhinoplasty. Like you mentioned sliding genioplasty can achieve more powerful results in that vertical chin height changes can be made in addition to bringing the chin forward.In my practice sliding genioplasty is done as an outpatient procedure, even if combined with rhinoplasty. It's hard to know if either chin implantation or sliding genioplasty could achieve the level of augmentation that you morphed in your photo. Either approach should be able to provide a significant amount of improvement though.You can read more about chin implantation and sliding genioplasty at my web reference link below.
