Do I need maxillary mandibular advancement? (photos)

I've attatched a photo of my xrays. My oral surgeon is suggesting a genioplasty, but if my maxilla is also retruded, then I would like to go with a maxilla mandibular advancement even if it is only a few milimeters. If you could look at my photo and tell me what you think, that would be very helpful. Thank you!
