Unhappy with chin implant size, would an XL implant make a difference?

Your pre-op photo shows a small recessive chin. The post-op photo shows an improvement but it is still recessive. There is actually not a big difference a large implant and extra large implant. I think that a sliding genioplasty would have been preferred in order to truly balance your face. With a sliding genioplasty, the chin can be advanced 9-10. This generally requires a custom implant.

It is sometimes very difficult to select appropriate impant size. We routinelly use two sizers in surgery before making final decision; however it is not always enough. Patient has much more time after surgery to check result and make up his mind. There is nothing wrong replacing current implant with larger one. Good luck.

Thank you so much for your question! Based on your pictures the post-operation result is successful. However, if you desire to enlarge your chin appearance with a little bit of a difference then you can benefit from XL size. Hope it helped!
