Are my desired rhinoplasty results obtainable without a premaxillary implant? (Photo)

Based on your photos, a septal extension graft in conjunction with extended spreader grafts would help to lengthen and counter-rotate your nose to create a more balanced nasolabial angle and greater tip projection.  The degree of counter-rotation and projection your photos you seek will likely require rib cartilage as it is a fairly dramatic change.  

I don't think a premaxilary implant will be of any benefit whatsoever.  It is not clear what you need from the limited photos you submitted. You should go on a few different consults with experienced rhinoplasty surgeons to determine your options.

Your short under projected nose needs a septal extension graft. What you describe won't give u what u want. 

This is a good question to ask.  It's not talked about much but midface or maxillary weakness or retroposition as we sometimes describe it can limit the overall outcome and I guess I would say "presentation" of rhinoplasty results on the Asian face.  One of the best rhinoplasty surgeons in America, Dr. Dean Toriumi, has a very well-known before-and-after photo of the Southeast Asian woman with a flat midface and nasal features typical of her background.  In the after photo there is detailed conversations and descriptions about augmentation of the bridge and tip work with cartilage but what is not always mentioned is she also had premaxillary augmentation.  Augmentation of the premaxillary area in the Asian face in the context of a rhinoplasty sometimes is needed to help a person reach their goals.  In your photographs it is a little difficult to say but my general analysis is that your goals are probably obtainable without premaxillary augmentation.  I cannot say for sure without a physical exam but I think you're at least on the right track and probably have been to some good consultations because many patients never even know that this is a potential component of their surgery.Chase Lay, MDAsian facial plastics specialist
