How High Can Nose Heightening Go? (photo)

8 mm is probably pushing it, but dorsal augmentation with autologous grafts (your own body) will be able to consistently provide 5-7 mm of height to your bridge.  I suspect that even with that amount of augmentation, you would be very pleased with your result.  The limiting factor for the the appropriate amount of dorsal augmentation is probably your tip projection (how tall your tip is) because that will have to be increased to match your augmented dorsum.  Achieiving significant tip projection safely and reliably is more challenging than dorsal augmentation.  

First, there is nothing abnormal about your nose as I see many noses just like yours all the time and if anyone mistreats you because of your nose, you should definitely avoid them.

Instead of focusing on the dorsal height in millimeters, you should think about what would make your nose aesthetically pleasing to you. Though the dorsal height plays an important role in achieving an attractive nose, the aesthetic evaluation is much more sophisticated. 

In general, raising nose dorsal height 8-10mm in primary Asian nose surgery is not common.

 

 

Dorsal Augmentation is a common maneuver in Asian Rhinoplasty.  This would definately be helpful in your case. The simplest way to see if you would be happy with this is to have a non-surgical dorsal augmentation with filler. This is a temporary treatment and I would not repeat it too often if you are considering a permanent solution such as surgery. While implants are commonly used in Asia, they have a very poor long term track record. Problems include extrusion through the skin and infection.  The best long term solution is to use cartilage from your septum, ear or rib to augment the dorsum and the tip.  Best wishes.

4-5 millimeters is about all that can be safely augmented with a silastic implant to the bridge of the nose.  

 A large graft like the one you desribe does not sound reasonable and your skin would probably not accommodate it.
