Can I Have Any Nose I Want?
While it is true that cosmetic rhinoplasty can create dramatic transformations in a person's appearance, it has significant and real limitations. It is not possible to change all nasal features and as a result there is a limit to how much a person can change their particular nose. The resiliency of cartilage, the orientation of the surrounding facial bones and the thickness of the nasal skin all contribute to the appearance of the nose. Some of these factors can not be changed surgically and limit the degree of change possible. In summary, you probably can't have any nose but you can have an improved version of yours that with the appropriate expectations, you will be very happy with.
Expectations setting is the responsibility of your surgeon. During your consultation, your surgeon should discuss the limitations that apply to you based on your nasal and facial features. Computer imaging is incredibly helpful for showing the patient what they should expect from surgery.
