How do they measure rhinoplasty?

In performing rhinoplasty today most of the changes we make are measured in millimeters. That's because we don't just reduce the nose anymore but we structure the nose to give it balance in the face and don't sacrifice function for cosmesis.

Hello and thank you for your question.  You are exactly right:  rhinoplasty is a very precise type of surgery which must be performed based on millimeters in order to achieve a natural look.  In surgery we often use calipers to measure and experience to judge.  Based on your
description, you may benefit from a tip refining rhinoplasty. Your surgeon can
accomplish this by trimming, suturing, and reshaping the cartilage in your
lower nose. You may also benefit from a conservative dorsal hump reduction.  Make sure you specifically look at before and after
pictures of real patients who have had this surgery performed by your surgeon
and not just a computer animation system. The most important
aspect is to find a surgeon you are comfortable with. I recommend that you seek
consultation with a qualified board-certified plastic surgeon who can evaluate
you in person.
Best wishes and good luck.

Rhinoplasty really is a marriage of art and science, so my answer may not be as straightforward as you'd like. Patients don't often have their surgeries planned down to the millimeter. However, surgeons generally use calipers to help them measure during surgery. During the consultation process, I communicate with each patient to help ensure we're both working toward the same goal. I find that this matters much more than specific measurements. It is also possible to reduce the size of your tip without altering its shape a great deal. It's important to see a board-certified plastic surgeon who is extensively experienced in rhinoplasty, since it's a challenging procedure.

Rhinoplasty is a very visual and a very artistic operation.  Experienced surgeons will typically do planning with photo tools with the patient in the office, and then take the model to the OR with them to see how close they can deliver.  Be sure to discuss your goals and concerns with your board certified plastic surgeon and consider the pros and the cons. Be certain your surgeon is properly certified.  I've attached a link where you can start your search. 

Rhinoplasty is a form of artwork that is mill measured in millimeters. Digital computer imaging would be helpful to understand what can be accomplished with your nose upon your facial features. Communication between the patient and the surgeon is of utmost importance to understand what your goals are regarding  a three-dimensional surgical procedure.  For more information  and many before-and-after examples, please see the link and the video below 

You would need to be seen in person to be properly evaluated to determine what might be appropriate for you.  It is hard to say what might be reasonable without at least photos.

Thank you for your question.  I think you should arrange a consultation with a board certified cosmetic surgeon. Once he had examined your nose, then you can have a discussion with him regarding your expectations, and he can advise you about what can be achieved realistically.This will help you make up your mind whether you want to go ahead or not.

It is not possible to exactly predict how a nose will heal.  Also, rhinoplasty is as much an artistic endeavor as it is a structural operation.  With this procedure, it is a combination of all three elements and the surgeon's judgement and experience that matter.  No surgeon can tell you exactly how much he/she will decide to add or remove from you nose.  It is always an estimate.
