In profile view, the ideal angle between the nose and the forehead measures 115-135 degrees (Figure 4). Larger angles will make the nose look longer, while smaller angles make your nose appear shorter. Ideal outcomes can sometimes be reached just by modifying this angle without altering other parts.
In profile view, the proper angle formed by the nose and the face is 30 to 40 degrees. The ideal angle is 36 degrees (Figure 5). Your nose will look larger as this angle increases.
In profile view, the proper angle formed by the nose and the chin is 120-132 degrees. In this case, the upper lip is typically 4 mm away from the line connecting the nose to the chin, while the lower lip is placed at 2 mm from this line. Clearly, if over- or under-projected chin does not meet this criterion (Figure 6).
The first step in rhinoplasty is to visually appraise the nose and compare its dimensions to see whether it is in proportion to other parts of the face. The criteria described above are only a part of comprehensive criteria against which the nose should be appraised prior to surgery. You should analyze your photo and find the flaws in your nose before the surgery. Using this type of analysis and the applications developed for this purpose, you can better imagine what your nose will look life after the surgery and discuss your desirable outcomes during the pre-surgery consultation session.
