Males always have a stronger posture, unrelenting, indestructible and tough image due to cultural norms in society. Adding the bony and muscled male body on top of this, we see that the male nose structure has to be a little bit tougher than females. Tougher facial lines and facial hair also support this. Appropriately preserving natural lines, and even not hiding some faults have been the key to a successful male cosmetic nose surgery.
Of course, some rules may be bent in line with patients' reasonable requests. However in general, exceptions don't break the rule. The ridge of the nose is straight, while its tip is at a 90-95 degree angle. Male nose is usually a bit larger. It has to be compatible with the face and the physical structure. Of course, the image that the patient wants to see on the mirror also has to be considered before the surgery. However, the general rules are followed as much as possible.
