More than likely you are ready as long as your cartilages are mature and firm to touch on examination. You have an under projected tip which must be augmented in several ways including tip grafting with cartilage and cartilage strutting of your columella. If your cartilages are soft you cannot get a predictable result. Hump removal will help then profile less if the tip is not properly done. Do not have a profile-plasty like you see on so many TV stars and news reporters.They have a diamond shaped widening and a flat wide plateau for a bridge and a lowered profile. These are stigmata of an incomplete nose job done by a doctor who guarantees no bruising. Have the bridge narrowed by osteotomies and appropriate infracturing and straightening even though you might have transient black and blue side effects.
