It is important to remember that whenever a rhinoplasty is performed, it involves two separate procedures, one to the right side of the nose and one to the left. In every stage of the surgery, great attention must be paid to symmetry. The cartilage on both sides of the nose tip must be removed to exactly the same degree or and asymmetric tip will result. Asymmetries may also occur due to unequal scarring during the healing process and not reveal themselves until months or even years after the fact. For a successful revision rhinoplasty, the surgeon must pay careful attention to symmetry at every stage of the procedure and through extensive experience anticipate how the scar tissue is likely to form and adjust accordingly for a final, aesthetically satisfying result.
