The rule of thumb with nasal shaping is that after one week as the splint comes off the nose should look pretty good. There are exceptions however, and patients with thick skin usually will have to have greater patience to wait out the swelling and stiffness in the skin which can persist for six months or longer. Results can only be judged as the swelling and stiffness have resolved the nasal shape is revealed.
Visible tip grafts can pose special problems. A graft is cartilage tissue usually taken from inside the nose placed to support the airway improving breathing, or to support the shape of the nose as a visible or an invisible graft. Visible means the graft is placed under the skin and is meant to be seen by showing through and setting the shape or appearance. When the nasal skin is thin there is a risk that the graft will show excessively, or appear uneven or unnatural. Still, at two weeks it is too early to tell if the problem will persist, and if it does to determine just how much adjustment is required. You may be right and the graft may not be all that was expected, but it is best to wait it out if you can.
Best of luck,
