In this patient, the deviation to the left and the bulbous tip are evident, in addition to a modest dorsal hump. Through the particularly thin skin, one can see, on the left side, the junctional area between the nasal bone and the upper lateral cartilage. This transition zone (the “keystone”) is extremely delicate and important: in fact, this is precisely the level at which irregularities may occur—especially in thin-skinned patients—after lowering the hump and performing the surgical fractures (osteotomies) of the nasal bones. In this case, some irregularities are already visible preoperatively due to the deviation itself. The patient desires a natural appearance, but with a slight concavity (which may be desirable in a young woman) and with a tip that is more defined relative to the dorsum. Computer simulation is very important for this purpose.
