The most common septoplasty incisions are known as the “hemi-transfixion” or “complete transfixion” incisions.
The use of a complete transfixion incision, which goes from one side of the septum all the way through to the other side, will most often result in a reduction of the height of the nasal tip by 1-2 millimeters. If this is desirable, because the projection of the nose away from the face is slightly greater than ideal for your face, then this would likely be the best approach.
Alternatively, a hemi-transfixion incision technique employs an incision on 1 side of the septum only so that there is little change in the nasal tip post-operatively. The incision may also be made in the immediate area of the deformity in the nasal septum; however, I use this approach less commonly since I have less control of its effect on the other side of the septum, in this case. I generally prefer to use a hemi-transfixion incision, unless there is a desire to drop the height of the nasal tip.
