Surgical repair and alteration of the septum. Literally, this term describes reshaping the septum. This is usually done for functional breathing purposes, but sometimes it is done for cosmetic purposes, as the septum is responsible for the deviation of the lower two-thirds of the nose.

Septoplasty can be done using an endonasal technique, which means it can be done with no external incisions. This is the way it is most commonly done. The ways a septoplasty can be done vary greatly.
