Septoplasty alone to address a deviated nasal septum is not meant to change the shape and appearance of your nose, it is to improve the breathing and nasal obstruction.
A rhinoplasty can also be done at the same time (Septorhinoplasty) to change the shape of the nose.
Septorhinoplasty can be functional or cosmetic, this will depend on the assessment by your surgeon at the time of consultation.
