Will receiving a septoplasty make my nose look straighter?

Septoplasty addresses the midwall partition of the nose, which is mostly a functional surgery to improve airflow on the constricted side with minimal cosmetic effects noticeable from the outside (only in some rare and usually sever cases). Rhinoplasty (interchangeable called septorhinoplasty) is the actual nose job surgery to address a crooked nose. This usually includes septoplasty plus multiple other steps. They could be targeting either the bony part of the nose which will require the hammer +/- camouflage grafting techniques or the cartilaginous parts of the nose including the tip area which in modern days are usually addressed by repositioning, and restructuring techniques including grafts. 

 A septoplasty is performed in the back of the nose for medical necessity to only improve airflow dynamics in the nose, and will not change the shape of it. A rhinoplasty procedure is considered cosmetic, must be paid for by the patient, and can accomplish straightening the crooked nose.
