Can a severely deviated septum where breathing is not disrupted, be straightened with non-surgical procedures?

Hello and thank you for your question and photographs.  It appears that your nose is deviated with some asymmetry.  You may benefit from filler injection, but this is only temporary and will require continuous re-treatment.  Also, with each injection, there is a risk of arterial occlusion, ischemia, and other complications, more so than normally, because your nasal anatomy, and thus the vasculature, is likely distorted.   If you want a permanent fix, I would suggest finding the right aesthetic plastic surgeon to evaluate you for a rhinoplasty.  An aesthetic improvement, if performed carefully, is unlikely to compromise your breathing.  In your rhinoplasty consultation, be sure your surgeon addresses all your aesthetic goals and concerns specifically, and discusses the surgery details including the position and size of the incisions used (with actual photographs and not just digital animations), the risks and benefits of the procedure, recovery time, and post-operative course.  Also, be sure to see plenty of before-and-after pictures in women who have a similar nose appearance to yours, and preferably at different time frames (3 weeks out, 3 months out, etc) to more accurately predict your own surgical outcome.

After seeking out a board-certified plastic surgeon who specializes in aesthetic plastic surgery, I think the most important component of the consultation is to establish a good connection with your plastic surgeon.  It’s the connection that allows you to clearly define your desired nose outcome goals, the first step of this whole process. If you don’t feel you have a good connection with your plastic surgeon after your consultation, he/she may not be the best surgeon for you.

QUICK ANSWER: Yes, it is possible to "fix" a deviation with a properly performed nonsurgical rhinoplasty using fillers (e.g., Restylane, Juvederm, Radiesse, etc.). This is done by filling in contour irregularities, such as concavities, to create the illusion of a less crooked nose. 
LONG ANSWER:  Depending on the severity of your asymmetry (will be better assessed in person and with standard rhinoplasty photography), as well as your goals and expectations, you may be better suited for either surgical or non-surgical rhinoplasty. I think the best thing to do would be to consult a physician who is experienced with both surgical and nonsurgical rhinoplasty techniques, that way you will receive an unbiased and expert opinion. Moreover, since you are worried about not making your breathing any worse, it would be wise to consult with a surgeon who performs both cosmetic and function septorhinoplasty on a regular basis (e.g., specialty training in Facial Plastic Surgery or Plastic Surgery). As an aside, I routinely counsel patients during their pre-operative rhinoplasty consultation that their is a very small chance of making the breathing worse; however, this would be rare and I can almost guarantee that their breathing after surgery will be either the same or better than what it used to be. 
Take home point: both surgical and nonsurgical rhinoplasty have their separate advantages and disadvantages. It is up to you, the patient, with guidance from an experienced surgeon, to determine which modality would be best for you.Hope this helps!
