Deviated Septum Prior and Now a Slightly Broken Nose. Is It Time to Fix This? Worried About Risks.

You appear to have a few things going on that are very reasonable to improve with a septo-rhinoplasty. Your bridge can be addressed as well as your external deviation and nasal obstruction. A complete nasal examination will allow for a better assessment of what needs to be done.

Consult with a board certified rhinoplasty surgeon who can perform preoperative digital morphing. This will allow you to give your input of what changes you'd like made and allow your surgeon to give you a better sense of what changes are possible.

Your posted photos show an S-shaped septal deviation, obvious nasal valve collapse (that is why the nostrils collapse), notching of the right nostril rim and a dorsal hump. I suspect there is more here than just a broken nose. These S-shaped deviations are harder to treat than the C-shaped or oblique deviations because the cartilage is distorted more and has some shape memory.

I suspect you would benefit from take down of the hump, sidewall osteotomies to close the resulting open roof, septoplasty with shaping suture to straighten the septum and cartilage grafts to keep the valves open so they do not collapse on inspiration and to reduce the nostril rim notching. There are probably other issues such as narrow nostril floors that cannot be fully discerned by these few limited photos in the absence of a physical examination.

Make sure you see more than one surgeon in consultation and that any surgeon you see does a complete nasal examination before proceeding.

My response to your question/post does not represent formal medical advice or constitute a doctor patient relationship. You need to consult with i.e. personally see a board certified plastic surgeon in order to receive a formal evaluation and develop a doctor patient relationship.

If you are planning on a rhinoplasty, specifically a reduction rhinoplasty (reducing the hump or deprojecting the tip) I would recommend addressing a deviated septum as well.  Even if you currently had minimal symptoms changing the shape of your nose can exacerbate any nasal obstruction from a deviated septum.  Also, sometimes cartilage grafts are needed during a rhinoplasty and your septal cartilage is a great source.  So besides improving your breathing the septum may be needed for your rhinoplasty.  I hope this helps.
