Hello and thank you for your question.  Although an exam in person is ideal, from your photographs alone it appears that you can benefit from a subtle tip rhinoplasty where the nasal tip cartilage is modified to straighten the columella -- the central portion of nasal skin between your nostrils where your "nose connects to the upper lip".  The modification of your nasal cartilage can be done with trimming, stitching or grafting.  However, the key in that last sentence is "grafting" -- typically your septum is harvested for cartilage in a rhinoplasty; if you already had a septoplasty, your septal cartilage was likely resected and you may need MTF (cadaver) cartilage to use as a graft to align the nasal tip as you mentioned.
