First, no rhinoplasty is perfect and some deviation is inevitable with all septal work because no one can get it perfectly straight. In addition, at 4 months you likely still have swelling. Best to see your surgeon to discuss if concerned.
Thank you for your question. I concur with your previous advice about returning to the previous plastic surgeon. As there are numerous rhinoplasty techniques, he/she would know best. At your current stage you still do have an element of swelling which needs to be factored in as well. This swelling could take upwards of one year to fully subside. I hope this helps you and good luck.

Rather than start to plan a revision, I would revisit the surgeon who did your surgery and ask about your concerns. There is still swelling at 3 months. The surgeon will know what has been done and what is expected at this interval.
