I had Septoplasty done approximately three years ago and since my nose has flatten! What would cause my nose to alter?

This would be very unusual but if the septoplasty procedure damaged or removed the support for the nasal tip or bridge, your nose could flatten over time. This can be remedied, however, with a septorhinoplasty procedure. Consult with a rhinoplasty expert for specific advice. I hope this information is helpful for you.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

Unless the septum has collapsed, which is highly unlikely, it would not affect the shape of your nose.  Best to have an examination by a plastic surgeon to make an assessment.  Best of luck, Dr. Michael OmidiAn in-person exam with a board-certified plastic surgeon is the best way to assess your needs and provide true medical advice. The response to the question does not constitute a doctor patient relationship or formal advice.

Your doctor may have performed a rhinoplasty at the same time.  I would return to him and ask him about your concerns.  It is possible that you only had a septoplasty and depending on you pre-op severity he may have removed your septal cartilage to improve your nasal breathing.  This may have caused a lack of dorsal support, saddle nose deformity.  This can easily be treated using a secondary surgery using cartilage grafts.
