Is this a septum hematoma after rhinoplasty? (Photo)

    Call your plastic surgeon's office to evaluate this.  If you have a septal hemartoma, you need to have the area drained as soon as possible.  Hopefully you already did this.

Thank you for the question! It's much too early to worry about your results considering that you had your surgery done 10 days ago.  At this point you are most likely experiencing post-op swelling, which is preventing you from seeing final results. Swelling may take 6 to 12 months to completely resolve. In the meantime, you may see contour irregularities. Breathing difficulties should subside withing one month. Give it more time for your nose to "settle." 
 An in-person exam with a board-certified plastic surgeon would be the best way to assess your needs and obtain expert medical advice. Best of luck!

It is difficult to tell you if you have a septal hematoma from the photos, but if you have one it is an emergency and should be evaluated.
