I have line and swelling on the side of my nose after Rhinoplasty. Is this normal? (photos)

Generally speaking, it can take 6 to 12 months to completely heal after surgery. Please keep in touch with your surgeon or his/her clinical team to discuss your ongoing concerns.

The postoperative time for most rhinoplasty patients is often fraught
with anxiety. During a rhinoplasty, the skin and soft tissues are often
completely separated from the underlying bone and cartilage framework. The
framework is modified and the skin is laid back down. These are big movements
that are often intended to create millimeter changes to the shape of the nose
once it heals. After a rhinoplasty the nose swells from the trauma of surgery
and the tissues become edematous. This makes the normally pliable skin firm and
causes the nose to take on a “weird” appearance in the first few weeks after
surgery. The nose continues to settle over the next few months as the edema
finally escapes and the soft tissues adapt to their new underlying framework.
It will take 6 months to a year to see a final result. Close follow-up with the
surgeon is essential. Assuming there is no infection, patients should allow at
least 6 months for the swelling to resolve and the tissues to soften before
contemplating any changes. At that point, a detailed exam and discussion will
help delineate the best treatment option.

You are very early in your recovery so it is too early to jump to conclusions.  While the indentation may represent several things (like a medial osteotomy) without knowing the details of your surgery it's very difficult to say with any accuracy.  Bring up your concerns with your surgeon and follow up closely with him/her to ensure the best result.
