Splints left in 5 weeks post op on accident. Will it affect my post op negatively?

I had a primary open rhinoplasty and septoplasty along with some work on my turbinates. My doctor forgot to remove two splints from my nose 5 weeks post op. I have had major swelling and it has not been going down. Could it be because of these splints? Was it bad that he didn't see them when he took the rest of them out one week post op? How can I help the swelling go down. Thank you!
