I have an under-eye bruising 3 months after Rhinoplasty. Is this normal?

I underwent an open rhinoplasty (to reshape the tip of my nose) and septoplasty approximately 3 months ago. After the surgery I had quite big and very dark (dark purple, almost black) ecchymoses under the eyes. They resolved in time, however on the right side (where the bruising was more pronounced) there is is still a yellowish, light brown pigmentation under the eye. Is it normal for this to perisist 3 months after the surgery? Will it completely resolve in time? Thank you in advance for the answer!
