I developed a Hemotoma in my face. How long it will take to disappear? (photos)

I have an orbital fracture and nasal fracture. My face was swollen. The swelling has gone down but I developed a hematoma in my face. Under the eye next to my nose. It is about one inch or inch and a half. I am concerned that it will not go away and cause some asymmetry in my face. That area feels numb but not as numb as at the beginning. It also feels heavy and bothers me when I smile. The color of bruising is practically gone but I can feel the lump which has a hard and rubbery feeling.  What can i do to speed up the healing process ? Is it recommended to get it drained?
