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

It's hard to tell from the picture whether or not you have a hematoma or bruising. Swelling and temporary numbness are common after trauma and resolve however it could take several weeks. If the infraorbital nerve below the eye is severed the numbness could be permanent. You stated that you had an orbital and nasal fracture. I assume that you know this from a maxilofacial CT scan that has been done. I would take your images and follow up with a facial plastic surgeon who can give you a detailed examination and ensure that you are healing normally and that you do not have a hematoma.

I recommend seeing a facial plastic surgeon or oculoplastic surgeon experienced in trauma ASAP. It is not normal to develop a hematoma and will take some time to recover.

Facial fractures will involve swelling bruising and sometimes hematomas. It can also be difficult to differentiate between them especially if the fracture altered your cheekbone. In general you should see a significant improvement by about 3 weeks. Be sure to follow up with your plastic surgeon during that time frame.
