I am 13 weeks post facelift. I have swollen areas in front of both my ears that extends below ear? (Photo)

 From your photographs there appears to be significantly more swelling in the right aspect of your face then the left. If there was no response at all to the steroid dose pack, then persistent swelling may not be the underlying issue. It would be unusual for there to be a delayed hematoma this long after your initial procedure.  It is possible that there could be damage to the underlying parotid gland. Ultrasound could help evaluate this area.  Conservative treatments such as lymphatic massage, head elevation, and anti-inflammatories may help and have very few downsides. I would follow up closely with your plastic surgeon 

If your at 3 months post op I would consider a salivary cyst originating in the underlying parotid salivary gland.   This would require surgical management. Consider with your plastic surgeon.
