I am one month post op. From face lift. My right ear is still noticeably bigger than it was before surgery.

It is possible for the ear to look bigger after a facelift, but for a rather short time.  If there is some swelling of the ear structure, it will typically subside within a month or two.  On the other hand, the orientation and prominence of the ear typically does not change with a facelift.  Careful evaluation of the before/after photos done 3-6 months postop will reveal that the ear orientation has not changed.

While one month may seem like a long period of healing after a facelift, you are still early in the process and need to give things time. It is very common for the ear lobes to swell with facelift surgery and this is one of the last ares for swelling to dissipate. Stay in close contact with your surgeon, be patient and I do expect that this would improve over time.
