This is a very common question in my practice. The midface is the area just beneath the lower eyelids; if you draw a line from the corner of the upper lip to the top of the ear, the midface lies above this line.
A traditional facelift cannot elevate the midface. This is why some patients have the lateral sweep deformity (the situation where the lower face is pulled and the midface is droopy). However, a deep plane facelift can lift the midface and the lower face together thereby avoiding the pulled look. Although many surgeons do a midface lift separate from a facelift, in my opinion this is of no benefit. A well done deep plane facelift will elevate both these areas harmoniously and produce excellent rejuvenation of the face.
