A facelift is designed to smooth the neck, lift the jowls, add crispness to the jaw line, and to elevate the cheeks. As a general rule, smoothing the neck, improving the jaw line, and lifting the jowls are the easiest to achieve. The higher you go on the face, the harder it is to get great results. For many years the standard facelift procedure gave great results to the neck, jaw line, and jowls, but often failed at lifting the cheeks, especially the upper portion of the cheeks. For this reason, newer techniques have been developed to address the difficulties with the upper cheeks ( a high SMAS facelift, the third suture in a MACS lift, are examples). As far as a deep plane facelift is concerned, how well it will address the cheeks and upper nasolabial folds depends on where your surgeon designed the upper edge of the flap. A flap that starts below the zygomatic arch will not lift the upper portion of the cheek very well. A flap that starts at the top of the zygomatic arch will give much better cheek elevation. Given your description, it is likely that the flap did not include the upper part of the zygomatic arch and is the reason why the results in the cheeks was not as good as you would have liked. At this point (assuming you don't want to redo the entire lift), cheek implants are a reasonable option. A great non-surgical option would be to have one of the high volume fillers injected into the cheeks (Radiesse or Perlane), which would give an immediate improvement with essentially no down-time.
