The lower eyelid area continues with the midface and cheek area. Some surgeons consider them as one unit, while other plastic surgeons consider them as completely separate. The goal of facial rejuvenation is to reduce the separation of the lower eyelid and midface, ie. eyelid bags & cheek sagging, that occurs with natural aging. One may be able to obtain some lift of the cheek with a lower blepharoplasty alone, but more commonly a separate procedure is required for adequate cheek lifting.
Only after a comprehensive evaluation can a surgeon help determine appropriate options for you. Best of luck.
