Aging Face Anatomy

Knowing several structures on the surface of the face will help improve understanding of the aging terminology.

1- Eye-Cheek Junction- This is a critical area in evaluating the aging face. Ideally this area is a smooth transition from the eye to the cheek.
2- Tragus- Part of the ear which is located on the face. In facelift surgery, an incision can be made behind this part of the ear (retrotragal) or in front of this part (pretragal)
3- Zygomatic Insertion Point- Location of the origin of zygomaticus major muscle determined by P Miller, S Smith, AR Shah (yes that is Dr. Shah). Serves also as a useful point to help identify platysma muscle location within the face.
4- Malar fat pad- Location of fat pad in face
5- Nasolabial fold- A fold which may become more prominent with aging. Note, that every person has a nasolabial fold and that its elimination will look unnatural
6- White part of the lip- As we age this part of the lip looks longer and the red lips become thinner.
7- Mandibular angle- Good bone structure may help lead to improved jawline and neckline
8- Marionette line- Lines along inferior lip which may become more prominent with aging.
9- Jowl- The jowl below the jawline can be improved with liposuction, the part above the jaw in the face is generally not recommended for liposuction.
10- Chin projection- A more prominent chin can help with providing more definition to the neck
11- Submandibular glands- In some patients, these glands may be prominent on the side view of the neck. They are generally not recommended to be removed for aesthetic purposes as they provide almost 80% of saliva.
12- Hyoid bone- A critical bone in the neck which helps determine how much of an L can be created in the neck.
13- Sternocleidomastoid muscle- A neck muscle who is typically much more prominent in men and should not be removed for aesthetic purposes.

There are differences between our faces and necks which will limit how much improvement we can see in a facelift.  Much of this difference has to do with innate structures in our neck such as the chin and a bone in our neck called the hyoid bone.  You can feel this part of your neck because if you stick your tongue out the bottom of the tongue will move this portion of the neck forward.

Dr. Shah's practice is located in Chicago, Illinois in the goldcoast area in the landmark Watertowr building. His practice is one of the only facial plastic practices with a large contigent of international clientele mixed in with a growing base of Chicago and Chicagoland patients.
