Upon request of many patients, I add some explantations in cheek bone reduction.
Cheek bone reduction
Mechanism of 3 points cheek bone reduction.
To make the zygomatic curve more natural and smoother, OZ doctors cut 3 points in zygoma including anterior cut through intraoral incision, middle greenstick fracture at zygomatico temporal suture line and posterior cut through a stab incision in sideburn.
Preauricular stab incision is so short (about 3 mm) and is concealed in hair and sideburn, it is innoticeable.
Controversies in zygoma reduction.
- Bone shaving vs. bone movement.
Thickness of zygomatic bone is only 1 mm.
So, bone shaving usually yield less than 1 mm change.
On the other hands, bone can be moved inward much more upto 1
cm because there is a empty space between the zygoma and skull.
- Fixation vs nonfixation
After mobilization of zygomatic bone, I usually don't fix the
moved bone.
To maintain the stability of the moved bone, I keep trying to
maintain the integrity of periosteum and limit the dissection
of zygoma.
By the aids of this limited dissection, bone can be fixed by natural
forces of muscles and periosteum.
It is a great advantage not to use any foreign material in fixating
the moved bone segment.
- Incisions of zygomatic reduction
There are many types of incisions in zygomatic reduction.
The oldest one is scalp incision and intraoral incision. Because
of the scar, morbidity and risk of facial nerve injury, it is
rarely used.
The most popular one is intraoral and preauricular incision. By
the aid of this approach doctors can avoid the risk of injury
to facial nerve. By incising only 3 mm in sideburn, preauricular
incision become innoticeable.
If the patient needs only anterior cheek reduction, the opertion
can be performed only through intraoral incsion.
- Skin Sagging after zygoma reduction
Many people are afraid of skin sagging after zygoma reduction.
But if the patients are young and doctor dissect minimally, skin
sagging is not happened.
