| The surgery
method of combining upper and
lower bone reduction is the integration
of the zygoma and mandible reductions.
They are the same from the technical
aspect point of view; however
before surgery the relative position
and the new shape of face after
receding zygomas and the mandible
at the same time must be considered.
Before the surgery, this must
be precisely calculated and evaluated
through X ray in order to complete
this surgery step by step.
Usually the width of the zygoma
decides the position of mandible,
therefore the zygoma located
on upper face would be the area
firstly to carry out the bone
reduction process. The mandible
reduction will be carried out
next after the zygoma reduction
is completed. This entire process
approximately takes 4~5 hours,
also as the surgery length is
longer, after the surgery, patient
must remain at the hospital
for one night for further observation
of each recovery conditions.
The drainage tube inside the
mouth will be removed the next
day before leaving the hospital.
After the surgery, patients
can only eat fluid food within
the first 2 weeks; verbal expression
will not be affected. Moreover,
after the surgery, in 1~2 months,
patient must wear a head cover
if possible to help to reduce
the swollenness and prevent
loosing or sagging of the skin
on the cheeks.
