<What is a long face?>
Normally, the length of the face is 1.3 times the width of the face. A long face refers to cases where the face is much longer than this norm.
While
a long face may be attributable to the width of the face being too narrow, it
is attributable to the length of the face being too long and therefore
diagnosed as a ‘long face’ in most cases.
In
cases of a long face, patients may not be able to fully close their mouth
during their ordinary day to day life, and their upper teeth and gum maybe
overly visible when smiling or laughing.
Moreover,
they experience teeth malocclusion with having open bite in often cases.
Maxilla (upper jaw)
A surgery
decision is selectively made on maxilla, based on the status of the long face.
In
case the face is insufficiently sized forward and backward due to excessive
delay in growth,
in
case vertical height is abnormal, and
in
case there is excessive facial asymmetry,
the
maxilla is cut horizontally in most cases and then re-positioned to the desired
location.
Mandible (lower jaw)
SSRO
or IVRO
Depending
on the patient symptoms, the most appropriate method between IVRO and SSRO is
chosen and used.
Chin (the edge of the jaw)
If the
length of the face is long primarily due to overly developed lower jaw, then
surgery is performed to shorten the length by cutting only the chin.
