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 may be
overly visible when smiling or laughing.
Moreover,
they experience teeth malocclusion with having openbite in often cases.
Long face surgical method
The
surgical method to treat and correct a long narrow face depends on the underlying
issues of the face.
If
the jaw is simply protruded or only the chi) is just long in length, the chin
only can be cut to correct. However, this must be proceeded with caution as the
face may look unnatural after cutting the chin only.
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.
