ABSTRACT
Introduction
:
Surgeries
in
the
paraclinoid
region
for
the
clinoid
segment
of
internal
carotid
artery,
periclinoid
tumours,
lesions
of
anterior
part
of
cavernous
sinus
and
traumatic
optic
neuropathy
require
the
removal
of
anterior
clinoid
process
to
increase
the
accessibility
to
the
important
structures
in
the
region.
Anterior
clinoidectomy
is
a
critical
and
important
procedure
and
requires
utmost
knowledge
of
the
morphometry
of
anterior
clinoid
process.
So,
this
study
was undertaken to record the morphometry of anterior clinoid process (ACP).
Materials
and
Methods:
Fifty
formalin-fixed
cadavers
were
utilized
from
a
medical
college
in
Mumbai,
Maharashtra.
The
measurements
were
done
bilaterally
after
removal
of
the
brain
and
meticulous
dissection
of
cranial
fossae
was
done
to
reflect
the
duramater,
nerves,
vessels
and
other
structures
from the field of measurement.
Results
:
The
mean
distance
between
the
tip
of
ACP
and
medial
margin
of
the
optic
canal
on
the
right
side
was
11.5
mm
and
on
the
left
side
was
11.6
mm;
the
mean
distance
between
the
tip
of
ACP
and
lateral
margin
of
the
optic
canal
on
the
right
side
was
5.4
mm
and
on
the
left
side
was
5.4
mm;
the
mean
distance
between
medial
margin
of
the
optic
canal
and
the
lateral
edge
of
ACP
on
the
right
side
was
14.3
mm
and
on
the
left
side
was
14.2
mm;
the
mean
distance
between
the
lateral
margin
of
the
optic
canal
and
the
lateral
edge
of
ACP
on
the
right
side
was
3.3
mm
and
on
the
left
side
was
3.4
mm;
the
mean
distance
between
the
tip
of
ACP
and
the
tip
of
posterior
clinoid
process
(PCP)
on
the
right
side
was
4.2
mm
and
on
the
left
side
was
4.3
mm;
the
mean
distance
between
the
tips
of
ACP
was
22.8
mm;
the
mean
distance
between
the
ACPs
at
the
level
of
lateral
margin
of
the
optic
canal
was
23.9
mm;
the
mean
distance
between
the
ACPs
at
the
level
of
medial
margin
of
the
optic
canal
was
12.3
mm
and
mean
vertical
dimension
of
the
ACP
at
the
level
of
lateral
margin
of
optic
canal
was
2.4
mm.
Conclusion
:
The
findings
of
the
present
study
will
help
the
surgeons
in
surgeries
of
the
cavernous
sinus
and
paraclinoid region requiring anterior clinoidectomy.
