Management of vascular malformations of the parotid area
Résumé
Objectives:
To
describe
our
experience
in
the
management
of
vascular
malformations
of
the
parotid
area.
Materials
and
methods:
This
was
a
retrospective
study.
Among
614
parotidectomy
performed
between
1998
and
2008
at
our
institution,
10
cases
(1.6%)
of
vascular
malformations
have
been
identified.
Clinical
features
and
management
of
these
patients
were
analyzed.
Results:
Clinical
presentation
was
usually
related
to
that
of
a
benign,
slow-growing
and
asymp-
tomatic
tumor.
There
was
a
marked
female
predominance
(90%).
In
any
case,
the
diagnosis
of
vascular
malformation
could
be
obtained
with
certainty
preoperatively.
Surgical
excision
was
performed
most
often
referred
to
diagnosis.
Sixty
percent
of
vascular
malformations
were
located
in
the
superficial
lobe
of
the
parotid
gland.
On
the
histological
we
found
a
classic
look
with
benign
vascular
proliferation
of
endothelial
cells
in
the
walls.
The
vessel
lumen
was
either
the
head
of
a
congestion
or
thrombosis
or
calcification
(phleboliths).
Conclusion:
Vascular
malformations
of
the
parotid
gland,
rare
disease,
are
mainly
venous.
The
terminology
is
based
on
clinical
data,
scalable,
histological
and
hemodynamic
as
classified
by
the
International
Society
of
Study
of
Vascular
Anomaly
(ISSVA).
Despite
advances
in
imaging
including
MRI
they
remain
difficult
to
diagnose.
The
treatment
of
reference
is
surgical
excision.
