EXOSTOSES:
The histopathology of the torus mandibularis is similar to that
of other exostoses, consisting primarily of a nodular mass of
dense, cortical lamellar bone. An inner zone of trabecular bone
with associated fatty marrow sometimes is visible.
EAGLE SYNDROME:(STYLOHYOID SYNDROME; CAROTID
ARTERY SYNDROME):
• Elongation of the styloid process or
mineralization of the stylohyoid ligament
complex is not unusual having been reported in
18% to 40% of the population in some
radiographic reviews.
• Such mineralization is usually bilateral, but it
may affect only one side. Most cases are
asymptomatic ; however, a small number of such
patients experience symptoms of Eagle syndrome
caused by impingement or compression of
adjacent nerves or blood vessels.
