CORONOID HYPERPLASIA:

CONDYLAR HYPERPLASIA:

BIFIDCONDYLE:

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.
