53Temporal, Infratemporal, And Pterygopalatine Fossae

Front 1

TMJ:
Because of the close relationship of the ___ nerves to the TMJ, care must be taken during surgical procedures to preserve both the branches of the facial nerve overlying it and the articular branches of the auriculotemporal nerve that enter the posterior part of the joint.

The TMJ may suffer from ___.

Abnormal function of the TMJ may result in structural problems such as ___ that results from delayed articular disc movement then sudden movement of the disc during opening and closing of the mandible.

Back 1

-facial and auriculotemporal nn.
-degenerative arthritis
-joint clicking and popping

Front 2

These veins do not have valves and thus an infection of the orbit or infratemporal fossa may enter the cranial cavity.

Back 2

Inferior ophthalmic v.  emissary vv.  pterygoid plexus (infratemp fossa)  cavernous sinus

Front 3

Jaw dislocation:

Jaw dislocation sometimes occurs when the mandible is ___. In this movement the head of the mandible and the disc both move forward until they reach the summit of the tubercle. In this position the joint is unstable and a minor blow on the chin, or a yawn, may pull the disc forward past the summit. In bilateral cases the mouth is held open and the heads of the mandible lie in front of the ___.
Reduction of the joint is achieved by pushing down on the lower ___ and pushing the jaw backwards.

Injury of the ___ nerve is associated with traumatic dislocation and rupture of the articular capsule and lateral ligaments.
