Dissection of left temporal region

Anterior deep temporal artery, anterolateral view

The coronoid process of the mandible (17) has been cut away. The temporal muscle has been detached from its origin and reflected posterolaterally. Fat within the anterior part of the temporal fossa has been removed. The buccal fat pad seen previously was continuous with this fat.
