Hypertrophy of the coronoid process is associated with limitations in mandibular movement, and coronoidectomy is considered the treatment of choice.
Lower jaw with an outer row of enlarged curved spaced canines from symphysis to bend of dentary and directed somewhat anterodorsally, 1-2 irregular inner rows of smaller curved teeth at symphysis grading to a single row laterally and continuing to mid-height of coronoid process of dentary.
Five QTLs are significantly associated with the coronoid process (QTMAN3-2, QTMAN4-2, QTMAN13-1, QTMAN15-3, and QTMAN19-1), four with the condyloid process (QTMAN1-1, QTMAN9-1, QTMAN10-2, and QTMAN15-2), one with the angular process (QTMAN17-2), and three with the masseteric region (QTMAN1-1, QTMAN4-2, and QTMAN19-1).
The shape changes between the sexes were recorded in the form of canines and carnassials, and significant changes were in the shape of the coronoid process, angular process and masseteric fossa (LM 5, 8, 9).
The common sites for ectopic tooth are floor of nasal cavity, palate, coronoid process and mandibular condyle.
The coronoid process usually fractures in high energy trauma of the elbow (within the "terrible triad" of posterolateral dislocation, radial head, and coronoid fracture) [1-3].
The syndrome of "terrible triad of the elbow" is a severe pattern of injury that consists of an ulnohumeral dislocation associated with the fractures of the radial head and the coronoid process of the ulna (1) (Fig.
The advantage of this position over the previous positions is that both the radial head and coronoid process can be visualized by taking 2 projections angled 45[degrees] contralaterally; 1 mediolateral projection is taken for the radial head and 1 lateromedial projection for the coronoid process.

The temporal muscle (Fig 1d) originating from the temporal fossa was a poor muscle according to the masseter muscle and surrounded the coronoid process laterally and medially.
Description--The left lower jaw (TERA-154; Table 1) is missing the anterior portion of the ascending ramus, coronoid process, and condyloid process (Figs.
