Fractured Mandible, Gross Anatomy

Description

Rendered in left lateral view of an adult male skull, the illustration centers on the mandible and the temporomandibular joint region, with a red-highlighted fracture involving the condylar process at the posterior-superior end of the mandibular ramus. Superior to the fractured condyle sit the temporal bone’s mandibular (glenoid) fossa and the articular eminence, while anterior to the ramus the coronoid process projects toward the zygomatic arch. Cranial sutures are clearly delineated across the calvaria, and the nasal bones are picked out in light blue at the anterior midface, providing orientation relative to the maxilla and the visible upper and lower dentition. Condylar fractures matter because they change mandibular mechanics at the TMJ, often producing posterior open bite on the injured side, contralateral premature contact, deviation of the chin toward the fracture with opening, and painful trismus from lateral pterygoid pull on the fractured segment. Small details at the condylar head and neck guide management. A high condylar neck fracture can be treated with closed reduction and maxillomandibular fixation in select cases, while displaced or dislocated condylar head injuries may push you toward open reduction and internal fixation, weighed against risks to the facial nerve during preauricular or retromandibular approaches. The lateral perspective also matches common trauma imaging logic, helping learners relate gross landmarks to panoramic radiography and CT reformats. Use this plate in dental and medical gross anatomy courses when teaching the mandible, TMJ anatomy, and dentoalveolar occlusion, or in oral and maxillofacial surgery and emergency medicine materials covering facial trauma patterns. It also suits journal figures and patient education handouts where a single, clean lateral view clarifies why a condylar fracture disrupts bite and jaw motion.
