Dentistry · Oral and maxillofacial surgery: common sites of mandibular fracture

Sample item

In an adult assault victim, which sites are the most commonly fractured parts of the mandible?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Condyle, angle and parasymphysis

The condylar neck, angle and parasymphyseal region are structurally weak points. Coronoid fractures are rare because of the protection by the zygomatic arch.

Option by option

  • A. Coronoid process and ramus

    The coronoid and ramus are infrequently fractured.

  • B. Condyle, angle and parasymphysis (correct)

    Correct. These are the commonest mandibular fracture sites.

  • C. Alveolar process only

    Alveolar fractures are less common and are usually associated with dental trauma.

  • D. Mental protuberance only

    Fractures of the chin point alone are not the most frequent.
