Lingual Lateral Canal Mimicking Mandible Fracture

Abstract

Lingual lateral canal is a rare variation in the trajectory of the mandibular canal, and is usually detected as an incidental finding on radiographic exams, especially on cone-beam computed tomography. Due to its radiographic characteristics, this anatomical variation might be confused with a mandible fracture. Therefore, the knowledge of its presence is essential not only to differentiate it from a fracture, but also for the success of surgical procedures performed in the mandible, making it easier to avoid clinical complications such as swelling, bruising, bleeding, and neurovascular disorders. This report shows the case of a lingual lateral canal mimicking a fracture on the mandibular body.
