Osteoid Osteoma of the Basilar Border of the Mandible: A Diagnostic Dilemma

Figure 1

Standard radiological assessment. (a) Initial panoramic radiograph showing superposition of the hyoid bone on the left mandibular basilar border (white dashed circle), masking the osteolytic image. (b) Panoramic radiograph repeated with the patient in a slightly hyperextended position, allowing a lower projection of the hyoid bone (dotted white arrow), and a good visualization of the osteolytic image of the left basilar border (white arrow). (c) Retroalveolar radiograph performed after extraction of the tooth #37 showing the healing alveolus of this tooth and an osteolytic image (white arrows) below the mandibular canal (black arrowheads) at the lower limit of the radiograph.
