An 18-year-old male was referred to the dentistry and oral surgery department with
a swelling of the left mandibular region. Extraoral examination revealed a swelling
at the left mandibular angle without tenderness or numbness. No cervical lymphadenopathy
or trismus was observed. Intraoral examination showed a slight swelling of the left
retromolar gingiva. A panoramic radiograph revealed a well-circumscribed, extensive
monocular radiolucency extending from the posterior body to the subcondylar region
of the mandible, involving the crown of the impacted third molar (Figure 1A). Computed tomography (CT) added the findings of buccolingual enlargement of the
lesion, and iso-dense to muscle tissue lumen (Figure 1B). CT also showed a highly compressed left mandibular canal (Figure 1C). After confirming the lesion was lined with slightly keratinized stratified squamous
epithelium without cellular atypia by histopathological examination (Figure 1D), he underwent surgical removal of the lesion and involved third molar extraction
under general anesthesia. The final diagnosis was a dentigerous cyst. Eighteen months
after surgery, a panoramic radiograph showed adequate bone regeneration (Figure 1E). No paresthesia of the left mental region was observed. At 3 years follow-up, the
patient remained disease-free.
