PURPOSE: The aim of the present study was to investigate whether a difference exists in the location of the displaced @entity133 ( @entity133 ) and neurovascular bundle (toward the buccal or lingual cortex) among odontogenic @entity5 and @entity455 . If some consistency exists in the manner in which the canal and bundle are displaced on radiographic examination, the nature of the mandibular lesion under examination could be anticipated. This information would assist the surgical team in treatment planning, diagnostic biopsy, and resection, especially in cases of intraosseous vascular pathologic findings. MATERIALS AND METHODS: A retrospective review of the computed tomography images obtained for odontogenic @entity5 and @entity455 treated at the Department of Oral and Maxillofacial Surgery, University of Illinois at Chicago, from January 2000 to June 2010 was undertaken. The @entity133 and neurovascular bundle were traced from the lingula to the mental foramina, and its location within the mandible was recorded at 3 specific points. RESULTS: In the odontogenic @entity5 group, we found that the canal with the neurovascular bundle was displaced either toward the buccal cortex of the mandible or the inferior border, but it was never identified lingually. In contrast, all the @entity455 had displaced the structures toward the lingual aspect of the mandible at all selected points. CONCLUSIONS: To our knowledge, this is the first study to have examined the potential differences in the displacement of the @entity531 bundle caused by the 2 commonly encountered pathologic entities in the maxillofacial skeleton: odontogenic @entity5 and @entity455 . We identified a striking difference in the manner of the @entity133 and its contents that was consistent among the @entity5 in the 2 groups. The location of the @entity133 in relationship to the pathologic entity under investigation could prove valuable in the differential diagnosis and assist with planning the biopsy. Additional investigation with a larger number of cases of these 2 groups of lesions involving the mandible is warranted to confirm our preliminary findings.

Does a difference exist in XXXX caused by commonly encountered pathologic entities? An observational study.
