DentaCT for evaluating mandibular and maxillary invasion in cancer of the oral cavity.
We used a retrospective analysis of charts, imaging studies, and histologic findings when available in 17 patients with cancer of the oral cavity to define the value of DentaCT or multiplanar reformation software in assessing bony involvement by malignant tumors of the oral cavity. From two academic tertiary-referral medical centers, the 17 patients had a mean age of 63 years and suspected maxillary (2) or mandibular (15) invasion. All patients had conventional computed tomography scanning and multiplanar reformation scans with several additional imaging studies obtained. Two patients demonstrated no bony involvement by imaging and histologic studies. Twelve of the remaining 15 patients had surgically documented bony involvement also correctly detected by DentaCT. DentaCT was found to be a valuable tool in defining extent of bony invasion by tumor. Although not compared to other imaging modalities, our experience supports the use of DentaCT where available for this purpose.
