Abstract

Background Oral squamous carcinoma (OSCC) is often diagnosed at late stages and bone erosion or invasion of the

jawbone is frequently present. Computed tomography (CT) and magnetic resonance imaging (MRI) are known to

have high diagnostic sensitivities, specificities, and accuracies in detecting these bone affections in patients suffering

from OSCC. To date, the existing data regarding the impact of cone-beam computed tomography (CBCT) have been

weak. Therefore, this study aimed to investigate whether CBCT is a suitable tool to detect bone erosion or invasion in

patients with OSCC.

Methods We investigated in a prospective trial the impact of CBCT in the diagnosis of bone erosion or invasion in

patients with OSCC who underwent surgery. Every participant received a CBCT, CT, and MRI scan during staging.

Imaging modalities were evaluated by two specialists in oral and maxillofacial surgery (CBCT) and two specialists

in radiology (CT and MRI) in a blinded way, to determine whether a bone affection was present or not. Reporting

used the following 3-point system: no bony destruction (“0”), cortical bone erosion (“1”), or medullary bone invasion

(“2”). Histological examination or a follow-up served to calculate the sensitivities, specificities, and accuracies of the

imaging modalities.

Results Our results revealed high diagnostic sensitivities (95.6%, 84.4%, and 88.9%), specificities (87.0%, 91.7%, and

91.7%), and accuracies (89.5%, 89.5%, and 90.8%) for CBCT, CT, and MRI. A pairwise comparison found no statistical

difference between CBCT, CT, and MRI.
