A comparative study of three imaging modalities currently used in the assessment of patients for maxillofacial surgery.
Diagnostic imaging is pivotal in clinical maxillofacial evaluation. This study evaluated and compared the use of conventional radiographs (CR) with two-dimensional (2D) and three-dimensional (3D) computed tomography (CT) in patients requiring maxillofacial surgery. Pre-surgical records of sixty five patients who had undergone routine CR, 2D CT and 3D CT were selected and classified into the categories of traumatic injury, pathology and deformities. The accuracy of image analysis, diagnosis and treatment planning were scored and the data statistically analysed. 2D CT scanning was more effective diagnostically and is preferred for cases of traumatic injury (44%, SD=0.54, p>0.05) and pathology (34%, SD=0.47, p>0.05) whilst 3D CT imaging was indicated for the deformity category (22%, SD=0.58, p>0.05). Linear comparisons between radiographic modalities within each clinical group revealed significant differences (p<0.05). Multiplanar reformatted (MPR) 2D cross sectional CT views offered additional imaging information.


CONCLUSIONS
2D CT scanning is an excellent imaging modality for the majority of craniomaxillofacial surgical cases. 3D CT scanning is also recommended for cases of trauma and pathology. Both 2D CT and 3D CT scanning are vital in craniomaxillofacial deformities and reconstructive surgery.
