High resolution CT with image reformation in maxillofacial pathology

Area of Science:

• Radiology
• Maxillofacial Surgery
• Medical Imaging

Background:

• Maxillofacial pathology presents diagnostic challenges, often requiring advanced imaging for accurate assessment.
• Conventional imaging techniques may not provide sufficient detail for complex maxillofacial conditions.

Purpose of the Study:

• To evaluate the efficacy of computed tomography (CT) with multiplanar reformations in diagnosing complex maxillofacial pathology.
• To compare the diagnostic capabilities of CT with pluridirectional tomography in maxillofacial imaging.

Main Methods:

• Twenty-four patients with maxillofacial pathology underwent high-resolution CT with thin sections (1.5-5.0 mm) and multiplanar image reformation.
• Eight patients also had pluridirectional tomography for comparative analysis.
• Patient cohorts included facial trauma, acute paranasal sinus infections, and suspected neoplasms.

Main Results:

• CT accurately identified fracture sites and fragment relationships to vital structures in facial trauma, optimizing surgical planning.
• CT delineated the extent of infectious processes and neoplasms, guiding therapy and differentiating benign from malignant lesions.
• Density determination by CT distinguished neoplastic tissue from inspissated mucus in obstructed sinuses.

Conclusions:

• Computed tomography is the definitive imaging method for complex maxillofacial pathology, especially when plain films are insufficient.
• CT with multiplanar reformations provides superior evaluation compared to thin-section pluridirectional tomography in several cases.
• CT enables precise diagnosis, surgical planning, and therapeutic guidance for maxillofacial trauma, infections, and neoplasms.
