Structures of the midface on cylindrical pantomograms.

Area of Science:

• Radiology
• Anatomy
• Medical Imaging

Background:

• Cylindrical pantomography offers advanced visualization of facial structures.
• Previous research identified optimal projection parameters for pantomograms.

Purpose of the Study:

• To present anatomical structures of the middle third of the face using optimized pantomographic projections.
• To evaluate the utility of new pantomographic equipment for diagnosing facial fractures.

Main Methods:

• Utilized prototype pantomographic equipment capable of orthopantomograms, concentric tomograms, and linear tomograms.
• Employed specific projection angles (e.g., 30-degree retroversion, 25-degree anteversion) and beam positioning relative to the Frankfort plane.
• Conducted experiments with corpses of road traffic victims to assess diagnostic capabilities for fractures.

Main Results:

• Optimized projections provide maximum information for visualizing the middle third of the face.
• The equipment is particularly useful for diagnosing fractures in the middle third of the face in trauma patients.
• Specific head tilts and beam positioning effectively shift cranial base shadows for clearer imaging.

Conclusions:

• The described pantomographic techniques and equipment enhance the diagnosis of middle third facial fractures.
• Optimized projections and artifact reduction methods improve the diagnostic accuracy of pantomography for facial trauma.
