[Tomography of the maxillary sinus]

Area of Science:

• Radiology
• Anatomy
• Medical Imaging

Background:

• Maxillary sinus anatomy is crucial for diagnosing various pathologies.
• Conventional roentgenography has limitations in visualizing detailed sinus wall structures.
• Tomography offers potential advantages for detailed anatomical assessment.

Purpose of the Study:

• To investigate the roentgen-anatomical features of the maxillary sinuses using tomography.
• To compare tomographic imaging with conventional roentgenography for sinus visualization.
• To describe the laminar picture of the maxillary sinuses in different projections.

Main Methods:

• Roentgenographic and tomographic studies were performed on 108 patients with intact maxillary sinuses.
• Anatomical preparations of 16 crania were also utilized for detailed examination.
• Standard naso-frontal, nasomental, and lateral projections were employed.

Main Results:

• Tomography effectively visualizes maxillary sinus osseous walls by leveraging oblique ray beam angles.
• Specific wall sections disappear when significantly inclined relative to the roentgen film plane.
• Distinct laminar picture types were identified in each projection, correlating with sinus section depth.

Conclusions:

• Tomography provides superior visualization of maxillary sinus laminar features compared to conventional methods.
• The described tomographic projections and laminar types aid in detailed anatomical interpretation.
• This method enhances the understanding of maxillary sinus morphology and depth variations.
