Characteristics of Maxillary Sinus Septa: A Cone-Beam Computed Tomography Evaluation

Area of Science:

• Dentistry
• Radiology
• Anatomy

Background:

• Maxillary sinus septa are bony formations within the maxillary sinus.
• Their prevalence and morphology can impact dental procedures.
• Cone-beam computed tomography (CBCT) provides detailed imaging of the maxillofacial region.

Purpose of the Study:

• To determine the prevalence, location, and morphological characteristics of maxillary sinus septa.
• To evaluate differences in septa based on gender.
• To assess the utility of CBCT in visualizing these structures.

Main Methods:

• Retrospective analysis of CBCT examinations from 200 patients.
• Evaluation of images in sagittal, coronal, and axial planes.
• Statistical analysis of septal prevalence, location, and morphology, with gender comparison.

Main Results:

• 122 out of 200 patients (61%) exhibited one or more maxillary sinus septa.
• Septal location and angulation showed no specific limitations.
• Significant gender-based differences in septa were observed.

Conclusions:

• CBCT imaging is valuable for detailed assessment of maxillary sinus septa.
• Understanding septal variations is crucial for planning sinus-related surgical procedures.
• CBCT offers advantages over conventional 2D radiography for evaluating sinus anatomy.
