Evaluation Of Morphology and Anatomy of the Nasopalatine Canal Using CBCT. A Retrospective Study

Abstract

Background

The nasopalatine canal (NPC) plays a crucial role in maxillary surgical and implant procedures. Cone-beam computed tomography (CBCT) provides precise three-dimensional imaging for evaluating its morphology and anatomical variations. This study aims to assess the morphological characteristics and dimensions of the NPC using CBCT in a retrospective dataset.

Materials and Methods: This retrospective study analyzed CBCT scans of 120 patients (60 males, 60 females) obtained from a dental radiology database. The NPC’s length, width, shape, and variations in anatomical morphology were evaluated using specialized imaging software. Statistical analysis was performed to compare differences based on gender and age groups.

Results:The mean length of the NPC was 13.5 ± 2.4 mm, and the average width at the nasal and oral openings was 3.8 ± 1.2 mm and 4.5 ± 1.1 mm, respectively. The most common canal shape observed was the cylindrical type (45%), followed by the funnel-shaped (30%) and hourglass-shaped (25%). Significant differences were noted in NPC dimensions between males and females (p < 0.05). Age-related changes in canal morphology were also observed, with a gradual increase in canal width in older age groups.

Conclusion: The study highlights the anatomical variations of the NPC, emphasizing the importance of CBCT in pre-surgical evaluation. The findings suggest that gender and age significantly influence NPC dimensions, which should be considered during surgical and implant planning to minimize complications.
