Background and Objective: Today, implant-based treatments are used as a suitable alternative for toothless areas. Anatomical variations in the maxillary sinus region, including the presence of septa, interfere with implant placement in this area and can increase surgical complications, including perforation of the sinus membrane. This study was aimed at detecting the characteristics of maxillary sinus septa such as prevalence, location and direction in a sample of Mashhad population.
Methods: In this cross-sectional study, data were collected from patients of a private oral and maxillofacial radiology center in Mashhad who had referred for CBCT imaging within one year. CBCT images of 150 patients (61 males and 89 females) in the age range of 18 to 77 years were observed in three axial, coronal and sagittal views. Then, the frequency of data was recorded and analyzed based on septa observation, septa location, right and left side, dental status of the area, septa location direction, and maxillary sinus septa status.
Findings: In general, 119 (39.76%) septa were observed in 300 sinuses. On the right and left sides, 42.7% and 36.7% of the sinuses had septa, respectively. 42.7% of septa were on the right side and 36.7% were on the left side. There was no statistically significant difference between the two sides in terms of direction. The highest presence of septa was observed in the anterior regions (48.74%), followed by the posterior and middle regions (38.66% and 12.61%, respectively). There was a statistically significant difference in the distribution of septa frequency between regions (p<0.001). The anterior-posterior (sagittal) and mediolateral (transverse) directions were observed in 37 cases (28.46%) and 74 cases (56.92%), respectively. The most common direction of septa was transverse.
Conclusion: The findings of the present study showed that maxillary septa may be present in all regions and directions. |
