Axial Triangle of the Maxillary Sinus, and its Surgical Implication With the Position of Maxillary Sinus Septa During Sinus Floor Elevation: A CBCT Analysis

Research trends on maxillary sinus septa in 2019-2021: a scoping review with scientometric analysis

PURPOSE

This study aimed to conduct a bibliometric analysis of trends in the description items within the literature published from 2019 to 2021 with "maxillary sinus septum" in the title or subtitle.

METHODS

Electronic data from PubMed (MEDLINE), Google Scholar, and ScienceDirect were searched from 2019 to 2021. We used the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) to select 21 of 243 articles and examined their studies. Statistical calculations from data recorded by the authors were performed using the Chi-square, Mann-Whitney, and independent tests. Significance was set at P < 0.05.

RESULTS

The number of articles decreased annually. The highest number of publications was from Asia (64.3%), accounting for 71.4% of publications. The features of the septum were described for eight items, with one septum (70.14%) mentioned significantly more frequently, followed by on one side (65.89%) or the right side (62.22%). Location was mentioned significantly more frequently in the middle (55.22%) and for those aged 45 years and older (50.38%). No significant differences were observed in prevalence, age, height, or width between sexes; the patients' ages ranged from 18 to 90 years. Septa were significantly more prevalent in dentulous (45.38%) and partially edentulous (48.58%) patients, with significantly more patients exhibiting buccopalatal orientation (82.39%).

CONCLUSIONS

This study focused primarily on anatomical features using CBCT examination, and analyses of male-female differences and the origin of the sinus septum are necessary for the future.

Prevalence and Characteristics of the Maxillary Sinus Septa in a Saudi Arabian Sub-population: A Retrospective Cone Beam Computed Tomography (CBCT)-Based Study

OBJECTIVES

This study aims to investigate and determine the prevalence, location, and morphological differences of the maxillary sinus septa using cone beam computed tomography (CBCT) images in the Madina region and to discuss its clinical implications during sinus surgery.

METHODS

This study was a retrospective cross-sectional radiographic analysis of 808 CBCT scans from patients who attended Taibah University's College of Dentistry between December 2018 and June 2023. Age, gender, number of septa present per side, location (anterior, middle, posterior), morphology (complete or partial), and type (primary or secondary) were among the study variables. For data statistics, correlation analysis was utilized.  Results: Eight hundred eight CBCT scans were included with a mean age of 34.7±15.08. Septal bone was absent in 60.64% of the sinuses examined. Single septa were more common than multiple septa (p=0.009). Bilateral septal presence and the left septal bone were more common than the right, but none of these distributions were statistically significant. Males showed more sinus septa compared to females, but the difference was not statistically significant (p=0.420). Single septa were more prevalent in people under the age of 25.

CONCLUSION

More than 60% of the Madina population had patent sinus cavities with no septal processes, but males with single septal processes predominated.

Incidence, Size and Orientation of Maxillary Sinus Septa—A Retrospective Clinical Study

Background: The purpose of this study is to analyze if there is any statistical correlation between the surgery’s complexity (easy to difficult—depending on the anatomical conditions) and the patient’s sex, type of edentulism, and left or right side of the maxilla. Methods: Cone beam computed tomography records of 1192 maxillary sinuses were evaluated, measured, and statistically analyzed with respect to patient sex, type of edentulism, and left or right side, taking into consideration Wen’s proposed sinus septum classification. Results: Our research suggests that most sinus augmentation procedures in patients presenting antral septum fall into the Moderate A category (31.94%) and that there is not a correlation between the surgery’s complexity (easy to difficult) and the patient’s sex, type of edentulism and left or right side of the maxilla. Conclusion: We suggest a minor modification to Wen’s classification in view of the fact that our findings revealed a combination of medio-lateral and antero-posterior septa that we could not classify in one of the existing categories.
