“…The presence of septa was significantly higher in the middle region in both the right and left sinuses which is consistent with most of the previously reported data as reviewed by Malec et al 10 However, our results are inconsistent with Neychev et al, who found the septa to be more common in the anterior or posterior regions based on the dentate status. 30 The orientation of the majority of maxillary sinus septa in the current study were mediolateral, and the anteroposterior oriented septa were infrequent, which is also consistent with previous studies. 4,19,29,33 The prevalence of complete septa is rare and most if not all septa are partial.…”

“…However, it is important to note that Park et al 29 found the prevalence of septa to be higher among females and Neychev et al, found no correlation between gender and the presence of septa. 30 Previous studies have found that there was a positive association between age and the presence of septa. This was also true in the current findings, where 7.3% were found in patients who were younger than 25 years of age versus 61.4% in patients who were 45 years or older.…”

Prevalence and morphological variations of maxillary sinus septa in different age groups: a CBCT analysis BACKGROUND: There are limited data from Saudi Arabia on the prevalence and characteristics of maxillary sinus septa. OBJECTIVE: Determine the prevalence and morphological characteristics of septa in the maxillary sinus and their relationship to gender and age using cone beam computed tomography (CBCT). DESIGN: Cross-sectional SETTING: CBCT images acquired from the maxillofacial radiology department in a dental school. PATIENT AND METHODS: CBCT scans of 1010 maxillary sinuses from 505 patients were analyzed to determine the prevalence, location, type, and orientation of maxillary sinus septa. Descriptive statistics, chisquare tests and t tests were used to analyze the data. MAIN OUTCOME MEASURES: The prevalence, location, type, and orientation of maxillary sinus septa. SAMPLE SIZE: 1010 sinuses from 505 patients. RESULT: Approximately 46% of the studied patients had maxillary septa, which were present in 370 (37%) sinuses. About 64% of the septa were present on the right side and 85.7% of all septa were mediolaterally oriented. The mean height of the septa was 6.06 mm (0.84) in the right sinuses and 5.70 mm (0.93) in the left sinuses. Multiple septa were found in 101 patients (20%). Among males, 58.5% had septa compared to 34% of females (P<.001.) A significant positive association was found between age and the presence and number of septa, P<.001. CONCLUSIONS: Maxillary sinus septa were highly prevalent with various heights and directions among the studied sample. Careful assessment of different anatomic variation must be conducted prior to any maxillary sinus augmentation, particularly in older patients. LIMITATIONS: Cross-sectional evaluation of CBCT images from one dental school patient population; thus, the findings cannot be generalized to other populations. CONFLICT OF INTEREST: None.

“…We also investigated the type of septa and assessed the relationship between tooth loss, infundibulum length, and ostium height. Neychev et al [29] reported that primary complete septa were found in patients with teeth, and secondary partial septa were observed in edentulous patients; in our study, the edentulous patients were found to have a higher prevalence of septa. Our results showed a statistically significant difference between the septa type in toothed and edentulous regions of the maxilla.…”

“…Maxillary sinus septa is one of the most studied subjects in terms of location, prevalence, and morphology [27][28][29]. Maxillary sinus septa was found in 49% of patients, on the right (40.2%) and left (33.4%) sides, higher than reported by Kim et al [27], Neugebauer et al [28], but lower than reported by Neychev et al [29]. This difference could be associated with the different radiograph-DOI: 10.1159/000504963 ic examinations, the thin interval slice of the CBCT images (in this study, 0.2-0.4 mm), and the different ages of the study populations.…”

Objective: The aim of this study was to evaluate the correlation between the length of the infundibulum and ostium height with the anatomic variations of osteomeatal complex (OMC) and sinus pathology using cone-beam computed tomography (CBCT). Methods: CBCT images of 204 patients (408 maxillary sinuses) were evaluated retrospectively. The height of the ostium and the length of the infundibulum were measured. The presence of maxillary sinus pathology, nasal septal deviation, Haller cells, concha bullosa, and sinus septa were analyzed. The correlation between the size of the maxillary sinus drainage system and anatomic variations was compared using the t test, Fisher’s exact test, and χ² test. The effect of tooth loss on the length of the infundibulum and ostium height was also analyzed using ANOVA. Results: The height of the ostium and the maximal septal deviation angle were found to be significantly greater in males (p < 0.05). As ostium height increased, the presence of maxillary sinus septa increased (p < 0.05). No statistically significant association was detected between other variations and the length of infundibulum or ostium height. The relationship between tooth loss and both the length of the infundibulum and ostium height were found to be insignificant (p > 0.05). Conclusions: Radiographic examination, especially on CBCT images, is important for an evaluation of maxillary sinuses. here, we demonstrated a significant relationship between ostium height and the presence of maxillary sinus septa. However, it was found that nasal septal deviation, concha bullosa, Haller cells, and other sinusopathies did not have a major effect on the size of the maxillary sinus drainage system.

Cone-beam computed tomographic analysis of maxillary sinus septa among Yemeni population: a cross-sectional study

Background Maxillary sinus septa increase perforation risk of Schneiderian membrane during the sinus floor elevation (SFE). Cone Beam Computed Tomography (CBCT) allows for a more precise assessment of the septal position; thus, preoperative CBCT analysis is substantial to avoid possible complications. This study aims to investigate the 3D characteristics of the maxillary sinus septa based on CBCT images. To our knowledge, no study reported the CBCT-based investigation for the sinus septa among Yemeni population. Materials and methods This is a retrospective cross-sectional analysis of 880 sinus CBCT images 440 patients. The septa prevalence, locations, orientations, morphology, and associated factors were analyzed. The effect of age, gender, and dental status on the sinus septa and the relationship between sinus membrane pathology and sinus septa were also analyzed. Anatomage (Invivo version 6) was used for CBCT images analysis. Descriptive and analytical statistics were performed, and a P-value < 0.05 was significantly considered. Results The maxillary sinus septa were found among 63.9% of patients and 47% of sinuses. The average septa height was 5.2 mm. 15.7% of patients had septa in the right maxilla, 18% in the left, and 30.2% in both. Gender, age, and dental condition had no influence on the presence of septa, and septa presence did not influence sinus membrane pathology. Many septa originated from the floor (54.5%), located in the middle (43%), with coronal orientation (66%) and complete configuration (58.2%). Conclusion Based on our findings, the septa prevalence, locations, orientations, and morphology were significant and equivalent to the highest recorded in the literature yet. Thus, when sinus floor elevation is planned, CBCT imaging of the maxillary sinus is recommended for safe dental implantation.
