“…This was in agreement with several other studies; for example, Furtado and his colleagues found the highest percentage of septa to be in the middle sinus region (44.2%) (45), while Toprac and Atac found it was 59.62% (43), and the Orhan group reported 69.1% (37). Meanwhile, contradictory results were also reported by Schriber and his group, who found the majority of septa to be located in the posterior maxilla in the region of the second molars (47), whereas Shahidi et al found most septa were in the anterior region (Shahidi et al 2016) and (48) reported no signi cant difference among the locations of septal occurrence in the anteroposterior plane (48).…”

“…Other investigators presented a more speci c estimate for the percentage of septa among patients and sinuses; for example, Bornstein and colleagues found septa to be present in 66.5% of patients and 56.5% of all evaluated sinuses (42). Another study found septa in 44% of the patients and approximately 31.17% of the sinuses (43). In a recent meta-analysis, the mean prevalence of septa per patient was 41%, while the prevalence by sinus was 33% (44).…”

“…In a recent meta-analysis, the mean prevalence of septa per patient was 41%, while the prevalence by sinus was 33% (44). The variability among the percentages reported can be attributed to the differences in patient samples, including their age and ethnicity; the use of various evaluation methods, such as cadaveric dissection, surgical evaluation, and radiographic examination; differences in the types of radiographs selected (2-D versus 3-D); as well as the variability of the septal inclusion criteria (i.e., the minimal height and thickness for their identi cation) (43,44). Our study found septa occurred in approximately 45% of the evaluated patients and approximately 30% of the evaluated sinuses, which is in line with the previous studies.…”

Again, these variations can be explained by the differences in the studied populations, where age groups and sequence of dental extractions can vary, affecting the pneumatization (43).…”

Background The variability in the maxillary sinus anatomy makes dental implant planning challenging. One of the anatomical landmarks that could affect the decision for implant placement around the maxillary sinus is the sinus septa. This study aimed to retrospectively determine the prevalence, anatomical distribution, and morphology of the maxillary sinus septa. Materials and methods This study included 309 CBCT images that were analyzed to determine the prevalence, height, location, and orientation of the maxillary sinus septa. Descriptive statistics, Mann‒Whitney U tests, and Kruskal‒Wallis tests were used for data analysis. Results A total of 618 maxillary sinuses were analyzed. Maxillary septa were present in 30% (n = 188) of the sinuses and in approximately 45% of the analyzed images. The mean height of the septa was 5.09 mm. The presence of bilateral septa was evident in 49 subjects (35.25%). Female subjects were significantly more likely to have only one septum (n = 67, 53.6%, p < 0.05). Conclusion The presence of septa is very common, found in one-third to approximately half of the evaluated cases, which warrants careful examination before any surgical interventions to avoid possible complications.

“…12 The quantity, location, and heights of sinus septa were different in person. 13 When it is located in a molar position, membrane perforation was most likely to occur. 14 Membrane thickness has also been demonstrated as a key factor influencing membrane tearing and subsequent implant failure.…”

Objective To estimate the association between smoking and Schneiderian membrane perforation in sinus floor augmentation. Materials and methods Searches were conducted in PubMed, Web of Science, Embase, and Cochrane Library. Data were extracted by two authors independently. The inclusion criteria were the (1) age of patients >18, (2) the number of participants >10, and (3) smoking and the patients of Schneiderian membrane perforation were accurately recorded. The risk of bias was assessed by the Newcastle–Ottawa scale (NOS). Statistics analyses were conducted using Reman5.4.1 and Stata (15.0). The association of Schneiderian membrane perforation with smoking habits during maxillary sinus floor elevation was expressed as odds ratios (ORs) with a 95% confidence interval (95% CIs). And the I2 statistic was used to estimate statistical heterogeneity. The funnel plot and Egger's tests were used to evaluate the reliability and stability of the results. Results Of 1463 articles screened, nine studies were included in our systematic review, and eight were synthesized for meta‐analysis. Eight were retrospective observational studies and one was a clinical trial, with a total of 1424 patients included. The nine studies were proved as high quality according to the NOS. There was no significant publication bias in the studies (p = 0.827). A random‐effects model was used because of differences in the adopted methodologies (p = 0.39, I2 = 5%). During maxillary sinus augmentation, smoking and Schneiderian membrane perforation were associated (odds ratios, 1.58 [95% CI, 1.10–2.25]). Conclusion Smoking increased the risk of membrane perforation in maxillary sinus floor augmentation. Our evaluation was limited by the poor reporting of the number of cigarettes smoked per day (PROSPERO number was CRD42022306570).
