“…With regard to the number of septa, 34.5% of the cases studied by us had one septum; 27.5%, two septa; 8%, three septa; 0.5%, four septa; and 1.5%, five septa. Our results are in accordance with a similar report that 71% of the edentulous patients, as well as 66% of the toothed patients, had at least one septum [18].…”

“…Another factor that contributed to the sample loss was the inclusion criteria. These factors certainly decreased the discriminating power of the study; however, based on other studies, it seems that the sample size was adequate, if certain criteria are observed.…”

Objective: To analyse the number of septa in the maxillary sinuses using computed tomography (CT) in correlation with gender, age and the presence of teeth in the region. Materials and methods: The sample consisted of 300 CT scans obtained from a private radiology clinic between 2009 and 2011. The CT scans included in the study should have the appropriate image of the maxillary sinus and contain information regarding age, gender and the date of the examinations. Patients with a history of pathologies in the region, patients who underwent floor of mouth surgery and patients less than 20 years of age were excluded from the sample. The authors considered osseous septa to be septa with a height above 4 mm in relation to the base of the sinus floor. The sample was divided into three groups: (i) presence of all teeth, (ii) partially edentulous -a minimum of two teeth present between the second premolar and second molar -and (iii) totally edentulous. The data were divided and stratified by age and gender. Results: The frequency of septa in the maxillary sinus was 37.80% (n = 183). No significant difference was observed among the five age groups (P > 0.05); additionally, there was no significant difference in septa frequency (P > 0.05) -analysis of variance (ANOVA), Tukey's. Univariate and multivariate ANOVA showed a significant interaction between tooth loss and age (P < 0.05). Conclusion: Statistical analyses demonstrated no difference in the number of septa in relation to age, gender or the number of teeth in the posterior maxilla. Clinical relevanceAfter tooth loss, the posterior maxillary alveolar bone suffers intense resorption and pneumatization of the maxillary sinus. These events reduce the available volume of the bone conventional dental implants fixation. Several surgical techniques are used in accessing the sinus floor to increase the membrane and attach the implant. The presence of bony septa increases the risk of surgical complications and requires surgical experience from the professional. This article evaluated the frequency of septa in 300 computed tomography scans, correlating gender, age and presence or not of teeth. It was concluded that the frequency of the septa is high and no correlation was found.

“…14 While previous studies have evaluated the anatomical structures and variations of the maxillary sinus, to our knowledge this is the first study evaluating whether or not a relation exists among the anatomical variations of the maxillary sinus; Underwood's septa, schneiderian membrane thickness, and the cortical thickness of the inferior border of the maxillary sinus. [17][18][19][20] According to Vlasiss and Fugazzotto, 21 perforation occurs more frequently during osteotomy than during the reflection of the membrane. 1,4,5,15,16 It is reported that the prevalence of antral septa varies between 13 and 35.3% in studies based on the number of sinuses, and between 21.6 and 66.7% in studies based on the number of patients.…”
