“…In our study, 33 septa were incorporated into the sinus lift as one border of it. We did not find radiological signs of sinus membrane perforations, such as dissemination of biomaterials or opacificiation of the sinus, which reinforces that employing 3D CBCT scan before sinus lift surgery reduces complications (Maestre-Ferrin et al, 2010;Maestre-Ferrin et al, 2011;Dragan et al, 2017).…”

Sinus lift surgery elevation is a procedure that requires radiological maxillary sinus evaluation and procedure planning. The condition of the maxillary sinus before and after sinus lift surgery was assessed. Sixty-five sinuses of 49 patients were included in the study. Preoperative and postoperative cone beam computed tomography (CBCT) scans were performed. The sinuses were analysed radiologically for pathological changes: mucosal thickening, ostia obstruction and accessory opening. The presence of concha bullosa in nasal cavity and septa in the maxillary sinus were recorded. The sinus volume also was measured before and after surgery. Thickened mucosa was found more often in postoperative scans than in preoperative scans (63.1% and 67.7%, respectively). Concha bullosa was found in 30 preoperative scans and in 33 postoperative scans. A correlation between mucosal thickening and ostia obstruction was found. The mean sinus volume decreased after surgery and the changes were statistically significant. In conclusion, changes of the maxillarysinus and nasal cavity can be detected with CBCT. Sinus lift surgery does not excacerebate the existing conditions of the maxillary sinus; however, there is a tendency for pathological features to increase after surgery. Sinus lift surgery is a safe surgery with regard to the maxillary sinus if performed with care.

“…The CBCT investigation helps to plan sinus lift surgery with the fewest complications. Meanwhile, the sinus septa can be used as an alternative location for implant placement (Dragan et al, 2017). In our study, 33 septa were incorporated into the sinus lift as one border of it.…”

“…An edentulous posterior maxilla with severe bone resorption and sinus pneumatization requires bone augmentation prior to implant placement in order to increase the success rate of treatment with implants%Sinus floor augmentation in partially or fully edentulous patients is performed via different surgical techniques prior to implant placement. 2 In adults, the maxillary sinuses are pyramid-shaped; the base of the pyramid is the lateral nasal wall while the tip of the pyramid is the zygomatic process of the maxilla. 3 After tooth extraction, resorption of the alveolar process occurs.…”

This study sought to assess the internal anatomy of the maxillary sinuses and their septa using cone-beam computed tomography (CBCT) in an Iranian population. Materials and Methods: Resorption of alveolar bone decreases the height of the maxillary alveolar ridge. This height reduction may be so severe that it warrants ridge augmentation by a sinus lift. Manipulation of the maxillary sinuses, as in sinus lift surgery, requires adequate knowledge about the sinus anatomy. Results: Maxillary sinus septum, as an anatomical variation, may complicate the surgical procedures and increase the risk of complications such as sinus membrane perforation. In this retrospective study, 366 sinuses, 190 from females and 176 from males, aged between 10 and 65 years old presenting to the Oral and Maxillofacial Radiology Department of School of Dentistry at Hamadan University of Medical Sciences were evaluated by two oral radiologists. The extension of the maxillary sinuses, presence of septa, number of septa and their location were determined. Data were analyzed using the chi square test (level of significance p≤0.001). The coefficient of agreement between the two oral radiologists was calculated based on Cohen kappa. Septa were present in 40.5% of the maxillary sinuses, out of which, 31.6% had one, 7.9% had two and 1% had three or more septa; 38% of the septa were horizontal while 62% had an oblique orientation. In total, 184 septa were found in 183 patients; out of which, 91 septa were 2 to 5 mm long while 93 septa were longer than 5mm. Conclusions: Comprehensive knowledge about the three-dimensional internal anatomy of the maxillary sinuses acquired by CBCT prior to surgical procedures can greatly help to prevent postoperative complications.

“…Several studies were conducted on height, location, prevalence, and morphology of the MSSs, in adult patients, using various medical imaging techniques such as CBCT (9). The angle between the septum and the median palatine suture was also assessed by some authors (10,11).…”

Aim: The aim of the study was to examine the prevalence of maxillary sinus septa (MSS) in a Turkish population, using cone-beam computed tomography (CBCT).  Methodology: The CBCT images of 350 untreated patients (178 male, 172 female ranging in age between 18 and 65) were included in this study. The presence or absence of MSS was determined in axial, sagittal, and coronal planes by considering gender and side. For statistical evaluation, a chi‐square test was used to determine any differences in the prevalence of MSS with significance set at 5%. Results: MSSs were observed in 201 out of 700 sides (28.71%) and 141 out of 350 patients (40.28%), of which, 70 were in males and 71 in females. MSS were also observed in a higher prevalence on the bilateral side. (17.14%). Female patients showed higher prevalence (41.27%) than the male patients (39.32%). Conclusion: MSS was observed in 40.28% of examined Turkish subjects and detected more frequently in females and on the bilateral side. How to cite this article: Laçin N, İzol BS.
