“…Various studies were conducted on height, location, prevalence, and morphology of the maxillary sinus septa, in adult patients, using diverse medical imaging techniques such as cone beam computed tomography (CBCT) [26–34]. The measurements were performed in 2 dimensions (2D) in axial, sagittal, or panoramic images.…”

BackgroundThe aim of our study was to investigate, in 3 dimensions, the maxillary sinus septa as an alternative site for dental implant placement to avoid sinus lift procedures.Material/MethodsWe selected 100 dentate and 100 edentate patients with the presence of a maxillary sinus septum by reviewing a larger cone beam computer tomography (CBCT) database from the Department of Oral and Maxillofacial Surgery at Cliniques Universitaires Saint Luc in Bruxelles, Belgium.Three-dimensional reconstructions of 200 maxillary sinus septa were performed using Maxilim software. Ten measurements (length, lateral height, and thickness of the middle and medial region of the septum) were performed by 1 observer, 2 times, with an interval of 1 week between measurements. The angle between the septum and the maxillary plane was also measured. Finally, localization and orientation were assessed for each septum.ResultsThere was no statistically significant difference between the 2 intraobserver measurements (p>0.05).Student’s t-test was used to compare means. Middle height was the only measurement for which there was a difference between edentate and dentate patients (p=0.0095, edentate mean < dentate mean).The location of the septa observed in our study groups demonstrated greater prevalence in the posterior region than in the anterior and middle regions. For the spatial orientation of the septum, we found that most septa (81.2% in dentate patients, 53% in edentate patients) were oblique.ConclusionsThree-dimensional evaluation of maxillary sinus septa using 3D CBCT imaging showed that the sinus septum could offer an alternative site for implant placement in the maxillary sinus.

“…However, like any surgical intervention, this procedure is also associated with several complications, which may compromise the outcome of the surgery and the success of the implant treatment . A thorough knowledge of the anatomy and possible variations of the maxillary sinus is therefore essential in order to minimize the risk of potential complications related to the procedure . Cone beam computed tomography (CBCT) may be a useful diagnostic tool for providing a comprehensive radiographic assessment before SFE surgery…”

Background Complications arising from sinus floor elevation (SFE) with lateral approach surgery can be avoided by means of maxillary sinus examination in the preoperative period. Purpose To investigate anatomical variations in the maxillary sinus by making use of cone beam computed tomography (CBCT) in terms of SFE with a lateral approach. Materials and Methods Two hundred twenty eight maxillary sinuses in 114 patients were included. Parameters such as the position and diameter of the posterior superior alveolar artery (PSAA) canal, the frequency and localization of the septa or accessory maxillary ostium (AMO), and lateral wall thickness values were subjected to statistical analysis. Results Septa were observed in 35.1% of sinuses. The majority of septa were determined in the middle region (48.8%). Additionally, 71.1% of PSAA canals were intraosseous, generally exceeding 1 mm in diameter (68.9%). The shortest mean perpendicular distance between the sinus floor and the PSAA canal was determined in the first molar region (9.22 ± 5.66 mm). Similarly, the highest mean sinus lateral wall thickness was determined in the first molar region, in the area 3 mm distant from the sinus floor (2.42 mm ± 0.88 mm). AMO was detected in 40.8% of sinuses. Conclusion CBCT‐guided treatment planning may be beneficial prior to SFE procedures in order to avoid surgical complications.

“…In a study by Kim et al, 20 septa were found in 50.8 and 23.7% of the sinuses in the middle and posterior segments respectively. In studies by Pommer et al 27 and Bornstein et al, 28 the most frequent positions of the septa were above the 1st and 2nd maxillary molars. In a study by Shahidi et al, 29 septa were present in the anterior, middle, and posterior segments of the sinuses in 58.9, 21.1, and 20% of the cases respectively.…”

Introduction: The present study was undertaken to evaluate the anatomy of the maxillary sinus in relation to its position and the height of its septa, using cone beam computed tomography (CBCT). Materials and methods:In this descriptive retrospective study, 300 CBCT images of maxillary sinuses of patients with posterior maxillary edentulism were evaluated. The maxillary sinus septa were evaluated in relation to their prevalence, height, and position; t-test and Mann-Whitney tests were used for the analysis of data.Results: Sinus septa were detected in 44% of the subjects, with equal frequencies in the anterior, middle, and posterior positions. The mean height of the septa was 3.6 ± 1.56 mm. Conclusion:In a population of Iranian subjects, in half of the cases, the sinus septa might be present in the anterior, middle, and posterior positions.Clinical significance: In order to avoid intraoperative problems during sinus lift procedures, it is necessary to accurately evaluate the sinus, preferably with the use of CBCT.
