“…Bruno et al confirmed that 40% of patients have bony septa that can partially separate the maxillary sinus [37]. In our study, 98% of the dentate patients and 96% of the edentate patients presented with complete septa.…”

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.

The implant-supported prosthetic rehabilitation of the posterior maxilla may require sinus-grafting procedures due to poor quality and low volume of bone. This can be accomplished using a "lateral window" sinus augmentation or with an osteotome sinus floor elevation (OSFE). The hydrodynamic ultrasonic cavitational sinus lift (HUCSL) (Intralift) is derived from the osteotome technique and allows the reduction of some of the traumatic effects of the osteotome technique. The aim of this study was to compare OSFE and the HUCSL procedures on fresh human cadaver heads. Primary outcomes were the height and width of the grafting area in the sinus floor area. Eighty-four maxillary sinuses were selected. On each fresh cadaver head, 2 sinus lifts were done using OSFE and HUCSL in the maxillary sinuses. Computerized tomography scans were performed on each head before and after the surgeries. Measurements were done on radiologic pictures using dedicated software, and the integrity of the sinus membrane was observed after dissecting the maxillae. The use of HUCSL resulted in a significantly higher sinus floor augmentation in the mesio-distal and bucco-palatal direction compared with the osteotome technique (P < .001). There was no correlation between mesio-distal and bucco-palatal diameters of sinus floor augmentation when only the osteotome protocol was considered (r = 0.27 and P = .08). In contrast, the mesio-distal and bucco-palatal diameters of floor augmentation were correlated when the HUCSL protocol was considered (r = 0.79, P < .001). HUCSL represents a good alternative method for sinus floor elevation.

“…One of the most common morphological variations was described by Underwood as sinus septa (Underwood, 1909). Septa prevalence should be considered on each occasion prior to sinus lift surgery, as its presence may lead to perforation or tearing of the Schneiderian membrane or a reduction in the capability of augmentation steps and may force the surgeon to enlarge the operation to an extent that it may result in a decrease in treatment success rate (Underwood, 1909;van den Bergh et al, 2000;Chanavaz, 1990;ten Bruggenkate et al, 1998;Ulm et al, 1995;Ella et al, 2008).…”

SUMMARY:The aim of this study was to examine the prevalence, location and morphology of maxillary sinus septa, and in particular sagittally orientated forms, which cannot be visualized by classic 2D x-rays. Thereby authors would like to provide information about the potential patient group, to be referred for the computed tomography scan before sinus lift procedure. The analysis was based on 216 computed tomography archival images. The exclusion criterion was occurrence of any suspected pathology in the maxillary region. The septa prevalence that was investigated in computed tomography was high (49%) with the mean height of 5.44 mm. The incidence of sagittally orientated septa as a challenge in 2D x-rays was 10%, with the second molar region as the most frequent location. Based on the obtained results and radiation safety principles, the authors suggest that orthopantomogram x-ray may be a sufficient ancillary radiological examination before beginning preimplant surgical procedure in the area of the maxillary sinus.
