“…There was an increase in incidence reported when 3D radiographic techniques such as CT and CBCT were used to check for the existence of septa. [ 22 23 24 25 26 27 28 29 30 31 32 ] CBCT over a CT further provides for the advantages of lesser radiation dose and reconstruction of the image in different panoramic and axial sections.…”

Background: Augmentation of the maxillary sinus increases the lost height of ridge in the posterior maxilla. Bony convolutions from the floor of the sinus called septa may be encountered during the procedure and significantly impact the outcome of the procedure. Materials and Methods: For this retrospective study, 120 cone-beam computed tomography (CBCT) scans were collected from the archives of the department of oral radiology in the time period between January 2016 and August 2018. Planmeca Romexis ® software version 3.2.7 was used to check for the incidence, and then among the septa, plane of orientation, location with respect to the wall of the sinus, and in terms of relation to tooth were examined. The average height and average width of all the septa were measured using a measuring tool in the software. Results: Thirty-five of the total 88 patients showed septa in 40 sinuses, in which 36 sinuses showed one septum and 4 sinuses showed 2 septa. Forty-one septa were located on the floor of the sinus in the frontal orientation and 3 septa were located on the lateral wall of the sinus in the axial orientation. The mean height and mean width of the 41 septa on the floor of the sinus were 5.72 mm and 3.47 mm, respectively. The mean height of septa found on the lateral wall of the sinus was 5.59 mm. Conclusion: Septa had a higher tendency to be in bucco-palatal direction and on the floor of the sinus and frequent occurrence in the region of molars. A thorough prediagnostic evaluation using CBCT is necessary prior to sinus augmentation procedures.

“…Such a perforation can result in acute or chronic sinusitis and can lead to bone resorp-tion [1]. Mudgade et al [7] found the prevalence of septa to be 66.7% and Shahidi et al [16] found to be 45.4% with CBCT. Qian et al [12] compared the prevalence of septation among edentulous patients (57.4%) and dentate patients (39.7%) using CBCT imaging.…”

Background: The aim of this study was to evaluate the frequency of maxillary sinus pathologies and anatomic variations in elderly and edentulous patients by using cone-beam computed tomography (CBCT). Materials and methods: The study included elderly and young patient groups. The elderly group involved posterior edentulous and dentate patients. CBCT images were assessed, and the presence of any pathological findings, septa, accessory maxillary ostium, and Haller cell in each maxillary sinus were recorded according to the groups. Chi-square test was used to analyse the intergroup differences (p < 0.05). Results: There was no statistically difference between the young and elderly groups regarding the presence of a pathology (p = 0.077) and septa (p = 0.37), whereas accessory ostium (p = 0.009) was more common and Haller cell (p = 0.000) was less common in the elderly group when compared to the young group. There was no significant difference between the edentulous and dentate group regarding the presence of a pathology (p = 0.39), septation (p = 0.69) and Haller cell (p = 0.75); accessory ostium rate was found to be increased (p = 0,015) in edentulous patients. Conclusions: It was observed that the frequency of accessory maxillary ostium was increased in elderly, especially in edentulism. And the frequency of Haller cell was found to be decreased in elderly patients.

“…Cone Beam Computed Tomography (CBCT) is a comprehensive diagnostic tool that can reliably capture and provide a three-dimensional visualisation of the anatomy and pathology of the maxillofacial region since its introduction in the fi eld of dental care in the year 1998 [5]. The American Academy of Oral and Maxillofacial Radiology recommends the use of CBCT as an alternative to conventional CT for three dimensional imaging of maxillofacial structures [6,7].…”

“…In dentistry, evaluation of maxillary sinuses requires special attention especially during dental implant surgeries [8]. Due to the close proximity of the maxillary sinus to the posterior teeth, a threedimensional preoperative assessment of the maxillary sinus is also considered to be fundamental in planning pre-prosthetic surgeries [5,9].…”

Objectives: The knowledge of the normal morphology of the maxillary sinuses and their variations is important for maxillofacial radiologists to achieve a better evaluation and delineation of pathologies and for pre-implant evaluation of the maxilla. The aim of our study was to evaluate anatomical variations of maxillary sinuses using Cone Beam Computed Tomography (CBCT). Materials and methods: 150 CBCT images where bilateral maxillary sinuses were scanned were included in the study following the inclusion and exclusion criteria. 75 CBCT scans each of males and females were studied using the Planmeca Romexis software (Version 4.6.2). Multiplanar images were searched for the presence of anatomical variations such as septae, haller cells and ethmomaxillary sinus. The data were subjected to Chi square test using SPSS software to compare and relate gender and site based differences in the occurrence of the anatomical variations. Results: Sinus septa was the predominant variation in both males and females with significantly higher prevalence in females and on the right side. An ethmomaxillary sinus was seen significantly more often in males, while Haller cells did not show any gender based differences in their occurrence. Ethmomaxillary sinus and Haller cells showed no difference in occurrence on the right and left side. Conclusions: Anatomic variations of the maxillary sinuses are a common finding. It necessary for the clinicians to be familiar with these variations to avoid clinical complications especially in cases of implant placements.
