Analysis of the Prevalence, Location, and Morphology of Maxillary Sinus Septa in a Northern Chinese Population by Cone Beam Computed Tomography

Abstract

Purpose. The purpose of this study is to survey the prevalence and morphology of the maxillary sinus septum, which might increase the rate of maxillary sinus membrane perforation during maxillary sinus floor elevation surgery, among northern Chinese, and to further analyze the relationship between gender, age, edentulous type, and prevalence of maxillary sinus septa. Methods. The cross-sectional retrospective study was based on an analysis of Cone Beam Computed Tomography (CBCT) images of maxillary sinus which had been obtained from patients who visited radiology department of Beijing Stomatology Hospital of Capital Medical University (Beijing, China) during the period from January 2019 to December 2019. The data of demographic characteristic, prevalence, position, direction, and morphology of maxillary sinus septum were collected and further analyzed by SPSS version 25.0.1 and R version 3.5.1 software program. Results. 595 patients were included in this study, and 1190 maxillary sinuses were analyzed and the incidence rate of the sinus septum was 46.9%. 399 (33.5%) sinuses had one or more septa in 279 (46.9%) patients. In addition, maxillary sinus septa incidence showed no significant differences among gender, age, and edentulous type. The segment second molar had the highest incidence rate of septa. Conclusion. In this study, a higher incidence of the maxillary sinus septum was found in the northern Chinese, and its distribution varied with its position, morphology, and direction.

Cone-Beam Computed Tomographic Analysis of Maxillary Sinus Septa among Yemeni Population A Cross-sectional study

“…This nding is consistent with Shen et al [22] who observed no correlation between septa prevalence and the absence of maxillary rst or second molars, consistent with recent studies [2,18,21,[42][43][44]. The present study contradicts other studies [38, 45,46] The thickness of the membrane at the septa origin is almost twice as thick as it is from the septa origin [53].…”

“…In the literature, the prevalence of maxillary sinus septa varies signi cantly between studies of various nations and ethnicities. China, Korea, Brazil, Iran, Saudi Arabia, Turkey, and South Africa reported rates of 46.9%, 22.93%, 27%, 44,4%, 44.8%, 45.9%, 47.6%, and 69%, respectively [21][22][23][24][25][26][27][28]. The sample size, criteria of septa (2-4 mm height), races and nations, and imaging modalities (CBCT, CT, panoramic, surgical observation, cadavers) could in uence the different septa prevalence rates [29].…”

“…This disparity could be attributed to differences in the populations being studied. Wang et al (26) assessed sinus septa in CBCT images. They found that the prevalence of septa was 50.2% in patients with full dentition, 44.2% in those with partial dentition, and 41.7% in edentulous patients.…”

Prevalence of Incidental Findings in Maxillary Sinus Using Cone Beam Computed Tomography – A Retrospective

“…Despite of its poor soft tissue contrast, CBCT images can aid in viewing inflammatory pathologies and sinus opacification [4]. The prevalence of maxillary sinus pathologies in asymptomatic patients ranged widely between 10.9 % and 69.1 % across studies in literature [5][6][7][8][9]. Maxillary sinus abnormalities can be classified as developmental, inflammatory, cystic, calcifications or neoplasms [10].…”
