Linear and Volumetric Analysis of Maxillary Sinus Pneumatization in a Sri Lankan Population Using Cone Beam Computer Tomography

Abstract

Objective. The objectives of this study were to evaluate the linear and volumetric measurements of the maxillary sinus in relation to sex and side on cone beam computer tomographic (CBCT) images in a Sri Lankan population. Methods. A total of 20 sets of CBCT images selected from the database at the Division of Oral Medicine and Radiology, Faculty of Dental Sciences, University of Peradeniya, Sri Lanka, were evaluated. Linear measurements were obtained in a craniocaudal (height), anteroposterior (length), and mediolateral (width) dimensions. Volume was computed by using the same data using a computerized 3D modeling software developed for 3D measurements and calculations. Results. The maximum mean craniocaudal dimension was at the level of the 1st and the 2nd molar tooth bilaterally. The largest average craniocaudal, mediolateral, and anteroposterior extensions of the maxillary sinus using CBCT were 31.71 ± 5.44 mm , 21.28 ± 5.09 mm , and 32.92 ± 4.31 mm , respectively. The differences between the sides and sex showed no statistical significance ( P > 0.05 ), except for the maximum average value in craniocaudal dimension which showed a statistically significant difference in relation to gender ( P = 0.02 ). Conclusion. There is no significant difference in the largest average craniocaudal, mediolateral, and anteroposterior extensions of the maxillary sinus when gender and side were compared. However, the maximum average value in craniocaudal dimension had a statistically significant difference in relation to gender. This study provides valuable knowledge of the anatomical dimensions of the maxillary sinus which may help clinicians in treatment planning.

Effects of polymethyl methacrylate-based bone cement graft for treating excessive gingival display and its dimensional facial changes: 12-Month clinical study

“…The measurement of anatomical structures within tomographic imaging, such as teeth, bone, and the maxillary sinus, constitutes a well-established practice in the field of dentistry. 36 , 37 , 38 , 39 , 40 Nonetheless, it is worth noting the lack of published literature pertaining to the three-dimensional volumetric measurement of PMMA grafts after their implantation. Three-dimensional technology has been used for the fabrication and subsequent printing of PMMA grafts for the management of gingival smile.…”

Assessment of Factors Effecting Healthy Maxillary Sinus Volumes With CBCT

“…However, in some studies, there was no significant difference between gender and maxillary sinus volume. 9,[16][17][18] The different results may be due to the differences in female-male ratio, race, and in sinus volume calculation methods. In this study, the mean maxillary sinus volume was 61.46 ± 20.73 cm³ in men and 49.96 ± 19.66 cm³ in women, and the difference between them was statistically significant.…”

Cases of Skull Bones Hyperpneumatization

“…В литературе описано более 50 вариантов строения воздухоносных костей черепа, включая их гиперпневматизацию (Earwaker, 1993;Marino et al, 2020). Диагностирование гиперпневматизации сопряжено с определенными сложностями, так как у взрослого населения без видимой/верифицированной патологии линейные размеры и объемы лобной, верхнечелюстной и клиновидной пазух варьируют в широком диапазоне (Hettiarachchi et al, 2021;Metin-Gürsoy et al, 2020;Jaworek-Troć et al, 2021). Поэтому, кроме оценки размеров воздухоносной полости, следует учитывать и другие критерии.…”

“…More than 50 variants of the structure of the pneumatized skull bones, including their hyperpneumatization, have been described in the literature (Earwaker, 1993;Marino et al, 2020). Diagnosing hyperpneumatization is associated with certain diffi culties, because in the adult population without visible/verifi ed pathology, the linear dimensions and volume of the frontal, maxillary and sphenoid sinuses vary considerably (Hettiarachchi et al, 2021;Metin-Gürsoy et al, 2020;Jaworek-Troć et al, 2021). Therefore, in addition to assessing the size of the air space, other criteria should be considered.…”
