“…Other more recent papers have published reports using the Cavalieri principle on imaging studies. This formula uses two-dimensional images from imaging studies in order to get a three-dimensional volume 10,11 . Aside from the techniques using imaging series, other studies have been made using cadavers or dry skulls 12,13 .…”

Morphological variability of paranasal sinuses is well known for endoscopic surgeons and anatomists alike. The ethmoid sinus is the most complex and variable of all paranasal sinuses, due to the fact that its development is not yet well known and is influenced by many factors. Volumetric studies of the sinuses have been made using dried skulls, cadaver heads and imaging studies, but there are still not sufficient data in order to name a standard value for each sinus. Few data can be found especially regarding the ethmoid sinus. In this paper, we measured the volumes of ethmoid lateral masses, and for anterior and posterior groups of cells, using imaging studies and a volumetric feature of our imaging studies. Results showed an average volume between 7.34 cm3 and 8.39 cm3for the ethmoid lateral mass, between 4.33 cm3and 4.92 cm3 for the anterior ethmoid and between 3.01 cm3and 3.47 cm3for the posterior ethmoid groups. We also found that the average volume of the anterior ethmoid occupies between 58-59% of the whole volume, while the posterior ethmoid occupies only 41-42% of this volume.

“…Midclavicular (MCL), craniocaudad (CC), or midhepatic (MHP) CC measurements have been used in ultrasound (US) to estimate liver size [4,5]. These methods have been extrapolated to advanced imaging modalities, including computed tomography (CT) and MRI [6][7][8][9]. There are no studies correlating simple linear hepatic measurements on MRI and hepatic volume.…”

“…In studies analyzing the effect of section thickness on volume estimations of organs or cavities by using CT images, authors reported underestimations of the volumes which were caused by increases in slice thickness [18,19]. In our study, 1.4-and 2.2-mm-thick slices caused statistically significant underestimation problem.…”

“…After the polymerization, silicon impressions were immersed into a pycnometer filled with water, and the volumes were calculated using the density and weight of the water run-over, based on Archimedean principle. Measurements by the water displacement method were accepted as the actual volume values and served as gold standard [18][19][20][21].…”

The purpose of this study was to investigate the possible effects of section thickness on volume estimations obtained by cone beam computed tomography. Intraosseal cavities representing bone defects on vestibular sides of the two dry sheep mandibles were scanned by a cone beam computed tomography system. Consecutive sections at 0.2, 0.6, 1, 1.4, and 2.2 mm thickness were used to estimate the volumes of the cavities using the Cavalieri principle of stereological methods. Estimated volumes are then compared with the volumes obtained by the Archimedean principle. In 0.2-, 0.6-, and 1-mm-thick slices, the volumes estimated by the Cavalieri principle did not differ from the volumes by the Archimedean principle (p > 0.05). The 0.2 mm slice-thickness group had the highest asymptotic significance value (p 00.6). Although the thinnest slice appears to provide the most accurate values, slice thickness up to 1 mm can be chosen for volume calculations on CBCT images.
