Easy and Unbiased Determination of the Maxillary Sinus Volume

Abstract

SUMMARY:Determining the volume of the maxillary sinus is necessary in certain procedures. We present a simple method for estimating the volume of the maxillary sinus from groups 3, 5 and 9 coronal CT scan using the Cavalieri method combined with systematic sampling and evaluated randomized images. We used 10 dry skulls submitted to the TC. The actual volume was determined using silicone adapted to the maxillary sinus cavity. The estimated volume showed a high correlation with real volume, with no differences between groups. We concluded that it is possible to estimate without bias and with high accuracy the volume of the maxillary sinus from a minimum of 3 CT images obtained through randomized systematic sampling and the proposed method.

Validity of maxillary sinus volumetric measurements using the 3D orthogonal cone beam computed tomography images versus direct skull volumetric measurements: An in vitro study

“…The reference standard in this study was the indirect volume measurements of the maxillary sinus rubber impression using fluid displacement technique of the recorded rubber impression following Arquimedes principle (8) .…”

Computed tomography-based volumetric tool for standardized measurement of the maxillary sinus

“…For example, volumetric evaluation contributes to the assessment of patients with chronic rhinosinusitis (CRS) because such a volumetric method better correlates with the severity of CRS compared with most widely used Lund-Mackay CT scoring system [ 10 ]. Furthermore, MS volume have been evaluated for verifying the response to chemo- and radiotherapy in malignant tumors [ 11 ] and for planning procedures that involve sinus floor elevation in the placement of implants [ 12 , 13 ] and endoscopic sinus surgery [ 2 , 14 ].…”

Morphological, Stereological and Histometrical Assessment of the Testicular Parameters between Holstein and Simmental Bulls

“…Recently, there are some measurement techniques, including caliper (Gouletsou et al, 2008), orchidometry (Paltiel et al), ultrasonography (Gouletsou et al; Paltiel et al) and the combination of MR-I and stereological volume estimation tool "Cavalieri method" (Coronado et al, 2011;Kabay et al, 2009;Gocmen-Mas et al, 2010) for in vivo testis volume measurements, and furthermore water displacement method "Archimedean principle" and individual administration of Cavalieri method (Akosman & Özdemir, 2010;I˙nce et al, 2012;Dorostghoal et al, 2011) for in vitro testis volume measurements. The volume estimation method "Cavalieri method" (Gundersen et al, 1988(Gundersen et al, , 1999) is unbiased and current way to estimate the volume and volume fractions of the organ (Gundersen et al, 1988).…”
