Multidetector CT Measurement of Maxillary Sinus Volume Using Dedicated Software to Determine Gender Difference in Normal Population

Background:Objectives:Methods: Identification of human remain requires a comparison between ante-mortem and post-mortem evidences, as such, the use of bones that are often easily recovered intact like the maxilla, becomes necessary although the skull and other bones may be badly disfigured. To determine the precision with which the maxillary sinus volumes identifies sex. 130 subjects (79 males and 51 females), between 20 - 80 years, with normal maxillary sinus CT anatomy, from head CT scans carried out at the Radiology Department of the Usmanu Danfodiyo University Teaching Hospital (UDUTH) Sokoto from 2008 to 2012 were involved in this study. The volume of each sinus was determined by the product of three linear measurements (craniocaudal (height), anteroposterior (dept) and transverse (width) diameters), using Neusoft Dual Slide Helical CT machine and the slice thickness. These measurements were performed on three-dimensional reconstructed images using V-works 3.0 program. The discriminant analysis showed that the accuracy with which the maxillary sinus volume could identify sex was 50.6% in males, and 60.8% in females. Computerized Tomography estimation of maxillary sinus volume may be of value to support sex determination in forensic anthropology.

Abstract Background The maxillary sinus has been considered as an important factor that affects the development of craniomaxillofacial bone. However, the correlation between the maxillary sinus and skeletal malocclusion is controversial. This study aimed to compare the dimensions of the maxillary sinus in patients with different vertical growth patterns and investigated the correlation between the maxillary sinus and craniofacial parameters.Methods This descriptive study included 90 patients from age 15 to 20 years old. According to the vertical growth patterns that were classified by MP-FH (angle between the mandibular plane and Frankfort horizontal plane), they were equally divided into three groups: high-, low- and normal-angle, and the gender ratio was 1:1. Cephalometric tracings were conducted from CBCT images, which were also used to measure the dimensions and volume of the maxillary sinus. Data were analyzed with one-way ANOVA, Pearson’s correlation coefficient, and multiple comparison LSD.Results The variables of the maxillary sinus, including the volume, length, and width, among different groups, were significant(p<0.05). The variables of mandibular body length were significantly correlated with the volume of the maxillary sinus (p<0.01), and the coefficient was 0.425.Conclusions The maxillary sinus volume, length, and width were larger in low-angle patients. The mandibular body length had a significantly positive correlation with the maxillary sinus volume.
