Computed tomographic measurement of maxillary sinus volume and dimension in correlation to the age and gender (comparative study among individuals with dentate and edentulous maxilla)


Background : Although development and progress in various diagnostic methods, but still identification of remnantsof skeletal and decomposing parts of human is one of the most difficult skills in forensic medicine . Gender and ageestimation is also considering an important problem in the identification of unknown skull.The aims of study: To estimate volume and dimension of maxillary sinus in individuals with dentate and edentulousmaxillae using CT scan, and to correlate the maxillary sinus volume in relation to gender and age.Materials and Methods : This study included 120 patients ranged from (40-69 years), divided into two groups, dentategroup with fully dentate maxilla and edentulous group with complete edentulous maxilla, and each groupcomposed of 60 patients (30 males and 30 females) who admitted to spiral CT scan unit in X-ray Institute inBaghdad to have CT of the brain and paranasal sinuses from October 2011 to June 2012, who had complaints ofheadaches or with suspection of sinusitis but without pathological findings in maxillary sinuses. The maxillary sinusvolumes and dimensions (width, depth, and height) were measured with the help of the computer software in SpiralCT scan system.Results : The statistical analyses of maxillary sinus measurements for dentate and edentulous groups showed that thevolume and dimensions of maxillary sinuses in both groups were larger in males than females and they tend todecrease with the older age, in addition it is found that there was no significant differences in measurements ofmaxillary sinuses between dentate and edentulous groups, but the exception was in height measurements whichwere significantly higher in edentulous than dentate group for both genders.Conclusion: It's found that the volumes and dimensions of the maxillary sinuses were larger in males than in females,in addition to that they tend to be less with the older age, so the Computed Tomography measurements of maxillarysinuses may be useful to support gender and age determination in forensic medicine
