A PRELIMINARY STUDY ON INCIDENCE OF CRANIAL SUTURAL BONES BY 3D VOLUME RENDERING OF CT SCAN IN CURRENT POPULATION IN EASTERN INDIA
International Journal of Anatomy and Research
Sutural bones are supranumary bones occurring along the sutures and completely surrounded by sutures of the skull. Their number, morphology and location vary in skulls. The knowledge of these bones is imperative in surgery, medicolegal cases involving child abuse or fracture of skulls and for anthropologic identification of human populations. The studies on sutural bones have traditionally been based on the studies of dry calvaria which are unreliable for the homogeneity of the population
... he population studied. Hence, this pilot study was undertaken to evaluate the feasibility of 3D volume rendering of CT scan data for study of sutural bones. Method: 3D volume rendering from 64-slice CT scan data from 64 patients was studied for incidence and location of occurrence of sutural bones. Results: Overall incidence of sutural bone occurrence was found to be 29.69%. The most common sites for sutural bones, in descending order of occurrence, were found to be parieto-occipital suture, asterion, and lambda. Conclusion: Sutural bone studies in concurrent populations such as this one are rare. The incidence of sutural bones in this study is similar to what another study on concurrent populations has reported. However, location of occurrence of sutural bones observed in this study was similar to all other sutural bone studies including those on dry skulls pointing to probable universality of this statistic. This preliminary study establishes the use of 3D volume rendering of CT scan data to be a valid means to acquire sutural bone data.
