About the Study
Craniometry being the scientific study and measurement of the
skull has been useful in anthropometry for the morphometric and
non-morphometric identification of the sex and age and in forensic
practice when cranial remains are compared with living photographs.
Cranial dimensions and cranial indices are considered as simplest
and most efficient way to indicate facial differences and age
variations. For instance, cranial volume expresses several aspects of
growth and development and permits critical evaluation of unusually
large or small crania. Through skull morphology, population
differentiation has been explored by recent studies, showing that not
only vault features but also various facial characteristics are
responsible for both inter and intra-regional differences within a
region. These cranial index variations between and within population
have been attributed to a complex interaction between genetic and
environmental factors. There are several skeletal indicators that are
used to estimate age at death for adults such as Cranial suture
closure or suture synostosis of which Nawrocki introduced 14
regression equations for determining age at death using these
sutures and as Acsadi and Nemeskeri opined in an attempt to create
an age estimation method using endocranial suture closure while
examining 285 symmetrically closing crania suggest that as age
increases so does mean suture closure [1-3].
The aim of the study is to investigate the craniometric patterns in
the Nigerian population based on three dimensional computed
tomographic data with the objectives of determining the age of
individuals in the eastern part of Nigeria as well as determining if the
skull of individual varies with age using computed tomography since it
enables 3-D reconstruction and assesses the cranium data both inner
and outer anatomical landmark for the craniometric study.
Methodology involve a descriptive study design with age was
determined using standard ageing techniques, as specified in
Scheuer and Black and Cox. Normally, the practice consists of taking
precise measurements using ‘anatomical landmarks’ on the skull.
The inclusion criteria include individuals within ages 25 to 60 with no
incidence of head trauma or abnormality, no loss of teeth from the
maxilla and no chronic illness that might affect the cranium [4].
The exclusive criteria include individuals with anatomical
deformities and children. The data was collected from a CT SCAN’s
radiological department in Abia state Diagnostic center, Umuahia and
Union diagnostic center, Port Harcourt Rivers State. Patients were
scanned in the radiology department and the CT data were
processed in a computer workstation at the department. A spiral
computed tomography scanner (SIEMEN) was used to obtain data
from 150 crania. The CT scan acquisition was performed with 1.5mm
slice thickness and reconstruction was done with 1.0m ,2m slice
thickness [5,6].
