Abstract

Objectives: The aim of
this study is to perform morphometric analysis of the foramen magnum (FM) and
clivus using cone-beam computed tomography (CBCT) and to evaluate their
applicability in age and gender estimation.

Materials and Methods: CBCT
images of 412 individuals (248 females and 164 males) were included in the
study. The sagittal dimension (SD) and transverse dimension (TD) and area of
the FM were measured. The width and length of clivus were calculated.  The data were statistically analyzed with
ANOVA, Kruskal-Wallis and t-tests to assess the level of significance for sex
and age.

Result: The mean values
of SD, TD, area of FM and width and length of clivus were higher in males than
in females. Statistically significant differences were found between sexes for
all variables (p< 0.05). There was no statistically difference between age
and FM dimensions (p > 0.05). There was a significant relationship and
positive correlation between length of clivus and age groups (p=0.009,
r=0.351).

Concusion: CBCT provides
valuable information about the dimensions of the FM and clivus, and can be used
reliably for anthropometric analysis and forensic medicine in the field of sexual
dimorphism. The length of clivus can also help in determining age groups.

Keywords:Age estimation,
CBCT, clivus, foramen magnum, sex estimation .

  

Yaş ve Cinsiyet Tayininde Foramen
Magnum ve Klivusun Konik Işınlı BT Kullanımı ile Değerlendirilmesi

ÖZ

Amaç: Bu çalışmanın
amacı foramen magnum (FM) ve klivusun morfometrik özelliklerini konik ışınlı bilgisayarlı
tomografi (KIBT) ile belirleyip ve yaş ve cinsiyet belirlemede
kullanılabilirliğini değerlendirmektir.

Materyal
ve Metod:
412 bireye (248 bayan ve 164 erkek) ait KIBT görüntüsü çalışmaya dahil edildi.
FM’ un   sagittal boyutu (SB),
transversal boyutu (TB) ve alanı ölçüldü. klivusun genişlik ve uzunluğu
ölçüldü. Veriler, cinsiyet ve yaş için önem düzeyini değerlendirmek amacıyla
ANOVA, Kruskal-Wallis ve t-testleri ile istatistiksel olarak analiz edildi.

Bulgular: SB,
TB, FM alanı ile klivus genişliği ve uzunluğuna ait ortalama değerler
erkeklerde kadınlara nazaran yüksek bulundu. Tüm değişkenler için cinsiyetler
arasında istatistiksel olarak anlamlı fark görüldü. klivusun uzunluğu ile yaş
grupları arasında anlamlı bir ilişki ve pozitif korelasyon görüldü (p=0.009,
r=0.351).

Sonuç:
KIBT, FM ve klivus boyutları hakkında değerli bilgiler sağlar ve cinsiyet
ayrımında antropometrik ve adli tıp alanında güvenilir bir şekilde
kullanılabilir. Ayrıca klivusun uzunluğu da yaş gruplarının belirlenmesinde
yardımcı olabilir.
