Morphological analysis and morphometry of the foramen magnum: An anatomical investigation

Öz:

AIm: The objectives were to study the morphology of the foramen magnum in dry skulls and to evaluate its antero-posterior diameter,transverse diameter and the foramen magnum index.MaterIal and Methods: The foramen magna of 53 dry human cadaver skulls that were obtained from the neuroanatomy laboratory wereexamined. Different shapes of the foramen magnum were macroscopically noted and classified. The antero-posterior and transverse diameterswere measured and the average foraminal index was calculated.Results: The foramen magnum shapes were determined as a round shape in 22.6% of cases, egg shape in 18.9%, tetragonal in 18.9%, ovalin 15.1%, irregular in 15.1%, hexagonal in 5.6% and pentagonal in 3.8% of the cases. In 20.7% of skulls, the occipital condyle was observed toprotrude into the foramen. The mean antero-posterior and transverse diameter of the foramen magnum was determined as 31 ± 2.4 mm and25.2 ± 2.4 mm respectively. The average foramen magnum index was 1.2 ± 0.1.ConclusIon: The present study has determined the various shapes of foramen magnum and its morphometry. The data obtained may beof useful to the neurosurgeon in analyzing the morphological anatomy of craniovertebral junction. The findings are also enlightening for theanthropologists, morphologists and clinical anatomists

Foramen magnum morfolojik analizi ve morfometrisi: Anatomik bir inceleme

Öz:

AMAÇ: Foramen magnumun kuru kafataslarında morfolojisini incelemek ve anterioposterior çap, transvers çap ve foramen magnum indeksini değerlendirmek. YÖNTEM ve GEREÇLER: Nöroanatomi laboratuvarından elde edilen 53 kuru insan kadavra kafatasının foramen magnumları incelendi. Farklı foramen magnum şekilleri makroskopik olarak kaydedildi ve sınıflandırıldı. Antero-posterior ve transvers çaplar ölçüldü ve ortalama foramen indeksi hesaplandı. BULGULAR: Foramen magnum şekilleri vakaların %22,6’sında yuvarlak, %18,9’unda yumurta şekilli, %18,9’unda tetragonal, %15,1’inde oval, %15,1’inde düzensiz, %5,6’sında ekstragonal ve %3,8’inde pentagonaldi. Kafataslarının %20,7’sinde oksipital kondilin foramene doğru çıkıntı yaptığı gözlendi. Foramen magnumun ortalama anteroposterior ve transvers çapı sırasıyla 31±2,4 mm ve 25,2±2,4 mm olarak belirlendi. Ortalama foramen magnum indeksi 1,2±0,1 bulundu. SONUÇ: Mevcut çalışma foramen magnumun çeşitli şekilleri ve morfometrisini belirlemiştir. Elde edilen veriler nörocerraha kraniyovertebral bileşke morfolojik anatomisini analiz etmek açısından faydalı olabilir. Bulgular ayrıca antropologlar, morfologlar ve klinik anatomistler için faydalıdır.
