“…Sagittal intercondylar angle ranges between 55˚ and 84˚. Our findings correlate with those of Barut et al [35] 63,7±7,75˚ and Kizilkanat et al [34] as 62,2±9,1˚. A wide range reflects the asymmetry in the orientation, length and shape of OCs and may affect the lateral approach [3].…”

“…The shape, size, and angle of the OC is important for choosing the surgical procedure, and studies present varying findings for the measurements [12]. Although a 1/3-2/3 resection may not cause craniocervical instability, total resection may do so [35]. The same amount of partial condylectomy may cause greater occipitocervical instability in a short OC compared to a long OC.…”

“…In the present study, the average FM index was calculated as 1.2 ± 0.1. Testut and Latarjet (15) opined that wide, sagittally inclined and medially protruberant occipital condyles along with a FM index more In transcondylar approach, the anatomical landmarks of the FM should be well known in order to make a safe occipital condyle resection (1). The present study elucidates the morphometric data and the variations in the morphology of the FM with emphasis on their clinical implications.…”

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 were examined. Different shapes of the foramen magnum were macroscopically noted and classified. The antero-posterior and transverse diameters were 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%, oval in 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 to protrude into the foramen. The mean antero-posterior and transverse diameter of the foramen magnum was determined as 31 ± 2.4 mm and 25.2 ± 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 be of useful to the neurosurgeon in analyzing the morphological anatomy of craniovertebral junction. The findings are also enlightening for the anthropologists, morphologists and clinical anatomists. 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.ANAHTAR sÖZCÜKLeR: Foramen magnum, Morfoloji, Morfometri, Şekil, Kafatası

“…The topographic relationship between a lesion and neurovascular structures is the most important characteristic when selecting the appropriate surgical procedure, and the identification of anatomical variations is crucial in the prior planning of neurosurgery (George et al, 1988;Kratimenos & Crocard, 1993;Babu et al, 1994;Wen et al, 1997;Dowd et al, 1999;Rothon, 2000,;Nanda et al, 2002;Muthukumar et al, 2005;Barut et al, 2009).…”

Morphometric Analysis Related to the Transcondylar Approach in Dry Skulls and Computed Tomography

SUMMARY:The transcondylar approach (TA) has been used in surgeries to access lesions in areas close to the foramen magnum (FM) and is performed directly through the occipital condyle (OC) or through the atlanto-occipital joint and adjacent portions of the same. The objective of this study is to examine anatomical variations related to the TA by morphometric parameters of the FM, OC and of the hypoglossal canal (HC) in dry skulls and in computed tomography (CT). In 111 skulls, characteristics of the HC, and measures related to the FM, the HC and to the OC were examined. In CT, the measurements obtained bilaterally in 10 patients who underwent examination of the skull base in 1 mm-thick axial helical cuts were the distances from the outer half of the clivus to the opening of the HC; from the lower portion of the OC to the middle of HC; from the inner half of the clivus to the intracranial opening of the HC and to the midpoint of the HC; from the HC extracranial opening to the lower portion of the OC and to the outer half of the clivus. The results of CT measurements are consistent to previous studies of morphometric variations related to the TA, with no significant difference between the measurements obtained in the right and in the left sides, or related to gender. The data obtained by three-dimensional CT images are important in assessing the morphometric variations of pre-surgical patientsof TA.
