Abstract

Amaç: Kafa tabanı ile ilgili
olguların tanısında ve cerrahilerinde doğru bir yaklaşım için bölgenin normal
anatomisini ve morfometrik ölçümlerini bilmek klinisyenler için oldukça büyük
bir önem taşımaktadır. Bu çalışmanın amacı Türk popülasyonunda Foramen Magnum
(FM) ile Clivus’un ve ilgili yapıların morfometrik ölçümlerini değerlendirmek
hedeflenmiştir.

Materyal ve Metot:
Retrospektif olarak 313 hastanın baş ve boyun bölgelerinin bilgisayarlı
tomografi anjiyografi (BTA) görüntüleri incelendi. Clivus uzunluğu (LoC),
clivus ve FM’un arka kenarı arasındaki açı (C-FM), clivus’un arka yüzeyi ile,
dens axis’in arka kenarı arasındaki açı (C-D), FM’un antero-posterior çapı
(FMap), FM’un lateral kenarları arasındaki en geniş transvers mesafe (FMt) ve
FM alanı (FMa) ölçüldü.

Bulgular: Sırasıyla LoC, C-FM, C-D,
FMap, FMt ve FMa’nın ortalama değerleri kadın hastalarda 32,1
± 3,4 mm, 153,46° ±
9,13, 140,61° ± 11,93, 34,72 ±
2,57 mm, 29,25 ± 2,1 mm ve 733,26 ± 102,09 mm² iken erkek hastalarda
35,2 ± 4 mm, 149,93° ±
8,6, 141,28° ± 10,33, 36,29 ±
2,89 mm, 30,79 ± 2,27 mm ve 800,12 ± 110,62 mm² olarak ölçüldü.

Sonuç: Kafa tabanı ile ilgili yapılara ait ölçümler BTA ile kolay bir şekilde
değerlendirilebilir. Bu ölçümler klinisyenler için tanı ve tedavi için büyük
önem taşımaktadır ancak toplumlar arası farklılıklar göz önünde
bulundurulmalıdır

Relations Between Foramen Magnum and Associated Structures Located Within the Skull Base of The Turkish Population

Abstract

Aim:
For reliable diagnosis and surgical
approach, a fundamental knowledge of the normal anatomy and the morphometric
measurements of the skull base are important to the clinicians. The aim of this study is
to evaluate the morphometric dimensions of Foramen Magnum (FM) and clivus with
respect to the related structures of Turkish population.

Methods:
313
patients’ computed tomography angiography (CTA) image series of head and neck
region was examined retrospectively. Length of the clivus (LoC), angle between
the clivus and posterior margin of FM (C-FM), angle between the line along the
posterior surface of the clivus and the other line along the posterior side of
the dens of axis (C-D), antero-posterior diameter of the FM (FMap), largest
transvers distance between lateral margins of the FM (FMt) and the area of the
FM (FMa) were measured.

Results:
The mean values of LoC, C-FM, C-D, FMap, FMt and FMa in female
group are 32.1 ± 3.4 mm, 153.46° ± 9.13, 140.61° ± 11.93, 34.72 ± 2.57 mm, 29.25 ± 2.1 mm and 733.26 ± 102.09 mm²
respectively. And also the mean values of LoC, C-FM, C-D, FMap, FMt and
FMa in male group are 35.2 ± 4 mm, 149.93° ± 8.6,
141.28° ± 10.33, 36.29 ± 2.89
mm, 30.79 ± 2.27 mm and 800.12 ± 110.62 mm² respectively.

Conclusion:
Parameters
of the structures related to the skull base, especially the FM can easily be
evaluated using CTA.
