Asterion yerleşiminin posterolateral intrakraniyal girişimler açısından morfometrik değerlendirilmesi
Abstract
Amaç: Beyin cerrahisinde, fossa cranii
posterior’a ulaşmayı gerektiren cerrahi girişimlerde, cranium’a giriş noktası yüzeyel anatomik belirgin noktaların
yardımıyla belirlenir. Asterion’un, cranium’un posteroateralinde kemik
yüzeyindeki belirgin noktalar ve sulcus
sinus transversi (SST), sulcus sinus
sigmoidei (SSS) veya bunlara ait bileşke ile olan ilişkisinin morfometrik
olarak incelenmesi amaçlandı.
Gereç ve Yöntem:
Çalışmada, Dokuz Eylül Üniversitesi Tıp Fakültesi
Anatomi Anabilim Dalı Laboratuvarı kemik koleksiyonunda mevcut, yaşı ve
cinsiyeti bilinmeyen 172 adet erişkine ait bütün kuru kemik cranium’lar ile 10 adet calvaria’sı kaldırılmış kuru kemik cranium’lar değerlendirildi. Ölçümler
0.01 mm’ye duyarlı dijital kumpas ve 1 mm’ye duyarlı mezura kullanılarak
yapıldı.
Bulgular: Asterion-inion 61,61±4,08 mm, asterion-processus
mastoideus 47,81±5,09 mm, asterion-Henle
çıkıntısı 41,63±3,95 mm, asterion-opisthion
61,71±3,69 mm, asterion-processus
zygomaticus’un kökü sağda 55,11±3,86 mm, solda 54,37±4,35 mm olarak
ölçüldü. Calvaria’sı kaldırılmış kuru
kemik cranium’larda asterion’un dört cranium’da bilateral, bir cranium’da
unilateral sol tarafta SST içinde olduğu, diğerlerinde SSS-SST bileşkesi içinde
lokalize olduğu gözlendi.
Sonuç: Asterion, SST, SSS veya bunlara ait bileşkenin içinde yer aldığı ve asterion’un izdüşümü hizasında sinus
yapılara ait oluk genişliğinin 10,25±2,18 mm olduğu saptandı. Asterion’dan yaklaşık 10 mm üstü ve
altının girişim açısından sinus
transversus veya sinus sigmoideus
yaralanma riski taşıyacağı için, fossa
cranii posterior’a yapılacak cerrahi girişimlerde, yüzeyel belirgin
noktaların yardımıyla asterion’un
yerinin belirlenmesi, venöz sinüslerin korunmasını sağlayabilir.

Abstract
Aim: In neurosurgery, surgical approaches that require
access to fossa crani posterior is done with the help of superficial anatomic
landmarks to determine the entrance point. It was aimed to morphometrically examine
asterion and its relation with superficial landmarks in the postero-lateral
aspect of cranium, groove for transverse sinus (GTS), groove for sigmoid sinus
(GSS) and GTS-GSS junction.
Materials and Methods: In this study, 172 dry adult
human crania and 10 crania with removed calvaria studied which are belong to
Anatomy Laboratory, School of Medicine, Dokuz Eylul University. Measurements
were performed by using a digital caliper sensitive to 0.01 mm and tape measure
sensitive 1 mm.
Results: Measured parameters were as asterion-inion
61.61±4.08 mm, asterion-mastoid process 47.81±5.09 mm, asterion-Henle spine
41.63±3.95 mm, asterion-opisthion 61.71±3.69 mm, asterion-posterior root of
zygomatic process 55.11±3.86 mm on the right side and 54.37±4.35 mm on the left
side. In crania with removed calvaria, asterion was found to be located
bilaterally in GTS in four crania, unilaterally on left side in one cranium and
in others in GTS-GSS complex.
Conclusion: Asterion takes place within
the GSS, GTS or its junction. At the projection point of asterion width of the
groove related to venous sinuses was determined as 10.25±2.18 mm. Determination
of location of asterion with the help of superficial landmarks may provide
protection of venous sinuses during surgical procedures performed in posterior
cranial fossa, since transverse or sigmoid sinus will be at risk of injury 10
mm above or below from the asterion.
