Abstract

Amaç:
Bu
radioanatomik çalışmada, optik sinir cerrahisi açısından önemli bir referans
noktası olması nedeni ile optik strut’ın morfometrik özellikleri ile ilgili
veri elde edilmesi amaçlanmıştır.

 

Materyal-Metot: Tıp
Fakültesi Anatomi Anabilim Dalı envanterinde bulunan 7 adet erişkin insan kuru
kafatası bu çalışmaya dahil edildi. Direkt anatomik ölçümler dijital kumpas ve
radyolojik ölçümler bilgisayarlı tomografi yardımı ile elde edildi.
Prekiyazmatik sulkusa göre optik strut’ın konumu değerlendirildi. 

 

Bulgular: Direkt anatomik ölçümlerde optik strut’ın uzunluğu
ve genişliği
4.53±0.74 mm ve 4.83±1.34 mm olarak bulundu.
Bilgisayarlı tomografide ise optik strut’ın uzunluk ve genişliği 4.13±1.27 mm
ve 4.31±0.82 mm olarak tespit edildi. Direkt anatomik ölçüm ve bilgisayarlı
tomografide iki strut arası mesafe 16.83±2.56 mm ve 15.91±1.81 mm olarak
bulundu. Bilgisayarlı tomografi ve direkt anatomik değerlendirmede optik
strut’ın 4 kuru kafada sulkal, 2 kuru kafada postsulkal ve 1 kuru kafada
asimetrik olduğu belirlendi.











Sonuç: Optik strut’ın cerrahlar açısından bir referans noktası olması ve
anteriyor klinoid proses rezeksiyonu sırasında hasarlanabileceği dikkate
alındığında, sayısal verilerimiz optik sinir çevresinde yapılan cerrahi
müdahaleler sırasında faydalı olabilir.
