Abstract

Objective: The human falx cerebri is an important anatomical structure due to the hemispheres it is adjacent to and the dural venous sinuses it contains. It is also an important landmark in determining the midline in the interhemispheric transcallosal approach for lateral and third ventricular tumours in neurosurgical practises. Thus, the goal of this cadaveric study was to investigate the existence, number, and topography of fenestra on the falx cerebri in the Turkish population. Material and Methods: For this study, 60 adult Turkish cadaveric dura maters were examined. The number of falx cerebris and the existence and topography of fenestra on the falx cerebri was determined. The length and width of the fenestra were measured using a digital compass. Result: All falces cerebrum were single, and no double or triple falx cerebri were observed. There was fenestra on the falx cerebri in five cases (8.3% of all cases), and two of them included multiple foramina (%40 of all fenestrae). In addition, one fenestra was on the middle part of the falx cerebri, whereas the other was placed on the posterior part of this partition. The mean length and width of these fenestrae were 23.3x7.5 mm. Conclusion: The novel findings documented in this study may be important to increase the success rate of diagnostic and operative procedures of the falx cerebri or adjacent structures and to minimise intraoperative complications during neurosurgical applications.

Özet

Amaç: İnsan falx cerebri’si, komşu olduğu hemisferler ve içerdiği dural venöz sinüsler nedeniyle önemli bir anatomik yapıdır. Ayrıca, nöroşirürji uygulamalarında lateral ve üçüncü ventrikül tümörleri için interhemisferik transkallozal yaklaşımda orta hattın belirlenmesinde önemli bir landmarktır. Bu nedenle, mevcut kadavra çalışmasının amacı, Türk toplumunda falx cerebri üzerindeki fenestra varlığını, sayısını ve topografyasını araştırmaktı. Gereç ve Yöntem: Bu çalışma için 60 yetişkin Türk kadavra dura mater’i incelendi. Falx cerebri sayısı, falx cerebri üzerinde fenestra varlığı ve fenestranın topografyası belirlendi. Fenestranın uzunluğu ve genişliği dijital kaliper kullanılarak ölçüldü. Bulgular: Falces cerebrorum'un tamamı tekli olup, ikili veya üçlü falx cerebri gözlemlenmedi. Beş olguda (tüm olguların %8,3'ü) falx cerebri üzerinde fenestra vardı ve bunların ikisinde çoklu foramenler (tüm fenestraların %40'ı) vardı. Ayrıca fenestralardan biri falx cerebri'nin orta kısmında, diğeri ise bu bölümün arka kısmında yer alıyordu. Bu fenestraların ortalama uzunluğu ve genişliği 23,3x7,5 mm idi. Sonuç: Bu çalışmada belgelenen yeni bulgular, falx cerebri veya komşu yapılara yönelik tanısal ve operatif prosedürlerin başarısını artırmak ve nöroşirürji uygulamaları sırasında intraoperatif komplikasyonları en aza indirmek için önemli olabilir.
