Presigmoid approaches are used for lateral access to the upper and middle third of the clivus and the petrous apex. These approaches provide anterolateral visualization of the brain stem after mobilization of the transvers-sigmoid sinus junction. In comparison to classical subtemporal or paramedian suboccipital approaches, these skull base approaches provide safer and wider surgical access to petroclival region lesions and enable more complete resections. In dealing with tumors in the petroclival region the main goal is maximal safe resection. The complications due to presigmoid approaches are generally temporary and manageable.

Öz

Presigmoid girişimler klivusun üst 1/3 ve orta 1/3 bölümlerine ve petröz apekse lateralden yaklaşım için kullanılan girişimlerdir. Bu girişimler transvers-sigmoid sinüs bileşkesini mobilize ederek beyin sapına anterolateralden bakışı mümkün kılarlar. Bu kafa tabanı girişimleri klasik subtemporal ve suboksipital paramediyan girişimlere kıyasla daha geniş bir cerrahi koridor sağlar ve petroklival bölge lezyonlarında daha yüksek oranlarda total rezeksiyonu mümkün kılarlar. Oluşan komplikasyonlar sıklıkla geçici ve tedavi edilebilir olaylardır.
