Objectives: A plethora of surgical strategies have been described to reach deeply lesions situatedwithin the third ventricle, including the Rosenfeld or anterior transcallosal interfoniceal approach(TAIF). Firstly, introduced in 2001, it consists of a small callosotomy followed by the midlinetransseptal dissection of fornices to enter the roof of the third ventricle. The aim of thismicrosurgical anatomy study is to describe and show each stage of the surgical procedure, focusingon the possible trajectories to anatomic landmarks.Participants: A total of twenty adult cadaveric specimens were used in this study. Using x3 to x40magnifications the surgical dissection was carried out in a stepwise fashion and the transcallosalanterior interforniceal approach was performed, analyzed and described.Results: In five specimens out of ten a cavum septum pellucidum was depicted. In five cases out oftwenty after the callosotomy the lateral ventricular cavities were reached. Different orientation of themicroscope allowed the defining of three surgical trajectories to visualize the region of interestwithout exposing important functional areas.Conclusion: The TAIF represents a minimally invasive approach to the third ventricle; its trickysurgical steps make appropriate anatomical dissection training, essential to become confident andskilled in performing this approach.
