Venous saving in olfactory meningioma's surgery.
Bifrontal craniotomy and interhemispherical approach, usually used to remove olfactory groove meningioma, does not allow a view of posterior pole, which is very important in the surgical management of this neoplasm, and, provides for an anatomical sacrifice of frontal bridging veins, not without complications as a result of venous infarction. From 1975 the pterional approach was performed on 20 patients with olfactory meningioma, with good results in 90% of cases. This approach presents several advantages over bifrontal craniotomy and, in order to minimise surgical damage, it avoids planned sacrifice of venous vessels.
