Olfactory groove meningiomas were removed mainly through two different surgical approaches. Even in large tumors, high rates of total tumor resection could also be achieved with low recurrence rates using the simple and minimally invasive frontolateral approach. In recent years, we have preferred to use the frontolateral approach, which provides quick access to the tumor with less brain exposure while still enabling total tumor removal with a low morbidity rate and no mortality.
From 1978 through 2002, tuberculum sellae meningiomas were removed microsurgically using three different surgical approaches. Considering the operative morbidity and mortality, the frontolateral and pterional approach provided remarkable improvement compared with the bifrontal approach. These approaches allowed quick access to the tumor and were minimally invasive with less brain exposure, but still engendered high rates of total tumor removal. By comparison, the frontolateral approach provided the best results concerning visual outcome while representing the least invasive surgical approach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
