The frontolateral approach has the advantages of both the pterional approach and conventional bifrontal approaches. 

====Indications====

===Olfactory groove meningioma===

The frontolateral approach allows quick and minimally invasive access to [[olfactory groove meningioma]] OGMs less than 4 cm in diameter, and also to tumors more than 4 cm in diameter without encasement of the anterior cerebral artery complex. Tumor size more than 4 cm in diameter and encasement of the anterior cerebral artery complex are limiting factors for the frontolateral approach if radical tumor removal is considered.
