Because the base of the skull has proven to be one of the most challenging regions of the body to access, treatment options were once limited for patients with tumors or lesions in this area. However, with recent advancements and breakthroughs in treatment, patients with skull base tumors now have an array of surgical options that can help them return to leading a normal and active life. The Endoscopic Endonasal Approach (EEA) is an innovative surgical technique used to remove brain tumors and lesions-some as large as softballs-all through the nose.

This issue will cover chiari malformation in both children and adult populations. In the past, it was estimated that the condition occurs in about one in every 1,000 births. However, the increased use of diagnostic imaging has shown that CM may be much more common. Complicating this estimation is the fact that some children who are born with the condition may not show symptoms until adolescence or adulthood, if at all. CMs occur more often in women than in men and Type II malformations are more prevalent in certain groups, including people of Celtic descent.
