Paper Abstract

Often within the clinical environment of a neurosurgical brain tumor procedure, the surgeon is faced with the difficulty of orienting the patient's head to maximize the success of removing the pathology. Currently, these decisions are based on the experience of the surgeon. The primary objective of this paper is to demonstrate how a mathematical model can be used to evaluate the different patient positioning for tumor resection therapies. Specifically, therapies involving gravity-induced shift are used to demonstrate how a series of candidate approaches to the tumor can result in significantly different deformation behavior of brain tissue. To quantitatively assess the advantages and disadvantages of potential approaches, three different midline tumor locations were used to evaluate for the extent of tumor exposure and the magnitude of tensile stress at the brain-tumor interface, both of which are reliable indicators of the ease of resection. Preliminary results indicate that the lateral decubitus position is best suited for midline tumors.
