Increased flammability hazard when ionic liquid [Cmim][Cl] is exposed to high temperatures.

Industrial use of ionic liquids may require exposure to high temperatures. We demonstrate that such applications may result in an increase in flammability hazard due to chemical decomposition. The ionic liquid, 1-hexyl-3-methylimidazolium chloride ([Cmim][Cl]), was selected as the study sample.

Objective: To provide a valuable imaging anatomic method for operation of the posterior transpetrosal approach and accurate positioning among relative structures in order to reduce the incidence of surgical complications.

Methods: The clinical information of 119 adult cases (238 sides) was analyzed. All the cases underwent 16 layer helix CT scanning and three-dimensional image reconstruction of skull base without a skull base disease.
