Preoperative assessment of surgery using high-quality images can help surgeons to
achieve best result of treatment. With the advances in computer technology, interactive
multimodality fusion images have been developed. The use of fusion images as a preoperative
planning tool is described with its examples in illustrative cases of trigeminal neuralgia
and hemifacial spasm microvascular decompression (MVD). Interactive computer graphics
such as multimodality fusion method is a useful tool to preoperatively predict the
need of bone exposure and configuration of blood vessels with its correlation to cranial
nerves in MVD.
