Text

Objective: Optical navigation has become a standard naivgation technology for a broad range of neurosurgical cranial and spinal interventions. In contrary, electromagnetic navigation (EMN) bears some significant advantages for some kinds of neurosurgical cranial interventions. This is especially the kind for inraventricular or intracystic fenestrations, as well as for endoscopic intra- and parasellar surgry.

Methods: For the EMN, a small, disposable universal frame is attached tot he patients head (by screws or by glue). The referentiation is performed as for a routine optical navigation. The accuracy is comparable tot hat of optical navigation.

Results: We have used the EMN in more than 70 procedures. For intrasellar endoscopic interventions, the EMN hast he advantage, that the patients head has not to be fixed in a mayfield fixation. Additionally, because of a limited space in transnasal approaches, the EMN bears advantages due to the fact that the EMN navigational pointers are very small and don´t need much space in the nasal cavity. For intraventricular or intracystic endoscopic procedures, these probes can be inserted directly into the endoscope. Therefore, a direct and not only virtual navigation is possible.

Conclusion: EMN is especially useful for endoscopic transnasal and intraventricular – intracystic interventions.

Additionally in neonatal interventions navigation is possible even in very young children, where fixations in a Mayfield clamp would not be possible.
