Magnetic resonance tractography of the cranial nerves is
a promising tool. Yet, in order to validate the quality
of quantitative data yielded from this technique, the
course of nerve fibres must be confirmed surgically.
This prospective study is the first work that assessed
the feasibility and reliability of extracranial facial
nerve magnetic resonance tractography using in vivo
data, based on surgical photos and per-operative nerve
stimulation. We successfully identified facial nerve, in
relation to the parotid tumors, in all patients and
performed quantitative microstructural analysis for 52
facial nerves. The outcome would be to aid future
medical studies examining nerve dysfunction.
