Quantitative proteomic analysis of cerebrospinal fluid from patients with idiopathic facial nerve palsy.

Idiopathic facial palsy (IFP) accounts for over 60% of peripheral facial palsy (FP) cases. The cause of IFP remains to be determined. Possible etiologies are nerve swelling due to inflammation and/or viral infection. Here, we applied an integrative mass spectrometry approach to identify possibly altered protein patterns in the CSF of IFP patients.
