Background Bell’s palsy (BP) is the most common form of acute facial nerve disorder and is characterized by rapid onset peripheral facial palsy of unknown etiology. Purpose To explore the diagnostic value of dynamic contrast-enhanced (DCE) magnetic resonance imagine (MRI) in patients with BP particularly in involved segments. Material and Methods A retrospective analysis was performed on the patients with BP who underwent routine MRI examinations and volumetric interpolated breath-hold examination (VIBE) sequence-based DCE-MRI before surgery in our department from January 2015 to July 2020. DCE-MRI data postprocessing was performed on Siemens Workstation Extended MR Work Space 2.6.3.5. Statistical analyses were performed using SPSS®v.19.0. The inter-observer reliability was evaluated with kappa identity test and McNemar’s test. Results Twenty-three patients were included. On conventional contrast-enhanced MRI, the two observers were inconsistent in their diagnosis of lesion segments of facial nerve (Kappa 0.426, P = 0.009). Compared to the results of the surgery, the diagnostic consistency of both observers was general (Kappa 0.476, P < 0.001 and Kappa 0.430, P < 0.001, respectively). The diagnostic results of DCE-MRI for lesion segments of the facial nerve were consistent between the two observers (Kappa 0.929, P < 0.001). Compared to the results of the surgery, the diagnostic consistency of both observers was good (Kappa 0.753, P < 0.001 and Kappa 0.731, P < 0.001, respectively). Conclusion Compared to conventional MRI, DCE-MRI has good stability and repeatability in the diagnosis of the lesion segments of the facial nerve as well as a good specificity and accuracy.

AbstractIn Bell’s palsy, electrodiagnosis by electroneurography (ENoG) is widely used to predict a patient’s prognosis. The therapeutic options for patients with poor prognostic results remain controversial. Here, we investigated whether early intervention with intratympanic steroid therapy (ITST) is an effective treatment for Bell’s palsy patients with poor electrodiagnostic test results (≤ 10% electroneurography value). Patients in the concurrent ITST group (n = 8) received the standard systemic dose of prednisolone (410 mg total) and intratympanic dexamethasone (16.5 mg total) and those in the control group (n = 21) received systemic prednisolone at the standard dose or higher (average dose, 605 ± 27 mg). A year after onset, the recovery rate was higher in the ITST group than in the control group (88% vs 43%, P = 0.044). The average House-Brackmann grade was better in the concurrent ITST group (1.13 ± 0.13 vs 1.71 ± 0.16, P = 0.035). Concurrent ITST improves the facial nerve outcome in patients with poor electroneurography test results, regardless of whether equivalent or lower glucocorticoid doses were administered. This may be ascribed to a neuroprotective effect of ITST due to a higher dose of steroid reaching the lesion due to dexamethasone transfer in the facial nerve.

Simplex Virus

We have been the first to succeed in producing an acute and transient facial paralysis simulating Bell's palsy, by inoculating herpes simplex virus into the auricles or tongues of mice. The KOS strain of the virus was injected into the auricle of 104 mice and the anterior two thirds of the tongue in 30 mice. Facial paralysis developed between 6 and 9 days after virus inoculation, continued for 3 to 7 days, and then recovered spontaneously. The animals were painlessly sacrificed between 6 and 20 days after inoculation for histopathologic and immunocytochemical study. Histopathologically, severe nerve swelling, inflammatory cell infiltration, and vacuolar degeneration were manifested in the affected facial nerve and nuclei. Herpes simplex virus antigens were also detected in the facial nerve, geniculate ganglion, and facial nerve nucleus. The pathophysiologic mechanisms of the facial paralysis are discussed in light of the histopathologic findings, in association with the causation of Bell's palsy.
