Facial Nerve Tests

3.10.1 Describe some non-electric topographical tests of the facial nerve for injury.

3.10.2 Describe the NET and MST. When and how can they be useful? Limitations?

3.10.3 Describe the EnoG and how it is done. When are the results most reliable and why?

3.10.4 Describe EMG. Give us some sample EMG waveforms and tell us what they mean.

3.10.5 Discuss this diagram in detail.

3.10.6 Discuss the role of EMG/EnoG in acute and chronic cases of facial nerve injury.

3.10.7 A 35 yo female patient has recovered to a House Brackmann Grade III after suffering from Bell's palsy 9 months ago. The MRI shown was ordered because of her incomplete recovery. What is the role of surgical excision and grafting, decompression, versus conservative treatment with facial nerve exercises? Discuss the role of an MRI in patients with acute, chronic and progressive facial nerve paresis.

3.10.8 Intra-operative facial nerve monitoring....what are the indications? Is it cost-effective?

3.10.9 A patient presents to the trauma bay after a closed head injury. He has a unilateral facial nerve paralysis and a CT scan confirms a temporal bone fracture. The family wants your expert opinion on the prognosis and return of facial nerve function. Discuss the latest literature on decompression/grafting. Where is the most likely site of facial nerve injury with a temporal bone fracture?
