A 45-year-old man is diagnosed with Iatrogenic facial nerve palsy for 1wk. If ENoG shows as picture, what is the recommended next step?

• Serial ENoG

• Immediate surgical decompression

• Physical therapy

• No intervention, as the nerve will regenerate on its own

3. A 40-year-old male undergoes mastoidectomy for cholesteatoma. During surgery, the surgeon suspects facial nerve exposure in the mastoid segment.

Which structure should the surgeon identify to confirm the location of the facial nerve?

• Horizontal semicircular canal
  
  

• Henle spine

• Pyramidal eminence

If the nerve is found to be dehiscent but intact, what is the best management strategy?

• Ignore the finding and continue surgery

• Perform facial nereve decompression

• Cover the exposed nerve with fascia

• Proceed with complete nerve transection to prevent future damage
  
  

If the nerve is found to be partial transection >50%

, what is the best management strategy?

• Perform facial nereve decompression

• Cover the exposed nerve with fascia

• Proceed with complete nerve transection to prevent future damage
  
  

• nerve repair via direct end to end anastomosis
  
  

6.A 7-year-old child has complete left-sided facial weakness after cochlear implant. The surgeon reviews the intraoperative records and finds no signs of nerve transection.

What is the most appropriate initial postoperative management for this patient?

• Immediate explore and decompression facial nerve
  
  

• High-dose corticosteroids and close monitoring

• Orders an electroneurography (ENoG) test

• No intervention, as recovery is unlikely
  
  

A 30-year-old man presented with right facial wound and facial paralysis (HB Grade VI) . What is the most proper management
