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
