title: Facial nerve grafts: from cerebellopontine angle and beyond.
abstract: OBJECTIVE
  To review the outcomes from facial nerve cable grafting in a variety of pathologic conditions and to determine the possible causes of poor facial function after facial nerve grafting.
  
  
  METHODS
  A retrospective review of patients undergoing facial nerve grafts through a neurotologic procedure.
  
  
  METHODS
  This study was performed at a university-based tertiary referral center.
  
  
  METHODS
  All 27 patients undergoing a neurotologic procedure that required a facial nerve graft from 1982 to 1997 were reviewed. Fourteen patients had grafts from the facial nerve stump at the brainstem.
  
  
  METHODS
  All patients had facial nerve function determined by the senior neurotologist and through use of historical data and photographs.
  
  
  METHODS
  A facial nerve repair recovery score was developed for facial nerve transection and repair. The House-Brackmann scale was found to be inappropriate for transected and repaired nerves.
  
  
  RESULTS
  Facial function was found in 23/25 (92%) patients with at least 8 months follow-up. Statistical analysis revealed no significant correlation between graft length and recovery score. Patients who had the nerve grafted to a site distal to the meatal foramen had a mean outcome that was nearly one grade level better than those with an anastomosis proximal to the meatal foramen (i.e., at the brainstem), but this did not reach statistical significance.
  
  
  CONCLUSIONS
  Facial nerve grafting is an effective way of restoring facial motor function. A new facial recovery grading scale is proposed for repaired or grafted facial nerves.
