Facial nerve grafting outcomes improve when performed within one year of nerve deficit onset. The duration of preoperative facial nerve deficit significantly impacts functional recovery after grafting.

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Plastic Surgery

Background:

  • Facial nerve reconstruction is crucial for restoring function after injury or tumor removal.
  • Grafting techniques are employed when direct nerve repair is not feasible.
  • Predicting functional recovery after facial nerve grafting remains a challenge.

Purpose of the Study:

  • To evaluate the outcomes of facial nerve reconstruction using grafts.
  • To identify variables influencing final facial nerve functional recovery.

Main Methods:

  • Retrospective case review of 69 patients undergoing facial nerve grafting.
  • Analysis of preoperative facial nerve deficit duration and underlying causes.
  • Assessment of final facial nerve motor function using the House-Brackmann scale.

Main Results:

  • Among 56 patients with >1 year follow-up, 46.4% achieved Grade III and 25% achieved Grade IV recovery.
  • Patients with preoperative deficits >1 year had significantly lower recovery rates (19% reached Grade III).
  • The duration of the preoperative deficit was the primary factor affecting recovery.

Conclusions:

  • A preoperative facial nerve deficit duration exceeding one year is a critical cutoff point for achieving good functional recovery.
  • The underlying cause of the facial nerve lesion also significantly influences the final outcome.
  • Timely intervention is essential for optimizing results in facial nerve reconstruction.
