Summary

Facial nerve injury after trauma often causes hearing loss. The mastoid segment is the most common site of injury, and a transmastoid surgical approach is recommended.

Area of Science:

  • Neurosurgery
  • Otolaryngology
  • Trauma Surgery

Background:

  • Post-traumatic facial nerve injury is a significant clinical challenge.
  • Hearing impairment, particularly conductive or mixed deafness, is a common sequela.
  • Accurate localization of the facial nerve injury site is crucial for effective management.

Purpose of the Study:

  • To analyze the characteristics of post-traumatic facial nerve injuries.
  • To identify key indicators for determining the injury site.
  • To recommend optimal surgical approaches for facial nerve paralysis.

Main Methods:

  • Retrospective analysis of 23 cases with post-traumatic facial nerve injury.
  • Evaluation of audiological findings, including conductive and mixed deafness.
  • Assessment of the utility of the Schirmer's test for localizing nerve injury.
  • Review of surgical interventions and outcomes.

Main Results:

  • A majority of patients presented with conductive or mixed deafness.
  • The Schirmer's test proved to be a valuable indicator for injury site determination.
  • The mastoid segment of the facial nerve was identified as the most frequently injured site (52% of cases).

Conclusions:

  • The transmastoid surgical approach is the preferred method for post-traumatic facial nerve paralysis.
  • A combined transmastoid and middle fossa approach may be beneficial for patients with a positive Schirmer's test, indicating higher injury localization.
