title: Delayed facial nerve paralysis post middle ear surgery: herpes simplex virus activation.
abstract: Delayed facial nerve paralysis post middle ear surgery: herpes simplex virus activation.
  
  
  OBJECTIVE
  Facial nerve paralysis following middle ear surgery is a nightmare for the otology surgeon. Usually this is caused by surgical trauma or local anaesthetic use. It is uncommon to see onset of facial nerve palsy more than 72 hours following the surgery.
  
  
  METHODS
  We report a case of facial nerve paralysis appearing 11 days following a successful canal wall-down mastoidectomy.
  
  
  RESULTS
  Viral screening for Herpes Virus type 1 confirmed the viral aetiology of the delayed facial paralysis.
  
  
  CONCLUSIONS
  When an ipsilateral facial nerve palsy appears more than 72 hours after an uneventful middle ear procedure, without symptoms of any infection, suspect a viral reactivation.
