title: Surgical timing for facial paralysis after temporal bone trauma.
abstract: OBJECTIVE
  To explore surgical timing of facial paralysis after temporal bone trauma.
  
  
  METHODS
  The clinical data of the patients with facial paralysis after temporal bone trauma who underwent subtotal facial nerve decompression were retrospectively collected, and 80 cases followed-up for one year were enrolled in the study. They were divided into different subgroups according to the age, onset, and interval between facial paralysis and surgery, and the outcomes of facial nerve between different subgroups were compared.
  
  
  RESULTS
  The number of patients who achieved good recovery of HB Grade I or II was 52 of 80 (65.0%). 43 of 66 cases (65.2%) in the younger group had good recovery of facial nerve in contrast to 9 of 14 cases (64.3%) in the elderly group, without significant difference (p>0.05). 9 of 13 cases (69.2%) in the delayed onset group had good recovery, while 43 of 67 cases (64.2%) in the immediate onset group had good recovery, without significant difference (p>0.05). The good recovery rate of the <1month group was statistically higher compared to the 3-6months group or the >6months group (P<0.05), while the good recovery rate of the <1month group was not statistically higher than that of the 1-2months group or the 2-3months group (P>0.05).
  
  
  CONCLUSIONS
  This study demonstrated that the good recovery rate of facial paralysis after temporal bone trauma was uncorrelated with age and onset. It was better to perform surgical decompression within 3months after facial paralysis.
