title: Cordotomy for bilateral cord abductal paralysis.
abstract: OBJECTIVE
  To investigate the clinical effects of cordotomy on bilateral cord abductal paralysis.
  
  
  METHODS
  With unilateral cordotomy, we treated 4 patients with bilateral cord paralysis whose glottis size was about 2.0 mm to 2.5 mm. They were followed up for over one year.
  
  
  RESULTS
  One week after surgery, the tracheotomy tubes of all 4 patients were plugged and no dyspnea occurred during rest and mild action. Their voices were more hoarse than before surgery. After 3 months, the tracheotomy tubes were successfully decannulated, and in the following one year, their respiration was normal and then speech was clear, although their voices were still a little hoarse.
  
  
  CONCLUSIONS
  We suggest that cordotomy be one option in the treatment of bilateral cord abductal paralysis.
