title: Management of Grave's disease is improved by total thyroidectomy.
abstract: BACKGROUND
  A retrospective analysis was performed on 267 consecutive patients with Graves' disease (GD). The principal aim of this study was to evaluate the risk for recurrence and complications when changing the surgical method from subtotal (ST) to total thyroidectomy (TT).
  
  
  METHODS
  Information from 267 consecutive patients operated on for GD between 2000 and 2006 was collected at Uppsala University Hospital (143) and Falun County Hospital (128). There were 229 women and 38 men. Four patients were operated on twice. A total of 40 STs and 229 TTs were performed. Results were compared to those of a previous cohort from the same hospital, with a majority of STs (157/176) performed from 1980 to 1992.
  
  
  RESULTS
  The risk for relapse of GD was reduced from 20 to 3.3 % after the shift from ST to TT. In terms of surgical complications, 2.2 % demonstrated permanent vocal cord paralysis and 4.5 % had persistent hypocalcemia, not significant when compared to the previous cohort. In spite of TT, there were four recurrences, all due to remnant thyroid tissue high up at the hyoid bone. Changing the surgical method did not affect postoperative progression of dysthyroid ophthalmopathy (DO, 7.0 vs. 7.5 %). There were no differences in outcome with respect to which hospital the patients had their operation.
  
  
  CONCLUSIONS
  Change from ST to TT dramatically reduced the risk for recurrence of GD without increasing the rate of complications. TT is not more effective than ST in hampering progression of DO as has been advocated by some. Careful surgical dissection up to the hyoid bone is necessary to avoid recurrence.
