title: Selective or radical surgical strategy in functional autonomy of the thyroid in endemic areas.
abstract: BACKGROUND
  The purpose of the research is to compare two surgical methods in the treatment of functional autonomy of the thyroid regarding postsurgical complications and functional results.
  
  
  METHODS
  212 patients were examined--divided into two groups. Group 1 (n = 148)--in which selective thyroid resection have been done and Group 2 (n = 64)--in which radical resection have been undertaken.
  
  
  RESULTS
  For both groups the following postoperative complications have been determined: In 4 (1.8%) patients transitory recurrent palsy is determined and in 1 (0.5%) patient-permanent recurrent palsy. The frequency of the transitory hypoparathyroidism is 7.5% (n = 16) and that of the permanent hypoparathyroidism is 0%. 148 patients from the two groups were followed up with respect to the functional results obtained at the eight postsurgical week and from 1 to 7 years after the operation. In the selective group (eight postsurgical week) 3 from the patients were with hyperthyroidism and 4 with hypothyroidism. From 1 to 7 years after the operation the following functional results have been determinated: in 7 patients relapse of the hyperthyroidism, in 8 patients new hypothyroidism and in 3 patients- morphological recurrence In radically operated patients the frequency of the postsurgical hypothyroidism during the 8 postsurgical week was 50% (n = 26). For the period from 1 to 7 years after the operation the following functional results were observed: 1 patient with relapse of hypothyroidism, 11 patients with new hypothyroidism. Not one morphological recurrence was observed.
  
  
  CONCLUSIONS
  The residual and recurrent hyperthyroidism are related to the insufficient extent of resection. A functionally confirmed surgical strategy has been imposed in the endemic areas striving to remove all nodular structures at the same preserving the normal thyroid tissue.
