title: [The value of frozen section examination in thyroid surgery].
abstract: OBJECTIVE
  To research the value of frozen section examination for intraoperation diagnosis of thyroid nodule and determination of extent of thyroidectomy.
  
  
  METHODS
  A retrospective evaluation of a group of 1 057 patients with thyroid nodular disease was analyzed. The group was divided into frozen section examination group (FS group) and non-frozen section examination group (NFS group).
  
  
  RESULTS
  There were 750 cases in FS group. The diagnosis made by frozen section examination was carcinoma in 117; benign lesion in 626. Diagnosis was deferred in 7 patients. The final pathology diagnosis was carcinoma in 127; benign lesion in 623. The sensitivity, specificity, accuracy and disaccord rate of frozen section examination were 95. 9%, 100. 0%, and 98. 4%, and 1. 6%, respectively. There were 307 cases in NFS group, and the final pathology diagnosis was carcinoma in 30; benign lesion in 277. The disaccord rate with clinical diagnosis was 9. 77%. The binomial distribution analysis indicate that the difference of disaccord rate between the FS group and the NFS group was remarkable ( P <0. 01).
  
  
  CONCLUSIONS
  Frozen section examination has value in diagnosing the thyroid nodular, and is capable of determination of the extent of thyroidectomy.
