title: [Thyroid hormone level change in patients undergoing oral and maxillofacial surgery].
abstract: OBJECTIVE
  To study the changes of thyroid hormone level in patients undergoing oral and maxillofacial surgery before and after operation, in order to provide some evidences for postoperative treatment and recovery.
  
  
  METHODS
  60 cases with oral and maxillofacial operations under general or local anesthesia were assayed by radioimmunoassay for hormone levels changes of T3 ,T4, r T3 and TSH in serum before operation and on the first, forth and seventh day after operation. SPSS10.0 software package was used for one way ANOVA.
  
  
  RESULTS
  Compared to preoperative levels, T3, T4 and r T3 (P<0.01) as well as TSH (P<0.05) in patients receiving operations under general anesthesia on the first, forth and seventh day postoperatively decreased significantly, while the changes of thyroid hormone level in patients receiving operations under local anesthesia before and after operation were not significantly different.
  
  
  CONCLUSIONS
  Thyroid hormone level change in patients who underwent oral and maxillofacial surgery may be related to the type of operation and anesthesia.
