On the first day, 2nd day, and 7th day after operation, facial swelling, trismus, and pain were evaluated. On the first day, the difference in the volumetric change of facial swelling was 45%(p<0.05) as measured by Holland s nine pointers facebow. The trismus was reduced by 28%(p<0.01) in test froup. Pam assessed with Visualanaloguescale(VAS) was reduced by 33%(p<0.001) by dexamethasone.
