There was some low quality evidence that a single dose of corticosteroid administered prior to surgery might reduce swelling and bruising over the first two days after surgery, but this advantage was not maintained beyond two days. One study, with 40 participants, showed that high doses of corticosteroid decreased both swelling and bruising between the first and seventh postoperative days. The usefulness of these results is uncertain and there is currently no evidence regarding the safety of the treatment. Five trials did not report on harmful (adverse) effects; four trials reported that there were no adverse effects; and one trial reported adverse effects in two participants treated with corticosteroids as well as in four participants treated with placebo. None of the studies reported recovery time, patient satisfaction or quality of life.
