Group-A received prophylactic 4 mg submucosal dexamethasone intraoral injection and Group-B acted as control group. Facial swelling and trismus were assessed at baseline, 2nd and 7th postoperative days. Data was analyzed using SPSS-10.ResultsThere were 35 (70%) males and 15 (30%) females in group-A and 34 (68%) males and 16 (32%) females in group-B. Surgical time ranged from 30 - 50 minutes (mean = 40.62 ± 4.886 minutes) for group-A and 33 - 50 minutes (mean = 42.12 ± 4.543 minutes) for group-B.
