RESUMEN
The ojective of this study was to compare the complications [infection and non union] when fractures through the angle of the mandible are treated with a single noncompression miniplate versus 2 noncompression miniplates. 300 patients were randomly divided in two groups, 150 patients in each. Group A was treated by single non compression miniplate plate at superior borber of angle of mandible using intraoral approach. Group B was treated by two noncompression plates one at superior border as in group A, and other plate at lower border using extra oral approach. Patients were assessed for infection and non union on 21st, 45th and 60th days after the procedure. Mean age of patients in Group-A was 35.87 +/- 1.90 and in Group-B mean age of patients was 31.30 +/- 3.45 years respectively. Gender distribution showed that there were 241 [80.34%] [Group-A=124, Group-B=117] male and 59 [19.67%] female patients [Group-A=26, Group-B=33]. There were 10[6.67%] patients in Group-A and 22[14.67%] patients in Group-B who got infection at fracture site at 21st day.. At 45th day 6 [4%] patients in Group-A and 17[11.33%] patients in Group-B had infection. At 60th day infection was present in 10 [6.67%] patients and in Group-A only 2 patients had infection. This study shows that there are less chances of Infection when the patients are treated with one miniplate as compared to two miniplates for the treatment of displaced mandibular angle fractures
