Background and objectives: The objective of the paper was to evaluate the surgical protocol following the presentation of contaminated/infected mandibular fractures and the treatment outcomes.

Methods: Out of 391 mandibular fracture trauma patients operated from 1st Jan 2002 to 31st Dec 2012, 33 had showed the infected mandibular fractures including soft and hard tissue involvement. 14-patients were with hard tissue infection, 8-patients were with soft tissue infection, 11-patients were with both hard and soft tissue infection.

Results: The parameters for success were Absence of clinical signs of infection Stable occlusion Normal range of motion Need of MMF Radiographic evidence of osseous union.

Conclusion: All patients met this criteria except one in which secondary bone grafting had to be carried out. The use of immediate bone grafting in reconstruction of clinically infected mandibular fractures is recommended in case of gross comminution.
