Treatment of mandibular fractures with rigid osteosynthesis: using the AO system
1Maxillo-facial Surgery Division, Centre Hospitalier Universitaire Vaudois, Lausanne, Switzerland.
Purpose:
This study evaluated the results achieved in the surgical treatment of all mandibular fractures at two university centers using the 2.7 AO mandibular system.
Patients And Methods:
A total of 227 patients presenting with 180 single fractures and 47 with double fractures (274 osteosyntheses) were included in this prospective study.
Results:
During a mean follow-up of 27.5 months (minimum, 12 months), an overall complication rate of 7% was observed. No infection justified early removal of the osteosynthesis material.
Conclusions:
The systematic use of the technique recommended by AO for treating mandibular fractures, performed by thoroughly experienced operators on a compliant population, results in a low rate of complications and an early return to normal function.
