OBJECTIVE: The goal of this project was to report the complications associated with mandibular angle fractures and identify variables affecting their occurrence.
METHODS: We retrospectively reviewed the charts of patients with a mandibular angle fracture treated at the Centre hospitalier universitaire de Québec between 2009 and 2013.
RESULTS: Seventy-eight patients (73 males) aged 15-59 years (mean 25.2 years) met our inclusion criteria. A wisdom tooth was present in 85.9% (n = 67) of the cases and it was removed 62.7% (n = 42) of the time. Thirty-four patients (43.6%) had other mandibular fractures. Most fractures were fixated with a sagittal split osteotomy plate (n = 32; 41.0%) or a 2.0-mm plate on the lateral aspect of the mandible (n = 20; 25.6%). The overall complication rate was 42.3% (n = 33); of these 37.2% were infections, 26.9% involved plate removal and 6.4% were associated with non-union. Older patients had more infections (p = 0.03) and more plates removed (p = 0.03). When a wisdom tooth was extracted, more infections (p = 0.04) and overall complications (p = 0.02) were observed.
CONCLUSION: This study confirms that, when treating a mandibular angle fracture in a healthy patient, it may be beneficial to leave a wisdom tooth in the line of fracture in place, if there is no indication to remove it.
