Introduction: We report functional and clinical outcomes following use of a preauricular long-corniform incision for open reduction and internal fixation (ORIF) of mandibular condylar fractures.
Materials and methods: Patients with mandibular condylar fractures who underwent ORIF via a 120 preauricular long-corniform incision were included in the study. A total of 78 patients (100 condyles) were included. Follow-up occurred 10 days and 1-6 months after surgery, and included assessments of clinical, functional outcome, complications, and bone fusion.
Results: There were 38 high neck, 26 low base, and 35 diacapitular condylar fractures. All measures of functional outcome significantly improved over time after surgery regardless of fracture type (all P < 0.001). The vast majority of patients in all fracture type groups had good occlusion (>= 88.5%), no pain (>= 89.5%), and anatomical reduction 10 days after surgery (>= 81.6%). Fracture healing was complete in all patients after 6 months. There were no long-term complications and all patients were satisfied with their postoperative appearance.
Conclusions: Our findings suggest that a preauricular long-corniform incision provides a good visual field during surgery, and allows for effective ORIF of mandibular high neck, low base, and diacapitular condylar fractures, with positive outcomes and minimal postoperative complications.
