Treatment and complications of mandibular fractures: a 10-year analysis

The surgical treatment and complications of patients with mandibular fractures in Amsterdam over a period of 10 years are analysed. Between January 2000 and January 2009 225 patients were surgically treated for a mandibular fracture (mean age of 32.6 (SD±14.6) years). A total of 426 fracture lines were identified. Of 213 dentate patients 29 patients were treated primarily with intermaxillary fixation (IMF). IMF combined with osteosynthesis was performed on 99 patients. Seventy-nine patients received IMF only per-operatively to make open reduction and internal fixation (ORIF) possible. Of 12 edentulous patients three patients were treated with Gunning splints. Nine patients were treated by manual reduction and internal fixation. A total of 1965 screws and 442 plates were used. Sixty (26.7%) patients presented with complications, including (transient) hyposensibility of the lip and chin (34 patients), dysocclusion (15 patients), infected osteosynthesis material (six patients) and temporomandibular dysfunction (five patients). Four patients needed surgical retreatment for correction of a dysocclusion. The results of this report are partly in line with other studies and provide important data for improving the treatment of the fractured mandible.
