A comparison of outcomes between immediate and delayed repair of mandibular fractures.

Medical records of patients treated with surgical repair of mandible fractures by the otolaryngology and plastic surgery departments at a level 1 trauma centre were obtained and reviewed. Two study groups were compared: patients treated within 72 h of the injury and those treated after this time period. Patient demographics, time to repair, fracture types, substance abuse history, etiology, surgical management, complications and length of hospital stay were assessed. The complication rate was 41% (n=7) within the immediate group and 38% (n=6) within the delayed group (P=0.56). Complications were prevalent in patients with history of substance abuse in both groups. Complication rates did not increase when repair of mandible fractures was delayed beyond 72 h, while substance abuse was a factor in increasing complications rates. Outpatient triage with elective repair of isolated mandibular fractures appears to be more cost-effective than admission with inpatient management.
