Incidence, aetiology, treatment outcome and complications of maxillofacial fractures. A retrospective study from Northern Greece

Aim: To analyse the pattern of maxillofacial injuries and treatment outcomes in Northern Greece. Methods: A tertiary referral single centre hospital; retrospective chart review. Demographics, aetiology, fixation technique (Rigid Internal Fixation: RIF; Maxillomandibular Fixation: MMF) post-surgical infections, aesthetics and occlusion were recorded. Results: One thousand and ten males and 229 females were operated between 1998 and 2008. Mean age was 29.6 +/- 13. Mean number of plates per patient was 3.96 +/- 2.28. For those with midfacial fractures (n = 379) mean was 4.02 +/- 2.05. For those with mandibular fractures (n = 333), mean was 2.74 +/- 0.94 while those with combined mandible and midface fractures (n = 216) were treated using 5.74 +/- 2.87 plates per patient. Among those treated with plates, an unadjusted 22% increased risk for post-surgical infection per plate used (OR = 1.22, 95%CI: 1.13-1.32) was found. Patients with mandibular fractures were more satisfied with their post-surgical facial appearance in contrast to those with midfacial or combined midfacial and mandibular fractures. Female patients were less satisfied with their post-surgical facial appearance than males. Discussion: This study verified a young males predominance, a shift towards more assault related fractures especially in females and similar post-surgical results for MMF and RIF modalities in mandibular fractures. In those patients treated with RIF, placement of fewest plates possible to obtain stability better serves aesthetics at the same time reducing risk for post-surgical infections and malocclusion.
