Analysis of demographics and post operative complications relating to mandibular angle fractures in a National Maxillofacial Unit
Objectives: Objectives: Mandibular angle fractures (MAF) have an increased risk of incurring complications compared to other mandibular fractures. These fractures are associated with assaults and a younger, predominantly male age group. There are a recognised variety of options for treatment of MAF, none of which have not demonstrated a convincing superiority. This study aims to establish the incidence of post-operative complications and reoperation of isolated MAF in the National Maxillofacial Unit, St James Hospital. Methods: Methods: A single centre, retrospective cohort study was conducted for a single calendar year. Patients undergoing open reduction with internal fixation with an isolated MAF and no other facial fractures were identified from a retrospectively obtained database of mandibular fractures. Complications were scored as minor (treated as outpatients) and major (involving a return to theatre). Results: Results: This cohort study included 45 patients. The average age was 27.3 (SD=7.7) and 84% (38/45) were male. All patients were treated in a similar fashion, with standardised pre- surgical antimicrobial prophylaxis. Intermaxillary fixation was employed according to surgeon preference. A comparatively low rate of complications (11.1%) and a low rate of reoperation (1.8%) is reported, along with a significant role of smoking in complications (p=0.022). A non-significant association was noted between complications and male gender (p=0.28) as an aetiological factor. No association was noted between surgical approach and complication rates (p=0.44). Conclusions: Conclusions: Review of the data from this study confirms that complication rates for patients attending the National Maxillofacial Unit are similar to or better than that of international studies.
