Abstract |
The treatment of mandibular fractures by gunshot ranges from late conservative repair to more aggressive early repair in a single stage. Treatments that preserve bony architecture as much as possible should be used, minimising patient morbidity and the complexity of future surgeries. The purpose of this study was to use a systematic review to determine which method of treatment was most effective for mandibular fractures by gunshot. Searches were conducted on Medline via PubMed, Scopus, Central Cochrane, and Sigle via Open Grey up to August 2019. Four studies were eligible to this systematic review, considering the previously establish inclusion and exclusion criteria. A total of 211 patients were evaluated. The mandibular body was the region more fractured followed by the symphyseal/parasymphyseal region. The closed treatment with intermaxillary fixation (IMF) was the most used followed by open surgery with internal rigid fixation (IRF) and external fixator. Considering the total adverse effects, the meta-analysis showed no statistically significant difference between the IMF and IRF groups (p=0.840), but IMF showed five times less infection and IRF six times less malunion. The algorithm was delineated from the types of injuries by gunshot, proposing forms of treatment from initial stabilisation to functional rehabilitation with implant-supported prostheses. The treatment of mandibular fractures by gunshot remains a challenge for surgeons. There was a statistically significant prevalence of success in the IRF group, however this group was also associated with a higher index of infection than the IMF group. New studies with high methodological quality and larger numbers of participants are needed to offer more safety for surgeons who treat patients with mandibular fractures by gunshot. Language: en |
