Management of mandibular fractures associated with lower third molar extraction

Abstract

Surgical removal of third molars is a common procedure performed by bucomaxilos surgeons, and accidents and complications can be related to this procedure. Mandibular fracture is an uncommon accident, but it has great potential to generate morbidity in patients. Because of this, the importance of an early approach after trauma is evident, as well as the subsequent follow-up and correct determination of treatment. In this sense, this objective is to investigate in the literature the existing protocols for the treatment of transverse mandibular fractures associated with the extraction of lower third molars. To this end, a systematic exploratory and descriptive literature review were conducted in the Pubmed database using the descriptors mandibular fracture, extraction and treatment. The searches were performed with a time restriction from 2016 to 2021. Of the 18 articles compatible with the proposal, 6 articles passed the inclusion and exclusion criteria. Of these, the analysis of most authors is clear in referring to third molar extractions as a factor for mandibular fractures and mentioning which treatment protocol to follow if a fracture occurs. It is concluded that closed or open reduction are possible approaches, however there is a preference for open reduction by extraoral or intraoral access with rigid internal fixation, since it eliminates the period of maxillomandibular block, facilitating the return to function.
