This is a meta-analysis of maxillofacial injuries arising from riding a bicycle. The incidence of maxillofacial fractures in cycling accidents varies from 3-20% and, whilst the effectiveness of helmets in preventing traumatic brain injuries is well known, their protective effect on maxillofacial injuries is uncertain. They found that wearing a helmet whilst riding a bicycle decreased the risk of sustaining a maxillofacial injury with an odds ratio of 0.682 or risk reduction of 32%. They criticise the poor quality of the included studies and weren’t able to differentiate between the types of maxillofacial injuries. Nonetheless, they outline the positive effect of introducing legislation for compulsory helmet wear or at least increasing its use along with touching upon possible benefits in e-bike accidents.
