This review investigating whether the presence of third molars during sagittal split osteotomy of the mandible increases the risk of complications included 15 studies. The findings suggests no statistically significant relationship between the presence of 3Ms and complications. However a majority of the studies were retrospective with 13 studies being considered to be at high risk of bias so the certainty of the evidence is considered to be very low.

This review of platelet-rich fibrin (PRF) to reducedpostoperative complications following lower third molar surgery included 6 RCTs.
The findings are consistent to other reviews finding that PRF derivative may lead to improvements in postoperative outcomes from third molar surgery but the amount of evidence is limited.
This review of whether the presence of the lower third molar in the mandibular angle fracture line is associated with postoperative complications included 34 studies. The quality of teh included studies was low to very low so the findings should be viewed cautiously.

This review of the effectiveness of platelet-rich fibrin (PRF) in reducing postoperative complications of third molar surgery included 10 small RCTs suggesting that PRF may reduce but not prevent some complications.

This review of perioperative systemic corticosteroids on clinically important outcomes in patients undergoing orthognathic surgery identified 8 small RCTs. A reduction in facial oedema was seen in those receiving systemic corticosteroids. However the quality of the studies is limited and there is lack of evidence on other outcomes or adverse effects.

This Cochrane review did not identify any randomised controlled trials that evaluated the effects of different interventions for the treatment of post-extraction bleeding. Clinicians must use their clinical experience to determine the most appropriate means of treating this condition, depending on patient-related factors.

10 RCTs were included in this review of preoperative antibiotics for removal of third molars. The use of antibiotics significantly reduced the odds of surgical site infection or alveolar osteitis (OR = 0.30; 95% CI, 0.19 to 0.47; P≤.00001)

This is one of a series of reviews that has looked at postoperative complications following different treatments for mandibular fractures. This review focuses on anterior mandibular fractures with the findings suggesting that lag screws and single miniplate plus an arch bar were superior to 2 miniplates

This review looked at which internal fixation method for mandibular fractures resulted in lowest complication rate. 20 studies were included and they found use of 1 miniplate is superior to using 2 ; and the transbuccally placed lateral miniplate was better than one placed on the external oblique ridge
