To review the literature on the effect of different surgical approaches on facial nerve injuries.The present systematic review addresses the following focus question: Is the facial nerve at risk following surgical correction of mandibular condylar fracture? Electronic and manual literature searches were conducted on databases:PubMed, ScienceDirect and Google scholar,Cochrane and clinicaltrials.gov for studies published until July 2020 to collect information about the effect of different surgical approaches on facial nerve injuries.Systematic literature review was performed following the prisma guidelines to identify studies. Quantitative retrospective and prospective studies,controlled trials,controlled clinical trials were included;case reports and review articles were excluded from this systematic review. 1500 articles published till July 2020 was identified. 116 articles met inclusion criteria. After applying exclusion criteria seven articles were shortlisted.The level of heterogeneity was observed to be less than 50%, between all parameters for all studies making publication bias to be minimum.On comparing various studies statistically using Z-test for all parameters,it was observed that level of significance was significant for various findings like Displacement/Dislocation of fracture and transient facial nerve weakness was found to be statistically significant between all studies (p-value <0.05). Odd ratio, relative ratio and 95% CI was derived for all parameters recorded for various studies. Due to less number of subjective studies, and variability in study designs and lack of reporting on confounding factors,definitive conclusions on effect of various surgical approaches on facial nerve injury cannot be drawn Future well-designed long-term randomized controlled trials are necessary to reveal the necessary correlation between both the parameters.
