    Objective: This review addresses a clinical research question related to lower third molar surgery (L3MS): does the combination of pre-emptive low-dose ketamine with local anesthesia (KLA) reduce postoperative complications compared with local anesthesia (LA) alone? Material and methods: A systematic literature search was performed to identify eligible articles by electronic searches of PubMed, Cochrane Central Register of Controlled Trials, EBSCO Library, Web of Science and grey literature through June 2019 without data or language restrictions. We analyzed all randomized controlled clinical studies (RCTs) comparing use of KLA with use of LA in L3MS regarding pain, swelling, and trismus outcomes. The quality of evidence was rated according to Cochrane’s tool for assessing risk of bias. Results: Five RCTs encompassing 230 extraction sites (KLA = 115, LA = 115) were included in this study. The standardized mean difference (SMD) with the 95% confidence interval (CI) was used to synthesize the results. The data show that there were significant differences between the two groups in post-operative pain (SMD -1.464, 95% CI -1.683 to -0.949, p= 0.001) and swelling (SMD -0.450, 95% CI -0.758 to -0.142, p= 0.004, all low quality evidence). However, there was no significant difference in the trismus (SMD -0.754, CI -1.487 to -0.022, p = 0.043, very low quality evidence). Conclusion: The combination of pre-emptive low-dose ketamine with LA significantly decreased pain and swelling within the first 24 hours after L3MS compared with the control group.Objetivo: Esta revisión aborda una pregunta de investigación clínica relacionada con la cirugía del tercer molar inferior (L3MS): ¿la combinación de ketamina preventiva en dosis bajas con anestesia local (KLA) reduce las complicaciones postoperatorias en comparación con la anestesia local (AL) sola? Material y Métodos: Se realizó una búsqueda bibliográfica sistemática para identificar artículos elegibles mediante búsquedas electrónicas en PubMed, Registro Cochrane Central de Ensayos Controlados, Biblioteca EBSCO, Web of Science y literatura gris hasta junio de 2019 sin restricciones de datos ni de idioma. Se analizaron todos los estudios clínicos controlados aleatorios (ECA) que compararon el uso de KLA con el uso de LA en L3MS con respecto a los resultados de dolor, hinchazón y trismo. La calidad de la evidencia se clasificó de acuerdo con la herramienta Cochrane para evaluar el riesgo de sesgo. Resultados: Se incluyeron en este estudio cinco ECA que abarcan 230 sitios de extracción (KLA = 115, LA = 115). La diferencia de medias estandarizada (DME) con el intervalo de confianza (IC) del 95% se utilizó para sintetizar los resultados. Los datos muestran que hubo diferencias significativas entre los dos grupos en el dolor posoperatorio (DME -1,464; IC del 95%: -1,683 a -0,949; p= 0,001) e hinchazón (DME -0,450; IC del 95%: -0,758 a -0,142 , p= 0,004, todas las pruebas de baja calidad). Sin embargo, no hubo diferencias significativas en el trismo (DME -0,754; IC: -1,487 a -0,022; p= 0,043, evidencia de muy baja calidad). Conclusión: La combinación de ketamina preventiva en dosis bajas con LA disminuyó significativamente el dolor y la hinchazón dentro de las primeras 24 horas después de la L3MS en comparación con el grupo de control

    Subciliary vs. transconjunctival approach for the management of orbital floor and periorbital fractures: A systematic review and meta-analysis

    This study compared complications between subciliary and transconjunctival approaches to the infraorbital rim/orbital floor, using systematic review and meta-analysis. A systematic review with meta-analysis was conducted according to PRISMA guidelines. An electronic search in PubMed, Embase, and Cochrane Library was performed. Randomized controlled and controlled (retrospective or prospective) clinical studies, with the aim of comparing subciliary to transconjunctival approaches in the management of infraorbital rim/orbital floor fractures, were included. Outcome variables were lower lid malposition including ectropion, entropion, scleral shows, canthal malpositions, and others complications. An odds ratio (OR) of outcome variables, using a Mantel–Haenszel (M−H) test with 95% confidence intervals (95% CIs), was calculated using Comprehensive Meta-analysis Software. A descriptive analysis of postoperative complications was also presented. The subciliary approach had a significantly higher incidence of ectropion and scleral show when compared with the subconjunctival approach (p < 0.001). The subconjunctival approach had a significantly higher incidence of entropion than the subciliary approach (p < 0.001). Both the subciliary and the transconjunctival approaches are associated with specific complications. Overall, the transconjunctival approach shows the lowest incidence of complications
