Background: Many oral airways are used for aiding fiberoptic bronchoscope (FOB)-guided endotracheal intubation. This study was done to evaluate modified William's airway, modified Guedel's airway, and LMA MADgic airway as conduits for FOB-guided endotracheal intubation. Methods: Sixty patients presented for elective surgery under general anesthesia were randomly allocated into three groups: Modified Guedel's airway group (G G ), modified Williams airway group (G W ), and LMA MADgic airway group (G M ). The three study groups were compared with regard to time of insertion of the airway, time of intubation, ease of airway insertion, number of intubation attempts, Laryngeal View Grade (LVG), and the incidence of complications. Results: G w had shorter time of airway insertion, shorter time of intubation, lower number of intubation attempts, and better laryngeal view compared to G G and G M . The anesthesiologist was more comfortable in G w compared to the other two groups.The incidence of complications (sore throat, and blood-stained airway) was comparable between the three groups. Conclusion: Modified Williams airway provided shorter time of endotracheal tube intubation, and lower number of intubation attempts in comparison to modified Guedel's airway and LMA MADgic airway when used as conduit for FOB-guided endotracheal intubation. This randomized controlled study was conducted in Cairo University Hospital. Research Ethics Committee approved the study (N-40-2016).
