Introduction: Securing a difficult airway during maxillofacial surgeries is a great challenge for anesthetists, and the flexible fiber-optic bronchoscope is the gold standard while managing such cases. While passing the flexible bronchoscope by the nasal route, the success rate is higher as compared with oral approach as the nasopharynx is in line with the larynx and prevents acute angulation in the oropharynx. Materials and Methods: A randomized control trial was planned in 73 patients out of whom sixty patients gave consent for the procedure. The patients we randomly divided into two groups (n = 30) with application of 4% nebulized lignocaine in one group and the use of 2% nebulized lignocaine in the other group, and the patient's comfort was noted using five-point Puchner scale. Results: The mean value of patient comfort Puchner scale of Group A was 1.30 ± 0.08 and of Group B was 2.23 ± 0.12. The mean value of Puchner scale of Group B was significantly higher (41.8%) as compared to Group A (t = 6.208; df = 51; P < 0.0001). The secondary outcome measures were optimal intubating conditions and hemodynamic changes during awake fiber-optic nasotracheal intubation. The procedural time of two groups when compared showed that the mean procedural time of Group A was shorter (29.67 ± 5.40 min) than the time consumed in Group B (34.93 ± 5.52 min). Conclusion: Four percent nebulized lidocaine provided adequate airway anesthesia and optimal intubating conditions along with stable hemodynamics for awake fiber-optic intubation as compared to 2% nebulized lidocaine.
