This study aimed to test the non-inferiority of topical 11000 epinephrine compared to topical 110 000 with regard to intraoperative hemodynamic stability, and to determine whether it produced superior visibility conditions. A single-blinded, prospective, cross-over non-inferiority trial was performed. Topical 11000 or topical 110 000 was placed in 1 nasal passage. Hemodynamic parameters (heart rate, systolic and diastolic blood pressures, and mean arterial pressure) were measured prior to insertion then every minute for 10 min
