This study investigated the use of endonasal infiltrative anesthesia for the management of pain associated with nasal bone fracture reduction. Fifty-two patients with nasal bone fractures were distributed in 2 groups. In the first group, topical endonasal anesthesia and external transcutaneous infiltrative anesthesia were employed. In the second group, endonasal infiltrative anesthesia was also added. Visual analog scale pain scores related to the different steps of the procedure were registered. The addition of endonasal infiltrative anesthesia was associated with a significant decrease (p < .05) in pain during reduction maneuvers (6.71 vs. 4.83) and nasal packing (5.18 vs. 3.46). Addition of endonasal infiltrative anesthesia is an effective method of pain reduction during nasal bone fracture treatment.
