title: Decreased postoperative pain after reduction of fractured nasal bones using a nerve block of the anterior ethmoidal nerve.
abstract: There is consensus that all patients should experience minimal pain following reduction of a fractured nasal bone. The issue requiring further study is what technique will provide patients with the greatest pain relief following the reduction of nasal fractures. This study investigated the use of an anterior ethmoidal nerve block as preemptive analgesia for the management of postoperative pain associated with reduction of nasal bone fractures. The medical documents of 85 patients were reviewed for a retrospective case-controlled comparative study. Patients in the nerve block group (n=45) were injected with 2% lidocaine containing epinephrine into the anterior ethmoidal nerve and dorsal periosteum, and those in the control group (n=40) were not. The rate of patients requiring postoperative injectable analgesics was compared between the two groups. The rate of patients who received a postoperative analgesic injection was significantly lower in the nerve block group than in the control group (P=0.034). The use of an anterior ethmoidal nerve block and dorsal periosteal injection of anaesthetic solution during reduction of fractured nasal bones under general anaesthesia resulted in the effective reduction of postoperative pain. Thus, this is regarded as a good method for enhancing patient quality of care and compliance in the reduction of fractured nasal bones.
