Effectiveness of protocolized management for patients sustaining maxillofacial fracture with massive oronasal bleeding: a single-center experience

Abstract

Abstract Background Maxillofacial fractures can lead to massive oronasal bleeding; however, surgical hemostasis and packing procedures can be challenging owing to complex facial anatomy. Only a few studies investigated maxillofacial fractures with massive oronasal hemorrhage. However, thus far, no studies have reported a protocolized management approach for maxillofacial trauma from a single center. This study aimed to evaluate the effectiveness of protocolized management for maxillofacial fractures with oronasal bleeding. Methods Patients were identified from the National Cheng University Hospital trauma registry from 2010 to 2020. We included patients with a face Abbreviated Injury Scale (AIS) score of > 3 and active oronasal bleeding. Patients’ characteristics were compared between the angiography and non-angiography groups and between survivors and nonsurvivors. Results Forty-nine patients were included. Among them, 34 (69%) underwent angiography, of whom 21 received arterial embolization. Forty-seven patients (96%) successfully achieved hemostasis by adhering to the treatment protocol at our institution. Compared with the non-angiography group, the angiography group had significantly more patients requiring oral intubation (97% vs. 53%, P 3 (65% vs. 13%, P = 0.001), higher Injury Severity Score (ISS; 43 [33–50] vs. 22 [18–27], P 3 (92% vs. 33%; P < 0.001), skull base fracture (100% vs. 64%; P = 0.011), GCS score < 9 (100% vs. 50%; P = 0.003), higher ISS (50 [43–57] vs. 29 [19–48]; P < 0.001), and more units of PRBC transfused within 24 h (18 [13–22] vs. 6 [2–12]; P = 0.001) than the survivor group. More patients underwent angiography in the nonsurvivor group than in the survivor group (92% vs. 61%; P = 0.043). Among embolized vessels, the internal maxillary artery (65%) was the most common bleeding site. Hypoxic encephalopathy accounted for 92% of deaths. Conclusions Protocol-guided management effectively optimizes outcomes in patients with maxillofacial bleeding.
