Asystole induced by trigeminocardiac reflex during zygomatic fracture repositioning: A rare case report.

The trigeminocardiac reflex (TCR) in maxillofacial surgical procedures can occasionally lead to sudden bradycardia in response to the manipulation of maxillofacial bony structures. However, asystole induced by TCR during maxillofacial surgery has rarely been reported. Here, we report an extremely rare case of ventricular asystole induced by the TCR in a 56-year-old female patient, which was caused by zygomatic fracture repositioning during the surgical repair of a zygomaticomaxillary complex fracture. Chest compressions that were performed immediately by the oral-maxillofacial surgeons was successful, and an electrocardiogram confirmed the patient's return to sinus rhythm. The patient's postoperative clinical course was unremarkable. [ABSTRACT FROM AUTHOR]
