Trigeminocardiac reflex (TCR) is a cascade of physiological response secondary to the stimulation of any of the sensory divisions of the trigeminal nerve, which is the largest cranial nerve and provides sensory supply to the face, scalp, mucosa of the nose, and mouth. This response usually presents as a triad including bradycardia, apnea, and gastric motility changes. On the another side, transient loss of consciousness or vasovagal syncope, a well-known phenomenon in dentomaxillofacial surgery with its pathophysiology fully elucidated, is thought to be mediated by TCR and sometimes termed as dentocardiac reflex. Thus, it is imperative to know about TCR and its association with routine dental and maxillofacial surgery procedures. It can potentially happen during any minor or major oral surgical procedures ranging from simple third molar extractions, soft tissue surgeries, root canal treatments, or management of maxillofacial fractures. This paper presents two case reports demonstrating TCR which presented during maxillary third molar extraction and author(s) own experience in managing the same.
