%X <B>UNASSIGNED: </B>Trigeminal schwannoma (TS) is a very rare tumour in the head-and-neck region and the occurrence of intraoperative trigeminocardiac reflex (TCR), during surgery, should not be underestimated. The physiological function of this rare brainstem reflex is yet to be fully established.<BR><B>UNASSIGNED: </B>TCR occurs in a variety of surgeries, such as neurosurgical, maxillofacial, dental and skull base surgeries with bradycardia as the presenting sign.<BR><B>UNASSIGNED: </B>This is a clinical profile of two patients who presented with schwannoma of the trigeminal nerve.<BR><B>UNASSIGNED: </B>Intraoperatively, during dissection of tumour, both patients had bradycardia with hypotension.<BR><B>UNASSIGNED: </B>The first patient had a spontaneous recovery but the other required intervention with vasopressors.<BR><B>UNASSIGNED: </B>One must be aware of the rare occurrence of TCR mainly while operating on a rare occurring TS. Ceaseless intraoperative monitoring and being prepared with adequate measures while manipulating close to the nerve will prevent serious complications.
