Perioperative trigeminocardiac reflex in patients undergoing surgical treatment of temporomandibular joint ankylosis: A study.

Purpose: The behavior of trigeminocardiac reflex (TCR) is limited to few case reports only in maxillofacial surgery, especially for temporomandibular joint (TMJ) ankylosis cases. The present study aims to find out the incidence of bradycardia due to TCR during intraoperative forceful mouth opening in TMJ ankylosis patients.

Materials And Methods: A prospective, unicentric observational study was conducted selecting those patients who were planned for osteoarthrectomy with interpositional gap arthroplasty under general anesthesia.
