“…Gillespie [24] reported bradycardia during elevation of zygomatic fractures again in 1988. Reaume and MacNicol [25] also reported same phenomena during Lefort I osteotomy in the same year. Later Shelly and Church [22] reported bradycardia during facial surgery and suggested the term ''trigeminocardiac reflex''.…”

Trigemino-cardiac reflex is occurrence of hypotension and bradycardia upon surgical manipulation of areas supplied by the trigeminal nerve, and has been reported during craniofacial maxillofacial and ocular surgeries. Communication between the anaesthetic and surgical team is essential, and cessation of the precipitating stimulus is the first and most important therapeutic step. We report a case of immediate, reproducible, and reflexive response of Bradycardia and dysrhythmia upon manipulation of orbital fracture during orbital floor reconstruction in a 65-year-old man. Upon recognition of the reproducible relationship between falcine stimulation and increased vagal tone, the patient was given atropine in an effort to block cholinergic hyperactivity. After atropine administration, no further dysrhythmias occurred and surgery was carried uneventfully.

“…If the required amount of movement is still not obtained, inferior resection of the pterygoid process 9 may be considered to facilitate maxillary setback, as it will increase somewhat the range of posterior movement. However, a variety of complications can occur, such as excessive bleeding 10,11 and injuries to the cranial nerve 12,13 and carotid artery. 14,15 Until now, safe and reliable surgical procedures for moving the maxilla posteriorly have not been available.…”

This report describes an orthognathic surgical case employing horseshoe Le Fort I osteotomy (HLFO) combined with mid-alveolar osteotomy and bilateral sagittal split ramus osteotomy (BSSRO) for a patient with severe unilateral scissor bite and bimaxillary protrusion. A female patient (aged 26 years, 2 months) presented with a chief complaint of dysmasesis caused by scissor bite on the right side. The clinical examination revealed difficulty in lip closure and a convex profile. Overerupted right maxillary premolars and molars and lingual tipping of the right mandibular premolars and molars were indicated before treatment. After 3 months of presurgical orthodontic treatment, two-jaw surgery involving a combination of HLFO with mid-alveolar osteotomy and BSSRO was performed. A good interdigitation in the right side was established by superiorposterior-medial movement of the dento-alveolar segment of the maxilla. Next, both the maxilla and mandible were moved superiorly and posteriorly to correct the improper lip protrusion, thereby improving the patient's profile. Our results suggest that this new orthognathic surgery techniqueachieved by combining HLFO with mid-alveolar osteotomy and BSSRO-is effective for adult patients exhibiting severe unilateral scissor bite and bimaxillary protrusion.

Trigemino cardiac reflex (TCR) which was originally called as OCCULOCARDIAC REFLEX is a physiological response due to the pressure effect on the largest cranial nerve, the trigeminal nerve. Oral and maxillofacial procedures can induce the development of this reflex. TCR is a triad of bradycardia , bradypnea and gastric motility changes due to the efferent activation of the vagal nerve in response to the pressure distribution in Trigeminal nerve. TCR may be generated as a result of procedures or conditions that increase intraocular pressure, strabismus surgery, nasal packing after rhinoplasty, the reduction of zygoma and zygomatic arch fractures, elevation of bone flap or osteotomies, reflection of a palatal flap for removal of a mesiodens, during Le Fort I downfractures, sagittal split ramus retraction, midface disimpaction, cutting maxillary tuberosity, and temporomandibular joint arthroscopy. The purpose of this paper is to discuss the pathophysiology and to review the main risk factors , treatment, prevention and management with emphasis on the role of maxillofacial surgeons and attending anesthetist. Maxillofacial surgeons should be familiar with presentations, preventive measures for the effective management of this complication.
