A Bifid Mandibular Nerve as a Possible Cause of Anesthetic Deficiency in the Mandible

摘要

The failure to achieve complete mandibular anesthesia is a problem that occurs in as high as 20% of all cases. The explanations vary from faulty anesthetic solutions to faulty technique, to anatomic or physiologic variations. Accessory nerve innervation from the mylohyoid nerve or the contra-lateral mental nerve has also been suggested. Bifurcation of the mandibular nerve is rarely mentioned in the literature, but may be a cause for inadequate anesthesia in some small percentage of cases. (Author)
