Editor's Notes

  • #7 August 04
  • #34 ROSTRAL MANDIBULAR (MENTAL) REGIONAL BLOCK The rostral mandibular block infiltrates the rostral extent of the inferior alveolar nerve just before it exits the middle mental foramen. (Figures 6 and 7) The structures anesthetized include the incisors, the canine and the first three premolars. The adjacent bone and soft tissue are also affected. The middle mental foramen is located about 1/3 of the distance from the ventral border to the dorsal border of the mandible at the level of the mesial root of the second premolar. The landmark for infiltration is the mandibular labial frenulum. The frenulum is retracted ventrally. The needle is inserted at the rostral aspect of the frenulum and advanced along the mandibular bone to just enter the canal. If bone is encountered the needle should be backed out and redirected until the needle passes freely into the foramen. Placement can be confirmed by moving the syringe laterally to encounter the lateral aspect of the canal. The patient’s jaw, rather than the alveolar mucosa, will move slightly if the needle is within the canal. The mental nerve block gets the mandibular bone, teeth and soft tissue from the second premolar to the midline. The mandibular labial frenulum is retracted ventrally. The needle is directed into the mesial aspect of the frenulum and advanced against the bone distally to enter the middle mental foramen at the level of the distal frenulum.
