Mandibular Nerve Block Anesthesia Puncture Needle

The lower margin of zygomatic arch and the midpoint of mandibular notch were used as puncture points for mandibular nerve block anesthesia. Local disinfection should be performed before puncture, and the injection process must be slow until it reaches the bone surface and stops.

The complications of mandibular nerve block should be paid attention to, the dosage of anesthetics should be strictly mastered and the operation should be carried out correctly. When injecting anesthetic, ensure that no blood is drawn back, and slowly withdraw the needle after injection.

Mandibular nerve block and anaesthesia block were marked by mandibular teeth, bicuspid teeth to medial incisor labial gums, periodontal membrane. The ipsilateral mandible and lower lip feel numb, no pain when stimulated.
