    Study Notes

    Local Anesthesia Techniques in Oral and Maxillofacial Surgery

    • The OMFS 311 course is directed by Dr. Nedal Abu Mostafa, an Assistant Professor of Oral and Maxillofacial Surgery.
    • Local anesthesia techniques in the maxilla include submucosal topical, supraperiosteal, sub-periosteal infiltration, intra-osseous, intra-septal, field block, intra-ligamentary, posterior superior alveolar, anterior and middle superior alveolar, greater palatine, and incisive canal.
    • Supra-periosteal injection in the buccal vestibule is the most commonly used technique in the maxilla, but it has disadvantages for treating multiple teeth.
    • The technique for supra-periosteal injection involves using a short needle inserted at the height of the mucobuccal fold above the apex of the tooth, with the syringe parallel to the long axis of the tooth and the bevel toward the bone.
    • Failure of anesthesia with supra-periosteal injection can occur if the injection is too far away from the apex or too far into the buccal soft tissue.
    • Palatal anesthesia can be achieved through sub-periosteal injection, which involves injecting under pressure into the firm palatal muco-periosteum.
    • Greater palatine injections should be avoided posterior to the second molar tooth to prevent nerve damage and intravascular injection.
    • Posterior superior alveolar nerve block is used for treatment of two or more maxillary molars when supra-periosteal injection is contraindicated, but it can cause hematoma formation due to trauma to the pterygoid venous plexus.
    • Anterior superior alveolar nerve block is used for treatment of two or more maxillary teeth and involves inserting the needle at the height of the mucobuccal fold directly over the maxillary first premolar.
    • Greater palatine nerve block is used when palatal anesthesia is required for more than two teeth and involves injecting slightly anterior to the greater palatine foramen.
    • Nasopalatine nerve block is used for anesthesia of the anterior part of the hard palate and its overlying soft tissues and involves injecting beneath the incisive papilla.
    • Maxillary nerve block can be achieved through a high-tuberosity or greater palatine canal approach.
