# **Long Buccal Nerve Block Technique** ## **Anatomical Landmarks and Pathway** The long buccal nerve travels from the medial aspect upward, crossing over and descending along the buccal region. Key landmarks to identify prior to injection include: - **Internal Oblique Ridge:** Located on the medial (inner) aspect. - **External Oblique Ridge:** Located on the lateral (outer) aspect. - **Coronoid Notch:** Serves as the primary depression along the anterior border of the ramus. By palpating the area with a finger, you can locate where the internal and external ridges run parallel to each other. The target zone lies directly between these two ridges. ## **Step-by-Step Injection Procedure** ### **Preparation and Tissue Management** - Palpate the coronoid notch. - **Puff the Tissue:** The soft tissue in this region is often extremely thin, sometimes providing less than a millimeter of depth. Retracting and bunching or "puffing" the tissue creates adequate thickness for the injection site. ### **Needle Insertion and Delivery** 1. **Orientation:** Align the syringe parallel to the occlusal plane. 2. **Height of Insertion:** Aim approximately 4 millimeters above the occlusal plane. 3. **Penetration:** Direct the needle straight back into the prepared, elevated tissue. Bone contact is typically made almost immediately due to the shallow depth. 4. **Aspiration:** Pause and aspirate to confirm negative placement. 5. **Deposition:** Administer approximately half of a carpule. > [!tip] Target Window Flexibility > The long buccal nerve block offers a broad margin of error. The solution may be delivered slightly more rapidly than deeper blocks, and effective anesthesia can be achieved across multiple adjacent points throughout this anatomical zone. # **Long Buccal Nerve Block Technique** ## **Anatomical Landmarks and Pathway** The long buccal nerve travels from the medial aspect upward, crossing over and descending along the buccal region.

Long Buccal Nerve Block Technique A close-up view of a dental procedure where a gloved hand uses a retractor to expose the buccal mucosa and molars, likely in preparation for a long buccal nerve block injection. A close-up view of a gloved finger palpating the upper gum ridge inside a patient's mouth to locate anatomical landmarks for an injection. The clip demonstrates a clinical technique where the operator palpates the coronoid notch and manually retracts or 'puffs' thin soft tissue to create sufficient depth for an injection. The clip demonstrates the clinical steps for a dental injection, including aiming the needle 4mm above the occlusal plane, penetrating the tissue until bone contact is made, aspirating, and depositing the anesthetic. The clip demonstrates the clinical steps of pausing to aspirate for negative placement followed by injecting approximately half a carpule. It outlines the specific actions for aspiration and deposition within a medical technique.
