When giving the IA injection, where is the solution deposited?

• A. Above the mandibular foramen
• B. Below the mandibular canal
• C. Inside the mandibular foramen
• D. In the pterygomandibular space

Answer: (A)

The goal of the inferior alveolar nerve block is to anesthetize the inferior alveolar nerve as it enters the mandibular canal. To achieve this, the anesthetic is deposited in the pterygomandibular space, just medial to the ramus and slightly above the mandibular foramen. Depositing the solution just above the foramen ensures it surrounds the nerve as it enters the canal, providing effective anesthesia to the intended teeth and associated tissues. Depositing below the canal or inside the foramen would be less likely to reach the nerve fibers effectively.
