For anesthesia during a procedure on the anterior 2/3 of the tongue, the best choice is:

  1. Inferior alveolar nerve block
  2. Glossopharyngeal nerve block
  3. Internal laryngeal nerve block
  4. Long buccal nerve block
Show answer and explanation

Correct answer: A. Inferior alveolar nerve block

The anterior 2/3 of the tongue receives general sensation from the lingual nerve (branch of CN V3). An inferior alveolar nerve block, when correctly administered, also anesthetizes the lingual nerve as it branches nearby, providing excellent anesthesia for the anterior tongue.
