Anesthesia · single question

During a Gow-Gates mandibular nerve block, which nerves are primarily anesthetized?

  1. Inferior alveolar and lingual nerves (and more)
  2. Mental nerve and buccal nerve only
  3. Lingual and long buccal nerves only
  4. Inferior alveolar nerve only
Show answer and explanation

Correct answer: A. Inferior alveolar and lingual nerves (and more)

The Gow-Gates technique anesthetizes V3 at the condylar neck, providing broad coverage: inferior alveolar, lingual, mental, buccal, auriculotemporal, and mylohyoid nerves. Much broader than the conventional Halsted block.
  • A. CORRECT. Gow-Gates block = IAN + lingual + mental + buccal + auriculotemporal + mylohyoid nerves. Single injection at condylar neck.
  • B. Mental and buccal nerve only is far too limited to describe Gow-Gates coverage.
  • C. Lingual and long buccal only would be insufficient for dental procedures.
  • D. Anesthetizing only the IAN is what the conventional Halsted block achieves — not Gow-Gates.
