Anesthesia · single question

The Gow-Gates mandibular block anesthetizes which structures?

  1. Inferior alveolar and lingual nerves (essentially the entire V3)
  2. Only the inferior alveolar nerve
  3. Posterior superior alveolar nerve
  4. Mental and incisive nerves only
Show answer and explanation

Correct answer: A. Inferior alveolar and lingual nerves (essentially the entire V3)

  • A. Correct. Gow-Gates targets the neck of the condyle and anesthetizes nearly all V3 branches — inferior alveolar, lingual, buccal, mylohyoid and auriculotemporal.
  • B. A standard IAN block (not Gow-Gates) is more limited; Gow-Gates is broader.
  • C. The PSA is a maxillary branch, unrelated to the Gow-Gates mandibular technique.
  • D. Mental/incisive coverage is only part of the territory; Gow-Gates covers far more.
