Anesthesia · single question

The Gow-Gates mandibular block is described as the best technique to 'block more nerves.' This block targets which landmark?

  1. The neck of the mandibular condyle
  2. The internal oblique ridge
  3. The lingula of the mandible
  4. The pterygomandibular raphe
Show answer and explanation

Correct answer: A. The neck of the mandibular condyle

  • A. Correct. The Gow-Gates block deposits anesthetic high up near the neck (subcondylar area) of the mandibular condyle. At this location, nearly all branches of the mandibular nerve (V3) can be anesthetized with a single injection.
  • B. The internal oblique ridge is a landmark for the standard IAN block.
  • C. The lingula (mandibular foramen) is the target of the standard IAN block, not Gow-Gates.
  • D. The pterygomandibular raphe is a visual landmark for all mandibular blocks but is not the specific Gow-Gates target.
