Pierre Robin sequence characteristics include all of the following EXCEPT:

  1. Cleft palate
  2. Glossoptosis (posterior displacement of tongue)
  3. Micrognathia (small mandible)
  4. Bifid (split) tongue
Show answer and explanation

Correct answer: D. Bifid (split) tongue

  • A. Incorrect — cleft palate IS a feature. The U-shaped (not V-shaped) cleft palate is a classic associated finding.
  • B. Incorrect — glossoptosis IS a feature. The small mandible causes the tongue to fall backward (glossoptosis), potentially obstructing the airway.
  • C. Incorrect — micrognathia IS a feature. Small mandible (micrognathia) is the primary defect in Pierre Robin sequence.
  • D. Correct — BIFID TONGUE is NOT a feature of Pierre Robin sequence. Bifid tongue (cleft tongue) is associated with other syndromes. Pierre Robin features are: micrognathia, glossoptosis, cleft palate, and airway obstruction.
