All of the following are features associated with cleft palate EXCEPT one. Which is the EXCEPTION?

  1. Ectopic eruption of anterior teeth
  2. Mandibular micrognathia
  3. Feeding difficulties in infants
  4. Missing or malformed teeth
Show answer and explanation

Correct answer: B. Mandibular micrognathia

  • A. Ectopic eruption of teeth adjacent to the cleft is common, particularly of the maxillary incisors and canines.
  • B. CORRECT. Mandibular micrognathia (small mandible) is NOT a typical feature of isolated cleft palate. Mandibular micrognathia is associated with Pierre Robin sequence (retrognathic mandible + posterior cleft palate + glossoptosis) — but in isolated cleft palate without Pierre Robin, the mandible is normal.
  • C. Feeding difficulties are among the earliest and most significant complications of cleft palate, as the infant cannot generate adequate negative pressure for suckling.
  • D. Missing teeth (hypodontia) and malformed teeth frequently occur in the cleft area, particularly lateral incisors near the cleft site.
