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