  1. The Furlow double-opposing Z-plasty for cleft palate repair primarily achieves which functional goal?

    Answer: Lengthens the soft palate and reorients the levator muscle

    The Furlow palatoplasty lengthens the soft palate and repositions the levator veli palatini muscle into a more normal transverse sling orientation.

  2. Alveolar bone grafting for cleft lip and palate patients is optimally timed at which dental stage?

    Answer: Mixed dentition stage with canine root half-formed

    Secondary alveolar bone grafting is performed in the mixed dentition stage when the canine root is approximately half-formed, allowing the tooth to erupt through the graft.

  3. Treacher Collins syndrome (mandibulofacial dysostosis) results from mutations affecting which gene?

    Answer: TCOF1 (Treacle)

    Treacher Collins syndrome is caused by mutations in TCOF1, encoding the nucleolar phosphoprotein Treacle, which disrupts neural crest cell development.

  4. In the management of a child with a rapidly involuting congenital hemangioma (RICH), the expected natural history is:

    Answer: Complete involution before or shortly after birth within the first year

    RICHs are fully formed at birth and involute rapidly, typically completing regression within 12–14 months of life without treatment.

  5. Which craniosynostosis syndrome is associated with mitten-hand deformity (complex syndactyly of fingers 2–4)?

    Answer: Apert syndrome

    Apert syndrome is uniquely associated with complex, symmetric syndactyly of fingers 2–4 (mitten hand) and toes, distinguishing it from other craniosynostosis syndromes.

  6. Preoperative nasoalveolar molding (NAM) in cleft lip repair is designed to achieve which primary objective?

    Answer: Approximate cleft segments to reduce surgical tension at repair

    NAM remodels the nasal cartilage and approximates the alveolar segments preoperatively, reducing tissue tension at the time of definitive cleft lip repair.
