Question 1

What is the recommended timing for primary cleft palate repair to optimize speech development?

Accepted Answer

Between 9 and 18 months of age

Answer

Cleft palate repair between 9 and 18 months allows velopharyngeal function to develop before the critical period for speech acquisition.

Question 2

Pierre Robin sequence is defined by which triad of findings?

Accepted Answer

Micrognathia, glossoptosis, and cleft palate

Answer

Pierre Robin sequence classically presents with micrognathia (small jaw), glossoptosis (tongue falling back), and a U-shaped cleft palate causing airway obstruction.

Question 3

Mandibular distraction osteogenesis for severe micrognathia in neonates activates bone regeneration in which phase?

Accepted Answer

Distraction phase during active lengthening

Answer

New bone forms in the distraction gap during the active distraction phase as the corticotomy segments are slowly pulled apart.

Question 4

In cranial vault remodeling for unicoronal craniosynostosis, which deformity of the orbit must be specifically corrected?

Accepted Answer

Harlequin eye deformity with elevated ipsilateral orbital roof

Answer

Unicoronal synostosis produces the characteristic harlequin eye deformity—elevation and rotation of the ipsilateral orbital roof—that requires correction during fronto-orbital advancement.

Question 5

Which vascular anomaly classification distinguishes hemangiomas from vascular malformations?

Accepted Answer

Mulliken and Glowacki classification

Answer

Mulliken and Glowacki's 1982 biological classification distinguishes hemangiomas (proliferating endothelial cells) from vascular malformations (structural errors with normal cell turnover).
