Cleft Palate Flashcards
(12 cards)
At what embryologic week does the primary palate form, and what happens if fusion fails?
At approximately 6 weeks. Failure results in clefts of the lips and/or maxilla.
When does the secondary palate form, and what causes unilateral/bilateral clefts?
At 8 weeks. Unilateral cleft: one palatal shelf fails to fuse. Bilateral cleft: both shelves fail to fuse with the septum.
What are three examples of cleft lip classifications?
- Minor left incomplete unilateral cleft lip.
- Left incomplete unilateral cleft lip and palate.
- Wide left complete unilateral cleft lip and palate.
Is cleft lip/palate a single-gene disease? What is its etiology?
No. It’s multifactorial, involving chemical exposures, radiation, maternal hypoxia, drugs, nutrition, or genetics.
Why do infants with cleft palate struggle with feeding?
They cannot form a seal between tongue and palate to create negative pressure for sucking.
When is cleft lip repair typically performed?
After 10 weeks of age to allow for medical evaluation.
What is the timing for cleft palate repair?
Between 9–18 months of age.
When is maxillary/alveolar bone grafting performed?
At 6–9 years, based on dental development.
What is the recommended age for cleft orthognathic surgery?
14–16 years in girls, 16–18 years in boys.
When is cleft rhinoplasty ideally performed?
After age 5, preferably at skeletal maturity (after orthognathic surgery if possible).
What is the controversy regarding breastfeeding infants with cleft palate?
Some practitioners encourage it, while others oppose it due to feeding difficulties.
What is the key consideration in cleft treatment planning?
Balancing functional needs, aesthetics, and ongoing growth.
