Transcript of "palate"

  1. 1. Cleft lip and palate Normal development of the face and palate <ul><li>Primary palate </li></ul><ul><li>upper lip and alveolar ridge </li></ul><ul><li>develop between 4 th and 8 th week of gestation </li></ul><ul><li>Secondary palate </li></ul><ul><li>hard and soft palates </li></ul><ul><li>develop between 8 th and 12 th week of gestation </li></ul><ul><li>Development can be interrupted by abnormal genetic conditions or environmental agents (teratogens) </li></ul>
  2. 2. Cleft lip and palate Classification systems <ul><li>Numerous classification systems: </li></ul><ul><li>Veau </li></ul><ul><li>American Cleft Palate-Craniofacial Assn (ACPA) </li></ul><ul><li>Kernahan and Stark </li></ul><ul><li>Veau’s system: </li></ul><ul><li>I Cleft of soft palate only </li></ul><ul><li>II Cleft of hard and soft palate to incisive foramen </li></ul><ul><li>III Complete unilateral cleft of soft and hard palate and lip and alveolar ridge on one side </li></ul><ul><li>IV Complete bilateral cleft of soft and hard palate and lip and alveolar ridge on both sides </li></ul>
  3. 3. Causes of cleft lip and palate <ul><li>Genetic disorders </li></ul><ul><li>Chromosomal abnormalities </li></ul><ul><li>Environmental factors (teratogenic agents) </li></ul><ul><li>Mechanical factors </li></ul>
  4. 4. Genetic factors <ul><li>Syndrome vs. sequence </li></ul><ul><li>Pierre Robin sequence </li></ul><ul><ul><li>Small mandible (micrognathia) causes failure of tongue to descend </li></ul></ul><ul><ul><li>Failure of the tongue to descend causes cleft </li></ul></ul><ul><ul><li>Heart problems, conductive hearing loss, developmental deficits </li></ul></ul><ul><ul><li>about 40% of infants with Pierre Robin have Stickler Syndrome and about 15% have Velocardiofacial Syndrome </li></ul></ul><ul><li>Treacher Collins syndrome </li></ul><ul><ul><li>Under-developed cheekbones with scalp hair </li></ul></ul><ul><ul><li>Malformed ears </li></ul></ul><ul><ul><li>Conductive hearing loss </li></ul></ul><ul><ul><li>Normal cognitive functioning </li></ul></ul>
  5. 5. Chromosomal abnormalities <ul><li>Trisomy 13 </li></ul><ul><ul><li>Rare chromosomal abnormality </li></ul></ul><ul><ul><li>Multiple congenital malformations </li></ul></ul><ul><ul><li>Mean life expectancy is 130 days </li></ul></ul>
  6. 6. Environmental factors <ul><li>Recognized teratogenic agents </li></ul><ul><ul><li>Drugs </li></ul></ul><ul><ul><li>Aspirin overdose </li></ul></ul><ul><ul><li>Acne medications </li></ul></ul><ul><ul><li>Alcohol overdose </li></ul></ul>
  7. 7. Mechanical factors <ul><li>Intrauterine crowding (tumors, multiple births, placenta abnormalities) </li></ul>
  8. 8. Incidence of cleft lip and palate <ul><li>1:750 live births </li></ul><ul><li>Clefts of lip only more frequent, more severe in males </li></ul><ul><li>Clefts of palate only more frequent in females </li></ul><ul><li>Native Americans have highest prevalence </li></ul><ul><li>African Americans have lowest prevalence </li></ul>
  9. 9. Management of clefts <ul><li>Surgical </li></ul><ul><ul><li>Primary </li></ul></ul><ul><ul><li>Secondary </li></ul></ul><ul><li>Dental </li></ul><ul><li>Audiological </li></ul><ul><li>Speech and Language </li></ul>
