What causes Hypernasality?
Hypernasality is due to an abnormal opening between the nose and the mouth during speech. This is usually due to a form of velopharyngeal dysfunction (velopharyngeal insufficiency or velopharyngeal incompetence). Common causes include a history of cleft palate or submucous cleft palate.
What is the meaning of DiGeorge syndrome?
DiGeorge Syndrome (DGS) is a primary immunodeficiency, often but not always, characterized by cellular (T-cell) deficiency, characteristic facies, congenital heart disease and hypocalcemia. DGS is caused by abnormal formation of certain tissues during fetal development.
What is 22g?
DiGeorge syndrome, more accurately known by a broader term — 22q11. 2 deletion syndrome — is a disorder caused when a small part of chromosome 22 is missing. This deletion results in the poor development of several body systems.
How does Hypernasality work in speech therapy?
Speech Therapy for Children with Hypernasality
- Stimulability probe: Try to get the child to imitate oral resonance.
- Altering Tongue Position: Try for a lower, posterior tongue placement.
- Open Mouth: Have the child speak with his mouth more open.
- Change Volume: Try different volumes to see which has less nasality.
What causes DiGeorge?
DiGeorge syndrome is caused by a problem with a person’s genes, called 22q11 deletion. It is not usually passed on to a child by their parents, but it is in a few cases. It’s often diagnosed soon after birth with a blood test to check for the genetic fault.
What does DiGeorge syndrome affect?
DiGeorge syndrome is a chromosomal disorder that typically affects the 22nd chromosome. Several body systems develop poorly, and there may be medical problems, ranging from a heart defect to behavioral problems and a cleft palate. The condition is also known as 22q11.
What is the difference between Hypernasality and Hyponasality?
Hypernasality—occurs when there is sound energy in the nasal cavity during production of voiced, oral sounds. Hyponasality—occurs when there is not enough nasal resonance on nasal sounds due to a blockage in the nasopharynx or nasal cavity.
How do you evaluate hypernasality?
Feel sides of nose for vibration that might accompany perceived hypernasality. Alternately pinch and then release the nose (sometimes referred to as the cul-de-sac test or nasal occlusion) while individual produces a speech segment—a change in resonance indicates hypernasality.
What is DiGeorge syndrome?
DiGeorge syndrome is a genetic disorder that can affect many parts of the body. These problems, usually present at a baby’s birth or in early childhood, include heart defects, an impaired immune system and developmental delays.
What does DiGeorge mean?
DiGeorge syndrome is a genetic disorder that appears at birth or in early childhood. The syndrome may cause heart defects, somewhat different facial features and developmental delays. DiGeorge syndrome’s effects can range from minor to severe. What is DiGeorge syndrome?

What are the complications of DiGeorge syndrome in infants?
Infants with complete DiGeorge syndrome have additional symptoms including congenital heart defects and/or hypoparathyroidism. These complications can be significant. Congenital health defects are problems with the structure of the heart. This include the walls, valves, and arteries and veins of the heart.
