Research on Undersized Jaws and Ears
Seattle Children’s doctors and scientists are studying causes and effects of craniofacial microsomia (CFM) and microtia (very small or abnormally shaped ears).
Several of our researchers receive funding support from the National Institutes of Health (NIH).
FACIAL Research Network for Craniofacial Microsomia
To improve care for all children with CFM, Dr. Carrie Heike and her team work on standard ways to define and treat this condition. In the past, medical centers have defined cases differently and treated CFM in different ways.
Heike led efforts to establish a national network to share information about children with CFM. Sharing information about a large number of children with CFM could help us understand what causes the condition. This may improve treatments.
Heike worked with Dr. Daniela Luquetti, researchers at Seattle Children’s and collaborators across the country to start the network. It is called Facial Asymmetry Collaborative for Interdisciplinary Analysis and Learning (FACIAL).

How CFM Affects Children’s Development
Seattle Children’s researchers are studying CFM’s effect on how babies and toddlers develop. They also are exploring hearing in children with CFM who are between 1 year and 3½ years old.
Knowing if there is a link between CFM and children’s social and learning problems could lead to better treatment at an early age. Study leaders are Dr. Carrie Heike and Matthew Speltz.
Genetic and Environmental Factors in Microtia
Dr. Carrie Heike studies the DNA of people with microtia to learn about changes in genes that cause the condition. She works with researchers here and in South America, where microtia seems to be more common.
Researchers also are studying whether factors in the environment raise the risk for this condition.
Children may have microtia by itself. It also happens as part of conditions such as CFM or Treacher Collins syndrome.
