Children with congenital microtia may have a "big and small face" phenomenon while their ears are abnormally developed. Many parents wonder if this is caused by microtia.
However, actually,Ear dysplasia and facial dysplasia are not causal but rather different manifestations of the same condition.
So, why do big and small faces appear?
The size of the face, also known as the first.
1. Arch syndrome is a common congenital craniofacial malformation, second only to cleft lip and palate.
During development, soft tissues such as the mandible, maxilla, ears, facial muscles, and nerves all develop from structures known as the first and second branchial arches. When these structures are underdeveloped,It can lead to the appearance of large and small faces.
Among them,Skeletal dysplasia of the face is the main cause of facial deformitiesMandibular dysplasia is the most common and severe. This can lead to dysplasia or absence of the ascending branch of the mandible, as well as dysplasia of the body in all directions, and even significant dysplasia or absence of the joint in individual patients.
The deformed mandible will affect the normal downward growth of the maxilla, and affect the temporal bone, zygomatic bone, sphenoid bone, and even the temporomandibular joint, resulting in dysplasia of the upper and lower jaws and zygomatic bones, obvious asymmetry of bilateral facial facial development, hypoplasia of facial expression muscles, masticatory muscles and subcutaneous tissues, facial nerve paralysis, etc., resulting in secondary midfacial deformity.
Classification of hemifacial shortness deformity.
Therefore, whether a microtia patient has a large or small face is actually determined at birth.
In some children, the size of the face may become more pronounced as they grow and develop, but by puberty, they will improve as their muscles become fuller. Therefore, parents do not need to worry too much about this problem for their children.
