Craniofacial microsomia is a term used to describe a spectrum of abnormalities that primarily affect the development of the skull (cranium) and face before birth. Microsomia means abnormal smallness of body structures. Most people with craniofacial microsomia have differences in the size and shape of facial structures between the right and left sides of the face (facial asymmetry). Hemifacial Microsomia is a condition in which the lower half of one side of the face is underdeveloped and does not grow normally. It is sometimes also referred to as first and second brachial arch syndrome, oral-mandibular-auricular syndrome, lateral facial dysplasia, or otomandibular dysostosis.
Hemifacial microsomia is a congenital condition in which the tissues on one side of the face are underdeveloped. It primarily affects the ear, mouth and jaw areas, though it may also involve the eye, cheek, neck and other parts of the skull, as well as nerves and soft tissue. Hemifacial microsomia (HFM), also called craniofacial microsomia (CFM), is a birth defect that occurs when a part of the face appears small or underdeveloped. It primarily affects the: ear jaw eye Author: Amber Erickson Gabbey.
In children with craniofacial microsomia (CFM), part of the face is smaller than normal. Usually it affects the ears and jaw. It also can affect the eyes, cheeks and bones of the neck. Microsomia is pronounced my-kruh-SO-mee-uh. CFM is the second-most common birth defect affecting the face. The most. Hemifacial microsomia is a subset of craniofacial microsomia. It is a spectrum of undergrowth conditions or malformations related to the craniofacial skeleton. They occur in 1 in 3,000 to 25,000 live births, second only to the incidence of cleft lip and palate.5/5(16).
What Is the Cause of Hemifacial Microsomia Syndrome? The precise cause of Hemifacial Microsomia may be one of the several vascular problems that affect blood flow during pregnancy. Due to interrupted or faulty blood flow to the facial areas, the fetus begins to develop its face irregularly, with some areas growing at a slower pace. Hemifacial microsomia is also known as Goldenhar syndrome, brachial arch syndrome, facio-auriculo-vertebral syndrome (FAV), oculo-auriculo-vertebral spectrum (OAV), or lateral facial dysplasia. What are the different types of HFM? The deformity in hemifacial microsomia varies greatly in the degree of severity and in the area of the face involved.
