The O.M.E.N.S. Classification of Hemifacial Microsomia - A.
Hemifacial microsomia (HFM), also called craniofacial microsomia (CFM), is a birth defect that occurs when a part of the face appears small or underdeveloped.

All patients had nonsyndromic unilateral craniofacial microsomia (Pruzansky-Kaban types IIA, IIB, and III). Follow-up for all patients continued until the completion of growth.
Abstract Background: The authors examined hemifacial microsomia using three-dimensional computed tomography and the Kaban modification of the Pruzansky classification to determine its relationship with traditional evaluation and its reproducibility among evaluators. Methods: A retrospective review of all patients diagnosed with hemifacial microsomia was performed.
In our department, the treatment for craniofacial microsomia has been based on the Kaban's modified classification. In type I, the management we use is orthopedic treatment to stimulate maxillary and mandibular growth. In type IIa and IIb we use distraction osteogenesis of the mandible and practice orthopedic treatment management at the same time.
The purpose of this study was to analyze the statistical association between variable clinical phenotypes of the orbit, mandible, ear, nerve, soft tissue (OMENS) classification system in Oriental patients with hemifacial microsomia (HFM) and compare the data of Oriental children with data from other Western centers. One hundred consecutive patients with HFM referred to the Seoul National.
METHODS: A retrospective review of all patients diagnosed with hemifacial microsomia was performed. Three-dimensional computed tomographic scans were reviewed by expert evaluators and rated according to evaluators' understanding of the Kaban modification of the Pruzansky classification.
