The clinical presentation of<unk>  is quite variable. The severity may depend on the extent of the area with an insufficient blood supply in utero, and the gestational age of the fetus at which this occurs. In some people, the only physical manifestation may be a small and underdeveloped external ear. In more severe cases, multiple parts of the face may be affected. Some people with<unk>  may have sensorineural hearing loss and decreased visual acuity or even blindness. It can be thought of as a particularly severe form of<unk> , in which extracranial anomalies are present to some extent. Some of the internal organs (especially the heart, kidneys, and lungs) may be underdeveloped, or in some cases even absent altogether. The affected organs are typically on the same side as the affected facial features, but bilateral involvement occurs in approximately 10% of cases. Deformities of the vertebral column such as scoliosis may also be observed. While there is no universally accepted grading scale, the OMENS scale (standing for Orbital, Mandible, Ear, Nerves and Soft tissue) was developed to help describe the heterogeneous phenotype that makes up this sequence or syndrome. Intellectual disability is not typically seen in people with<unk> .<unk>  sometimes results in temporomandibular joint disorders.
