Do you know this syndrome? Goldenhar syndrome is a sporadic or inherited genetic syndrome characterized by limbal dermoids, preauricular skin tags and mandibular hypoplasia. Vertebral abnormalities may occur.

It consists of abnormalities involving the first and second branchial arches. The etiology of the syndrome is heterogeneous.

Translation of “faríngeos” in English

Diagnosis should be based principally on farungeos aspects, which should be associated with the patient’s systemic conditions and radiologic findings. Treatment depends on the patient’s age and systemic manifestations, with a multidisciplinary approach often being required.

Anormalidades vertebrais podem ocorrer. A nine-year-old girl, the daughter of a healthy and non-consanguineous couple, was referred with delayed neuropsychomotor development.

Her parents reported no abnormalities and no drug use during pregnancy. Clinical examination revealed low stature and facial arcps with the right hemiface smaller than arccos left one, the maxillary arch and right mandibular arch smaller than the left, right microtia with atresia of the ear canal and a systolic heart murmur grade 1 Figures A depressed scar was also found on the patient’s nose at the site of a previous apocrine hidrocystoma.

The patient had a normal karyotype 46 XX. Conventional lumbar spine radiography revealed an incomplete fusion of the posterior elements of S1.

Computed tomography of temporal bones showed agenesis of the right external auditory canal and absence of pneumatization faringsos the ipsilateral mastoid air cells, mild hypoplasia of the right ossicular chain, with deformity of the middle ear. Computed fsringeos of the paranasal sinuses revealed an asymmetry of the jaw and zygomatic bone on the right side. Echocardiogram findings indicated a discrete thickening of the aortic valve with slight regurgitation.

Goldenhar syndrome oculo-auriculo-vertebral syndrome is a rare congenital abnormality that involves the first and second branchial arches. Its etiology is unknown; however, there are some theories regarding the role played by exposure to viruses or the ingestion of certain drugs such as thalidomide, retinoic acid, tamoxifen and cocaine during pregnancy.

It may also be related arcox abnormal vascular supply to the first and second arch affecting the formation of the vertebral and branchial systems. Most cases of Goldenhar syndrome are sporadic; however, familial cases have been reported with autosomal dominant inheritance and variable expressivity. Cases with consanguinity between parents have also been reported, suggesting autosomal recessive inheritance.

The classic triad associated with the syndrome includes the presence of limbal dermoids, preauricular skin tags and pretragal fistulas. Limbal dermoids, which consist of benign fibrous tumors at the edge of the cornea, are a typical ocular abnormality in Goldenhar syndrome, and may be unilateral or bilateral. Auricular abnormalities include mild ear malformations, preauricular skin tags, atresia of the external auditory canal, and anomalies in the size and shape of the external auricle.

Vertebral skeletal anomalies include occipitalization of the atlas, spina bifida and kyphosis. Cardiac alterations consist of isolated ventricular septal defects or atrial septal defects, pulmonary stenosis and tetralogy of Fallot.


With respect to dental and facial abnormalities, facial asymmetry or hemifacial microsomia are always present in patients with this syndrome. Diagnosis of Goldenhar syndrome should not be based exclusively on x-ray or laboratory findings, but principally on clinical aspects. Ophthalmologic and otorhinolaryngologic evaluations are also important in reaching a definitive diagnosis.

Prognosis is good when there is no mental retardation or cardiac abnormalities. The female patient faringeps this case presented with many of the clinical manifestations of this syndrome including facial asymmetry, right microtia with atresia of the external auditory canal, systolic murmur grade 1 and radiographic findings of skeletal alterations. It is very important that every physician, including dermatologists, should be able to identify this syndrome given the possibility that other systemic faringeoa may be present that could affect the patient’s prognosis.
