Most cases of Goldenhar syndrome are sporadic; however, familial cases have been reported with autosomal dominant inheritance and variable expressivity. 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.
Rio Branco, 39 Review of the etiologic heterogeneity of the oculo-auriculo-vertebral spectrum hemifacial microssomia. With respect to dental and facial abnormalities, facial asymmetry or hemifacial microsomia are always present in patients with this syndrome.
A nine-year-old girl, the farinyeos of a healthy and non-consanguineous couple, was referred with delayed neuropsychomotor development. Jena A K, Arxos R.
The classic triad associated with the syndrome includes the presence of limbal dermoids, preauricular skin tags and pretragal fistulas. Her parents reported no abnormalities and no drug use during pregnancy. Cases with consanguinity between parents have also been reported, suggesting autosomal recessive inheritance. Cardiac alterations consist of isolated ventricular septal defects or atrial farngeos defects, pulmonary stenosis and tetralogy of Fallot. Vertebral skeletal anomalies include occipitalization of the atlas, spina bifida and kyphosis.
Eur J Hum Genet. Treatment depends on the patient’s age and systemic manifestations, with a multidisciplinary approach often being required. Anormalidades vertebrais podem ocorrer. The female patient in 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.
Oculoauriculovertebral spectrum with radial defects: The patient had a normal karyotype 46 XX. Facio-auriculo-vertebro-cephalic spectrum of Goldenhar syndrome.
Goldenhar syndrome with unusual features. Diagnosis of Goldenhar syndrome should not be based exclusively on x-ray or laboratory findings, but principally on clinical aspects.
J Clin Pediatr Dent. Vertebral abnormalities may occur. Clinical examination revealed low stature and facial asymmetry with the right hemiface smaller than the 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 Ophthalmologic and otorhinolaryngologic evaluations are also important in reaching a definitive diagnosis.
Do you know this syndrome? 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. Central nervous system abnormalities in patients with oculo-auriculo-vertebral spectrum Goldenhar syndrome.
Goldenhar syndrome oculo-auriculo-vertebral syndrome is a rare congenital abnormality that involves the first and second branchial arches. It is very important that every physician, including dermatologists, should be able to identify this syndrome given the possibility that other systemic alterations may be present that could affect the patient’s prognosis.
The etiology of the syndrome is heterogeneous. A depressed scar was also found on the patient’s nose at the site of a previous apocrine hidrocystoma. Services on Demand Journal. Report of fourteen Brazilian cases and review of the literature.
Computed tomography of the paranasal sinuses revealed an asymmetry of the jaw and zygomatic bone on the right side. It consists of abnormalities involving the first and second branchial arches. Prognosis is good when there fariingeos no mental retardation or cardiac abnormalities. Computed tomography of temporal bones showed agenesis of the right external auditory canal and absence of pneumatization of the ipsilateral mastoid air cells, mild hypoplasia of the right ossicular chain, with deformity of the middle ear.
It may also be related to abnormal vascular supply to farinveos first and second arch affecting the formation of the vertebral and branchial systems.
Goldenhar syndrome is a sporadic or inherited genetic syndrome characterized by limbal dermoids, preauricular skin tags and mandibular hypoplasia. How to cite this article. Goldenhar’s Syndrome – case arcks. Conventional lumbar spine radiography revealed an incomplete fusion of the posterior elements of S1.
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. Diagnosis should be based principally on clinical aspects, which should be associated with the patient’s systemic conditions and faringwos findings.
Echocardiogram findings indicated a discrete thickening of the aortic valve with slight regurgitation.
