1Goldenhar Syndrome Presented by Lori Kingsbury & Jennifer Klundt DCOM 732 Craniofacial AnomaliesSummer 2010
2Goldenhar Syndrome AKA Oculo-auriculo-vertebral dysplasia (OAV) First described in 1952 by Maurice GoldenharAssociated with anomalous development of the first branchial arch and second branchial arch
3EtiologiesEtiology is unclear; one possible etiology suggested is that there seems to be a deficiency in mesodermal formation or defective interaction between neural crest and the mesoderm.Some factors are believed to be related to the development of the disease. These may include:Drug ingestion (cocaine, thalidomide, retinoic acid and tamoxifen)Environmental factors (insecticides and herbicides)Maternal diabetes
4Prevalence 1 in 5,000 – 25,000 live births Male prevalence Most cases are sporadic1-2% of cases report autosomal dominant transmissionA few families consistent with autosomal recessive have been reported
5Unique Characteristics Usually characterized by unilateral triad of craniofacial microsomia, ocular dermoid cysts and spinal abnormalities
6Eye defectsOcular anomalies occur in about 50% of cases (epibulbar dermoid and lipodermoid are most common)
7Ear defectsAuricular defects are reported in 65% of cases (preauricular tags, microtia, anotia, conductive hearing loss
8Vertibral defectsVertibral anomolies including absence of vertibrae, hemivertebrae, fused ribs, kyphosis & scoliosis.
10Physical Signs/Symptoms Unilateral or bilateral Hemifacial microsomia (HFM)Microtia; chin may be closer to the affected earMicrognathiaFacial cleftingCleft lip/palateHearing lossMissing eye or benign growths of the eye
11Other Health IssuesHeart, kidney, and lung problems are also common in individuals with Goldenhar syndrome. These typically involve one side of the organ being underdeveloped or missing.
12Speech/Language Characteristics Highly VariableLanguage problems – associated with hearing lossSpeech problems –tongue shape, jaw shape and mobility, weakness or difficulty moving side that is smallerHyponasality – clefting of lip and/or palateSwallowing problems – lack of saliva, tongue shape or useAbnormal airways
13Diagnosis No Genetic Test Through identification of physical anomalies Appearance, Skeletal Formations, Hearing DeficitsProfessionals in pediatric medicine, radiology, ophthalmology, otolaryngology, odontology, and neurology contribute to the diagnosis
14Treatment Lowering of jaw on affected side Lengthening jaw Addition of bone to build up cheeksSoft tissue may be added to face3 to 4 operations to rebuild earCan be very complex because there are so many aspects to deal with. Again it depends on the severity of the condition.
15Treatment Treatment of hearing loss or deafness Speech therapy Managing feeding problemsOrthodonticsTreating associated problems like heart or kidney issues
16Normal Lifespan Normal Intelligence PrognosisVERY GOODNormal Lifespan Normal Intelligence15% show a developmental delay or learning difficulties related to the language problems that stem form the hearing loss, but most demonstrate normal intelligence
