Abstract
Summary of Background Data: The craniofacial malformations described by Goldenhar can be associated with congenital anomalies of the vertebrae. This non-random association of abnormalities represents unilateral errors in the morphogenesis of the spine, as well as the first and second branchial arches.
Purpose of the study: The aim of the present study was to determine the prevalence of Goldenhar related conditions in patients with congenital deformities of the spine and to describe the types of vertebral abnormalities and the necessity for treatment.
Material-Methods: We performed a retrospective study of 668 consecutive patients with congenital deformities of the spine. The medical records and spinal radiographs were reviewed and patients with a Goldenhar associated condition were identified. The vertebral anomalies causing the spine deformity were detected on antero-posterior and lateral spine radiographs. The type and site of the craniofacial abnormalities, as well as other musculoskeletal deformities and systemic anomalies were recorded.
Results: Fourteen patients had Goldenhar associated conditions (7 males and 7 females). A thoracic scoliosis was the most common type of deformity occurring in ten patients (71.5%). Eight of these patients had an isolated hemivertebra and the remaining two had a unilateral unsegmented bar with contralateral hemivertebra at the same level. There was only one patient with a lumbar scoliosis and this was due to a hemivertebra. The side of the vertebral anomaly correlated with that of the hemifacial microsomia in five of the eleven patients who had a scoliosis or kyphoscoliosis. A thoracolumbar kyphosis occurred in four patients; two had posterior hemivertebrae, one had wedge vertebrae, and the remaining patient had an anterior unsegmented bar. A thoracolum-bar kyphoscoliosis occurred in only one patient and was due to a posterolateral quadrant vertebra. Klippel-Feil syndrome occurred in six patients (42.8%).
Eight patients (57%) underwent surgical treatment at a mean age of 9.8 years (range: 2.9–19). Four patients had a combined anterior-posterior spine arthrodesis. The remaining four patients had a posterior spinal arthrodesis.
Conclusions. The prevalence of Goldenhar associated conditions in patients with congenital deformities of the spine was 2%. Failures of vertebral segmentation were the most frequent abnormality in the cervical spine, whereas failures of vertebral formation most commonly occurred in the thoracic or thoracolumbar spine.
