We report on a 20-month-old boy with skull malformations and motor delays. A diagnosis of Saethre-Chotzen syndrome was made in view of the clinical and neuroradiological signs. Other unusual findings were trigonocephaly and occipital dysplasia with medial schisis at the foramen occipitalis. The mother showed a mild expression of the syndrome.
Both upper and lower airway compromise may be responsible for early death in some patients with the Apert syndrome. We report on two and review six cases with complete or partial cartilage sleeve abnormalities of the trachea. Possible mechanisms include tracheal stenosis and/or lack of tracheal distensibility which may result in respiratory inefficiency, inability to clear secretions, and/or increased liability to surface injury from tracheal suctioning. Upper airway compromise, consisting of obstructive sleep apnea and cor pulmonale, may result from reduced nasopharyngeal and oropharyngeal dimensions in the Apert craniofacial configuration.
Radiographs of the cervical spine--in many cases longitudinal--were available for study in 68 cases of Apert syndrome. Autopsy material was available in one of these cases, and a 3-dimensional reconstruction from a CT scan was also studied in one case. Variable degrees of fusion were observed, involving the articular facets, the neural arch or transverse processes, or block fusion of the vertebral bodies. Ossification may not always be evident in some early radiographs. However, early radiographic signs of impending fusion may be irregularity in vertical orientation of the vertebral bodies and narrowing of the involved intervertebral spaces. Cervical fusions occurred in 68%, single fusions being found in 37%, and multiple fusions in 31%. C5-C6 fusion was most common, alone or in combination with other fusions. In contrast, cervical fusions are known to occur in 25% of Crouzon patients, most commonly involving C2-C3 only. It appears that when fusions are present, C5-C6 involvement in the Apert syndrome and C2-C3 involvement in the Crouzon syndrome separate the 2 conditions in most cases. Because cervical anomalies may complicate an already compromised airway in any form of acrocephalosyndactyly, it is imperative to initiate radiographic study of the cervical spine before undertaking anesthesia for surgery.
