    Bilambdoid and posterior sagittal synostosis: The Mercedes Benz Syndrome
    (Lippincott, Williams & Wilkins, 1998) Moore, M.; Abbott, A.; Netherway, D.; Menard, R.; Hanieh, A.
    A consistent pattern of craniosynostosis in the sagittal and bilateral lambdoid sutures is described in three patients. The external cranial ridging associated with fusion of these sutures produces a characteristic triradiate, or "Mercedes Benz," appearance to the posterior skull. Locally marked growth restriction is evident in the posterior fossa with compensatory secondary expansion of the anterior fossa manifesting a degree of frontal bossing which mimics bicoronal synostosis. Although this appearance could lead to inadvertent surgery in the frontal region, attention to the occipital region with wide early suture excision and vault shaping is indicated.

    Central nervous system imaging in Crouzon Syndrome
    (LITTLE BROWN CO, 1995) Proudman, T.; Clark, B.; Moore, M.; Abbott, A.; David, D.
    Although the need to prevent the secondary effects of craniosynostosis on the central nervous system is fundamental to the practice of craniofacial surgery, the detailed structural anatomy of the central nervous system in the syndromal craniosynostoses has become the subject of recent interest. A clinical and radiographic review of a population of 59 patients with Crouzon's syndrome determined the frequency of central nervous system deformities. Twelve percent of patients had evidence of decreased mental function. Ventriculomegaly on computed tomographic scan was present in 51% and found to be of three grades: mild, moderate, and severe (hydrocephalus). This was nonprogressive in 7 of the 11 patients with follow-up computed tomographic scans. Ten patients underwent surgical release to increase intracranial space; however, 6 of these patients showed no progression in ventricular size. Nonventricular anomalies were found less frequently (14%). Central nervous system findings show fewer nonventricular anomalies than in Apert's syndrome patients, with a corresponding higher mental function. The principal anomaly of ventriculomegaly is not directly related to suture defect and may represent a primary brain abnormality. Recommendations are made for the assessment and management of patients with Crouzon's syndrome with reference to these areas.

    Extradural deadspace after infant fronto-orbital advancement in Apert syndrome
    (SAGE Publications, 1996) Moore, M.; Abbott, A.
    Infant fronto-orbital advancement is presently a management cornerstone of the craniosynostosis in Apert syndrome. This procedure is based on the premise that the expanding brain rapidly advances in support of, and to remodel, the new frontal facade. This series of infant patients with Apert syndrome undergoing fronto-orbital advancement with early postoperative computerized tomography assessment reveals a large extradural deadspace persistent through the first postoperative week, not obliterated consistently until the fourth week. Early deadspace effacement results from expansion of the prefrontal subarachnoid space, without any significant change in size or shape of the frontal brain substance or ventricles. Brain growth or expansion was particularly slow with brain shape distortions still evident at late follow-up.
