A review of 22 patients with Opitz-C syndrome from the literature is presented. Most of the typical facial dysmorphism can be regarded as part of a trigonocephaly "sequence" rather than presenting characteristic features of a syndrome. [ncbi.nlm.nih.gov]

  • Dysplastic Ears

    She is severely mentally retarded and shows the characteristic findings of this syndrome, including trigonocephaly, unusual facial features, especially intra-oral anomalies, low set and dysplastic ears, cardiac anomaly and neonatal hypotonia. [ncbi.nlm.nih.gov]

  • Angiomatosis

    The cardinal features of Sturge-Weber syndrome are facial cutaneous capillary malformation (port-wine stain), leptomeningeal angiomatosis, and glaucoma. Premature closure of the metopic suture results in trigonocephaly. [ncbi.nlm.nih.gov]

  • Self-Mutilation

    PATIENTS AND METHODS: Fifty-six children (44 boys, 12 girls) in whom ICP was measured were diagnosed with mild trigonocephaly (nonsyndromic type) with symptoms such as language delay, hyperactivity, autistic tendencies, self-mutilation, motor delay, etc [ncbi.nlm.nih.gov]

  • X-Ray Abnormal

    Factors contributing to improvement were younger age, relatively higher development quotient, marked digital impressions on skull X-rays, abnormal findings on SPECT, and moderate degree of trigonocephaly. [ncbi.nlm.nih.gov]

CONCLUSIONS: Early detection and treatment of metopic suture synostosis has a significant, favorable influence on the outcomes. [ncbi.nlm.nih.gov]

The importance of the minor anomalies in its recognition and its good prognosis are emphasized. [ncbi.nlm.nih.gov]

Prognosis In general, a single operation is all that is necessary to treat this condition and the cosmetic and clinical outcomes are usually excellent especially for otherwise healthy, nonsyndromic infants. [skullbaseinstitute.com]

Prognosis The clinical outcome for patients having undergone surgery is usually satisfactory with a low requirement for additional interventions, especially in the mild forms. Recurrence of a prominent metopic ridge may occur in some rare cases. [orpha.net]

However, the concordance rate of isolated trigonocephaly in monozygotic twins is 43%, suggesting that both genetic and environmental factors are involved in the etiology of this disorder. [panafrican-med-journal.com]

The etiology of trigonocephaly is mostly unknown although there are three main theories. Trigonocephaly is probably a multifactorial congenital condition, but due to limited proof of these theories this cannot safely be concluded. [en.wikipedia.org]

Summary Epidemiology Incidence is estimated at 1/15,000 births. Males are more frequently affected than females (sex ratio of 2:1) and the frequency of trigonocephalic twins is unexpectedly high. [orpha.net]

However, because the exact pathophysiology remains unknown, we examined the pathophysiologic mechanisms behind cognitive dysfunction in patients with trigonocephaly, with an aim of providing a model for cognitive dysfunction based on routinely available [ncbi.nlm.nih.gov]

The possibility of coincidence should not prevent continued surveillance of OTS patients in the future for the occurrence of malignancy. [ncbi.nlm.nih.gov]

Conclusion: The early recognition of these anomalies including all craniosynostoses, the deformities of the newborn and infant’s head and the preventive operative reconstruction would prevent abnormal disturbance of the psychomotor development during [degruyter.com]
