Aim:The premature closure of the metopic suture results in metopic synostosis, also known as trigonocephaly. However, there is a group of children have only a frontal metopic ridge, obvious with inspection and fingertip palpation, without the clinical features of trigonocephaly. This study aims to report a group of children with metopic ridge with a special emphasis on the definition and the diagnostic features. Material and Methods:Thirty-eight children with a diagnosis of metopic ridge were followed up with clinical examinations and photographs in the pediatric neurosurgery outpatient clinic between January 2010 and November 2015.Results:Children were between 3 and 30 (mean=14) months of age at diagnosis. Twenty-five (65.8%) of the children were boys and 13 (34.2%) were girls. A midline metopic ridge without fronto-orbital trigonocephalic deformity was the only diagnostic criterion. The parent’s concern about the metopic deformity at initial diagnosis was a common feature in every case. Seven (18.4%) of the children had a sibling with either metopic ridge (n=4) or trigonocephaly (n=3). None of the children had worsened or had received surgery in the follow-up period.Conclusion:The metopic ridge is a pathology of the metopic suture and is a concern for parents in the context of craniosynostosis. Radiological investigation and craniosynostosis surgery are unnecessary in children with a metopic ridge.This clinical entity may be considered the mildest form of metopic synostosis.
