Aim:
The premature closure of the metopic suture results in metopic synostosis, also known as trigonocephaly. However, there is a group of children who 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 parents" 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.

01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
