Children with Metopic Ridge.

A metopic ridge in children is a benign finding, distinct from trigonocephaly. This condition does not require surgery or radiological investigation, representing a mild form of metopic synostosis.
Area of Science:
- Pediatric Neurosurgery
- Craniofacial Surgery
- Developmental Pediatrics
Background:
- Metopic synostosis, or trigonocephaly, results from premature closure of the metopic suture.
- A subset of children present with a metopic ridge without trigonocephalic features.
- Distinguishing these conditions is crucial for appropriate management.
Purpose of the Study:
- To define the clinical characteristics of children with a metopic ridge.
- To differentiate metopic ridge from trigonocephaly.
- To guide diagnostic and treatment approaches for metopic ridge.
Main Methods:
- A retrospective follow-up of 38 children diagnosed with metopic ridge.
- Clinical examinations and photographic documentation were utilized.
- Data collected between January 2010 and November 2015.
Main Results:
- The study included children aged 3-30 months (mean 14 months).
- Boys (65.8%) were more commonly affected than girls (34.2%).
- A midline metopic ridge without fronto-orbital deformity was the sole diagnostic criterion; parental concern was common, and no patients required surgery.
Conclusions:
- Metopic ridge is a distinct pathology of the metopic suture, often causing parental concern.
- Radiological investigations and surgical intervention are not indicated for isolated metopic ridge.
- This condition can be considered the mildest presentation of metopic synostosis.

Sutures 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...
Cranial 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,...
Cranial 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...
