“…The diagnosis of metopic suture synostosis remains controversial. 20 Although some reports have stated that the metopic ridge alone is not pathological, 5,21–23 others have suggested that the intracranial volume of the forehead area is small and that surgery is indicated. 24 However, all previous studies have focused on the anterior forehead and orbits.…”

Background: Craniosynostosis, a common congenital anomaly, results from premature fusion of the cranial sutures. One of the forms of craniosynostosis is premature fusion of the metopic suture, referred to as trigonocephaly, but the diagnosis of metopic suture synostosis remains controversial. The purpose of this study was to clarify, using geometric morphometric analysis, if a metopic ridge alone observed in cases of mild trigonocephaly represents a pathological phenomenon. Methods: Three different cranial morphologies were compared among patients up to 2 years old who were categorized into the true group, the mild group, and the normal group, based on the presence or absence of specific symptoms, history of cranioplasty for trigonocephaly, or lack of any abnormality on computed tomography. Using the obtained computed tomography images, 235 anatomical landmarks and semi-landmarks were plotted on the entire cranial surface for analysis of neurocranial morphology, and the cranial shapes represented by landmarks were analyzed using geometric morphometrics. Principal components of shape variations among specimens were then computed, based on the variance–covariance matrix of the Procrustes residuals of all specimens, and statistically analyzed. Results: The principal component analyses of the variations in endocranial shape, frontal bone shape, and occipital bone shape did not show any significant differences in cranial morphology between mild trigonocephaly and normal skulls; however, true trigonocephaly was found to differ significantly from mild trigonocephaly and normal skulls. Conclusions: These findings suggest that in assessments of cranial morphology, the presence of a ridge alone cannot be diagnosed as fundamentally pathological, and may represent normal morphology.

Metopic ridge (MeR) is a midline osseous forehead prominence resulting from physiologic closure of the underlying metopic suture. This mass‐like ridge can be mistaken for serious conditions such as a craniosynostosis or vascular anomaly, prompting concern and workup. We reviewed patients presenting for a forehead mass to Vascular Anomalies and Dermatology clinics and diagnosed with MeR to increase familiarity with this finding and to encourage MeR in the differential diagnosis of pediatric midline forehead masses.

The timing of suture closure and clinical implications of the metopic suture are still unknown. Premature fusion, causing craniosynostosis, happens rarely, but it may result in serious complications, such as craniofacial dysmorphology and neurodevelopmental problems. The clinical significance of metopism is still uncertain. The aim of this study was to review the literature and identify uncertain aspects associated with the formation and clinical implications of the metopic suture. The review showed significant variations in the typical age of metopic suture closure reported in the literature (from five months to seven years). Premature fusion of the suture, usually occurring before birth, may cause skull deformity and developmental disorders. Aetiology is probably multifactorial. Craniosynostosis may result in different phenotypes, ranging from mild changes to trigonocephaly. Diagnosis is achieved based on physical examination and computed tomography scans. Treatment is surgical and aims to achieve two goals: correction of craniofacial dysmorphology and prevention of further complications. Persistence of the metopic suture is diagnosed based on computed tomography scans and is considered to be an anatomical variant. The metopic suture is clinically significant if premature fusion occurs, causing craniofacial and neurodevelopmental disorders. The timing of the closure of the suture, and the aetiology of craniosynostosis and metopism require further research.
