metopic ridge - Viral Trends
The metopic ridge is a palpable midline forehead ridge that occurs with the physiological closure of the metopic suture, which may be confused with the ridging due to metopic craniosynostosis with trigonocephaly 1-6. The skull consists of several sutures that typically close at different ages: Metopic Suture – Forehead to nose; usually closes by 12 months Coronal Sutures – From the top of the head to each ear; close around age 2 Sagittal Suture – Midline on top of the head; closes around age 2 Lambdoid Sutures – Back of the head; close after age 2 The metopic suture is usually obliterated by about 7 years of age, in rare cases, it can persist as an anatomical variant and should not be mistaken for a frontal bone fracture. The midline position in the frontal bone and characteristic sutural i...
Understanding the Context
Craniosynostosis (skull anomalies) —the premature fusion of skull bones, can create an abnormal head shape and increased pressure within the skull. There are several types of craniosynostosis, and our surgeons treat all forms, including these categories: coronal synostosis, lambdoid synostosis, metopic synostosis, and sagittal synostosis. Metopic craniosynostosis is a rare condition in infants in which a certain part of the skull fuses earlier than it typically would. The condition can range from mild to severe and cause long-term ...
