This suture runs from the top of the head down the middle of the forehead, toward the nose. Trigonocephaly (metopic synostosis) This type of craniosynostosis causes a vertical ridge to develop on the forehead. The eyes may be close together, and the forehead may look pointed and narrow. In our patient population, endoscopic surgery for metopic craniosynostosis had an improved safety profile versus open surgery based on reduced procedure length, estimated blood loss, volume of blood transfusion, and length of stay in the ICU and hospital. The main sutures of the skull are the sagittal, metopic, coronal and lambdoid. Metopic suture synostosis is now the second most common type of single suture synostosis and predominantly affects males. The specific abnormality of the head shape depends on which suture(s) is closed. This procedure is available for all forms of craniosynostosis, including sagittal, metopic, coronal, and lambdoid synostosis. The type of craniosynostosis will dictate the way in which the skull shape forms as a result of the growing brain underneath. Many types of craniosynostosis require surgery. For all suture types, 100 (53%) children underwent endoscope-assisted craniosynostosis surgery and 32 (47%) patients underwent open repair. When needed, a surgical procedure is usually performed during the first year of life. The authors looked at primary anthropometric outcomes in head shape at 5 years after surgery as well as peri-operative factors around the time of the surgery. The goal of treatment is to restore a normal contour to the forehead and upper portion of the eye sockets. The surgery is immensely safer than it was in previous decades, but it is a longer overall procedure — it … All centers still offer traditional surgery, particularly for babies who are diagnosed at later ages or babies who have particular types of craniosynostosis with more extensive deformities. Benefits of Endoscopic Surgery Benefits include much shorter scars, decreased time in the hospital and a much lower need for blood transfusions. Fronto-orbital surgery for metopic and unilateral coronal synostosis. treatment of metopic suture synostosis is done via a single incision placed behind the infant's hair line and across the mid-line.. The . The surgical procedure is meant to relieve pressure on the brain, correct the craniosynostosis, and allow the brain to grow properly. An abnormal head shape is noticed after birth. In this video, Dr. Richard Hopper explains how fronto-orbital surgery can repair a metopic suture or a coronal suture on 1 side of a baby’s head (unilateral coronal). Premature closure leads to a forehead that has the shape of a triangle and is known as trigonocephaly. The metopic suture is located on the midline, on top of the skull and extends from the soft spot to the root of the nose. Craniosynostosis occurs in 1 in 2,000 to 1 in 2,500 live births. It is caused by fusion of the forehead (metopic) suture. The endoscopes are used to elevate the baby's scalp over the suture from the anterior fontanel down to the root of the nose (nasion). Ha et al (10.1542/peds.2020-0238) share with us the results of 31 consecutive non-syndromic infants with isolated metopic craniosynostosis who received open correction or endoscopy. Males are slightly more commonly affected than females (3:2). Metopic craniosynostosis can be treated with either strip craniectomy with use of molding helmet after surgery or fronto-orbital advancement, depending on the deformity. Craniosynostosis causes the head shape to be deformed, and in certain instances, can prevent the brain from having enough room to grow. These reported on 111 unique patients with metopic, 65 with unilateral coronal, and 12 with lambdoid craniosynostosis.
