While coronal suture synostosis stops the growth of the forehead and anterior lobe, it also causes the other side to expand forward. This condition, which is caused by the premature closing of the coronal suture, is also known as anterior plagiocephaly. Coronal synostosis is the premature closure of one or both left and right coronal sutures, which extend from one ear to the other. In this type of craniosynostosis, the forehead is recessed, flattened and the eye socket is elevated and tilted. At the same time, you will notice that your baby's eyes protrude and the nose deviates to the opposite side. If your baby is leaning the head sideways to prevent double vision (squint), it is another sign of this type of craniosynostosis and untreated coronal suture synostosis.
For coronal synostosis, release of the closed coronal suture with the help of an endoscope is done by a small incision located halfway between the anterior fontanelle and the ear on the closed side. In all cases, a very small amount of the newborn's hair is removed. The stenosed suture is removed with bone cutting scissors and instruments. Unlike traditional craniosynostosis surgeries, there is no facial and orbital swelling, and the patient feels minimal pain.
