Sagittal synostosis is the most common phenotype, representing 40% to 55% of nonsyndromic cases, whilst coronal synostosis represents between 20% to 25% of cases. The procedure and anesthesia time are shorter for the minimally invasive extended strip procedure (2-3 hours anesthesia time) than open procedures (4-6 hours anesthesia time). This is due to expected remodeling after open cranial vault remodeling. 64, 65 Untreated intracranial hypertension may result in insidious optic atrophy, visual loss, and possible developmental delay. Sagittal synostosis: quantitative assessment of presenting deformity and surgical results based on CT scans. The figures below show the location of the bone excision in red and expected movement of the skull bones in blue and green. Sagittal synostosis is the most common form of nonsyndromic synostosis. Both strip craniectomy and open CVR procedures are safe and have equivalent complication and revision rates.

In others, the back of the head may be more significantly affected with a longer, narrow and coned shape. After the procedure a helmet is worn to allow the baby to lie on the back of the head and relieve the pressure from the weight of the head from the parietal bones. Craniosynostosis (CS) is the premature fusion of one or more cranial sutures.It is caused by a mutation in genes that code for fibroblast growth factor. Sagittal synostosis is the most common form of craniosynostosis and represents 40-50% of cases of nonsyndromic suture closure. Sagittal craniosynostosis Sagittal craniosynostosis (also known as scaphocephaly) is the most common type of non-syndromic craniosynostosis and occurs when the sagittal suture fuses before birth.

The locations of bone excision in a minimally invasive extended strip craniectomy are shown in RED. Children with sagittal synostosis who present at an age of older than 4 months are treated with open cranial vault remodeling. Brain growth continues, giving the head a misshapen appearance.Craniosynostosis usually involves fusion of a single cranial suture, but can involve more than one of the sutures in your baby's skull (complex cranio… The first patient has greater compensatory growth in the front of the skull and the second patient has more compensatory growth in the back portion of the skull.

The aim of the present study is to investigate on the association between CM1 and untreated sagittal synostosis (USS). Clinical Features of Sagittal Craniosynostosis: Frontal bossing, elongated cranium (boat-shaped), prominent occiput, palpable keel ridge, normal head circumference, reduced biparietal diameter (skull longer in anteroposterior diameter), reversed slope of cranium.

Open cranial vault remodeling is usually performed between 6-12 months of age. The bones are then reshaped by hand and reattached to one another and the skull with dissolvable sutures or dissolvable plates to correct the head shape. Of the 11 patients with multisuture synostosis, seven included the sagittal and both lambdoid sutures. The present study identified an USS in 27 (15.5%) of 174 CM1 children operated for a symptomatic CM1. Excellent results can be achieved with open cranial vault remodeling, so parents should not despair if their child is diagnosed with sagittal synostosis after age 4 months of age. In his case there is a narrowed bullet-shape (coning) of the back of the head.

As the side bone flaps (parietal bones) move outward the back portion of the skull rotates up and forward like a drawbridge opening. Sagittal synostosis is the most common type of craniosynostosis, accounting for around half of all cases. Open cranial vault remodeling made the back fo the head shorter, taller and wider to provide a normal head shape. When the metopic suture is closed, this … Note that the back of the head is narrower than the forehead which is not normal. The picture on the left shows the same infant with sagittal synostosis demonstrating significant compensatory growth of the forehead. Downsides of sagittal strip craniectomy is that the treatment time is longer due requirement for a molding helmet to be worn for about 1 year.
