ABSTRACT

Sagittal synostosis is the most common craniosynostosis. Sagittal synostosis is identified by the characteristic dolichocephaly or scaphocephaly (ie, a. boat-shaped skull with a markedly reduced biparietal diameter but increasing head circumference) that crossed growth percentile lines during the first few months of life. The head is elongated with frontal bossing and an occipital knob or bullet protuberance.
Frequently, a palpable ridge can be appreciated along the longitudinal midline sagittal suture between the anterior fontanelle and junction of the lambdoid sutures. Sagittal synostosis is more common in males (80%). Mental retardation is even less common.
Surgical procedures performed early in the course of premature synostosis have traditionally featured some degree of bone removal, craniectomy, or suturectomy to allow for correction of the deformity coincident with cerebral and cranial growth.
A widely used method to achieve increased (or decreased) curvature is radial osteotomy with molding. A modification of the radial osteotomy technique is the spiral osteotomy, which is commonly used to increase the width of the cranial vault in areas of bone flattening or constriction. We believe that the use of absorbable fixation devices is important to maintain the contour and elevation of the spiral segment as this process occurs.
