Variants of sagittal synostosis: strategies for surgical correction

Abstract

Sagittal synostosis is discussed with respect to the variations seen with the deformity. The morphological spectrum ranging from marked frontal bossing to prominent occipital bulging is described. Surgical techniques have been specifically designed for these variants. These techniques provide an immediate correction of scaphocephaly, and achieve a reduction of the specific deformity with morbidity comparable to that associated with conventional operations. The lack of large areas of craniectomy and the avoidance of synthetic materials are cited as additional advantages of these techniques. The importance of altering the surgical approach to the specific clinical problem is underscored. Two illustrative cases of sagittal synostosis variants are described, and recent experience with the modified operative techniques in treating these and similar cases is discussed.
