Abstract
It is known that in sagittal syonstosis the cranial morphology generally becomes scaphocephaly or acrocephaly. We had the opportunity to treat a case of sagittal synostosis with brachycephaly and "deformity like saddle" in an 11-month-old boy. Findings of synostosis in the posterior third of the sagittal sutures were observed from X-ray images. Considering the possibility of symptoms due to intracranial hypertension developing in the future, cranioplasty was planned and the operation was performed. Now at 4 months after surgery, good cranial morphology is maintained and symptoms due to intracranial hypertension have not been seen. We report the variety of cranial deformities in sagittal synostosis with bibliographical consideration.
