Correction of sagittal synostosis using a modified Pi method

The authors' technique for the treatment of sagittal synostosis, which involves total cranial vault reconstruction and is termed the Pi procedure, is a safe, effective method for correcting the deformities associated with sagittal synostosis. It provides an immediate correction that does not require any further manipulations to the skull, such as a molding helmet. The technique addresses all the aspects of the deformity. It increases the width as well as the central height of the skull and decreases the length of the skull to produce a rounder cranial vault.
