Abstract: The concept of using implantable springs in craniofacial surgery was developed to dynamically remodel the cranium at the postoperative period. Springs have been shown as an effective treatment modality especially for single-suture synostosis patients and had several advantages over traditional techniques. This report presents 2 patients with cloverleaf skull and 1 patient with multiple-suture synostosis, with severe lacunae, who showed signs of increased intracranial pressure. Decompression and reconstruction were performed using implantable springs after Pi craniectomy. In all patients, lacunae disappeared and calvarial bones ossified almost completely. The shape of the patients’ cranium improved as well. Implantable springs could be a useful addition to the armamentarium of every craniofacial surgeon.
