title: Roentgencephalometric follow-up after early osteotomies in patients with scaphocephaly.
abstract: The main objective of surgical treatment of scaphocephaly is to improve the shape of the patient's skull. Since 1989 we have used a modified pi-plasty method, and the aim of this report was to study how effective surgery had been. A sample of 25 patients was investigated. All patients were operated on during their first year of life (mean: 6 months). They had roentgencephalometric records preoperatively as well as at a follow-up at age 3 years. Certain measurements were taken from the cephalograms and compared with normative data. It was found that the average skull length had decreased from a preoperative 114% of normal to 107% at follow-up. The skull width had improved from 92% to 98% of normal. The cephalic index had improved as well but was still not within the normal range. The cephalograms were also classified according to the occurrence of digital markings. Before surgery at 6 months none had these signs, but at follow-up every second patient displayed evolution of digital markings. It was concluded that the modified pi-plasty method improves skull morphology considerably but does not completely normalize the shape of the average patient's skull. The cranial length, in particular, needs further improvement.
