The Results and Complications of Cranial Bone Reconstruction in Patients With Craniosynostosis

Abstract

The aim of this study was to report the treatment results and complications of cranial bone reconstruction in patients with craniosynostosis at the Seoul National University Children's Hospital over the 14-year period from 1996 to 2009. A retrospective study was undertaken on 96 cases of 94 consecutive patients diagnosed with craniosynostosis, operated on between 1996 and 2009. The authors collected the data regarding age at surgery, operative time, duration of hospitalization, and follow-up period. Surgical results including the amount of blood loss, signs related to increased intracranial pressure, aesthetic results, cranial index, and complications were evaluated. The authors compared these results with those of the past 10-year period from 1986 to 1995 at the same hospital. There were 81 patients with single synostosis and 13 patients with multiple synostoses. The age of patients ranged from 3 months to 130 months (mean, 27.9 months). The mean operative time was 7.54 ± 1.77 hours. The duration of hospital stay ranged from 5 to 70 days with a mean period of 8.97 days. The intraoperative loss of hemoglobin ranged from 0 to 9.2 g/dL (mean, 2.35 g/dL). The symptoms of increased intracranial pressure were improved after cranioplasty. With regard to aesthetic results, 94 patients were classified into category I and 2 into category IV. The cranial index decreased from 88.0% ± 1.2% to 86.9% ± 1.1% on average. There were 34 minor complications in 28 operations (29.2%). There were statistically significant differences in age at surgery, operative time, duration of hospital stay, and reoperation rate between the recent 14-year study and the past 10-year study. We observed good surgical results and low complications of cranial bone reconstruction in patients with craniosynostosis. The results of the recent 14-year operations were better than those of the past 10-year operations.
