Sagittal synostosis: A review of 53 cases of sagittal suturectomy in one unit

SummaryThe role of sagittal suturectomy in the treatment of scaphocephaly remains controversial. The purpose of this study was to report the experience of the National Craniofacial Unit in Dublin. This unit is the referral centre for the Republic of Ireland and serves a population of approximately 3.5 million. Quantitative assessments were made using radiographs and the pre- and postoperative cephalic index (CI) was calculated. Patients were asked to score their head shapes in a questionnaire.The mean age at surgery for the 53 children was 4.9 months with a mean follow up of 8 years. Pre- and postoperative radiographs were available for analysis in 24 patients. The mean preoperative CI was 65.3. There was a statistically significant increase in the CI postoperatively to 73.7. Seventy five per cent of children achieved a 'normal' CI and 86% scored their head shapes as good to excellent. There was no correlation between the age at surgery and the CI achieved. Although only one child was not happy with the shape of the head, the impression was that the CI correlated poorly with the clinical assessment of the head shape. There were no significant complications.We therefore conclude that the sagittal suturectomy is a safe procedure that has a limited but definite potential to improve the CI. This procedure still has a place in the surgical repertoire of the craniofacial surgeon dealing with scaphocephaly.
