Purpose
To evaluate the long-term anthropometric measurements, cosmetic satisfaction, and other patient-reported outcome measures (PROMs) of patients who underwent surgical treatment or observation only of sagittal or metopic single-suture craniosynostosis (SSC).
Methods
A prospective study was designed for all patients diagnosed with non-syndromic sagittal and metopic craniosynostosis at the British Columbia Children’s Hospital, Vancouver, Canada, in the period July 1986 to July 2006. After a minimum of 15 years post-diagnosis, all eligible patients were invited to fill out the Craniofacial Surgery Outcomes Questionnaire (CSO-Q) and to attend a scheduled follow-up appointment for the collection of anthropometric measurements. A descriptive analysis of the cosmetic results was performed. Statistical analyses compared the differences in anthropometric measurements between treated and non-treated patients.
Results
Of the 253 eligible patients, 52 participants were willing to share patient data for use in the study. Of those 52 former patients, 36 (69.2%) filled out and returned the CSO-Q and 23 (44.2%) attended the follow-up appointment. The mean follow-up period between surgical treatment and the CSO-Q was 20.2 ± 2.5 years and between surgical treatment and the follow-up appointment was 20.9 ± 2.7 years. In patients with sagittal SSC, the mean cephalic index (CI) was significantly larger in treated than in non-treated patients (74.6 versus 69.1, p = 0.04), while the mean pupillary distance and forehead to back index were significantly smaller (pupillary distance 6.0 cm versus 6.7 cm [p = 0.04] and forehead to back index 19.6 cm versus 21.1 cm [p = 0.03]). Focusing more on the patient reported outcome measures, overall cosmetic satisfaction was found to be high (80.6%) and no differences were found between sagittal and metopic synostosis patients, nor between treated or non-treated craniosynostosis patients. Overall outcomes regarding self-esteem (RSES) and fear of negative evaluation (FNE) were comparable with population based outcomes.
Conclusion
This is the first prospective study of sagittal and metopic craniosynostosis patients regarding long-term anthropometric outcome and patient reported outcome measures, including patients who were treated surgically and those who received observation only. Although study participation two decades after initial diagnosis was difficult to obtain, our data provide a platform from which one can develop an inclusive and uniform approach to assess patients’ subjective cosmetic satisfaction using the CSO-Questionnaire and might be useful in preoperative counseling and psychosocial care for patients and their families.
