Incidence of Ocular Abnormalities in Metopic Craniosynostosis: Cranial Vault Reconstruction Versus Endoscopic Suturectomy

ObjectiveTo compare the incidence of ocular abnormalities in patients with metopic craniosynostosis (MCS) treated with cranial vault reconstruction (CVR) versus endoscopic suturectomy (ESC).DesignRetrospective cohort study using the TriNetX Research Network.SettingMulti-institutional electronic health record database.Patients, ParticipantsA total of 588 pediatric patients with non-syndromic MCS (441 CVR, 147 ESC) were identified by ICD-10 and CPT codes. Propensity score matching and age adjustment were performed to reduce confounding.InterventionsSubjects underwent either CVR or ESC. Ocular and surgical complication outcomes were assessed.Main Outcome Measure(s)Primary outcome is ocular abnormalities. Secondary outcomes include surgical complications and reoperations.ResultsOcular abnormalities were present in 40.31% of MCS patients. CVR was associated with a significantly higher incidence compared to ESC (44.67% vs 27.21%; RR = 1.64; 95% CI: 1.23-2.18). CVR patients had greater rates of strabismus (15.19% vs 7.48%; RR = 2.03; 95% CI: 1.10-3.74), ametropia (29.71% vs 11.56%; RR = 2.57; 95% CI: 1.58-4.20), and astigmatism (15.87% vs 2.72%; RR = 5.84; 95% CI: 2.17-15.70). These differences remained significant after adjusting for age and matching by sex, race, and ethnicity. The ESC group showed ocular outcomes comparable to the general pediatric population.ConclusionsPatients with metopic craniosynostosis have a high rate of ocular abnormalities, and there may be a difference between those who undergo CVR versus ESC. These findings underscore the need for routine ophthalmologic surveillance and future prospective studies are needed to confirm the findings.
