Identifying Risk Factors for Wound Complications Following Fronto-Orbital Advancement in Patients With Craniosynostosis: 3-dimensional Craniometrics Analysis.

Abstract

This study aims to identify 3-dimensional (3D) craniometric predictors of wound complications following fronto-orbital advancement (FOA) surgery in craniosynostosis patients. The authors conducted a retrospective review of medical records for 43 patients (25 female, 18 male) who underwent open FOA between 2006 and 2023, with an average follow-up duration of 91.8 months. The data collected included age at surgery, sex, whether the craniosynostosis was syndromic, involvement of multiple sutures, history of suturectomy, wound complications (categorized as minor or major), and preoperative and postoperative 3D CT scans. The authors quantified relative changes in intracranial volume (ICV), cranial area above the Frankfurt Horizontal plane, anteroposterior diameter (APD), and cranial height (CH) using Mimics software. A logistic regression analysis was performed to identify predictors of wound complications post-FOA. Among the 43 patients who underwent FOA, 10 experienced postoperative wound complications (4 minor, 6 major), revealing significant associations with multisuture involvement and changes in △cranial area, △APD, and △CH (all P<0.05). In the multivariable analysis with backward elimination, △cranial area, and △CH were identified as significant risk factors for wound complications (OR 1.17, 95% CI: 1.01-1.36, P=0.032; and OR 0.59, 95% CI: 0.38-0.92, P=0.019, respectively). The cutoff values for △cranial area and △APD were 5.95% and 7.93%, respectively. This study identified measurable craniometric changes, especially in the cranial area, as risk factors for wound complications following FOA. It underscores the necessity for personalized surgical planning and meticulous postoperative wound care in FOA to enhance patient outcomes through risk-aware strategies.
