A Surgical Technique for Management of the Metopic Suture in Syndromic Craniosynostosis

The objective is to describe a new surgical procedure developed in the San Jose Pediatric University Hospital for the management of syndromic synostosis of the metopic suture in a patient clinically diagnosed with Saethre-Chotzen syndrome.

The diagnosis of Saethre-Chotzen syndrome, bilateral coronal sutures, and metopic suture synostoses was made through photographic, anthropometric, exophthalmometric, and computed tomography analysis. The keel-like frontal bone deformity was corrected following resection using a fusiform osteotomy, remodelling was obtained by milling the edges, and the bony fragments were repositioned and fixed on the posterior wall of the frontal bone. Additionally, a fronto-orbital advancement with a self-stabilizing bar was performed.

The 1-year postoperative results showed improvement in the position of the fronto-orbital bar, adequate cranial expansion, satisfactory correction of the upper facial third alteration, and correction of the keel-like deformity.

The surgical approach has not previously been described in the literature and offers an alternative management for syndromic craniosyntostosis of the metopic suture, avoiding skull irregularities.
