Subdural hygroma after craniosynostosis remodeling surgery.

Craniosynostosis is defined as the premature fusion of the cranial sutures and can cause functional impairment or cosmetic deformity. Surgical techniques for the correction of craniosynostosis have changed overtime, as so have the intraoperative and postoperative complications. Extensive surgeries involving fronto-orbital unit repositioning and cranial vault remodeling are associated with various complications. Intraoperative and postoperative hemorrhage, venous infarct, air embolism, hydrocephalus, cerebrospinal fluid leak, as well as meningitis are a few complications associated with cranial vault remodeling surgery. Postoperative complications can increase the morbidity and mortality associated with these procedures. Identification of the complications and their timely management should be a part of every craniofacial reconstruction team's training program.In this article, we report a case of subdural hygroma in an infant after cranial vault remodeling procedure. Subdural hygroma is a known complication following head injuries and represents 5% to 20% of posttraumatic intracranial mass lesions. However, subdural hygroma developing after a cranial procedure is rare and has not been reported in the literature. Identification of the complication, close monitoring of the change in subdural fluid volume, and tapping of the fluid through the craniotomy site if indicated form the mainstay of management of subdural hygroma that develops after cranial vault remodeling surgery.
