Modification of Periosteal Flap as Management of Cerebrospinal Fluid Leakage after Frontal Sinus Fracture Surgery in Moderate Traumatic Brain Injury Patients

Main management for the frontal sinus fracture is using the pericranial flap. Pericranial flaps based on the supraorbital and supratrochlear vasculature have previously been used with significant success for the separation of intracranial and extracranial spaces after major trauma. Defect closure was modified due to lack of the frontal periosteum; the graft was made from the temporal side of periosteum to make primary periosteal flap longer. Defect closure could be optimum. Evaluation for 6 months showed a significant improvement without major complications. In this article, we propose a new modification technique as one of promising alternatives.
