Background: Epidural abscesses and subdural empyema after craniotomy are potentially lethal complications in neurosurgery. Patients with recalcitrant cranial wound infections may be difficult to manage, and dural reconstruction in these patients is challenging.
Methods: A total of 14 patients presented with recurrent intracranial infection after craniotomy. The symptoms and signs included persistent fever, despite prolonged systemic broad-spectrum antibiotic administration and repetitive debridement of the dural space. They underwent reconstruction with an omental free flap to cover the craniotomy defect. Microvascular anastomosis is usually performed between the gastroepiploic and superficial temporal vessels. Surgeries were performed in the chronic stages of infection, and the patients were reviewed and assessed for recurrence over the long-term postoperatively.
Results: The postoperative course was uneventful, and flap survival was excellent in all patients. The patients were discharged with no evidence of wound discharge, and there were no reports of infection recurrence, flap failure, or donor site morbidity.
Conclusions: The use of vascularized free omentum flap was effective in cases involving intractable cranial wound infection.
