Overview
Infection of cranial bone flaps is a serious complication following craniotomy, potentially leading to significant morbidity and mortality due to the precarious blood supply of the flap 1.Diagnosis
Clinical signs include fever, purulent drainage, and signs of systemic infection.
Imaging (CT/MRI) may reveal fluid collections or gas within the flap area.
Cultures from drainage or surgical samples are essential for identifying pathogens 1.Management
Antibiotics: Initiate broad-spectrum coverage (e.g., vancomycin, ceftriaxone) tailored based on culture results 1.
Surgical Intervention: Debridement of necrotic tissue and irrigation of the flap area may be necessary 1.
Close Monitoring: Frequent clinical assessment and laboratory monitoring for signs of sepsis 1.Special Populations
Dark-Skinned Patients: Consider using the fluorescein test in conjunction with a scratch test to assess flap viability 2.Key Recommendations
Early recognition and aggressive management of signs of infection are crucial to prevent complications (Evidence: Strong 1).
Utilize broad-spectrum antibiotics initially, adjusting based on culture and sensitivity results (Evidence: Moderate 1).
For dark-skinned patients, incorporate fluorescein testing alongside clinical assessment to evaluate flap viability (Evidence: Weak 2).References
