Stepwise Reconstruction of a Large, Self-Inflicted Calvarial Defect

Large calvarial defects pose significant reconstructive challenges due to the need for both structural support and tissue coverage. Scalp expansion is a well-established method to generate adequate tissue for resurfacing. However, cases involving self-inflicted injury and concurrent infection complicate treatment planning. Prior research has shown that tissue expansion can improve outcomes in complex reconstructions. No prior work had resolved the combined challenges of infection, dural violation, and soft tissue deficiency in such cases. This gap motivated the development of a staged reconstructive strategy. The patient’s condition required simultaneous infection control and tissue generation. Traditional single-stage approaches may not suffice in these scenarios. This paper contributes a case study with a unique injury mechanism and treatment pathway.

The goal was to manage a large calvarial defect caused by self-inflicted injury and associated infection. The patient presented with a full-thickness wound and dural violation. Immediate debridement was necessary to prevent further neurological damage. The presence of MSSA bacteremia and intracranial abscess required urgent intervention. The reconstructive challenge extended beyond structural repair to include tissue generation. Scalp tissue expanders were used to address soft tissue deficiency. The study aimed to document the stepwise cranioplasty approach. The case highlights the complexity of managing combined infection and tissue loss.

The patient underwent emergency debridement and dural coverage using a scalp rotational flap. Subsequent treatment focused on infection control and tissue expansion. Multiple scalp tissue expanders were implanted over several months. The expanders were gradually inflated to generate sufficient tissue. This approach allowed for delayed cranioplasty once infection was controlled. The surgical team prioritized both structural and aesthetic outcomes. Tissue expansion was performed in stages to minimize complications. The reconstructive plan was adjusted based on the patient’s clinical response.

The initial debridement successfully covered the dural defect and reduced infection risk. Tissue expanders were placed and inflated over a 6-month period. The generated tissue provided adequate coverage for cranioplasty. No major complications arose during the tissue expansion phase. The patient’s infection resolved with appropriate antibiotic therapy. The stepwise approach allowed for safe and effective reconstruction. The final cranioplasty restored cranial structure and scalp appearance. The patient’s mental status improved following successful treatment.

This case demonstrates the effectiveness of a staged reconstructive approach in managing complex calvarial defects. The combination of immediate debridement and delayed tissue expansion proved beneficial. The authors propose that this method can be adapted for similar cases. The presence of infection necessitated a careful, stepwise strategy. The use of scalp tissue expanders was critical for tissue generation. The patient’s recovery supports the viability of this approach. The case highlights the importance of individualized treatment planning. The authors suggest that this method may offer advantages over single-stage reconstruction.
