Autologous bone fragments for skull reconstruction after microvascular decompression

Area of Science:

• Neurosurgery
• Plastic and Reconstructive Surgery

Background:

• Skull reconstruction after microvascular decompression (MVD) involves various techniques with distinct pros and cons.
• Evaluating the efficacy of autologous bone fragments for cranial defect repair post-MVD is crucial.

Purpose of the Study:

• To assess the safety and effectiveness of using autologous bone grafts for skull reconstruction after MVD.

Main Methods:

• Retrospective analysis of 145 patients undergoing MVD and autologous bone graft reconstruction between September 2020 and September 2021.
• Review of clinical data and follow-up imaging (cranial CT) to evaluate reconstruction outcomes.

Main Results:

• Low complication rate: 2.06% with delayed wound healing; no cases of cerebrospinal fluid leakage, incisional dehiscence, or infection.
• Excellent long-term skull reconstruction observed in 58.62% of patients via 1-year postoperative CT scans.
• Evidence of new bone formation in the cranial defect area in patients requiring re-operation for MVD recurrence.

Conclusions:

• Autologous bone fragments are a safe and viable option for skull reconstruction post-MVD.
• The procedure is associated with minimal postoperative wound complications.
• Excellent and durable long-term cranial repair outcomes are achievable with this method.
