Summary
Vascularized, free-tissue transfer is now preferred for complex anterior cranial base reconstruction, showing similar complication rates to traditional methods despite increased resection complexity. This technique offers a safe and effective solution for challenging cases.
Area of Science:
- Neurosurgery
- Plastic Surgery
- Otolaryngology
Background:
- Reviewed 135 patients with malignant tumors of the anterior cranial base (1976-1999).
- Analyzed reconstruction methods and complication rates over two distinct time periods.
Purpose of the Study:
- To evaluate the efficacy and safety of free-tissue transfer versus conventional pedicled flaps for anterior cranial base reconstruction.
- To compare complication rates and resection complexity between the two reconstruction modalities.
Main Methods:
- Compared free-tissue transfer (6.6% in 1976-1991, 40% in 1992-1999) with conventional pedicled flaps.
- Assessed complex resections involving dura, brain, or adjacent structures.
- Analyzed flap loss and major complication rates.
Main Results:
- Free-tissue transfer showed no flap loss.
- Major complication rates were similar: 31% for free-tissue transfer vs. 35% for pedicled flaps.
- Free-tissue transfer was used for significantly more complex resections (72% vs. 26%, p < .001).
Conclusions:
- Vascularized, free-tissue transfer has become the preferred method for complex anterior cranial base reconstruction at this institution.
- Free-tissue transfer provides comparable safety to conventional techniques, even with more extensive and complex resections.
- This modality is effective for defects involving dura, brain, orbit, palate, and other adjacent structures.
