Summary
Microvascular free flaps are effective for reconstructing large skull base tumors after surgery or radiotherapy. This study shows a low flap failure rate and manageable local recurrence in 23 patients.
Area of Science:
- Neurosurgery
- Head and Neck Surgery
- Plastic and Reconstructive Surgery
Background:
- Large vault and skull base tumors often necessitate wide surgical excision.
- Reconstruction following such extensive resections typically involves microvascular free tissue transfer (free flap).
Observation:
- This study evaluated 23 patients who underwent reconstruction with free flaps for large vault or skull base tumors.
- Eight patients had prior surgery elsewhere, and seven had recurrent disease post-radiotherapy.
Findings:
- The study reported a single flap failure (1/23).
- A local recurrence rate of 16% (3/19) was observed in evaluable cases.
- At a mean follow-up of 29 months, 19 patients were alive, with four deaths.
Implications:
- Microvascular free flap reconstruction is a viable option for complex skull base tumor resections.
- The technique demonstrates acceptable outcomes even in previously treated or recurrent cases.
- Further research may optimize oncological control and functional recovery in these challenging reconstructions.
