Summary
Galeal flaps offer a reliable solution for complex skull base reconstruction, demonstrating low complication rates and successful outcomes in a large patient cohort. These flaps are versatile for various defect sizes and locations.
Area of Science:
- Neurosurgery
- Plastic Surgery
- Reconstructive Surgery
Background:
- Skull base reconstruction is critical for patient survival.
- Galeal flaps are increasingly utilized for these complex reconstructions.
Purpose of the Study:
- To describe surgical techniques using various galeal flaps.
- To report on the outcomes of galeal flap procedures for skull base reconstruction.
Main Methods:
- Retrospective review of 136 patients undergoing skull base reconstruction with galeal flaps.
- Dural defects repaired with fascial patches; skull base defects covered with galeal flaps based on size and location.
- No routine spinal drainage was employed.
Main Results:
- Successful reconstruction in all patients.
- Various galeal flaps utilized: galea frontalis (n=17), temporoparietal (n=95), temporoparietal with bone (n=9), bipedicled temporoparietal (n=15).
- Low complication rates: scalp wound necrosis (5.9%), transient CSF leak (2.2%), intracranial infection (1.5%); no galeal flap necrosis.
Conclusions:
- Galea is a well-vascularized, uniformly thick tissue.
- The extensive coverage of the galea allows for versatile flap elevation to address diverse skull base defects.
- Galeal flaps are effective for skull base reconstruction.
