Resumo

© 2025 Elsevier LtdBackground and objectives: The pterional craniotomy (PT) is a widely used neurosurgery approach that provides access to various intracranial structures. This study compared the exposure provided by 2 techniques for temporalis muscle mobilization: interfascial dissection (IF) and myocutaneous flap (MF). Methods: Eight adult cadavers underwent sequential craniotomies on the left side using both techniques. The measurement areas of surgical exposure, angular exposure, and linear exposure of the basilar artery were determined. Results: Results showed no significant difference in the total area of exposure or linear exposure of the basilar artery between the IF and MF. However, interfascial dissection provided significantly greater vertical angular exposure. Conclusion: Although both techniques offer comparable horizontal exposures, the choice between them should consider the anticipated working angles. The interfascial temporalis flap may be preferred for broader vertical exposure is required.
