Abstract
BACKGROUND: Epidermoid cyst in the cerebellopontine angle (CPA) can involve numerous critical structures. Endoscopic assistance following microscopic removal via a retrosigmoid approach can expand the surgical corridor, allowing for more complete resection. METHOD: We describe in a stepwise fashion the surgical steps for the microscopic removal of an epidermoid cyst of the CPA with endoscopic assistance. CONCLUSION: Endoscopically assisted microscopic removal for CPA epidermoid cysts provides wide access to the CPA and its adjacent structures and shows to be an effective option in selected cases.
