Objectives To describe the operative technique for treatment of epidermoid cysts in the cerebellopontine angle (CPA).
Design The present video is a case report.
Setting Patient is positioned in three-quarters prone. Retrosigmoid approach should be made under neurological monitoring and with neuronavegation to help achieve maximal safe resection. The skin incision is vertical, slightly curved, 5 mm medial to the mastoid notch. Craniectomy is superiorly limited by the transverse sinus and laterally limited by the sigmoid sinus. A C-shaped durotomy is made with its base protecting the sigmoid sinus. The lesion is removed in piecemeal fashion (Fig. 1). The neurological monitoring helps.
Results The patient was discharged 2 days later without neurological deficits.
Conclusions The surgical treatment associated with neurological monitoring and neuronavegation is a safe procedure to treat epidermoid cysts in the CPA.The link to the video can be found at: https://youtu.be/sEuFyq9c2sw.
