The endoscope-assisted minimally invasive retro-sigmoid approach (EAMIRSA) is a surgical technique that can be used for the treatment of the cerebellopontine angle (CPA) and internal auditory canal (IAC) disease. Here, we describe the material necessary to perform EAMIRSA and illustrate the technique using a step-by-step cadaver dissection.
