Retrosigmoid approach for the resection of a large choroid plexus papilloma: Three-dimensional operative video
The semi-sitting retrosigmoid approach offers direct access to the cerebellopontine and cerebellomedullary angles, enabling precise dissection of critical neurovascular structures in a clear surgical field. This operative video illustrates key anatomical and technical considerations, supporting the approach as a safe and effective strategy for complete tumor resection and favorable long-term outcomes. The patient provided informed consent for the procedure and publication.
