概要	Endoscopic endonasal surgery (EES) has rapidly evolved as a minimally invasive option for ventral posterior fossa lesions, offering a direct midline corridor while avoiding soft-tissue dissection, cerebellar or temporal lobe retraction, and the extensive petrosectomy required in traditional open approaches. Detailed descriptions of the nasal and skull base exposure, management of high-flow venous and CSF bleeding, and multilayer reconstruction using fascia, rigid buttress, fat graft, and a robust rhinopharyngeal flap. By sharing a reproducible high-resolution strategy grounded in anatomical principles and reconstructive techniques, we aimed to facilitate the safe expansion of EES indications for complex posterior fossa tumors.
