Abordaje minipretemporal transtentorial Trans-Meckel con petrosectomía anterior para Schwannoma del trigémino

Abstract

Trigeminal Schwannoma are low frequency benign tumors, corresponding to 4% of intracranial tumors, unlike vestibular schwannomas, which are seen between 8 and 10%. These tumors can affect the middle cranial fossa, the posterior fossa, or both, which is known as dumbbell-shaped. We present a 54-year-old female patient with a history of hypothyroidism, hypertension and embolized anterior communicating artery aneurysm with symptoms of right V1, V2 and V3 hypoesthesia, plus masseter atrophy. With an imaging diagnosis of right Trigeminal Schwannoma, keeping in control with brain Magnetic Resonance where an increase in tumor growth is noticed, for which surgery is indicated. In this video we show the analysis regarding the pre-operative image, the surgical detail of the microsurgery performed and the post-operative result, emphasizing the Mini-pretemporal route as a safe access for this type of pathology without the need for resection of the zygoma.
