The Transpetrosal Approaches System in Posterior Fossa Meningiomas Surgery: Rationale and Results
- 1 Downloads
Purpose of Review
This is a retrospective review of 90 patients with a posterior fossa meningioma (PFM) treated between 1996 and 2017 in our two tertiary skull base centers. Patients underwent surgical resection via different approaches. We aimed to show how different surgical approaches may help to reach gross total resection (GTR) and low morbidity, especially on facial nerve function.
PFM is a real surgical challenge with high morbidity and mortality due to the surrounding structures, their common large size at diagnosis, and their potentially invasive behavior. Total resection is the only way to cure people affected. We successfully treated 90 cases of PFM and evaluated different surgical approaches.
GTR is the aim of the surgery as the extent of resection influences the rate of recurrence, which in turn influences the prognosis. Seventy percent (p < 0.001) of surgical patients achieved a GRT with low morbidity and no mortality.

World Neurosurg. 2018. https://doi.org/10.1016/j.wneu.2018.03.194. PFMs present with distinct clinical syndromes based on their location along the petrous face: anterior with trigeminal symptoms, middle with auditory/vestibular symptoms, and posterior with symptoms of mass effect/hydrocephalous. Surgical resection is associated with excellent long-term survival and a low rate of recurrence, which can be managed with radiotherapy.
