Abstract
We present a case of a petroclival meningioma that was resected through an endoscope-assisted
retrosigmoid approach via corridors above and below the facial-vestibulocochlear nerve
complex. The patient is a 61-year-old female with complaints of left-sided hypesthesia
and neuralgia of the infraorbital and zygomatic region, intermittent periorbital myokymia,
and a slight facial palsy (HB II). This 2D video demonstrates the operative technique,
anatomical and surgical nuances of the skull base approach and microdissection of
the tumor from the critical neurovascular structures. A gross total resection was
achieved. The patient’s facial and trigeminal symptoms resolved completely within
a few weeks. At 2 year follow up there was no indication of residual or recurrence.
In summary, the retrosigmoid approach with endoscopic assistance is an important and
powerful tool in the armamentarium for the microsurgical management of meningiomas
of the lateroventral skullbase of the posterior fossa.
