Neurosurgical and Clinical Relevance of Microsurgical Anatomy of Cerebellar Para Floccular Perforating Space

Abstract

The cerebellopontine angle (CPA) is a complex, neurovascular area where neoplasms and microvascular pathologies befall. Surgical treatment within the CPA demonstrates the potential risk for ischemic complications within the brainstem and cerebellum. The etiologies of these vascular complications remain unclear, but recent anatomical studies potentially could explain the origin of these events. We reviewed the recent findings and concluded the importance in protecting the perforating vessels during surgical intervention for all pathologies within the CPA.
