Abstract

Objectives: Endoscopic–assisted surgery combined with the operating microscope has been described for several surgical techniques and pathologies of the cerebellopontine angle (CPA). The use of an endoscope allows for a panoramic view of the CPA cistern and a high degree of maneuverability in narrow cisternal spaces that enable the surgeon to deal with most CPA lesions safely. We performed an observational study to describe the surgical anatomy and technique for endoscopic-assisted CPA surgery, describing our experience in a case series of patients with CPA pathology. Methods: Anatomical and surgical technique description of endoscopic-assisted surgery for CPA pathology, based on observations on a case series of patients surgically treated with an endoscopic–assisted keyhole retrosigmoid craniotomy. Results: Ten patients were treated with the following diagnosis: Trigeminal neuralgia (5 patients), epidermoid cyst (2 patients), hemifacial spasm (1 patient), vestibular paroxysms (1 patient), CPA neurocysticercosis (1 patient). The mean age was 48 years old, seven female and three male patients. All patients had resolution or improvement of their clinical symptoms. We describe the anatomic corridors for endoscopic–assisted surgery and surgical pearls. Conclusions: Endoscopic-assisted microsurgery of the CPA is a safe and efficient procedure that has demonstrated improved surgical results as compared to the full-microscopic technique.
