Anterior skull base approaches have included endoscopic or open microsurgical approaches for intracranial pathologies. However, discussion of a combined hybrid, cranioendoscopic approach, leveraging the benefits of both techniques, has been limited. Here we describe a case of a combined endoscopic, endonasal, and open microsurgical frontotemporal approach for resection of a complex anterior skull base lesion. A 62-year-old man with a large meningioma extending intradurally through the cribiform plate and sphenoethmoidal sinuses underwent a cranioendoscopic resection. Surgical techniques, including repair of the anterior skull base defect as well as complication avoidance and the coordination of multiple surgeons, are discussed.

Endoscopic and open microsurgical approaches for pediatric patients are useful for a wide variety of skull base pathologies. A hybrid, cranioendoscopic approach may be beneficial in improving surgical resection for complex lesions. A case of a 13-year-old boy with a large juvenile nasopharyngeal angiofibroma extending through the nasopharynx and pterygopalatine fossa into the maxillary, sphenoid, and cavernous sinuses is demonstrated via an endoscopic, transnasal and frontotemporal, extended middle cranial fossa microsurgical approach. Management of a large pediatric tumor via narrow nasal passages, safe surgical resection around critical neurovascular structures, and complication avoidance is demonstrated.
