“…Some authors [13,14,15,16] recommended excising the dumbbell-shaped tumors with intra- and extracranial involvement in two stages by removing the intracranial part of the tumor using variations of the transcraniotomy approach during the first stage and removing the extracranial part using an extracranial approach at a later stage if it becomes symptomatic. However, the extracranial component usually remains [13,17,18,19]. Ideally, there would be a more minimally invasive and direct approach to the anterior cranial base for complete removal of such tumors with a one-stage resection.…”

Objective: The complete resection of anterior cranial base meningiomas with intra- and extracranial involvement is always challenging. We describe our experience of treating such meningiomas via a purely endoscopic endonasal approach (EEA). Methods: Eight patients with intra- and extradural meningiomas were operated via EEA. In this study, we describe the operative technique, and analyze the degree of resection, complications and the clinical outcomes. Results: The complete resection of meningiomas with intra- and extracranial involvement was achieved in all patients using EEA. Preoperative visual symptoms were improved or resolved in all cases. One patient experienced a postoperative cerebrospinal fluid leak and delayed meningitis. No patient in our series experienced a new neurological deficit after surgery or recurrence in the follow-up period (18–60 months). Conclusion: Our limited experience indicates that EEA is feasible and safe for the complete resection of anterior cranial base meningiomas with intra- and extracranial involvement in one stage in selected cases.

Primary lesions of the hypoglossal canal, such as hypoglossal schwannomas, are rare. No consensus exists with regard to the surgical approach of choice for treatment of these lesions. Usually, lateral transcondylar approaches have been used. The authors describe the surgical anatomy of the midline subtonsillar approach to the hypoglossal canal. This approach includes a midline suboccipital craniotomy, dorsal opening of the foramen magnum and elevation of ipsilateral cerebellar tonsil to expose the hypoglossal nerve and its canal. The midline subtonsillar approach permits a straight primary intradural view to the hypoglossal canal. There is no necessity of condylar resections. The surgical anatomy of the subtonsillar approach is described and illustrated by an example of a case.

Surgical treatment of dumbbell-shaped hypoglossal schwannoma via a pure endoscopic transoral approach

Dumbbell-shaped hypoglossal schwannomas tend to cause lower cranial nerve deficits, facial paralysis and hearing loss. With appropriate preoperative evaluation and careful planning of the perioperative period, complete tumor resection can be achieved via the purely endoscopic transoral approach. The endoscopic transoral approach is an effectice choice for management of dumbbell-shaped hypoglossal schwannomas.
