Intradural jugular tubercle reduction to enhance exposure via the transcondylar approach: technical note.

OBJECTIVE: The jugular tubercle can present an obstruction to adequate visualization of posteroinferior cerebellar artery (PICA) or vertebrobasilar junction aneurysms approached via a far lateral transcondylar approach. Reduction of the tubercle via an intradural approach was performed to enhance exposure. The technical details of this maneuver are discussed and demonstrated. METHODS: Two patients with PICA aneurysms were treated via the far lateral transcondylar approach. Intradural reduction of the jugular tubercle was performed to enhance exposure in each case. RESULTS: Exposure of the parent artery and aneurysm was enhanced in each case by intradural reduction of the jugular tubercle, providing several millimeters of added space. Both PICA aneurysms were successfully clipped with no intraoperative complications. CONCLUSION: Several millimeters of additional exposure can be obtained when treating a PICA or vertebrobasilar junction aneurysm via the far lateral transcondylar approach by removing the jugular tubercle via an intradural approach.

Surgical approaches to suprasellar and parasellar tumors.

Uncommonly, pituitary tumors require a complex intracranial approach. In such instances of extensive para- and suprasellar involvement, an approach that incorporates basic techniques enhanced by developments in contemporary cranial base surgery is effective. Tumors with extensive invasion of the cavernous sinus unilaterally are generally best approached by a frontotemporal transcavernous strategy. Those with bilateral cavernous sinus involvement are better suited for a bifrontal transbasal type of approach. Supra-sellar tumors are best exposed by a strategy that affords the surgeon an adequate inferior-to-superior viewing angle, which is generally accomplished by removal of all or part of the orbital rim. These approaches yield benefits in decreased frontal lobe retraction, which may be particularly important in cases requiring a bilateral approach. Finally, some tumors with more modest extensions outside the bounds of the sella are now treated with a more minimalistic type of approach via a small incision in the eyebrow. This marks a move toward a "minimally invasive" type of strategy. Sound judgment based on adequate experience with these approaches must be exercised to ensure appropriate application of this strategy.

The retrosigmoid approach to acoustic neurinomas: technical, strategic, and future concepts.

The retrosigmoid approach continues to be the most widely employed strategy for the surgical resection of acoustic neuromas. The results with respect to facial nerve function are uniformly reported to be quite high. The great emphasis currently is upon improving results with regard to the conservation of useful hearing. This paper focuses on the anatomical and strategic surgical factors that we currently consider to be important to maximizing our current results. The future aspects of this trend toward improved success in conserving hearing in these patients is also discussed.
