Abstract
Objective The pretemporal transcavernous approach is an elegant technique that provides exposure to the basilar apex, which is conventionally completed with a frontotemporal incision. This can also be performed via a minimally invasive eyelid transorbital approach, which has unique attributes. This is a proof-of-concept cadaveric study to demonstrate details of the combination of these two approaches.
Design This study is a proof-of-concept study using cadaveric heads.
Setting This study is a proof-of-concept study in a cadaveric laboratory.
Participants A latex-injected cadaveric head.
Main Outcome Measures Detailed dissection was performed and demonstrated in a step-by-step fashion.
Results The eyelid transorbital approach provides the exact exposure required to complete the pretemporal osteotomy including an anterior clinoidectomy and dissection, so that a transcavernous approach can be completed. The basilar apex and its branches can also be accessed via the eyelid transorbital approach, with comparable exposure to the traditional approach; however, the access trajectory is much narrower. It takes advantages of the inferior corridor with a more medial access angle and provides a complementary perspective to the cavernous sinus contents and basilar apex complex.
Conclusion The combination of an eyelid transorbital and pretemporal transcavernous approaches can achieve a deep exposure via a minimally invasive incision, which may add an additional approach to the cavernous sinus and basilar apex regions.
期刊介绍:
The Journal of Neurological Surgery Part B: Skull Base (JNLS B) is a major publication from the world''s leading publisher in neurosurgery. JNLS B currently serves as the official organ of several national and international neurosurgery and skull base societies.
JNLS B is a peer-reviewed journal publishing original research, review articles, and technical notes covering all aspects of neurological surgery. The focus of JNLS B includes microsurgery as well as the latest minimally invasive techniques, such as stereotactic-guided surgery, endoscopy, and endovascular procedures. JNLS B is devoted to the techniques and procedures of skull base surgery.
