Quantitative and qualitative analysis of the working area obtained by endoscope and microscope in various approaches to the anterior communicating artery complex using computed tomography-based frameless stereotaxy: a cadaver study.

摘要: OBJECTIVE: Surgical treatment of aneurysms the anterior communicating artery complex is challenging, owing to its intricate vascular anatomy. Endoscopy a recently rediscovered neurosurgical technique that could lend itself well overcoming some visualization challenges associated with this procedure. The purpose study was quantify and compare working area afforded by microscope endoscope in different surgical approaches using image guidance. METHODS: We performed total 9 dissections, including mini-supraorbital, pterional, orbitozygomatic bilaterally 5 whole, fresh cadaver heads. used computed tomography-based guidance for intraoperative navigation as quantitative measurements. estimated region, both rigid (4.0 mm diameter 18 cm long 0- 30-degree lenses) an operating microscope. Operability qualitatively assessed senior authors. RESULTS: In microscopic exposure, approach provided greatest (204.5 ± 33.9 2 ), compared mini-supraorbital (114.8 26.9 ) pterional (170 20.4 ; P 0.05). CONCLUSION: our model, use endoscope, assistive manner surgery, advantage without loss microneurosurgical techniques dissection or depth perception field. This most prominent when smaller craniotomies were used.
