Abstract:
OBJECTIVE: The authors report the surgical results of anterior circulation aneurysm surgery by inexperienced neurosurgeon and the results are compared to those of experienced one. METHODS: The pterional approach for the anterior circulation aneurysm was performed on 20 cases from July 2000 to July 2001 by experienced neurosurgeon. The pterional approach and orbitozygomatic with orbital rim osteotomy were performed on 10 cases respectively from Oct 2001 to May 2002 by inexperienced neurosurgeon. RESULTS: All of aneurysms were treated by direct clipping. Good outcomes(Glasgow Outcome Scale score 4 or 5) were achieved in 60%, fair(GOS score 3) 10%, poor(GOS score 1 or 2) 30% through pterional approach by inexperienced neurosurgeon. Good outcomes were achieved in 70%, fair 20%, poor 10% through orbital rim or orbitozygomatic approach by inexperienced neurosurgeon. Good outcomes were achieved in 65%, fair 20%, poor 15% by experienced neurosurgeon. CONCLUSION: The clinical outcomes of anterior circulation aneurysmal surgery through the orbital rim or orbitozygomatic osteotomy by inexperienced neurosurgeon showed no statistical differences compared with routine pterional approach. However, the authors could obtain lesser brain retraction and easy access of the target through the orbital rim or orbitozygomatic osteotomy.
