Surgical treatment of ruptured anterior circulation aneurysms: comparison of pterional and supraorbital keyhole approaches.
Recent advancements in microsurgical techniques and instrumentation have allowed the development of the keyhole approach in aneurysm surgery. ⋯ The rate of procedural complications may be higher with the supraorbital keyhole approach, but overall patient outcomes appear to be comparable. The pterional approach is a simple, reliable, and efficient procedure. The keyhole approach may be an acceptable alternative for neurosurgeons who have gained sufficient experience with the technique, especially for small noncomplex aneurysms.
