Bypass surgery is a special technique used to treat complex internal carotid artery (ICA) aneurysms. The aim of this retrospective study is to provide a comprehensive description of treatment and outcome of complex ICA aneurysms at different ICA segments (cavernous, supraclinoid, ICA bifurcation) treated with bypass procedures. ⋯ Bypass surgery for complex ICA aneurysms is a feasible treatment method with an acceptable risk profile. Patients should be informed of the uncertainty related to improvement of pretreatment cranial nerve dysfunctions.

Review Case Reports
An ectopic recurrent craniopharyngioma of the temporal lobe: Case report and review of the literature.
Ectopic recurrent craniopharyngioma is rare. We present a case of a temporal ectopic recurrent tumor after a trans-eyebrow supraorbital keyhole approach and provide a review of the reported data with basic statistics. ⋯ Ectopic recurrent craniopharyngioma is a rare phenomenon. Meticulous protection of the entire surgical field and careful manipulation of the tumor during resection are required to prevent possible ectopic recurrence. Regular follow-up examinations are strongly recommended to detect any further recurrences. Gross total resection is the treatment of choice for ectopic recurrence.

Review Case Reports
Bilateral blindness following incomplete coiling of a small anterior cerebral artery aneurysm: case report and review of the literature.
Complications after coiling of large, giant, and thrombosed aneurysms because of increased mass effect on surrounding structures have been widely reported. A case of bilateral blindness after incomplete coil embolization of a small anterior cerebral artery aneurysm is rare. We review the potential mechanisms, clinical progression, and proper treatment needs. ⋯ Incomplete aneurysm coiling may result in bilateral blindness, even at a small anterior cerebral artery. Early DSA, steroid therapy, and secondary craniotomy for nerve decompression should be considered promptly for improving clinical outcome before nerve atrophy, although sometimes single steroid therapy is effective.

Case Reports
Second sacral alar screw fixation: anatomic study of three dimensional computed tomography and case report.
S2 alar screw would be an alternative choice without breaking the sacroiliac joint. The aim of this study was to measure radiographic parameters for optimal placement of posterior S2 alar screw for instrumentation and fusion. ⋯ S2 alar screw is an alternative sacral fixation point to provide additional biomechanical stability of lumbosacral constructs. A trajectory with maximum length through the S2 ala can be determined using three-dimensional computed tomography.

Superior semicircular canal dehiscence (SSCD) is caused by a deformity in the arcuate eminence, leading to various vestibular and auditory symptoms that can manifest unilaterally or bilaterally. The aim of the present study was to distinguish the differences in symptoms, treatment options, and outcomes between patients with unilateral and bilateral SSCD. ⋯ Bilateral SSCD might result in different clinical symptoms that are more prevalent compared with unilateral SSCD. The findings from the present series of patients with bilateral SSCD suggest that patient symptoms and history are important in the diagnosis of bilateral SSCD and deciding whether 1 or both dehiscences requires surgical intervention.
