Case Reports
Use of intraoperative navigation for reconstruction of the C1 lateral mass after resection of aneurysmal bone cyst.
Aneurysmal bone cysts (ABCs) are rare blood-filled cystic lesions that are found in the long bones and spine. Here, we present a case of an ABC found in the lateral mass and lamina of C1. Lesions in this area provide a surgical challenge because of its difficulty to access as well as its need for reconstruction. We describe a novel use of intraoperative navigation (ION) to assist in the placement of a C1 lateral mass titanium cage. ⋯ ION is a useful aid in assessing the extent of tumor resection and performing cage reconstruction of the C1 lateral mass.

Aberrant internal carotid artery (aICA) is an anatomic anomaly whereby the internal carotid artery courses through the tympanic cavity without separation by bone. Because aICA is rare, there are no definite treatment strategies for aICA and its complications. ⋯ This is the first case report of an aICA complicated by pseudoaneurysm formation successfully treated with simultaneous endovascular trapping and high-flow bypass in a hybrid operating room.

To assess the quality of life (QoL) in a representative sample of patients with vestibular schwannoma and to ascertain the differences in outcomes associated with distinct management strategies. ⋯ The QoL within this patient cohort was extremely variable in each management group, mirroring the heterogeneous natural history of this disease process. QoL in patients with vestibular schwannoma cannot be predicted based on management strategy alone, but a poor QoL outcome is more likely in patients with larger, symptomatic tumors that are treated surgically.

Frameless and Maskless Stereotactic Navigation with a Skull-Mounted Tracker:A Technical Report.
In this series, we present 3 cases that show the use of a skull-mounted tracker for image-guided navigation for anterior skull base surgery and ventricular catheter placement procedures. This system obviates fiducials or face masks during the surgical procedure itself and allows for the performance of facial incisions using the Weber-Ferguson approach. ⋯ Intraoperative image-guided navigation has revolutionized neurosurgery. It undoubtedly increases the surgeon's confidence and the perception of safety. Although fiducials and facial masks are the most widely used tools for intraoperative navigation, their use is associated with certain complications. This technique permits free movement of the head during surgery, which in turn facilitates the exposure of head and neck lesions and expedites the approach to ventricular catheter placement. Our case series shows the precision and ease of our technique, which is less time consuming and less cumbersome than the traditional frame-based stereotaxy. In addition, the skull-mounted tracker system allows improved anatomic localization and shorter operating time and avoids the complications associated with the use of rigid fixating head frames.

This study aimed to determine whether smartphones affect programmable shunts. ⋯ Smartphones exert reversible effects on Strata programmable valves without producing remarkable radiologic findings and irreversible effects on Codman Certas valves.
