Readmission and reoperation are risks in the resection of benign cranial nerve tumors (BCNTs). This report analyzes the impact of patient-level and surgical factors on these adverse outcomes. ⋯ Extremes of age were associated with readmission; preoperative steroid use, long operative time, and postoperative length of stay >3 days were associated with reoperation. Surgeons should consider these factors when assessing risk of postoperative complications for BCNTs.

Patients with a ventriculoperitoneal shunt for hydrocephalus often undergo multiple follow-up computed tomography (CT) scans of the head, increasing the risk for long-term effects of ionizing radiation. The purpose of our study was to evaluate the necessity as a routine diagnostic procedure and cost analysis of routine postoperative CT scan of the head after ventriculoperitoneal shunt surgery. ⋯ Routine postoperative head CT scans after fentriculoperitoneal shunting are not necessary in all cases. The reduction of exposure to ionization radiation and the beneficial economic factor are main advantages.

Unfamiliarity with the morphometry of the assimilated C1 lateral mass (C1LM) could make screw placement dangerous. In the present study, we defined the morphometric dimensions of the occipitalized C1LM to provide surgeons with valuable information for preoperative planning. ⋯ Although the hypoplastic C1LM brings limitations to screw insertion to some extent, it is still broad enough to accommodate a screw safely in both female and male patients. Considering the irregularity of the C1LM in patients with OA, the preoperative imaging assessment is critical, and C1LM screw placement should be performed individually.

To evaluate the stability of multiple rod-connector construct designs using a mechanical 4-point bending testing frame. ⋯ Our data indicate that the design, number, and placement of rod connectors have a significant impact on the bending stiffness of a surgical construct. Such mechanical data may influence construct design in primary and revision surgeries of the cervical spine and cervicothoracic junction.

Hydrocephalus is an international disease process that is commonly treated surgically with a ventriculoperitoneal shunt. This device may be prone to malfunction, most commonly from obstruction, disconnection, or infection. ⋯ Hydrocephalus, ventriculoperitoneal shunts, and shunt revisions represent a significant health burden and cost. Here we present an unusual cause of a shunt malfunction caused by bony overgrowth.
