Endoscopic skull base surgery is becoming more popular as an approach to the anterior skull base for tumors and cerebrospinal fluid (CSF) fistulae. It offers the advantages of better cosmesis and improved quality of life after surgery. We reviewed the complication rates reported in the literature. ⋯ The endoscopic approach is an increasingly accepted technique for anterior skull base tumor surgery and is associated with acceptable complication rates. Increasing experience with this technique can decrease rates of complications.

Moyamoya disease is a progressive stenosis or occlusion of the internal carotid artery. Revascularization surgery is considered the standard treatment. We conducted a retrospective study in hopes of finding indications for electing different surgical methods. ⋯ Because vascular anastomosis patency in symptomatic patients with moyamoya disease at early Suzuki stage is relatively lower, indirect bypass surgery may be more beneficial for these patients in view of shorter operative time and hospital stay.

Spinopelvic reconstruction after sacrectomy for a sacropelvic tumor can result in various complications and requires a highly complicated surgical technique. We report 2 cases of pelvic reconstruction surgery using diverse U-shaped rods (USRs) after partial sacrectomy. ⋯ A pelvic reconstruction technique using diverse USRs showed good spinopelvic stability without complications. This technique may be a surgical option for reconstructive surgery after partial sacrectomy.

Intramedullary spinal cord tumors (IMSCT) account for about 2%-4% of tumors of the central nervous system. Surgical resection continues to be the most effective treatment modality for most intramedullary tumors, with gross total resection leading to preserved neurologic function and improved survival. However, surgical treatment is often difficult and carries significant risk of postoperative neurologic complications. Intraoperative neuromonitoring has been shown to be of clinical importance in the surgical resection of IMSCT. The main monitoring modalities include somatosensory evoked potentials, transcranial motor evoked potentials via limb muscles or spinal epidural space (D-waves), and dorsal column mapping. These monitoring modalities have been shown to inform surgeons intraoperatively and in many cases, have led to alterations in operative decision. ⋯ By using intraoperative somatosensory evoked potentials, transcranial motor evoked potentials, D-waves, and dorsal column mapping, spinal injury could be prevented in most cases, thereby improving postoperative neurologic functioning and outcome in patients undergoing surgery for IMSCT.

Intracranial neurosurgical disorders are important causes of mortality and disability worldwide. Low tri-iodothyronine (T3) syndrome is a common complication in critically ill patients and is associated with a poor prognosis. ⋯ Low T3 syndrome is a common complication in patients suffering from intracranial neurosurgical disorders and is associated with greater disease severity, complicated clinical course, and greater mortality and handicap rates. However, it remains unclear if low T3 syndrome can impact the findings of currently available clinical prognostic models and if management of low T3 syndrome can improve outcomes in neurosurgical patients.
