Extensive bone and soft tissue defects of the skull require unique plastic and reconstructive techniques to avoid and optimize aesthetic appearance following oncological resections. Procedures are ideally planned in an interdisciplinary board composed of neurosurgery, otorhinolaryngology, plastic and reconstructive surgery to facilitate reconstructive procedures of soft tissue and bone as early as possible in one approach. Large resections may require plastic surgery involvement from the beginning. Herein, we describe the function of a multidisciplinary approach to complex oncologic resections of the cranial base, scalp, and facial regions for neuro-oncologic patients...

Dilan A Patel, Jian L Campian
Malignant epidural spinal cord compression (MESCC) is an oncologic emergency with the potential for devastating consequences for patients if not promptly diagnosed and treated. MESCC is diagnosed by imaging. MRI is by far the most sensitive test, preferably with gadolinium. Once the diagnosis of MESCC is suspected, patients with neurologic deficits should receive prompt administration of dexamethasone with a 10-mg IV loading dose followed by 4 mg every 6 h. Quick taper is recommended once the definitive treatment is established...

BACKGROUND: Skull base lesions are not uncommon, but their management has been challenging for surgeons. There is large no of bony tumors at the skull base which has not been studied in detail as a group. These tumors are difficult not only because of their location but also due to their variability in the involvement of important local structure. Through this retrospective analysis from a Tertiary Care Centre, we are summarizing the details of skull base bony lesions and its management nuances...

BACKGROUND: Chronic subdural hematoma (CSDH) is a common indication for undergoing neurosurgery, but the outcome may remain limited despite timely surgical treatment. The factors potentially associated with the functional outcome have not been sufficiently investigated. We set out to identify independent predictors associated with the functional outcome after surgical treatment of CSDH, avoiding arbitrary classifications and thresholds or subjective imaging assessment. METHODS: We retrospectively reviewed 197 consecutive surgical cases of CSDH...

Incidence of vertebral compression fractures (VCFs) is increasing due to the increase in human life expectancy and prevalence of osteoporosis. Percutaneous vertebroplasty (PVP) has become a widely used alternative treatment for symptomatic VCFs refractory to medical therapy. It is a minimally invasive technique involving injection most frequently of polymethylmethacrylate (PMMA) directly into the vertebral body through the pedicles. Percutaneous vertebroplasty yields good results in terms of early vertebral stabilization and prompt pain relief...

BACKGROUND CONTEXT: Despite recent advances in gender equity in medicine, the representation of women in orthopaedic and neurosurgery remains particularly low. Furthermore compared to their male colleagues female faculty members are less likely to publish research, limiting opportunities in the academic promotion process. Understanding disparities in research productivity provides insight into the "gender gap" in the spine surgeon workforce. PURPOSE: To determine the representation and longevity of female physician-investigators among the authors of five spine-related research journals from 1978 to 2016...

Neurosurgery is experiencing the emergence of a new subspecialty focused on function restoration. New, evolving, and reappraised surgical procedures have provided an opportunity to restore function to many patients with previously undertreated disorders. Candidates for reconstruction were previously limited to those with peripheral nerve and brachial plexus injuries, but this has been expanded to include stroke, spinal cord injury, and a host of other paralyzing disorders affecting both upper and lower motor neurons...

Image-guided approaches to spinal instrumentation and interbody fusion have been widely popularized in the last decade [1-5]. Navigated pedicle screws are significantly less likely to breach [2, 3, 5, 6]. Navigation otherwise remains a point reference tool because the projection is off-axis to the surgeon's inline loupe or microscope view. The Synaptive robotic brightmatter drive videoexoscope monitor system represents a new paradigm for off-axis high-definition (HD) surgical visualization. It has many advantages over the traditional microscope and loupes, which have already been demonstrated in a cadaveric study [7]...
