Parasellar region meningiomas with optic canal (OC) invasion: Correlation between the degree of decompression of the OC and the improvement of visual acuity.

Purpose: To evaluate the correlation between the degrees of circumferential decompression of the optic canal (OC) and the improvement of visual acuity in patients with parasellar meningiomas (PMs) with optic canal invasion.

Methods: This is a monocentric retrospective study conducted at author's institution. The visual acuity was evaluated preoperative and at 3-months after surgery with Snellen acuity test.

Anatomical Differences in Sphenoid Sinus During Endoscopic Transsphenoidal Surgery: Comparison Between Nonfunctioning Pituitary Neuroendocrine Tumor (PiTNET) and Growth Hormone-Secreting PiTNET.

Background: In surgical practice during endoscopic endonasal approach, growth hormone-secreting pituitary neuroendocrine tumor (GH-secreting PitNET) patients show morphologic differences in the nasal cavities and sinuses, leading to a narrower surgical field and a carotid prominence and potentially increasing the complexity of the surgical and the risk of complications. The aim of the study is to evaluate the anatomical differences of the sphenoid sinus between patients with GH-secreting PitNETs and patients with nonfunctioning pituitary neuroendocrine tumor (NF-PitNET) who underwent endoscopic endonasal approach.

Methods: This is a monocentric retrospective study conducted at the author's institution.

Early versus delayed mobilization after aneurysmal subarachnoid hemorrhage: a systematic review and meta-analysis of efficacy and safety.

Objective: A central tenet of Enhanced Recovery After Surgery (ERAS) is evidence-based medicine. Survivors of aneurysmal subarachnoid hemorrhage (aSAH) constitute a fragile patient population prone to prolonged hospitalization within neurointensive care units (NICUs), prolonged immobilization, and a range of nosocomial adverse events. Potentially, well-monitored early mobilization (EM) could constitute a beneficial element of ERAS protocols in this population.

Introducing endoscopic assistance on routinary basis for vestibular schwannomas resection: A single centre acceptance analysis.

Objective: The use of endoscopic assistance in retrosigmoid approach for tumors of the cerebellopontine angle brought undoubted technological advantages in skull base surgery. Nonetheless, the use of the endoscope is not as widespread as it could be. The aim of the study is to analyze the impressions of neurosurgeons and otologists with different experience in vestibular schwannoma surgery, experiencing the introduction of the endoscope in surgical daily practice.

Lesson learned in endoscopic endonasal dens resection for C1-C2 spinal cord decompression.

Purpose: Endoscopic endonasal approach (EEA) is the safest and most effective technique for odontoidectomy. Nevertheless, this kind of approach is yet not largely widespread. The aim of this study is to share with the scientific community some tips and tricks with our ten-year-old learned experience in endoscopic endonasal odontoidectomy (EEO), which remains a challenging surgical approach.

Facial nerve outcome score: a new score to predict long-term facial nerve function after vestibular schwannoma surgery.

Introduction: Patients' quality of life (QoL), facial nerve (FN), and cochlear nerve (CN) (if conserved) functions should be pursued as final outcomes of vestibular schwannoma (VS) surgery. In regard to FN function, different morphologic and neurophysiological factors have been related to postoperative outcomes. The aim of the current retrospective study was to investigate the impact of these factors on the short- and long-term FN function after VS resection.

Hardware-Related Skin Erosion in Deep Brain Stimulation for Parkinson's Disease: How Far Can We Go? An Illustrative Case Report.

Skin erosion is a hardware-related complication commonly described after deep brain stimulation (DBS). Hardware exposure is often associated with the development of infection that can lead to implant removal. However, in selected cases, it is possible to manage skin erosion without having to remove the hardware.

Lymphoplasmacyte-rich meningioma with hematologic signs and PD-L1 over-expression.

Lymphoplasmacyte-rich meningioma (LPRM) is one of the rarest variants of grade I meningiomas. It can be clinically associated with prominent peripheral blood abnormalities, anemia, and/or various gammopathy, which usually disappear after surgical removal of the tumor. We document a case of right frontal LPRM in a 72-year-old male who presented general cognitive decadence.

Peculiar bony involvement of sinus pericranii in children: Extensive diploic erosion in three "karstic" variants.

Object: Sinus pericranii (SP) is a rare, benign, extradural venous anomaly whose extracranial connection consists in an enlarged subgaleal drainage composed of a network of thin-walled veins that form a varix on the external table of the skull. In the present series of three patients we present three variantesof SP which have never been described, characterized by an extensive diploic erosion causing a "karstic" effect.

Methods: A systematic review was conducted in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline.

The Boundless World of Cranioplasty: A Multicenter Retrospective Study and Therapeutic Flow-Chart Patient-Specific Based.

Background: Cranioplasty is both a functional and aesthetical therapeutic option. In the clinical scenario every cranioplasty's material is potentially qualified to achieve the goal of calvarian reconstruction but there is a lack of agreement about the optimum choice, especially between the heterologous ones. The choice of cranioplasty widely depends on surgeon's personal preferences.

Surgical Back Risk Syndrome and Spinal Cord Stimulation: Better Safe Than Sorry.

Background: Recurrent and chronic low back pain, caused by degenerative lumbar spondylosis, commonly affects elderly patients, even those with no previous low back surgery. These patients, like those affected by failed back surgery syndrome (FBSS), may become unresponsive to medical conservative treatment and their quality of life could be easily compromised. Moreover, general comorbidities, obesity, and other typical conditions of the elderly may make surgery under general anesthesia riskier than the natural history of the disease.
