Surgical access to the petroclival region poses a challenge to neurosurgeons. A wide range of approaches has been demonstrated in the past. In this video, the authors present a 69-year-old male patient who presented with 3-month history of worsening left-sided numbness. The tumor was totally removed in 2 sessions via anterior transpetrosal and retrosigmoid approaches, respectively. The authors demonstrate 2 separate skull base approaches to resect a petroclival meningioma and discuss pitfalls and problems of management for challenging meningiomas. The authors suggest that surgical approaches to petroclival meningiomas should be selected based on an individual case. A skull base team should be versatile in performing all these approaches.The video can be found here: https://youtu.be/BCVrn3TeNvE.

Abstract Objective: We examined the surgical approaches used at a single institution to treat petroclival meningioma and evaluated changes in method utilization over time. Methods: Craniotomies performed to treat petroclival meningioma between September of 1994 and July of 2005 were examined retrospectively. We reviewed 46 patients (mean follow-up, 3.6 yr). Techniques included combined petrosal or transcochlear approaches (15% of patients), retrosigmoid craniotomies with or without some degree of petrosectomy (59% of patients), orbitozygomatic craniotomies (7% of patients), and combined orbitozygomatic-retrosigmoid approaches (19% of patients). In 18 patients, the tumor extended supratentorially. Overall, the rate of gross total resection was 43%. Seven patients demonstrated progression over a mean of 5.9 years. No patients died. At 36 months, the progression-free survival rate for patients treated without petrosal approaches was 96%. Of 14 patients treated with stereotactic radiosurgery, none developed progression. Conclusion: Over the study period, a diminishing proportion of patients with petroclival meningioma were treated using petrosal approaches. Utilization of the orbitozygomatic and retrosigmoid approaches alone or in combination provided a viable alternative to petrosal approaches for treatment of petroclival meningioma. Regardless of approach, progression-free survival rates were excellent over short-term follow-up period.

Petroclival Meningiomas

Introduction: Petroclival meningiomas constitute 3 to 10% of meningiomas of the posterior fossa, they originate in the petroclival fissure, in the upper part of the clivus, petrosal apex, and medial to the trigeminal nerve. Resection of these tumors is a neurosurgical challenge. The combined partial petrosectomy approach associated with a sub-temporal approach is a technique described by various authors; however, its performance is considered highly complex. We report the case of a petroclival meningioma operated successfully in our hospital using a combined presigmoid and subtemporal transtentorial transpetrosal approach. Clinical case: 33-year-old female patient with a clinical picture of headache, nausea, and gait disturbance. Brain magnetic resonance imaging showed a large right petroclival tumor (4.2x3.9x3.8cm) that displaced the brainstem and secondary hydrocephalus. The hydrocephalus was treated with a ventricular peritoneal shunt. Then, the tumor was resected using a combined presigmoid and subtemporal transpetrosal approach, a technique that allowed adequate exposure of the tumor, achieving complete resection, without intraoperative complications. Postoperative evolution was favorable, with no sequelae. Conclusion: The combined presigmoid and transtentorial subtemporal transpetrous approach for petroclival meningiomas is an effective and feasible technique to perform in our environment. The support of technology such as Neuronavigation, the ultrasonic aspirator, intraoperative monitoring, and adequate experience in skull base surgery are fundamental factors for the success of this surgery.

AbstractTraumatic injuries to the skull base can involve critical neurovascular structures and present with symptoms and signs that must be recognized by physicians tasked with management of trauma patients. This article provides a review of skull base anatomy and outlines demographic features in skull base trauma. The manifestations of various skull base injuries, including CSF leaks, facial paralysis, anosmia, and cranial nerve injury, are discussed, as are appropriate diagnostic and radiographic testing in patients with such injuries. While conservative management is sometimes appropriate in skull base trauma, surgical access to the skull base for reconstruction of traumatic injuries may be required. A variety of specific surgical approaches to the anterior cranial fossa are discussed, including the classic anterior craniofacial approach as well as less invasive and newer endoscope-assisted approaches to the traumatized skull base.

Free will is a perennial issue in philosophy, both in terms of the history of philosophy and in contemporary discussions. Aspects of free will relate to a wide range of philosophical issues, but especially to metaphysics and ethics. For roughly the past three decades, the literatures on free will and moral responsibility have overlapped to such a degree that it is impossible to separate them. This entry focuses on contemporary discussions about the nature and existence of free will, as well as its relationship to work in the sciences and philosophy of religion.

Star Wars has reached more than three generations of casual and hardcore fans alike, and as a result many of the producers of franchised Star Wars texts (films, television, comics, novels, games, and more) over the past four decades have been fans-turned-creators. Yet despite its dominant cultural and industrial positions, Star Wars has rarely been the topic of sustained critical work. Star Wars and the History of Transmedia Storytelling offers a corrective to this oversight by curating essays from a wide range of interdisciplinary scholars in order to bring Star Wars and its transmedia narratives more fully into the fold of media and cultural studies. The collection places Star Wars at the center of those studies’ projects by examining video games, novels and novelizations, comics, advertising practices, television shows, franchising models, aesthetic and economic decisions, fandom and cultural responses, and other aspects of Star Wars and its world-building in their multiple contexts of production, distribution, and reception. In emphasizing that Star Wars is both a media franchise and a transmedia storyworld, Star Wars and the History of Transmedia Storytelling demonstrates the ways in which transmedia storytelling and the industrial logic of media franchising have developed in concert over the past four decades, as multinational corporations have become the central means for subsidizing, profiting from, and selling modes of immersive storyworlds to global audiences. By taking this dual approach, the book focuses on the interconnected nature of corporate production, fan consumption, and transmedia world-building. As such, this collection grapples with the historical, cultural, aesthetic, and political-economic implications of the relationship between media franchising and transmedia storytelling as they are seen at work in the world’s most profitable transmedia franchise.

Ancient Times

Hysterectomy, which is one of the most common surgeries performed on women, dates back to ancient times. The history of hysterectomy comprises biographies of many humble men and the significant individual efforts that they made to fight the skepticism of the medical communities of their times. Many of the pioneers were ignored. Although there are a number of alternatives to hysterectomy available, it remains one of the most frequently performed gynaecological operations. The introduction of antisepsis, anaesthesia, antibiotics and blood transfusion made hysterectomy a safe procedure. Nowadays, we distinguish three different surgical approaches to hysterectomy: vaginal, abdominal and laparoscopic. The limitations of conventional laparoscopy have led to the development of robotic surgery, which has evolved over the past decade from simple adjustable arms to support cameras in laparoscopic surgery to more sophisticated four-armed machines now being in use worldwide.

This handbook takes on the task of examining the history of music listening over the past two hundred years. It uses the “art of listening” as a leitmotif encompassing an entanglement of interdependent practices and discourses about a learnable mode of perception. The art of listening first emerged around 1800 and was adopted and adapted across the public realm to suit a wide range of collective listening situations from popular to serious art forms up to the present day. Because this is a relatively new subject in historical research, the volume combines case studies from several disciplines in order to investigate whether, how, and why practices of music listening changed. Focusing on a diverse set of locations and actors and using a range of historical sources, it attempts to historicize and reconstruct the evolution of listening styles to show the wealth of variants in listening. In doing so, it challenges the inherited image of the silent listener as the dominant force in musical cultures.

Formidable Challenge

Object Petroclival meningiomas remain a formidable challenge for neurosurgeons because of their location deep within the skull base and proximity to eloquent neurovascular structures. Various skull base approaches have been used in their treatment, and deciding which is the optimal one remains controversial. Attempts at achieving gross- or near-total resections are associated with an increased rate of morbidity and mortality. As adjunctive treatment options such as stereotactic radiosurgery have been developed and become widely available, there has been a trend toward accepting subtotal resections in an effort to minimize neurological morbidity. This paper reviews a recent series of patients with petroclival meningiomas and highlights current management trends and important considerations useful in surgical decision making. Methods The records of patients with large (> 3 cm) petroclival meningiomas surgically treated by the senior author over the past 5 years were reviewed. The clinical results are presented as examples of the surgical approaches available for approaching these tumors, and treatment options are reviewed. Results Of 196 meningiomas surgically treated during the study period, 8 lesions in 8 patients met the study criteria. Overall clinical results were excellent, with no death or major morbidity. Intracranial gross- or near-total resection (Simpson Grade 1, 2, or 3) was achieved in 5 patients (67%). New cranial nerve deficits occurred in 3 patients (37%) and were more common in patients in whom a subtotal resection was performed (2 of 3 cases). A variety of surgical approaches were used. Important considerations determining the best approach include the location of the tumor relative to the internal auditory canal, the presence of preoperative hearing loss, and the location of the tumor relative to the tentorium. Conclusions Achieving gross- or near-total resections of large petroclival meningiomas remains achievable and should be the primary goal of surgical treatment. A retrosigmoid craniotomy remains a workhorse surgical approach for most petroclival tumors of any size. Tumors that are medial to the internal auditory canal and span both middle and posterior cranial fossae are often best treated with a combined transpetrosal approach, which is especially true if there is a preoperative hearing deficit.
