    Abstract Introduction: This paper was presented at the International Society for Pediatric Neurosurgery Meeting in Cape Town in October 2008 during the post-meeting Focus Session on Intraoperative Neurophysiology.
    Discussion: It reflects the personal views of the author and is intended as a pragmatic approach to cases where a non-invasive pre-surgical evaluation has not been successful in localising the epileptogenic zone. It is based on the experience of the multi-disciplinary team at Great Ormond Street Hospital without whose support none of the surgical work would be possible.

    Abstract Introduction: In the 50 years since Penfield outlined the requirements of the epilepsy surgeon, we have seen the introduction of the digitised electroencephalogram (EEG), video telemetry and the magnetic resonance imaging (MRI) scan. In the operating room, advances in neuro-anaesthesia, the introduction of the operating microscope, image guidance and the ultrasonic aspirator have greatly enhanced the surgeons' technical ability. Despite these changes, the thesis encapsulated in Penfield's statement is that the surgeon needs to understand and interpret the preoperative data in such a way as to identify as closely as possible the epileptogenic zone where he must carry out surgery with the utmost care and diligence, and finally, in the context of audit and follow-up of his surgical patients, he must be able to predict for each individual case the likelihood of success and failure of any particular procedure.
    Conclusion: Previous articles in this supplement have looked at the specific investigations carried out to identify the epileptogenic zone, but once this data has been gathered, it is the responsibility of the neurosurgeon, within the context of the multidisciplinary team, to decide whether surgery is both feasible and advisable and then to discuss this in depth with the patient and their family and carers. The multidisciplinary epilepsy surgery meeting allows cases to be discussed in an open forum and the decisions made in this meeting can then be discussed with the family. The process of consent will begin from the moment any surgical procedure is discussed and should, wherever possible, be reinforced with written, as well as verbal, information. The process of consent should be a continuum until the actual day of surgery. All parties involved in the care and management of the patient should be regarded as stakeholders in this decision, and it is vital that all these stakeholders are working towards a common goal.
    Objectives: In this article, I will consider the specific aspects of the presurgical investigations that are applicable to the temporal lobe and the differing types of surgery that are likely to be indicated. I will then describe, in detail, the surgical technique of temporal lobe resection, highlighting some of the pitfalls and successes that such surgery can provide.

    Abstract Objective: To evaluate the presence, extent, and temporality of transnational neurosurgical partnerships, to understand and inform measures to address neurosurgical deficiencies in low- and middle-income countries (LMICs).
    Methods: A Web search was conducted to identify actors from high-income countries (HICs) participating in neurosurgical delivery and/or capacity-building with LMICs from 2010 to 2018. Descriptive data on current neurosurgical partnerships were collected from published case reports, literature reviews, reports from academic institutions, and information on stakeholder Web pages. The level of training and engagement of each partnership was separately graded based on prespecified criteria, in which grade 3 represented partnerships that have most extensive training and engagement, and grade 1, the least extent. Data were analyzed using descriptive statistics and geospatially depicted on ArcMap GIS software.
    Results: A total of 123 unique HIC-LMIC partnerships were described. Of these partnerships, 85 (69%) are derived from HICs in North America, followed by Europe, with 23 (19%). The most common LMIC partners were from Africa (n = 56, 45%) and Latin America (n = 32, 26%). In addition, most partnerships provided services in pediatric neurosurgery (88%). The most frequent engagement classifications were grade 2 (35%) or 1 (36%). Similarly, for training, the most common classifications were grade 1 (40%) or 2 (30%).
    Conclusions: A robust network of HIC-LMIC partnerships exists with varying degrees of engagement and training activities. Several regions are particularly suitable for growth and development. Systematic consolidation and indexing of transnational neurosurgical partnerships aim to enhance resource allocation and present opportunities for future partnership.

    Abstract Objective: Despite general enthusiasm for international collaboration within the organized neurosurgical community, establishing international partnerships remains challenging. The current study analyzes the initial experience of the InterSurgeon website in partnering surgeons from across the world to increase surgical collaboration.
    Methods: One year after the launch of the InterSurgeon website, data were collected to quantify the number of website visits, average session duration, total numbers of matches, and number of offers and requests added to the website each month. Additionally, a 15-question survey was designed and distributed to all registered members of the website.
    Results: There are currently 321 surgeon and institutional members of InterSurgeon representing 69 different countries and all global regions. At the time of the survey there were 277 members, of whom 76 responded to the survey, yielding a response rate of 27.4% (76/277). Twenty-five participants (32.9%) confirmed having either received a match email (12/76, 15.8%) or initiated contact with another user via the website (13/76, 17.1%). As expected, the majority of the collaborations were either between a high-income country (HIC) and a low-income country (LIC) (5/18, 27.8%) or between an HIC and a middle-income country (MIC) (9/18, 50%). Interestingly, there were 2 MIC-to-MIC collaborations (2/18, 11.1%) as well as 1 MIC-to-LIC (1/18, 5.6%) and 1 LIC-to-LIC partnership. At the time of response, 6 (33.3%) of the matches had at least resulted in initial contact via email or telephone. One of the partnerships had involved face-to-face interaction via video conference. A total of 4 respondents had traveled internationally to visit their partner's institution.
    Conclusions: Within its first year of launch, the InterSurgeon membership has grown significantly. The partnerships that have already been formed involve not only international visits between HICs and low- to middle-income countries (LMICs), but also telecollaboration and inter-LMIC connections that allow for greater exchange of knowledge and expertise. As membership and site features grow to include other surgical and anesthesia specialties, membership growth and utilization is expected to increase rapidly over time according to social network dynamics.

    Abstract Objective: The presence and capability of existing pediatric neurosurgical care worldwide is unknown. The objective of this study was to solicit the expertise of specialists to quantify the geographic representation of pediatric neurosurgeons, access to specialist care, and equipment and training needs globally.
    Methods: A mixed-question survey was sent to surgeon members of several international neurosurgical and general pediatric surgical societies via a web-based platform. Respondents answered questions on 5 categories: surgeon demographics and training, hospital and practice details, surgical workforce and access to neurosurgical care, training and equipment needs, and desire for international collaboration. Responses were anonymized and analyzed using Stata software.
    Results: A total of 459 surgeons from 76 countries responded. Pediatric neurosurgeons in high-income and upper-middle-income countries underwent formal pediatric training at a greater rate than surgeons in low- and lower-middle-income countries (89.5% vs 54.4%). There are an estimated 2297 pediatric neurosurgeons in practice globally, with 85.6% operating in high-income and upper-middle-income countries. In low- and lower-middle-income countries, roughly 330 pediatric neurosurgeons care for a total child population of 1.2 billion. In low-income countries in Africa, the density of pediatric neurosurgeons is roughly 1 per 30 million children. A higher proportion of patients in low- and lower-middle-income countries must travel > 2 hours to seek emergency neurosurgical care, relative to high-income countries (75.6% vs 33.6%, p < 0.001). Vast basic and essential training and equipment needs exist, particularly low- and lower-middle-income countries within Africa, South America, the Eastern Mediterranean, and South-East Asia. Eighty-nine percent of respondents demonstrated an interest in international collaboration for the purposes of pediatric neurosurgical capacity building.
    Conclusions: Wide disparity in the access to pediatric neurosurgical care exists globally. In low- and lower-middle-income countries, wherein there exists the greatest burden of pediatric neurosurgical disease, there is a grossly insufficient presence of capable providers and equipped facilities. Neurosurgeons across income groups and geographic regions share a desire for collaboration and partnership.
