Microsurgical anatomy and the inner architecture of the retrocommissural portion of the hippocampal formation demonstrated through fiber microdissection.
An understanding of the complex nomenclature and 3D spatial relations between the cortical and white matter components of the retrocommissural portion of the hippocampal formation is essential for a successful outcome when performing surgery in the mediobasal temporal region. The goal of this study was to clarify the nomenclature related to the retrocommissural portion of the hippocampal formation and to provide a detailed description of its topography and inner structure from a relevant surgical perspective. This description can serve as an anatomical reference for approaching lesions in the mediobasal temporal region. ⋯ The fiber microdissection technique provides a valuable perspective for understanding the complex structure and relations of the components of the retrocommissural portion of the hippocampal formation. This study clarifies and supplements the information presently available in the literature by offering an anatomical reference essential for differentiating the topographic diagnosis and safer surgical planning for any lesion within this formation or the mediobasal temporal region.

Physicians generally underestimate their potential to influence social progress, despite substantial precedents for medical professionals leading important societal transformations. The author believes that our times require we challenge the notion that physicians have limited influence beyond clinical settings. Our voice is powerful and important. ⋯ All contributors were invited to weave their insights regarding what truly matters into a broad, thought-provoking intellectual and spiritual tapestry. Universally resonant themes such as empathy, innovation, resilience, leadership, value, trust and equity framed the cooperative dialogues, emphasizing our shared humanity and the core values uniting us-despite our differences. The objectives for the 2024 Annual Meeting were ambitious: to consider as a professional community themes of utmost importance to our professional and personal lives; to catalyze a profound reevaluation of our collective objectives; to envision an expanded common mission; and to inspire visionary leaders to collaborate on creating lasting value-both for the patients who are the principal focus of our shared devotion, and for society writ large.

Conservative management of brain arteriovenous malformations: results of the prospective observation registry of a pragmatic trial.
Many patients recruited in the Treatment of Brain Arteriovenous Malformations Study (TOBAS) are managed conservatively. The aim of this study was to monitor what happened to those patients. ⋯ Nearly half of TOBAS participants were observed. Rates of untoward neurological events were within expected boundaries.

Visual deterioration secondary to medial sphenoid wing meningioma: systematic assessment of patient-reported outcomes and factors contributing to recovery after surgical treatment.
Visual acuity (VA) constitutes an important outcome measure in surgery for medial sphenoid wing meningioma (SWM). This study aimed to assess the recovery of tumor-associated impairment of VA and its impact on patient-reported outcome measures (PROMs) as an indication of vision-related quality of life in patients who had undergone surgery for medial SWM. ⋯ The overall preoperative duration of tumor-related visual impairment significantly correlates to the extent of postoperative visual improvement as well as vision-related PROMs in medial SWM surgery. These results might aid in preoperative patient counseling and help optimize decision-making and preoperative estimation of long-term visual outcome.

Extended transcavernous posterior clinoidectomy in endoscopic endonasal surgery.
Mastery of the posterior clinoidectomy technique is of utmost importance for neurosurgeons who specialize in endoscopic endonasal approaches, because the posterior clinoid process (PCP) is commonly involved in chondroid tumor resection. Three main techniques for posterior clinoidectomy have been developed: intradural, extradural, and transcavernous interdural. The authors introduce here a novel technical variant in which the transcavernous approach is extended to the dorsal clinoidal space after transection of the caroticoclinoid ligament, and they elaborate on its clinical application on the basis of anatomical dissections and radiological studies. ⋯ This report details the extended transcavernous posterior clinoidectomy as a novel technical variant for achieving maximal exposure of the PCP in endoscopic endonasal surgery. In addition, the positive results establish the importance of preoperative skull base imaging for surgical planning.
