Oral and general health quality of life following a subtemporal preauricular infratemporal approach with condylar fossa osteotomy in surgical skull base tumor resection.
With the capacity to provide maximal lesion exposure, the subtemporal preauricular infratemporal (SPI) approach with condylar fossa osteotomy is highly utilized in radical resection of skull base tumors. While this approach requires disruption of the temporomandibular joint (TMJ) for access, the effects of this maneuver are poorly appreciated in neurosurgery. The aim of this study was to assess the morbidity of condylar fossa osteotomies by comparing oral health quality of life (OHQOL) and general health quality of life (GHQOL) outcomes after TMJ-involving and TMJ-sparing skull base approaches. ⋯ The authors report novel findings regarding the impact of the SPI approach with a condylar fossa osteotomy on OHQOL and GHQOL among skull base tumor patients. Anatomical disruption of the TMJ was not associated with significant clinical TMJ dysfunction. Compared with TS patients, CS patients had even lower mean scores in TMJ-related morbidity, and both groups had lower TMJ morbidity than patients diagnosed with chronic TMJ dysfunction. Condylar fossa osteotomies can therefore be considered without concern of significant additional morbidity.

Wartime penetrating traumatic brain injury of the anterior skull base involving the paranasal sinuses: a single-center, first-year experience from Dnipro, Ukraine.
Since February 2022, the number of casualties in the Russian-Ukrainian war have dramatically increased, with a high incidence of penetrating traumatic brain injuries (pTBIs). To date, there has been limited evaluation of pTBI of the anterior skull base involving the paranasal sinuses. The objective of this study was to highlight the authors' experience with this injury pattern and identify specific factors associated with favorable short-term (1-month) outcome and survival. ⋯ This was the largest single-year study on neurosurgical treatment of wartime pTBI involving the paranasal sinuses. Implementation of primary neurosurgical intervention at the time of presentation demonstrated promising early results and a shift away from expectant management of this injury pattern. The association of high admission GCS score, low ISS, favorable injury lateralization, and no midline shift on favorable short-term outcomes or survival has not been previously documented with this injury pattern.

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.
