Purpose: This study aimed to verify the feasibility, safety, and benefit of using fluorescein sodium (FL) and a YELLOW 560 nm filter in posterior fossa tumors in children.
Methods: All cases of pediatric posterior fossa tumors that have undergone surgery using fluorescein (2018-2022) have been included and were examined retrospectively. In those cases where resection of the tumor was planned, a blinded neuroradiologist distinguished gross total resection and subtotal resection according to the postoperative MRI findings. The surgical report and medical files were reviewed regarding the intraoperative staining grade and adverse events. The grade of fluorescent staining of the targeted lesion was assessed as described in the surgical reports. The screening was conducted for any reference to the degree of fluorescent staining: "intense," "medium," "slight," and "no staining."
Results: 19 cases have been included. In 14 cases, a complete resection was initially intended. In 11 of these cases, a gross total resection could be achieved (78.6%). Staining was described as intense in most cases (58.8%). Except for yellow-colored urine, no side effects obviously related to FL were found throughout the observation period.
Conclusion: In combination with a specific filter, FL is a reliable, safe, and feasible tool in posterior fossa surgery in children.

K-Wire-Assisted Intra-axial Intradural Approach for Cavernous Sinus Biopsy: A Case Report.

Neurosurgery, University of Illinois College of Medicine Peoria, Peoria, USA.
Petroclival approaches remain challenging given abundant cranial nerves and vessels. Common trajectories include transsphenoidal, transoral, middle fossa-extradural, and posterior through the cerebellar peduncle. We report a unique intra-axial, intradural approach to the petroclival and cavernous sinus.

Trigeminal neuralgia (TN) is most commonly caused by vascular compression at the trigeminal nerve root entry zone. Secondary TN caused by cranial FD syndrome is extremely rare.

Objective: To evaluate the efficacy of pedicled supraclavicular flaps in hypopharyngectomy reconstruction, with a focus on preserving laryngeal function.
Methods: From August 2019 to June 2022, 14 patients with primary hypopharyngeal carcinoma who met the inclusion and exclusion criteria and underwent the repair of hypopharyngeal defects using pedicled supraclavicular flaps were included retrospectively. Relevant clinical evaluation indicators include patient characteristics, defect sizes, flap sizes, flap harvesting time, postoperative hospital stay, postoperative complications, recurrence, and survival outcomes.

Introduction: We investigated whether the cerebellum develops neuropathology that correlates with well-accepted Alzheimer's disease (AD) neuropathological markers and cognitive status.
Methods: We studied cerebellar cytoarchitecture in a cohort (N = 30) of brain donors. In a larger cohort (N = 605), we queried whether the weight of the contents of the posterior fossa (PF), which contains primarily cerebellum, correlated with dementia status.
Morphometric Analysis of the Greater Palatine Foramina in the Bosnia and Herzegovina Population.

Department of Anatomy, Medical Faculty, University in Sarajevo, Čekaluša 90, 71 000 Sarajevo, Bosnia and Herzegovina.
Objective: The goal of this research was to examine the morphological characteristics and exact anatomical positioning of the greater palatine foramen (GPF), with reference to nearby anatomical landmarks.
Material And Method: The research was performed on dry human skulls belonging to the Bosnian and Herzegovina population, using digital vernier calipers. The study began by noting the GPF's position relative to the maxillary molars, then measuring its distance from the median palatine suture (MPS), the incisive fossa (IF), the posterior border of the hard palate (PBHP), and the posterior nasal spine (PNS).
