Ectopic primary olfactory neuroblastoma: Clinical management of an extremely rare entity

Oral Oncology Reports
Background: Olfactory neuroblastoma (ONB) is a rare malignant neoplasm of neuroectodermal origin. Within an already very rare neoplasm, an even rarer and lesser-known entity is ectopic ONB. Methods: A 57-year-old female patient was evaluated for a smooth

Magnetic resonance imaging of cerebrospinal fluid outflow after low-rate lateral ventricle infusion in mice

JCI Insight, 2022
The anatomical routes for the clearance of cerebrospinal fluid (CSF) remain incompletely understood. However, recent evidence has given strong support for routes leading to lymphatic vessels. A current debate centers upon the routes through which CSF can

Breathing‐Induced Airflow Measurements at Multiple Positions in a 3D‐Printed Nasal Cavity

Advanced Sensor Research, Volume 5, Issue 6, June 2026.
This study presents a novel experimental approach for measuring localized nasal airflow dynamics using person‐specific 3D‐printed models. By integrating miniature pressure differential sensors into precise anatomical replicas, we achieve site‐specific measurements that overcome the limitations of conventional rhinomanometry.

New Insights Into Cranial Base Ontogeny in Modern Humans Through Morphometric Analysis

American Journal of Biological Anthropology, Volume 190, Issue 2, June 2026.
ABSTRACT Objectives The cranial base is located at the interface between the face, the brain, and the vertebral column. Understanding its growth is essential for elucidating key aspects of craniofacial development, neurodevelopment, and locomotor function.

Cribriform plate of ethmoid, olfactory bulb and olfactory acuity in forty species of bats

, 1974
Relationships between the cribriform plate of the ethmoid, the olfactory bulb, and olfactory acuity were explored using material from 13 of the 17 bat families. All megachiropteran cribriform plates were entirely perforated. In contrast, microchiropteran

Ectopic Olfactory Neuroblastoma of the Maxillary Sinus: A Case Report

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Olfactory neuroblastoma is a rare neuroendocrine tumor typically arising from the superior nasal cavity, and primary occurrence in the maxillary sinus is exceptionally uncommon, often leading to diagnostic confusion with other sinonasal malignancies. A 34‐year‐old man presented with bilateral nasal obstruction, recurrent epistaxis, and frontal

Beyond Vasospasm: Dual Milrinone and Balloon Angioplasty in Refractory Delayed Cerebral Ischemia Post‐Subarachnoid Hemorrhage

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Cerebral vasospasm is a major complication of aneurysmal subarachnoid hemorrhage and a key contributor to delayed cerebral ischemia, which remains a leading cause of morbidity despite standard therapy with nimodipine and induced hypertension.

Combined Anterior Craniofacial Resection for Tumors Involving the Cribriform Plate: Early Postoperative Complications and Technical Considerations

, 2000
OBJECTIVE: Combined craniofacial resection has become the standard approach for malignant tumors involving the cribriform plate and anterior cranial fossa. Despite its widespread application, however, many surgeons agree that the procedure carries a risk

Intranasal Delivery of Bacterial Extracellular Vesicles Enables RNA Cargo Entry Into the Brain

Journal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.
ABSTRACT Extracellular vesicles (EVs) released by bacteria are potent mediators of host–microbe interactions. They modulate immune responses, deliver functional molecules and influence disease progression. However, whether bacterial EVs can access the brain and functionally affect host cells remains unclear.
