“…The actual impact of imaging on clinical decision-making still needs to be validated, but the ability to improve image quality without additional radiation exposure, and even reducing radiation, represents a significant breakthrough in detector development. The enhanced precision achieved through multiplanar reconstruction and VRT reconstruction techniques in this study demonstrates substantial potential for achieving precise diagnostic accuracy and optimizing surgical access [ 33 , 34 ]. Furthermore, this advancement may influence the educational processes of future medical professionals [ 35 ].…”

Detailed visualization of the cribriform plate is challenging due to its intricate structure. This study investigates how computed tomography (CT) with a novel photon counting (PC) detector enhance cribriform plate visualization compared to traditionally used energy-integrated detectors in patients. A total of 40 patients were included in a retrospective analysis, with half of them undergoing PC CT (Naeotom Alpha Siemens Healthineers, Forchheim, Germany) and the other half undergoing CT scans using an energy-integrated detector (Somatom Sensation 64, Siemens, Forchheim, Germany) in which the cribriform plate was visualized with a temporal bone protocol. Both groups of scans were evaluated for signal-to-noise ratio, radiation dose, the imaging quality of the whole scan overall, and, separately, the cribriform plate and the clarity of volume rendering reconstructions. Two independent observers conducted a qualitative analysis using a Likert scale. The results consistently demonstrated excellent imaging of the cribriform plate with the PC CT scanner, surpassing traditional technology. The visualization provided by PC CT allowed for precise anatomical assessment of the cribriform plate on multiplanar reconstructions and volume rendering imaging with reduced radiation dose (by approximately 50% per slice) and higher signal-to-noise ratio (by approximately 75%). In conclusion, photon-counting technology provides the possibility of better imaging of the cribriform plate in adult patients. This enhanced imaging could be utilized in skull base-associated pathologies, such as cerebrospinal fluid leaks, to visualize them more reliably for precise treatment.

“…Olfactory nerve injuries during neurosurgical approaches are a well-known risk. 3 4 Retraction of the frontal lobe can cause direct damage of the olfactory nerve, disruption of the fila olfactoria, or vascular injury. Yasargil 9 emphasized the importance of understanding the vascular supply of the olfactory nerve during the pterional approach.…”

“…In case of pathologic lesions such as olfactory groove or sphenoidal plane meningiomas, preservation of the intact olfaction should be an important aspect. 3 4 To approach these lesions, the above-described cranial openings and the endonasal route, which is not analyzed in the present study, should be carefully considered by the operating surgeon for the best-fitting therapy. Our study about the outer arachnoid cover of the olfactory bulb as the main structure transmitting retraction forces provides an important anatomical base for this challenging clinical problem.…”

Background: Surgical approaches to the anterior cranial fossa have great risk of damaging the olfactory tract and bulb. The goal of this study was to describe the outer arachnoid envelope around the olfactory bulb which plays significant role in the approach-related injury of the nerve. Material and Methods: A total of 20 fresh human cadaveric heads were examined as a following: 5 cadaveric heads were used to describe a gross overview of the topographic anatomy of the outer arachnoid cover of the olfactory bulb. In 15 cadaveric heads endoscopic surgical approaches were performed to examine the in situ undisrupted anatomy of the outer arachnoid around the olfactory bulb. Four cadaveric heads were used for lateral subfrontal approach, 5 heads for medial subfrontal, 3 heads for median subfrontal approach and 3 heads for anterior interhemispheric approach. Results: The outer arachnoid membrane of the frontal lobe attaches the olfactory bulb strongly to the above lying olfactory sulcus. Only the most rostral portion of the olfactory bulb became slightly detached from the frontal lobe. The outer arachnoid forms a decent protrusion around the tip of the olfactory bulbs. The fila olfactoria have their own outer arachnoid cover as a continuation of the same layer of the olfactory bulb. The effect of brain retraction and manipulation forces on the olfactory bulb and the role of the here located arachnoid membranes were visually analysed and described in detail through the performed four different neurosurgical approaches. Conclusion: The results of our observations provide important anatomical details for the preservation of smelling during neurosurgical procedures.
