AI Article Synopsis

  • Skull base surgery has evolved significantly due to neuroanatomic research, which has enhanced techniques like the endoscopic endonasal and transorbital approaches.
  • The development of the endoscopic transorbital approach involves four conceptual steps: examining orbital anatomy on dry skulls, detailed bone studies, cadaver dissection, and 3D quantitative assessments.
  • This anatomical analysis indicates that these steps are interconnected and adaptable, promoting the understanding and application of new surgical techniques.

Article Abstract

Background: In the last decades, skull base surgery had passed through an impressive evolution. The role of neuroanatomic research has been uppermost, and it has played a central role in the development of novel techniques directed to the skull base. Indeed, the deep and comprehensive study of skull base anatomy has been one of the keys of success of the endoscopic endonasal approach to the skull base. In the same way, dedicated efforts expended in the anatomic lab has been a powerful force for the growth of the endoscopic transorbital approach to the lateral skull base.Therefore, in this conceptual paper, the main steps for the anatomic description of the endoscopic transorbital approach to the skull base have been detailed.

Methods: The anatomic journey for the development of the endoscopic transorbital approach to the skull base has been analyzed, and four "conceptual" steps have been highlighted.

Results: As neurosurgeons, the eyeball has always represented a respectful area: to become familiar with this complex and delicate anatomy, we started by examining the orbital anatomy on a dry skull (step 1). Hence, is represented by a detailed bone study; is centered on cadaveric dissection; consists in 3D quantitative assessment of the novel endoscopic transorbital corridor; and finally, is the translation of the preclinical data in the real surgical scenario by means of dedicated surgical planning.

Conclusions: The conceptual analysis of the anatomic journey for the description of the endoscopic transorbital approach to the skull base resulted in four main methodological steps that should not be thought strictly consequential but rather interconnected. Indeed, such steps should evolve following the drives that can arise in each specific situation. In conclusion, the anatomic rehearsal can be relevant for the description, diffusion, and development of a novel technique in order to facilitate the application of the endoscopic transorbital approach to the skull base in a real surgical scenario.

Chordomas are a low-to-intermediate-grade slow-growing subtype of sarcoma, but show propensity to grow and invade locally with recurrence and metastasis in 10-40% of cases. We describe the first case of spontaneous regression of a solid tumor (histologically and immunohistochemically proven chordoma) after COVID-19. A female patient with clival chordoma underwent occipitocervical fixation prior to tumor resection.

Hydrolethalus Syndrome: A Case of a Rare Congenital Disorder.

Diagnostics (Basel)

January 2025

Department of Dentistry, Faculty of Dentistry, "Vasile Goldiș" Western University of Arad, 94-96 Revolutiei Blvd., 310025 Arad, Romania.

This is a fatal case of multiple complicated congenital anomalies displaying several symptoms consistent with hydrolethalus syndrome. The newborn's phenotype is characterized by a combination of serious anatomical abnormalities such as open-book cerebral hemispheres, defective lobulation of the lungs (one lobe on the left, two on the right), a smaller right kidney, a smooth cerebral surface, and a specific keyhole-shaped defect in the skull base, primarily associated with hydrocephalus.

A rare morphological variant: Bilateral accessory optic canal.

Morphologie

January 2025

Department of Anatomy, Faculty of Medicine-Pharmacy, University of Rouen-Normandy, Rouen, France.

The optic canal (OC) transmits the optic nerve (ON) and ophthalmic artery (OA) from the skull base to the orbit. Its morphological variability is narrow, and most commonly its dimensions are being studied. We observed an unexpected variant during a routine investigation of our osteological collection.

Ornithopod dinosaurs appeared during the Middle Jurassic, but it was in the Lower Cretaceous they started their successful evolutionary history. Different phylogenies describing the evolutionary relationships of Ornithopoda are mostly based on cranial features, however there is a lack of well-preserved and complete skulls for the basal member of the clade, hampering our knowledge on the mode and tempo of these herbivorous dinosaurs. Here we describe YLSNHM 01942, a well-preserved skull of a juvenile neornithischian from the Liaoning Province of China.
