ANATOMIC VARIATIONS OF THE CRANIAL VENOUS SINUSES

Archives of Neurology & Psychiatry, 1931
When one compresses the internal jugular veins, the obstruction to the outflow of the cranial circulation is reflected in a rise of the cerebrospinal fluid pressure. This principle is the basis of the Queckenstedt test,1in which the rise of spinal fluid pressure, noted by means of a manometer attached to the lumbar puncture needle, denotes the patency,

CONGENITAL ABSENCE OF THE CRANIAL VENOUS SINUSES ON THE RIGHT

Archives of Otolaryngology, 1941
Anomalies of the cranial venous sinuses when encountered unexpectedly at the operating table may be the cause of hesitation and confusion to the surgeon. If, however, the possibility of such an occurrence has been brought to his attention previously, he will be at least partially prepared with technical procedures to cope with the situation. After the

Morphology and postnatal ontogeny of the cranial endocast and paranasal sinuses of capybara (Hydrochoerus hydrochaeris), the largest living rodent

Journal of morphology, 2021
Recent studies have analyzed and described the endocranial cavities of caviomorph rodents. However, no study has documented the changes in the morphology and relative size of such cavities during ontogeny. Expecting to contribute to the discussion of the

The Comparison of Piriform Aperture, Paranasal Sinuses, and Cranial Dimensions

Journal of Craniofacial Surgery, 2021
Objective: Piriform aperture, paranasal sinuses, and the cranium dimensions were compared with each other and we investigated the alterations depending on the age and gender in these structures. Before the endoscopic sinus surgery, anatomic variations in sinusoidal region and the occurring differences should be considered.

Allergic fungal sinusitis with cranial base erosion

Head & Neck, 1996
Allergic fungal sinusitis (AFS) usually follows a slow, nonaggressive course. However, massive bone destruction can occur, with extension of the disease process outside of the confines of the sinuses.Our series of 28 cases of AFS was reviewed. We identified 6 cases of AFS with definite radiographic evidence of skull base erosion.Histologic diagnostic ...

CRANIAL VENOUS SINUSES

Archives of Surgery, 1938
It has been demonstrated previously that roentgenographic evidence of the relative volumes of the lateral sinuses corresponds to comparative anatomic evidence of the bony markings on the occipital bone.1The value of a clinical method for the demonstration of comparative volumes of the lateral sinuses has been briefly discussed in the presentation of ...

Cranial Base and Paranasal Sinuses

The ethmoidal cells seldom remain contained within the interorbital space. The frontal sinus ex pands naturally to the interior of the frontal bone, including the interior of its orbital plates. Howev er, the anterior ethmoidal cells do the same, com peting for space with the frontal sinus.
