Cranial Base and Paranasal Sinuses

2001
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.

CRANIAL AND INTRACRANIAL COMPLICATIONS OF ACUTE FRONTAL SINUSITIS

Journal of the American Medical Association, 1940
The most common complications of acute frontal sinusitis, particularly that which follows swimming, are abscess of the frontal lobe and osteomyelitis of the frontal bone. 1 Within recent years the rhinologists and neurosurgeons have adopted more or less successful methods of dealing with these complications. Nevertheless the problems presented by these

Cranialization of the frontal sinus—the final remedy for refractory chronic frontal sinusitis [PDF]

Journal of Neurosurgery, 2012
Object Chronic sinusitis can be a debilitating disease with significant impact on quality of life. Frontal sinusitis has a relatively low prevalence, but complications can be severe due to its anatomical location. After failure of conservative measures, typically endoscopic procedures are performed to improve the drainage of the frontal sinus.

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

Tumors of the Paranasal Sinuses, Nasal and Cranial Cavities

2014
Secondary cysts and tumors presenting as space occupying lesions in the orbit may originate from the nose and paranasal sinuses and the cranial cavity commonly include mucoceles, meningiomas, malignant epithelial neoplasms, and vascular malformations. The histopathological, clinical, imaging, and therapeutic aspects of these lesions are covered in this

Transfacial Approaches of the Ventral Cranial Base, Paranasal Sinuses, and the Extra Cranial Fossae

2020
Sinonasal neoplasms often involve the anterior cranial base. Squamous cell carcinoma (SCC) accounts for up to 60% of cases. Tumors of the nasal fossae reach the ethmoid complex cranially, and involve the maxillary sinus, and orbits laterally. Tumors in the upper portion of the nasal cavity and ethmoid cells involve the cribriform plate, lamina ...

Adult Cranial Dura II: Venous Sinuses and Their Extrameningeal Contributions

Journal of Computer Assisted Tomography, 2003
This is the second of two articles designed to provide detailed user-friendly schematics of the adult dural vascular anatomy. It supplements the first article on the intrinsic meningeal arteries and veins by describing the dural venous sinuses along with their three remaining connections: to the brain, to the diploë, and to the extracranial soft ...

Tumors of the Cranial and Nasal Cavities and Paranasal Sinuses [PDF]

, 2005
Benign epithelial tumors of the nose and paranasal sinuses include squamous and inverted papilloma and pleomorphic adenoma originating from minor salivary glands.2,3 Papillomas of the sinonasal tract originate from squamous or Schneiderian epithelium. Although they are benign, these tumors, which most commonly occur in white males after 50 years of age,

CRANIAL VENOUS SINUSES

Archives of Surgery, 1936
In a previous communication 1 one of us (B. W.) has described the normal anatomic variations in the cranial venous sinus patterns, particularly in the region of the torcular Herophili. As a part of that study, it was noted that the markings on the occipital bone closely corresponded to the differences in the volume of the lateral sinuses and followed ...

Undifferentiated Carcinoma of the Sinuses and Cranial Basis Successfully Treated with Radiochemotherapy

Chemotherapy, 1994
The frustration and disappointment in managing advanced cancers of the nose and paranasal sinuses are well known. We report a case of a successful treatment of such a tumour in a 37-year-old soldier, using a combination of therapy including surgery, chemotherapy and radiation. Each mode of treatment is discussed.
