TRANSILLUMINATION OF PARANASAL SINUSES
Journal of the American Medical Association, 1958I have often been impressed by the importance placed by medical students and some physicians on transillumination of the paranasal sinuses. The presence or absence of clear transillumination is sometimes regarded as a significant sign, without consideration of other physical findings or the type of skull being transilluminated.

Neurofibromas of the paranasal sinuses
The Journal of Laryngology & Otology, 1988Two cases of neurofibroma of the paranasal sinuses are presented. The tumours presented as space-occupying lesions and were treated by local excision. Histologically one was a typical neurofibroma, whilst the other showed some features of a schwannoma. The patients show no evidence of tumour recurrence at 18 and 6 months respectively.

Neuroradiology, 1985
CT scanning has allowed the radiologist to image paranasal sinus disease with an accuracy and detail never before attainable. This information has made the imager an important member of the physician team that evaluates the operability and treatment planning of these patients.

Aspergillosis of the Paranasal Sinuses
Archives of Otolaryngology - Head and Neck Surgery, 1975Aspergillosis of the paranasal sinuses may occur as a chronic disease in an otherwise healthy person. This infection is usually confined to a single paranasal sinus, the maxillary antrum, though it can involve the orbit and may initiate with findings of proptosis and decreased vision.

Meningioma of the paranasal sinuses [PDF]
Neuroradiology, 1979 Meningiomas originating in the paranasal sinuses are rare. These tumors are thought to arise from embryonal arachnoid nests which were pinched off and left behind during embryonic development. We have described various radiographic findings of two patients with meningioma arising in the paranasal sinuses (frontal sinus origin in a 65-year-old female ...

Aspergillosis of the paranasal sinuses
Neuroradiology, 1992The CT appearances of 13 cases of pathologically proven aspergillosis involving paranasal sinuses were reviewed. Symptoms included rhinorrhea, nasal obstruction, headache, facial pain and foul smell from the nose. At operation, these lesions appeared yellowish, brownish, grey or black in colour, and contained dirty or muddy material.

While the gas-filled cavities of the face, the paranasal sinuses, are one of the most complex bony areas of the body, their exact function remains unknown. Many pathologic conditions affect the sinuses and imaging is central to their diagnosis. Plain radiographs (Caldwell, Waters, lateral and submentovertex projections performed with a horizontal beam ...

Tumors of the Paranasal Sinuses
Otolaryngologic Clinics of North America, 1988Benign and malignant tumors, including polyps, represent conditions that occur frequently enough to be considered in the differential diagnosis of sinus disease. The locations and extent of these lesions (especially malignant tumors) should be evaluated by CT and MRI.

Pathophysiology of the Paranasal Sinuses
Acta Oto-Laryngologica, 1977The maxillary ostium is narrower when the subject is recumbent than when sitting. The oxygen content in the sinus is related to the patency of the ostium and to some extent to its size. A 90% gas exchange in the sinus normally requires only 5 minutes. The exchange is faster during nasal than during oral breathing.
