Angiomatosis of the paranasal sinuses
The Laryngoscope, 2012AbstractAngiomatosis is a rare benign lesion of the head and neck that can be mistaken for either a vascular malformation or malignant disease as a result of its infiltrative nature. The recurrence rate of angiomatosis requiring surgery is reported to be >90%, and as such the otolaryngologist treating this condition should endeavor to remove all ...

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 ...

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.

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.

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.

1990
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 ...

Myxoma of the paranasal sinuses
The Journal of Laryngology & Otology, 1994AbstractMyxomas of the paranasal sinuses are rare but well described in the literature. They may be related to dental malformations or missing teeth, but may also occur without any such abnormalities. Their local aggressiveness and ability to erode bone should not be underestimated, and they should be totally removed whenever possible. A case of myxoma
