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.

Meningiomas of the Paranasal Sinuses
American Journal of Rhinology, 2001Extracranial meningiomas are rare tumors, comprising ∼2% of all meningiomas. Previously reported sites include the orbit, parapharyngeal space, and rarely, the paranasal sinuses. A retrospective chart review of patients with meningiomas was performed over the last 25 years, and three patients were identified with meningiomas involving the paranasal ...

Malignancies of the Paranasal Sinuses
Archives of Otolaryngology - Head and Neck Surgery, 1959Malignant disease of the paranasal sinuses is not common. During a period of approximately 25 years only 62 cases have been seen at the University of Chicago Clinics. The series includes only tumors considered to have originated within the sinuses. Tumors of the nose, palate, orbit, skin, or intracranial structures which have invaded the sinuses have ...

Exostoses of the paranasal sinuses
The Laryngoscope, 2010AbstractWhile bony exostoses of the external auditory canal have long been recognized as a complication of cold‐water swimming, bony exostoses of the paranasal sinuses have not been previously reported. We present an unusual case of multiple exostoses of the paranasal sinuses, which began coincident with nasal irrigation with cold gentamicin solution ...

Aspergillosis of the paranasal sinuses.
Radiology, 1985The authors examined 105 proved cases of aspergillosis involving the paranasal sinuses or nasal fossa. Mycosis was always unilateral, and the maxillary sinus was infected in all cases. Early stages were manifested by an intraluminal soft-tissue mass representing the mass of mycelia.

1986
The paranasal sinuses are air spaces within the skull and the maxillae. Tumours most commonly involve the antrum lying within the maxilla. It is lined with ciliated mucous secretory epithelium, the mucus draining through openings into the nose. Lymphatic drainage is to the retropharyngeal nodes (behind the pharynx).

Cancer of the Paranasal Sinuses
Surgical Clinics of North America, 1986Cancers of the paranasal sinuses, although rare, continue to cause the death of more than half of patients afflicted with them. The use of combined therapy (surgery and irradiation) has effected some improvement in control, particularly with better surgical and radiation techniques.
