• pharynx
  • The rapidly dividing cells in the mucosal membranes of the pharynx and paranasal sinuses are very sensitive to the effects of radiation. (ajnr.org)
  • 1 The naso-pharynx and sphenoid sinus are especially vulnerable to the effects of radiation treatment of nasopharyngeal carcinoma, because they receive the full radiation dose. (ajnr.org)
  • In the pharynx, these MR abnormalities often resolve, whereas in the paranasal sinuses there is a high incidence of persistent minor abnormalities, including mucosal thickening and fluid levels, months or years after treatment for nasopharyngeal carcinoma. (ajnr.org)
  • Upper respiratory tract infections (URI or URTI) are illnesses caused by an acute infection which involves the upper respiratory tract including the nose, sinuses, pharynx or larynx. (wikipedia.org)
  • ostium
  • The pressure differentials are directed to the center of the sinuses producing mucosal edema, transudation, and mucosal-or submucosal-hematoma, leading to further occlusion of the sinus ostium. (wikipedia.org)
  • The magnitude of the pressure difference needed to produce a barotrauma probably shows great individual variation and is related to the size of the sinus ostium and the rate of ambient pressure change. (wikipedia.org)
  • The results of experimental studies suggest that the natural ventilation-rate of a sinus with a single sinus ostium (opening), is extremely slow. (wikipedia.org)
  • secretions
  • As with other mucoceles, they occur from accumulation and retention of mucoid secretions within the sinus and in turn can lead to thinning, distension and erosion of one or more of its bony walls. (radiopaedia.org)
  • The MR imaging reports of patients undergoing imaging after radiation therapy treatment for nasopharyngeal carcinoma between 1995 and 2006 were reviewed to identify patients with exophytic polyps in the nasopharynx or a mass in the sphenoid sinus that did not have the typical features of posttreatment inflammatory sinus changes (mild thickening and mucosal enhancement and/or secretions of high T2 and low T1 signal intensity). (ajnr.org)
  • Antihistamines can reduce mucus secretions and sinus swelling. (sinustip.info)
  • A person with a sinus infection often has nasal congestion with thick nasal secretions, fever, and cough (WebMD). (wikipedia.org)
  • mucoceles
  • 9. Razmpa E, Naghibzadeh B, Bagheri A, Sadeghi M, Khak M. The clinical manifestation, evaluation and surgical management of sphenoid sinus mucoceles: a case series and literature review. (radiopaedia.org)
  • The main differential consideration in an opacified sinus is an expansile or erosive process in the sphenoid sinus (e.g., mucoceles or polyps). (blogspot.com)
  • septum
  • Material and Methods: - Sphenoid sinus septum anatomy was initially studied in 100 consecutive CT exams of the paranasal sinuses. (uzh.ch)
  • Results: - In 33 of the 43 cases (77%), the adenoma was localized directly above the insertion of a sphenoid sinus septum in the floor of the sella. (uzh.ch)
  • Discussion: - Sphenoid sinus septum anatomy is highly variable. (uzh.ch)
  • Most patients ask to remove a bump, narrow nostril width, change the angle between the nose and the mouth, as well as correct injuries, birth defects, or other problems that affect breathing, such as deviated nasal septum or a sinus condition. (wikipedia.org)
  • anterior
  • Surgical options include endoscopic transnasal sphenoidotomy with sufficient removal of the anterior and inferior walls of the sinus. (radiopaedia.org)
  • The apertures are located high on the anterior walls of the sinuses themselves. (wikipedia.org)
  • tumor
  • NMPMs in the nasopharynx and sphenoid sinus are rare complications after radiation therapy to the skull base, but the radiologist needs to be aware of their appearance so that they can be considered in the differential diagnosis of suspected tumor recurrence. (ajnr.org)
  • When a sinus becomes inflamed, due to an allergic reaction, a tumor, or an infection, the inflammation will thwart the steady flow of mucus and this results in a pain akin to that of a headache. (sinustip.info)
  • If a fast-growing tumor erodes the floor of the sinus, the vidian nerve could be in danger. (wikipedia.org)
  • Treatment of sphenoid wing meningiomas often depends on the location and size of the tumor. (wikipedia.org)
  • saline
  • Antifungal medication or natural seeds and extracts can be added in the saline solution if suspicions of fungal sinus itis exist. (sinustip.info)
  • the saline solution remains in the sinus es for a while, and is later thrown out and the cills movements are resumes. (sinustip.info)
  • The mechanism of action is actual flushing of the allergens from the nasal and sinus passages with large volume saline irrigation. (wikipedia.org)
  • Large volume nasal saline irrigation as a sinus rinse is a preferred method. (wikipedia.org)
  • passages
  • This sinus connects with the nasal passages, and is part of an intricate system of air passageways that warm incoming air. (madsci.org)
  • cranial
  • We recently examined a patient who developed a nearly complete unilateral third cranial nerve palsy attributed to sphenoid sinus aspergillosis. (lww.com)
  • In common usage, "sinus" usually refers to the paranasal sinuses, which are air cavities in the cranial bones, especially those near the nose and connecting to it. (wikipedia.org)
  • Of all cranial meningiomas, about 20% of them are in the sphenoid wing. (wikipedia.org)
  • The differential diagnosis for sphenoid wing meningioma includes other types of tumors such as optic nerve sheath meningioma, cranial osteosarcoma, metastases, and also sarcoidosis. (wikipedia.org)
  • foramen
  • Coronal images reveal projection of the sphenoid sinus sidewall beyond the foramen rotundum (r). (blogspot.com)
  • The most specific evidence of such a process is gross sinus wall erosion and flattening or erosion of the rims of vidian canal or the foramen rotundum. (blogspot.com)
