• sinusitis
  • Functional Endoscopic Sinus Surgery (FESS) is one of the newer modalities in treatment of Chronic Sinusitis.However, it is not first line of treatment as it may lead to massive bleeding. (wikipedia.org)
  • Sinusitis (or rhinosinusitis) is defined as an inflammation of the mucous membrane that lines the paranasal sinuses and is classified chronologically into several categories: Acute rhinosinusitis - A new infection that may last up to four weeks and can be subdivided symptomatically into severe and non-severe. (wikipedia.org)
  • Headache/facial pain or pressure of a dull, constant, or aching sort over the affected sinuses is common with both acute and chronic stages of sinusitis. (wikipedia.org)
  • Acute sinusitis may be accompanied by thick nasal discharge that is usually green in color and may contain pus (purulent) and/or blood. (wikipedia.org)
  • Occasionally, a large concha bullosa within a turbinate may cause it to bulge sufficiently to obstruct the opening of an adjacent sinus, possibly leading to recurrent sinusitis. (wikipedia.org)
  • Although it is thought that sinusitis or sinus pathology has relation to concha bullosa, no strong statistical correlation has been demonstrated. (wikipedia.org)
  • Functional endoscopic sinus surgery (FESS) is a surgical treatment of sinusitis and nasal polyps, including bacterial, fungal, recurrent acute, and chronic sinus problems. (wikipedia.org)
  • sphenoid
  • They are innervated by the ethmoidal nerves, which branch from the nasociliary nerve of the trigeminal nerve (CN Va). The sphenoidal sinuses, in the sphenoid bone. (wikipedia.org)
  • posterior
  • Touching the posterior wall of the sinus by the tip of the cannula may block the cannula and the fluid may not return on pumping the higginson syringe. (wikipedia.org)
  • functional endosco
  • Variations of the nasal cavity are very important for the otolaryngologist in functional endoscopic sinus surgery. (biomedsearch.com)
  • These data provide very important information to guide the otolaryngologist and/or radiologist in the evaluation of patients with coronal CT which guides functional endoscopic sinus surgery. (biomedsearch.com)
  • If more than three successive puncture shows returning fluid to be persistently purulent, the patient may require functional endoscopic sinus surgery (FESS) and occasionally may need Caldwell-Luc operation. (wikipedia.org)
  • comprises
  • The olfactory neuroepithelium, located in the roof of the nasal chambers, comprises bipolar receptor cells, supporting cells, basal cells, and brush cells. (wikipedia.org)
  • symptoms
  • Pain killers such as naproxen, nasal steroids, and nasal irrigation may be used to help with symptoms. (wikipedia.org)
  • Often a localized headache or toothache is present, and it is these symptoms that distinguish a sinus-related headache from other types of headaches, such as tension and migraine headaches. (wikipedia.org)
  • ventilation
  • 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)
  • Such limited ventilation may be protective for the sinus, as it would help prevent drying of its mucosal surface and maintain a near-sterile environment with high carbon dioxide concentrations and minimal pathogen access. (wikipedia.org)
  • infection
  • Most of the time, an abnormal-looking sinus x-ray means there is an infection. (cancer.org)
  • Infection with the Epstein-Barr virus (EBV) can cause a rare form of non-Hodgkin lymphoma (NHL) called extranodal NK/T-cell lymphoma, nasal type . (cancer.ca)
  • 4 ] A subgroup has shown that paranasal sinus and nasal cavity SCC are associated with human papilloma virus (HPV) infection and that HPV-positive patients may have a better prognosis than those who are HPV-negative. (peacehealth.org)
  • obstruction
  • They can include but are not limited to: Nosebleed Nasal obstruction Proptosis (displacement of the eye) Vision changes Headache The underlying mechanism is unknown, however, Gelbard et al. (wikipedia.org)
  • prosthesis
  • A nasal prosthesis may be held in place with special adhesives, tape, glasses or an extraoral implant (a device surgically attached to the bones of the face that the prosthesis clips to). (cancer.ca)
  • disease
  • This procedure is generally used for inflammatory and infectious sinus disease. (wikipedia.org)
  • Most cases are described as idiopathic and the main antecedents related to parosmia are URTIs, head trauma, and nasal and paranasal sinus disease. (wikipedia.org)
  • Rosai-Dorfman disease, originally known as sinus histiocytosis with massive lymphadenopathy, is a rare disorder of unknown cause that is characterized by abundant histiocytes in the lymph nodes or other locations throughout the body. (wikipedia.org)
  • worsen
  • This pain is typically localized to the involved sinus and may worsen when the affected person bends over or when lying down. (wikipedia.org)
  • pathology
  • Plain Radiological X-rays (Water's view) of sinuses is most specific non- invasive method of diagnosing Antral pathology. (wikipedia.org)
  • procedure
  • The following instruments are used in the procedure: Tilley's Forceps Lichtwitz Antral Trocar Cannula Higginson's Rubber Syringe Nasal Speculum Watery, amber color fluid flowing from cannula, immediately on puncture and containing cholesterol crystals, indicates presence of cyst. (wikipedia.org)
  • occurs
  • verification needed] The confusion occurs in part because migraine involves activation of the trigeminal nerves, which innervate both the sinus region and the meninges surrounding the brain. (wikipedia.org)
  • These become blocked easily by allergic inflammation, or by swelling in the nasal lining that occurs with a cold. (wikipedia.org)
  • bones
  • The biological role of the sinuses is debated, but a number of possible functions have been proposed:[citation needed] Decreasing the relative weight of the front of the skull, and especially the bones of the face. (wikipedia.org)
  • The bones occupied by sinuses are quite variable in these other species. (wikipedia.org)
