  • 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)
  • For example, chronic sinusitis that doesn't respond to drugs, nasal polyps, some cancers, decompressing the eye sockets in Graves ophthalmopathy, decompressing the optic nerve, and removing foreign bodies. (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)
  • The line defines a plane orthogonal to a sagittal plane that divides the maxillary sinus into (1) an anterior-inferior part, and (2) a superior-posterior part. (wikipedia.org)
  • Because the maxillary posterior teeth are close to the maxillary sinus, this can also cause clinical problems if any disease processes are present, such as an infection in any of these teeth. (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)
  • 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)
  • Tomography
  • Sinus x-rays are not done often any more, as many doctors prefer to order a computed tomography (CT) scan instead. (cancer.org)
  • To provide data on bony variations of this region, we performed high resolution computed tomography images of paranasal sinuses on 82 adult patients without sinus pathology and on 90 adult patients with sinus disease. (biomedsearch.com)

  • The ethmoidal cells (sinuses) are present at birth, however by 2 years of age they are recognisable through the use of Computerised Tomography (CT) scanning. (wikipedia.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)
  • 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)
  • passage
  • A small area of special cells in the roof of each nasal passage sends signals to the brain to give the sense of smell. (cancer.gov)
  • 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)
  • Surgery
  • If the nose can't be repaired with reconstructive surgery, a removable nasal prosthesis, or artificial nose, may be made for you. (cancer.ca)
  • bones
  • 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)
  • The sinuses are named for the facial bones in which they are located. (wikipedia.org)
  • 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)
  • chronic
  • Exclusion criteria include evidence of chronic rhinosinusitis, a modified LM score greater than 2, pregnancy, history of prior facial trauma or tumor in the head and neck region, specifically the nasal area, past history of autoimmune disorder affecting the head and neck region (e.g. (clinicaltrials.gov)
  • nose
  • Humans possess four paired paranasal sinuses, divided into subgroups that are named according to the bones within which the sinuses lie: The maxillary sinuses, the largest of the paranasal sinuses, are under the eyes, in the maxillary bones (open in the back of the semilunar hiatus of the nose). (wikipedia.org)
  • They are also innervated by the trigeminal nerve (CN Va). The ethmoidal sinuses, which are formed from several discrete air cells within the ethmoid bone between the nose and the eyes. (wikipedia.org)
  • medical citation needed] Though it is widely held that fungal infections of the nose and paranasal sinuses are not common, most agree that their frequency has been increasing over past decades. (wikipedia.org)
  • discharge
  • The clinical section is focused around the cardinal presenting manifestations of equine respiratory disease: coughing, nasal discharge, increased breathing efforts, respiratory noise, plus a chapter on congenital abnormalities. (whsmith.co.uk)
  • decongestants
  • Topical nasal or ophthalmic decongestants quickly develop tachyphylaxis (a rapid decrease in the response to a drug after repeated doses over a short period of time). (wikipedia.org)
  • occur
  • These cancers usually occur on the roof of the nasal cavity and involve a structure called the cribriform plate, which is a bone deep in the skull. (dmoztools.net)
  • presence
  • Extraction of primary teeth are not considered a risk of OAC due to the presence of developing permanent teeth and the small size of a developing maxillary sinus. (wikipedia.org)
  • 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.
