  • To investigate the feasibility and efficacy of endoscopic sinus surgery for sinonasal malignancy. (readbyqxmd.com)
  • Exemplary paranasal sinus conditions are sinus inflammation due to functional endoscopic sinus surgery (FESS) and rhinosinusitis. (patents.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)
  • He is an expert in endoscopic sinus and laryngeal/voice surgery. (wikipedia.org)
  • In 1994, on a WHO fellowship, he worked with David W. Kennedy in the University of Pennsylvania Medical Center and learned functional endoscopic sinus surgery (FESS). (wikipedia.org)
  • bone
  • The conchae or turbinates are delicate scrolls of bone that are attached laterally in the nasal passage and contain the conchal sinuses. (merckvetmanual.com)
  • The following difficulties may arise during antral lavage: Hard Bone: The wall of the maxillary sinus may be hard, rendering the procedure difficult. (wikipedia.org)
  • recurrent
  • The following are treatment options for recurrent maxillary sinus cancer. (cancer.ca)
  • External beam radiation therapy may be offered for recurrent maxillary sinus cancer if you had surgery to treat the original tumour. (cancer.ca)
  • You may be offered chemotherapy for recurrent maxillary sinus cancer. (cancer.ca)
  • Targeted therapy is sometimes used to treat recurrent maxillary sinus cancer. (cancer.ca)
  • Cetuximab (Erbitux) is the targeted therapy drug most often used for recurrent maxillary sinus cancer. (cancer.ca)
  • Consider imaging studies in recurrent or unclear cases: some sinus involvement is frequent early in the course of uncomplicated viral URI Treatment comprises symptomatic support usually via analgesics for headache, sore throat and muscle aches. (wikipedia.org)
  • venous
  • Thus composition of gas content in the maxillary sinus is similar to venous blood, with high carbon dioxide and lower oxygen levels compared to breathing air. (wikipedia.org)
  • lacrimal
  • It also sends postganglionic parasympathetic fibers to the lacrimal nerve (a branch of the Ophthalmic nerve, also part of the trigeminal nerve) via the zygomatic nerve, a branch of the maxillary nerve (from the trigeminal nerve), which then arrives at the lacrimal gland. (wikipedia.org)
  • mucosal surface
  • 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)
  • mucus
  • On radiographs, there is opacification (or cloudiness) of the usually translucent sinus due to retained mucus. (wikipedia.org)
  • cysts
  • Lateral and dorsoventral radiographs of the skull may reveal fluid lines, sinus cysts, solid masses, or lytic/proliferative changes associated with dental disease and neoplasia. (merckvetmanual.com)
  • branches of the maxillary nerve
  • The pterygopalatine ganglion (of Meckel), the largest of the parasympathetic ganglia associated with the branches of the maxillary nerve, is deeply placed in the pterygopalatine fossa, close to the sphenopalatine foramen. (wikipedia.org)
  • trigeminal
  • 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)
  • They are innervated by the trigeminal nerve (CN Va). The paranasal air sinuses are lined with respiratory epithelium (ciliated pseudostratified columnar epithelium). (wikipedia.org)
  • Orbital
  • Orbital venography is difficult to perform, but it is excellent in diagnosing occlusion of the cavernous sinus. (wikipedia.org)
  • headache
  • 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)
  • lavage
  • Luma Wire Transillumination: This technique has a number of advantages over antral Lavage, such as: 1) Discovery of the location of the Maxillary Sinus with greater accuracy. (wikipedia.org)
  • clinical
  • The diagnosis of cavernous sinus thrombosis is made clinically, with imaging studies to confirm the clinical impression. (wikipedia.org)
  • Cavernous sinus thrombosis is a clinical diagnosis with laboratory tests and imaging studies confirming the clinical impression. (wikipedia.org)
