Sinusitis For example, maxillary sinusitis indicates an infection of the maxillary sinus, which is located in the mid-face. Each sinus -- or group of sinuses in the case of the ethmoids -- is represented on the right and left side of the head. The bony wall between the roots of the molars and the floor of the maxillary sinus may be quite thin, and an infection that begins in your teeth can travel to the adjacent sinus. www.webmd.com /content/article/4/1680_51930.htm?lastselectedguid={5FE84E90-BC77-4056-A91C-9531713CA348}   (2781 words)

Ethmoid bone - Wikipedia, the free encyclopedia On either side of the crista galli, the cribriform plate is narrow and deeply grooved; it supports the olfactory bulb and is perforated by foramina for the passage of the olfactory nerves. A curved lamina, the uncinate process, projects downward and backward from this part of the labyrinth; it forms a small part of the medial wall of the maxillary sinus, and articulates with the ethmoidal process of the inferior nasal concha. The middle ethmoidal cells open into the central part of this meatus, and a sinuous passage, termed the infundibulum, extends upward and forward through the labyrinth and communicates with the anterior ethmoidal cells, and in about 50 per cent. en.wikipedia.org /wiki/Ethmoid_bone   (1249 words)

Expression of TGFß, MMPs, BMP6 in Human Maxillary Sinus/Bone Compartments   (Site not responding. Last check: 2007-10-18) This is influenced by pneumatisation of maxillary sinus in the posterior part of maxilla and bone resorption from both sides - sinus and oral lumens. In patients suffering chronic allergis sinusitis high maxillary bone resorption is observed.The aim of this study was an immunohistochemical investigation of the TGF-beta, BMP6, MMPs 1-3 and TIMP-1 in the tissue compartments as well as a radiometric assessment of the anterior and posterior segments of maxillary bone of patients suffering chronic allergis sinusitis. Conclusion: the involvement of mucosal epithelium in the growth and formation of maxillary sinuses and their pneumatisation in physiological conditions as well as in this pathology is connected with the intense synthesis of cytokines and growth factors, which regulate bone remodelling and turnover of surrounding tissues. iadr.confex.com /iadr/2004Hawaii/techprogram/abstract_41293.htm   (306 words)

eMedicine - Sinusitis, Maxillary, Acute, Surgical Treatment : Article by Steven E Sobol, MD, MSc, FAAP   (Site not responding. Last check: 2007-10-18) The anterior and posterior walls of the maxillary sinus are formed by the corresponding surfaces of the maxilla and are directly related to the cheek skin anteriorly and to the infratemporal fossa posteriorly. Sensory innervation of the maxillary sinus is by the infraorbital nerve, posterolateral nasal nerve, and the anterior, middle, and posterior superior alveolar branches of the second division of the trigeminal nerve. Maxillary sinus mucoceles usually are found incidentally on sinus radiography and are of little significance in the absence of symptomatology or infection. www.emedicine.com /ent/topic340.htm   (5663 words)

ACS :: Treatment Options by Type, Location and Stage Maxillary sinus cancer: Most patients with stage I maxillary sinus cancer have their cancer surgically removed by a maxillectomy (removal of bone and mucosa of the maxillary sinus). People with stage I or stage II maxillary sinus cancer are sometimes treated with radiation therapy alone, especially if they have other medical problems that might significantly increase their risk of surgical complications. Nasal cavity or paranasal sinus rhabdomyosarcoma, a type of sarcoma that is most common among infants and young children, is usually treated with a combination of surgery, radiation therapy, and chemotherapy. www.cancer.org /docroot/CRI/content/CRI_2_4_4X_Treatment_Options_by_Type_Location_and_Stage_75.asp?sitearea=   (814 words)

eMedicine - Sinusitis, Maxillary, Chronic, Surgical Treatment : Article by Ankit M Patel, MD   (Site not responding. Last check: 2007-10-18) The maxillary sinus is housed in the body of the maxilla, with the inferior orbital wall as the superior border, the lateral nasal wall as the medial boundary, the alveolar process of the maxilla as its inferior border, and the canine fossa as the anterior border. The main functional component of the maxillary sinus outflow tract is the ostiomeatal complex, which is collectively constituted by the uncinate process, the maxillary ostium, the infundibulum, and the ethmoid bulla. The maxillary sinus should be inspected with a 30- or 70-degree scope to ensure that no further disease is present within the sinus and that the natural ostium was included in the antrostomy. www.emedicine.com /ent/topic339.htm   (4533 words)

Stanford Cancer Center - Cancer in the Maxillary Sinuses | Cancer Types | Stanford Cancer Center   (Site not responding. Last check: 2007-10-18) The maxillary sinuses are a subset of the paranasal sinuses and can generally be thought of as the sinuses, or cavities, beneath the cheeks and on the sides of the nose. The maxillary sinuses are the most common region that paranasal sinus cancer arises, and most cancers in the maxillary sinuses are squamous cell carcinomas, meaning they arise from flat, thin cells in the epidermis lining the maxillary sinus. Depending on the type and stage of the tumors, maxillary sinus cancers are usually treated with surgery and radiation, and in advanced cases chemotherapy. cancer.stanfordhospital.com /cancerTypes/headAndNeck/paranasalSinuses/maxillarySinus   (572 words)

[No title] He drew an oblique line through the cavity of the maxillary antrum that extended from the medial canthus of the eye to the angle of the mandible when the sinus was viewed in its lateral aspect. Currently, most of maxillary sinus carcinomas in T1 and T2 stages are treated by surgery alone, whereas the T3 and T4 lesions are treated by a combination therapy of surgery and radiation therapy.

Ear, Nose & Throat Journal: The missed maxillary sinus ostium syndrome - Rhinoscopic Clinic This finding represented a case of a "missed maxillary sinus ostium." The two ostia were then joined with a micrcodebrider (figure 1, C and D) to eliminate mucus reeirculation. In the maxillary sinus, secretion transport originates in the floor of the sinus in a stellate pattern. When the missed maxillary sinus ostium syndrome is recognized, endoscopic surgery to connect the natural maxillary ostium with the surgically created middle meatal window may remedy the condition. www.findarticles.com /p/articles/mi_m0BUM/is_8_82/ai_108048952   (806 words)

Paranasal Sinus and Nasal Cavity Cancer:   (Site not responding. Last check: 2007-10-18) Cancer of the paranasal sinus and nasal cavity is a disease in which cancer (malignant) cells are found in the tissues of the paranasal sinuses or nasal cavity. There are several paranasal sinuses, including the frontal sinuses above the nose, the maxillary sinuses in the upper part of either side of the upper jawbone, the ethmoid sinuses just behind either side of the upper nose, and the sphenoid sinus behind the ethmoid sinus in the center of the skull. Treatment of cancer of the paranasal sinus and nasal cavity depends on where the cancer is, the stage of the disease, and the patient's age and overall health. www.acor.org /cnet/62725.html   (3515 words)

Atelectasis, of the maxillary sinus Obstruction of the ostiomeatal unit and more specifically the ethmoid infundibulum is the common factor in these cases; impaired sinus ventilation with a build-up of negative pressure and inward collapse of the thin orbital floor (and sometimes also the other maxillary walls) is thought to be the mechanism (Fig.1). Radiographically this condition has to be differentiated from hypoplasia of the maxillary sinus, showing on the affected side a smaller maxillary sinus with a somewhat lower position of the orbital floor; however, in such cases maxillary pneumatization is incomplete (no penetration of sinus pneumatization into the maxillary ridge and malar eminence). Partial collapse of the maxillary sinus is commonly seen after a Caldwell Luc procedure, but this does not usually lead to cosmetic deformity. www.amershamhealth.com /medcyclopaedia/Volume%20VI%202/atelectasis%20of%20the%20maxillary%20sinus.html   (223 words)

Maxillary Sinus View 2 The maxillary sinus must pump mucous uphill to reach the sinus opening which is at the top. This sinus has a large internal surface area and volume relative to the size of its outflow tract. The flow exits the sinus ostia, then traverses the uncinate process, then drains over the top of the inferior turbinate. www.entnet.org /healthinfo/sinus/sinus_maxillary2.cfm   (63 words)

[No title] A recent CT scan indicates congestion and blockage in the maxillary sinus, but endoscpoic surgery is prevented because of the apparent existence of a vertical piece of bone which runs from under the eye to a point above the teeth. A Caldwell-Luc procedure is an operation intended to treat disease located in the maxillary sinus (the largest sinus which is located in the cheek) only and involves removing disease through an opening directly through the front of the sinus through an incision made under the lip above the gum of the upper teeth. Research has conclusively shown that the natural drainage course of mucous inside the maxillary sinus is towards the natural ostium which is located near the top of the sinus rather than the bottom. ofcn.org /cyber.serv/hwp/hwc/ent/news/ent168.html   (754 words)

View topic - Maxillary Sinus Surgery I had sinus surgery done by a locally well respected ENT in the early 90s only to find out a couple of years later that he did an outdated procedure on me. His bedside manner rated very high and that made people trust him. "maxillary" was one of MANY things on my laundry list of stuff that was done during the 3 hours of surgery.
