Sinus Implant
A Sinus implant is a medical device that is inserted into the sinus cavity. Implants can be in conjunction with sinus surgery to treat chronic sinusitis and also in sinus augmentation to increase bone structure for placement of dental implants. Types Maxillary implant A maxillary implant is an implant that is placed between jaw and the maxillary sinuses. It is inserted during a sinus lift or augmentation and used to increase the amount of bone to support dental implant A dental implant (also known as an endosseous implant or fixture) is a prosthesis that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, or facial prosthesis or to act as an orthodonti ...s. Implants are either inserted after drilling or by using a non-drilling method known as the osteotome technique. Issues such as bulging within the sinuses can occur with maxillary implants. Maxillary implants can also be made using Choukroun's technique with subsi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Functional Endoscopic Sinus Surgery
Functional endoscopic sinus surgery (FESS), or functional endoscopic sinus surgery, is a procedure that is used to treat sinusitis and other conditions that affect the sinuses. Sinusitis is an inflammation of the sinuses that can cause symptoms such as congestion, headaches, and difficulty breathing through the nose. FESS is a minimally invasive procedure that is performed using an endoscope, a thin, rigid tube with a camera on the end. The endoscope is inserted through the nostrils, allowing the surgeon to visualize the inside of the nasal passages and sinuses. The surgeon can then remove any tissue or obstruction that is blocking the sinuses, such as swollen or infected tissue. FESS is generally considered to be a safe and effective treatment for sinusitis and other conditions that affect the sinuses. It can help to alleviate symptoms and improve the overall functioning of the sinuses. However, as with any medical procedure, there are potential risks and complications that shoul ...

Sinusitis
Sinusitis, also known as rhinosinusitis, is inflammation of the nasal mucosa, mucous membranes that line the paranasal sinuses, sinuses resulting in symptoms that may include thick Mucus#Respiratory system, nasal mucus, a nasal congestion, plugged nose, and Orofacial pain, facial pain. Other signs and symptoms may include fever, headaches, a hyposmia, poor sense of smell, sore throat, a feeling that phlegm is oozing out from the back of the nose to the throat along with a necessity to clear the throat frequently and frequent attacks of cough. Generally sinusitis starts off as a common viral infection like common cold. This infection generally subsides within 5 to 7 days. During this time the nasal structures can swell and facilitate the stagnation of fluids in sinuses that leads to acute (medicine), acute sinusitis which lasts from 6th day of the infection to 15th day. From the 15th day to 45th day of the infection comes the subacute stage followed by chronic (medicine), chronic ...

Sinus Lift
Maxillary sinus floor augmentation (also termed sinus lift, sinus graft, sinus augmentation or sinus procedure) is a surgical procedure which aims to increase the amount of bone in the posterior maxilla (upper jaw bone), in the area of the premolar and molar teeth, by lifting the lower Schneiderian membrane (sinus membrane) and placing a bone graft. When a tooth is lost, the alveolar process begins to remodel. The vacant tooth socket collapses as it heals leaving an edentulous (toothless) area, termed a ''ridge''. This collapse causes a loss in both height and width of the surrounding bone. In addition, when a maxillary molar or premolar is lost, the maxillary sinus pneumatizes in this region which further diminishes the thickness of the underlying bone. Overall, this leads to a loss in volume of bone that is available for implantation of dental implants, which rely on osseointegration (bone integration), to replace missing teeth. The goal of the sinus lift is to graft extra bo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Dental Implant
A dental implant (also known as an endosseous implant or fixture) is a prosthesis that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, or facial prosthesis or to act as an orthodontic anchor. The basis for modern dental implants is a biologic process called osseointegration, in which materials such as titanium or zirconia form an intimate bond to bone. The implant fixture is first placed so that it is likely to osseointegrate, then a dental prosthetic is added. A variable amount of healing time is required for osseointegration before either the dental prosthetic (a tooth, bridge or denture) is attached to the implant or an abutment is placed which will hold a dental prosthetic/crown. Success or failure of implants depends on the health of the person receiving the treatment, drugs which affect the chances of osseointegration, and the health of the tissues in the mouth. The amount of stress that will be put on the impla ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Rhinoplasty
Rhinoplasty ( grc, ῥίς, rhī́s, nose + grc, πλάσσειν, plássein, to shape), commonly called nose job, medically called nasal reconstruction is a plastic surgery procedure for altering and reconstructing the nose. There are two types of plastic surgery used – reconstructive surgery that restores the form and functions of the nose and cosmetic surgery that changes the appearance of the nose. Reconstructive surgery seeks to resolve nasal injuries caused by various traumas including blunt, and penetrating trauma and trauma caused by blast injury. Reconstructive surgery can also treat birth defects, breathing problems, and failed primary rhinoplasties. Rhinoplasty may remove a bump, narrow nostril width, change the angle between the nose and the mouth, or address injuries, birth defects, or other problems that affect breathing, such as a deviated nasal septum or a sinus condition. Surgery only on the septum is called a septoplasty. In closed rhinoplasty and open rhi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Plaster Of Paris
Plaster is a building material used for the protective or decorative coating of walls and ceilings and for moulding and casting decorative elements. In English, "plaster" usually means a material used for the interiors of buildings, while "render" commonly refers to external applications. Another imprecise term used for the material is stucco, which is also often used for plasterwork that is worked in some way to produce relief decoration, rather than flat surfaces. The most common types of plaster mainly contain either gypsum, lime, or cement,Franz Wirsching "Calcium Sulfate" in Ullmann's Encyclopedia of Industrial Chemistry, 2012 Wiley-VCH, Weinheim. but all work in a similar way. The plaster is manufactured as a dry powder and is mixed with water to form a stiff but workable paste immediately before it is applied to the surface. The reaction with water liberates heat through crystallization and the hydrated plaster then hardens. Plaster can be relatively easily worked wit ...

Enophthalmos
Enophthalmos is a posterior displacement of the eyeball within the orbit. It is due to either enlargement of the bony orbit and/or reduction of the orbital content, this in relation to each other. It should not be confused with its opposite, exophthalmos, which is the anterior displacement of the eye. It may be a congenital anomaly, or be acquired as a result of trauma (such as in a blowout fracture of the orbit), Horner's syndrome (apparent enophthalmos due to ptosis), Marfan syndrome, Duane's syndrome, silent sinus syndrome or phthisis bulbi Phthisis bulbi is a shrunken, non-functional eye. It may result from severe eye disease, inflammation or injury, or it may represent a complication of eye surgery. Treatment options include insertion of a prosthesis, which may be preceded by e ....

Steroid-eluting Sinus Stents
Steroid-eluting sinus stents may be used in addition to endoscopic sinus surgery. They are, however, of unclear benefit as of 2015. One version releases mometasone furoate. It is a bioabsorbable steroid-eluting stent. It delivers steroids over a 30-day period prior to dissolving. Society and culture A number of brands exist including Relieva Stratus Spacer and Propel sinus implant. Approval One brand received pre-market approval from the FDA The United States Food and Drug Administration (FDA or US FDA) is a federal agency of the Department of Health and Human Services. The FDA is responsible for protecting and promoting public health through the control and supervision of food s ... in 2011. References {{reflist Implants (medicine) Nose surgery ...

Bioresorbable Stents
In medicine, a stent is any device which is inserted into a blood vessel or other internal duct to expand it to prevent or alleviate a blockage. Traditionally, such devices are fabricated from metal mesh and remain in the body permanently or until removed through further surgical intervention. A bioresorbable stent (also called bioresorbable scaffold, biodegradable stent or naturally-dissolving stent) serves the same purpose, but is manufactured from a material that may dissolve or be absorbed in the body. Background The use of metal drug-eluting stents presents some potential drawbacks. These include a predisposition to late stent thrombosis, prevention of late vessel adaptive or expansive remodeling, hindrance of surgical revascularization, and impairment of imaging with multislice CT. To overcome some of these potential drawbacks, several companies are pursuing the development of bioresorbable scaffolds or bioabsorbable stents. Like metal stents, placement of a bioresorbable ...

Middle Nasal Concha
The medial surface of the labyrinth of ethmoid consists of a thin lamella, which descends from the under surface of the cribriform plate, and ends below in a free, convoluted margin, the middle nasal concha (middle nasal turbinate). It is rough, and marked above by numerous grooves, directed nearly vertically downward from the cribriform plate; they lodge branches of the olfactory nerves, which are distributed to the mucous membrane covering the superior nasal concha.
