Microsurgical
Microsurgery is a general term for surgery requiring an operating microscope. The most obvious developments have been procedures developed to allow anastomosis of successively smaller blood vessels and nerves (typically 1 mm in diameter) which have allowed transfer of tissue from one part of the body to another and re-attachment of severed parts. Microsurgical techniques are utilized by several specialties today, such as general surgery, ophthalmology, orthopedic surgery, gynecological surgery, otolaryngology, neurosurgery, oral and maxillofacial surgery, endodontic microsurgery, plastic surgery, podiatric surgery and pediatric surgery. History Otolaryngologists were the first physicians to use microsurgical techniques. A Swedish otolaryngologist, Carl-Olof Siggesson Nylén (1892–1978), was the father of microsurgery. In 1921, in the University of Stockholm, he built the first surgical microscope, a modified monocular Brinell-Leitz microscope. At first he used it for ope ...

Operating Microscope
An operating microscope or surgical microscope is an optical microscope specifically designed to be used in a surgical setting, typically to perform microsurgery. Design features of an operating microscope are: magnification typically in the range from 4x-40x, components that are easy to sterilize or disinfect in order to ensure cross-infection control. There is often a prism that allows splitting of the light beam in order that assistants may also visualize the procedure or to allow photography or video to be taken of the operating field. Typically an operating microscope might cost several thousand dollars for a basic model, more advanced models may be much more expensive. Additionally, specialized microsurgical instruments may be required to make full use of the improved vision the microscope affords. It can take time to master use of an operating microscope. Fields of medicine that make significant use of the operating microscope include plastic surgery, dentistry (esp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsurgical Endodontics
Microsurgical endodontics is that aspect of endodontics Endodontics () is the Specialty (dentistry), dental specialty concerned with the study and treatment of the dental pulp. Overview Endodontics encompasses the study (practice) of the basic and clinical sciences of normal dental pulp, the etiolo ... which evolved after the introduction of the Surgical Operating Microscope (SOM) to endodontics in the early 1990s. The recent addition of SOM's to endodontic therapy can allow better visualization and management of the surgical field by endodontists during endodontic procedures (mostly root canal treatment) through magnification and greatly improved high intensity lighting. SOM's typically magnify in the 4X to 25X range. The other commonly used magnification aide, through lens eyeglass mounted surgical telescopes, provide 2.5X to 4.5X magnification. Surgical operating microscopes have a steep learning curve and require training, as well as patience and practice to master. Some ...

Anastomosis
An anastomosis (, : anastomoses) is a connection or opening between two things (especially cavities or passages) that are normally diverging or branching, such as between blood vessels, leaf veins, or streams. Such a connection may be normal (such as the foramen ovale in a fetus' heart) or abnormal (such as the patent foramen ovale in an adult's heart); it may be acquired (such as an arteriovenous fistula) or innate (such as the arteriovenous shunt of a metarteriole); and it may be natural (such as the aforementioned examples) or artificial (such as a surgical anastomosis). The reestablishment of an anastomosis that had become blocked is called a reanastomosis. Anastomoses that are abnormal, whether congenital or acquired, are often called fistulas. The term is used in medicine, biology, mycology, geology, and geography. Etymology Anastomosis: medical or Modern Latin, from Greek ἀναστόμωσις, anastomosis, "outlet, opening", Greek ana- "up, on, upon", stoma "mouth" ...

A ''ghazi'', or ''gazi'' (, , plural ''ġuzāt'') is an individual who participated in ''ghazw'' (, '' ''), meaning military expeditions or raids against non-Muslims. The latter term was applied in early Islamic literature to expeditions led by the Islamic prophet Muhammad, and later taken up by Turkic military leaders to describe their wars of conquest. In the context of the wars between Russia and the Muslim peoples of the Caucasus, starting as early as the late 18th century's Sheikh Mansur's resistance to Russian expansion, the word usually appears in the form ''gazavat'' (). In English-language literature, the ''ghazw'' often appears as '' razzia'', a borrowing through French from Maghrebi Arabic.
