Stafne Static Bone Cyst
The Stafne defect (also termed Stafne's idiopathic bone cavity, Stafne bone cavity, Stafne bone cyst (misnomer), lingual mandibular salivary gland depression, lingual mandibular cortical defect, latent bone cyst, or static bone cyst) is a depression of the human mandible, mandible, most commonly located on the lingual surface (the side nearest the tongue). The Stafne defect is thought to be a normal anatomical variant, as the depression is created by ectopic salivary gland tissue associated with the submandibular gland and does not represent a pathology, pathologic lesion as such. This cavity is commonly observed on panoramic radiograph. Classification It is a classed as a pseudocyst, since there is no epithelium, epithelial lining or fluid content. This defect is usually considered with other cysts of the jaws, since it can be mistaken for such on a radiograph. Two classification systems were proposed to categorize Stafne bone cavity based on its depth and content. Various s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sublingual Salivary Gland
The sublingual gland (''glandula sublingualis'') is a seromucous polystomatic exocrine gland. Located underneath the oral diaphragm (''diaphragma oris''), the sublingual gland is the smallest and most diffuse of the three major salivary glands of the oral cavity, with the other two being the submandibular and parotid. The sublingual gland provides approximately 3-5% of the total salivary volume. Structure The submandibular glands are located anterior and superior to the submandibular gland and inferior and lateral to the tongue, as well as inferior to the mucous membrane of the floor of the mouth. They are bound laterally by the bone of the mandible and inferolaterally by the mylohyoid muscle. The glands can be palpated posteriorly to each mandibular canine. Placing one index finger within the mouth and the fingertips of the opposite hand outside it, the compressed gland is manually palpated between the inner and outer fingers.Illustrated Anatomy of the Head and Neck, Fehrenb ...

Ionian League
The Ionian League (; , ; or , , in ), also called the Panionic League, was a confederation formed at the end of the Meliac War in the mid-7th century BC comprising twelve Ionian Greek city-states (a dodecapolis, of which there were many others), and eventually thirteen city-states with the admission of Smyrna. The earliest union of city-states in the area was the Ionian League. The League survived through the Hellenistic and Roman periods, until the 3rd century AD. Overview The twelve ancient city-states were listed by Herodotus as:Herodotus. ''The Histories''1.142 *Miletus, Myus, and Priene — all located in Caria (a region in Asia Minor). The three Greek cities spoke the same Ionic subdialect. Starting from the 7th century BC, Greek-Carian bilinguals in Caria suggest the Carians shared their former ancestral land amicably with the Greeks. The Carian language is not Greek but is a remnant of the Anatolian language group that dominated Anatolia before being pushed out b ...

Klazomenai
Klazomenai () or Clazomenae was one of the 12 cities of ancient Ionia (the others being Chios, Samos, Phocaea, Erythrae, Teos, Lebedus, Colophon (city), Colophon, Ephesus, Priene, Myus, and Miletus). It is located at the south coast of Smyrna Gulf, Ionia, and a member of the Ionian League. It was one of the first cities to issue silver coinage. Its ruins are now located in the modern town Urla, İzmir, Urla near İzmir in İzmir Province, Turkey. Location Klazomenai is located in modern Urla, İzmir, Urla (Vourla (Βουρλά) in Greek) on the western coast of Anatolia, on the southern coast of the Gulf of İzmir, at about west of İzmir. The city was originally located on the mainland at Limantepe, but probably during the early fifth-century BC Ionian Revolt from the Persian Empire, Persians, it was moved to the Karantina Island just off the coast. Soon after that, the city of Chyton was founded on the mainland the late fifth-century BC. Both cities had conflictual relations b ...

Edward C
Edward is an English male name. It is derived from the Anglo-Saxon name ''Ēadweard'', composed of the elements '' ēad'' "wealth, fortunate; prosperous" and '' weard'' "guardian, protector”. History The name Edward was very popular in Anglo-Saxon England, but the rule of the Norman and Plantagenet dynasties had effectively ended its use amongst the upper classes. The popularity of the name was revived when Henry III named his firstborn son, the future Edward I, as part of his efforts to promote a cult around Edward the Confessor, for whom Henry had a deep admiration. Variant forms The name has been adopted in the Iberian peninsula since the 15th century, due to Edward, King of Portugal, whose mother was English. The Spanish/Portuguese forms of the name are Eduardo and Duarte. Other variant forms include French Édouard, Italian Edoardo and Odoardo, German, Dutch, Czech and Romanian Eduard and Scandinavian Edvard. Short forms include Ed, Eddy, Eddie, Ted, Teddy a ...

Sialography
Sialography (also termed radiosialography) is the radiographic examination of the salivary glands. It usually involves the injection of a small amount of contrast medium into the salivary duct of a single gland, followed by routine X-ray projections. The resulting image is called a sialogram. Sialography has largely been replaced by sialoendoscopy and cross-sectional imaging, such as CT, MRI and ultrasonography. Uses This procedure is indicated when there is recurrent swelling and pain on the face but ultrasound has not revealed any problems. If Sjögren syndrome (also known as Sicca syndrome, an autoimmune disease that affects the lacrimal and salivary glands, causing reduced tears and saliva production) is suspected, this procedure is useful. Besides, when interventional proecudre is planned such as stone removal from salivary ducts or dilatation of the strictures in the salivary gland, this procedure is also indicated. However, for those who are pregnant, with allergy to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palpation
Palpation is the process of using one's hands to check the body, especially while perceiving/diagnosing a disease or illness. Usually performed by a health care practitioner, it is the process of feeling an object in or on the body to determine its size, shape, firmness, or location (for example, a veterinarian can feel the stomach of a pregnant animal to ensure good health and successful delivery). Palpation is an important part of the physical examination; the somatosensory system, sense of touch is just as important in this examination as the visual perception, sense of sight is. Physicians develop great skill in palpating problems below the surface of the body, becoming able to detect things that untrained persons would not. Mastery of anatomy and much practice (learning method), practice are required to achieve a high level of skill. The concept of being able to detect or notice subtle tactile medical sign, signs and to recognize their significance or implications is called ...

Biopsy
A biopsy is a medical test commonly performed by a surgeon, interventional radiologist, an interventional radiologist, or an interventional cardiology, interventional cardiologist. The process involves the extraction of sampling (medicine), sample Cell (biology), cells or Biological tissue, tissues for examination to determine the presence or extent of a disease. The tissue is then Histopathology, fixed, dehydrated, embedded, sectioned, stained and mounted before it is generally examined under a microscope by a pathologist; it may also be analyzed chemically. When an entire lump or suspicious area is removed, the procedure is called an excisional biopsy. An incisional biopsy or core biopsy samples a portion of the abnormal tissue without attempting to remove the entire lesion or tumor. When a sample of tissue or fluid is removed with a needle in such a way that cells are removed without preserving the histological architecture of the tissue cells, the procedure is called a needle as ...

Squamous Cell Carcinoma
Squamous-cell carcinoma (SCC), also known as epidermoid carcinoma, comprises a number of different types of cancer that begin in squamous cells. These cells form on the surface of the skin, on the lining of hollow organs in the body, and on the lining of the respiratory and digestive tracts. The squamous-cell carcinomas of different body sites can show differences in their presented symptoms, natural history, prognosis, and response to treatment. By body location Human papillomavirus infection has been associated with SCCs of the oropharynx, lung, fingers, and anogenital region. Head and neck cancer About 90% of cases of head and neck cancer (cancer of the mouth, nasal cavity, nasopharynx, throat and associated structures) are due to SCC. Skin Cutaneous squamous-cell carcinoma is the second most common skin cancer, accounting for over 1 million cases in the United States each year. Thyroid Primary squamous-cell carcinoma of the thyroid shows an aggressive biologica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neoplasm
A neoplasm () is a type of abnormal and excessive growth of tissue. The process that occurs to form or produce a neoplasm is called neoplasia. The growth of a neoplasm is uncoordinated with that of the normal surrounding tissue, and persists in growing abnormally, even if the original trigger is removed. This abnormal growth usually forms a mass, which may be called a tumour or tumor.'' ICD-10 classifies neoplasms into four main groups: benign neoplasms, in situ neoplasms, malignant neoplasms, and neoplasms of uncertain or unknown behavior. Malignant neoplasms are also simply known as cancers and are the focus of oncology. Prior to the abnormal growth of tissue, such as neoplasia, cells often undergo an abnormal pattern of growth, such as metaplasia or dysplasia. However, metaplasia or dysplasia does not always progress to neoplasia and can occur in other conditions as well. The word neoplasm is from Ancient Greek 'new' and 'formation, creation'. Types A neoplasm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computed Tomography
A computed tomography scan (CT scan), formerly called computed axial tomography scan (CAT scan), is a medical imaging technique used to obtain detailed internal images of the body. The personnel that perform CT scans are called radiographers or radiology technologists. CT scanners use a rotating X-ray tube and a row of detectors placed in a gantry to measure X-ray attenuations by different tissues inside the body. The multiple X-ray measurements taken from different angles are then processed on a computer using tomographic reconstruction algorithms to produce tomographic (cross-sectional) images (virtual "slices") of a body. CT scans can be used in patients with metallic implants or pacemakers, for whom magnetic resonance imaging (MRI) is contraindicated. Since its development in the 1970s, CT scanning has proven to be a versatile imaging technique. While CT is most prominently used in medical diagnosis, it can also be used to form images of non-living objects. The 1979 N ...
