Nasopalatine Duct Cyst
The nasopalatine duct cyst (NPDC) occurs in the median of the palate, usually anterior to first molars. It often appears between the roots of the maxillary central incisors. Radiographically, it may often appear as a heart-shaped radiolucency. It is usually asymptomatic, but may sometimes produce an elevation in the anterior portion of the palate. It was first described by Meyer in 1914. The median palatal cyst has recently been identified as a possible posterior version of the nasopalatine duct cyst. Signs and symptoms Nasopalatine duct cysts usually present as asymptomatic palatal The palate () is the roof of the mouth in humans and other mammals. It separates the oral cavity from the nasal cavity.

Oral And Maxillofacial Surgery
Oral and maxillofacial surgery is a surgical specialty focusing on reconstructive surgery of the face, facial trauma surgery, the oral cavity (mouth), head and neck, and jaws, as well as facial cosmetic surgery/facial plastic surgery including cleft lip and cleft palate surgery. Specialty An oral and maxillofacial surgeon is a regional specialist surgeon who treats the entire craniomaxillofacial complex: anatomical area of the mouth, jaws, face, and skull, head and neck as well as associated structures. Depending upon the national jurisdiction, oral and maxillofacial surgery may require a degree in medicine, dentistry or both. Subspecialties In the U.S., oral and maxillofacial surgeons, whether possessing a single or dual degree, may further specialize after residency, undergoing additional one or two year sub-specialty oral and maxillofacial surgery fellowship training in the following areas: * Cosmetic facial surgery, including eyelid (blepharoplasty), nose (rhino ...

Median Palatal Cyst
The median palatal cyst is a rare cyst that may occur anywhere along the median palatal raphe. It may produce swelling because of infection and is treated by excision or surgical removal. Some investigators now believe that this cyst represents a more posterior presentation of a nasopalatine duct cyst, rather than a separate cystic degeneration of epithelial rests at the line of fusion of the palatine A palatine or palatinus (in Latin; plural ''palatini''; cf. derivative spellings below) is a high-level official attached to imperial or royal courts in Europe since Roman times.

Palate
The palate () is the roof of the mouth in humans and other mammals. It separates the oral cavity from the nasal cavity. A similar structure is found in crocodilians, but in most other tetrapods, the oral and nasal cavities are not truly separated. The palate is divided into two parts, the anterior, bony hard palate and the posterior, fleshy soft palate (or velum). Structure Innervation The maxillary nerve branch of the trigeminal nerve supplies sensory innervation to the palate. Development The hard palate forms before birth. Variation If the fusion is incomplete, a cleft palate results. Function When functioning in conjunction with other parts of the mouth, the palate produces certain sounds, particularly velar, palatal, palatalized, postalveolar, alveolopalatal, and uvular consonants. History Etymology The English synonyms palate and palatum, and also the related adjective palatine (as in palatine bone), are all from the Latin ''palatum'' via Old French ''palat ...

Purulence
Pus is an exudate, typically white-yellow, yellow, or yellow-brown, formed at the site of inflammation during bacterial or fungal infection. An accumulation of pus in an enclosed tissue space is known as an abscess, whereas a visible collection of pus within or beneath the epidermis (skin), epidermis is known as a pustule, pimple or ''spot''. Description Pus consists of a thin, protein-rich fluid (historically known as ''liquor puris'') and dead leukocytes from the body's immune response (mostly neutrophils). During infection, macrophages release cytokines, which trigger neutrophils to seek the site of infection by chemotaxis. There, the neutrophils release Neutrophil granule, granules, which destroy the bacteria. The bacteria resist the immune response by releasing toxins called leukocidins.Madigan, Michael T. and Martin, John M. Brock Biology of Microorganisms 11th ed. Pearson Prentice Hall. US. 2006: 734 As the neutrophils die off from toxins and old age, they are phagocytosi ...
