A boil is an abscess of the skin caused by an infection of one of the hair follicles located deep in the skin. After a few days, the first development of inflammation - necrosis of the hair follicle and partially surrounding tissues occurs, and gradually a cavity filled with pus forms in this place (t.
Ethmoiditis is an inflammation of the ethmoid sinus (ethmoid sinus). Often, the inflammation of the ethmoid sinus is called the generic term “sinusitis,” which should be understood to be the inflammation of any of the four pairs of sinuses. The paranasal sinuses (in addition to the ethmoid) also include the maxillary sinuses - their inflammation is called the term "antritis", the frontal sinuses - their inflammation is called "frontal sinus", the sphenoid sinuses - their inflammation is called sphenoiditis.
Sinusitis is an inflammatory disease of the maxillary sinuses located in the upper jaw (Fig. 1). Often this disease is also called "sinusitis." This is due to the fact that the maxillary sinuses in professional literature is often called the term "maxillary sinus". Sinusitis is most often unilateral, t.
Frontalitis is an inflammation of the frontal sinuses. The frontal sinuses are one of the four pairs of paranasal sinuses (there are still maxillary, ethmoid and sphenoid sinuses). The frontal sinuses are located in the frontal bone, immediately above the eyes (Fig. 1). The accessory sinuses (including the frontal sinuses) are cavities that are filled with air and lined from the inside with a mucous membrane.
Sphenoiditis is an inflammation of the sphenoid sinuses, which are one of four pairs of paranasal sinuses. Isolated sphenoiditis is extremely rare (1-2% of all cases of acute and chronic sinusitis). Most often sphenoiditis occurs as a result of inflammation in the adjacent ethmoid sinuses, which is called "ethmoiditis".
Some patients turn to the dentist with a question: a lump came out under my tongue or lip - what is it? It is nothing but a retention cyst of the lower lip or hypoglossal space. Cyst on the lip: A photo of a cyst can be located closer to the surface of the mucous membrane (as if rising above it), or it can be located deeper in the tissues.
A furuncle is a purulent skin abscess that occurs inside the infected hair follicle and usually proceeds with the formation of a large amount of pus and partial necrosis of the tissues surrounding the follicle. More often boils occur at a young age from 12 to 40 years. A boil on the face is formed much more often than on other parts of the body (according to statistics, approximately 65% of all boils are formed on the face).
