Mucous retention cyst in maxillary sinus indicated by the asymmetrical blue lump to the right of the nose. The most common location to find a mucocele is the inner surface of the lower lip. It can also be found on the inner side of the cheek (known as the buccal mucosa), on the anterior ventral tongue, and the floor of the mouth.
Maxillary sinus entry shown in red. The pyramid-shaped maxillary sinus (or antrum of Highmore) is the largest of the paranasal sinuses, located in the maxilla. It drains into the middle meatus of the nose [ 1 ][ 2 ] through the semilunar hiatus. It is located to the side of the nasal cavity, and below the orbit. [ 2 ]
Expansion of the cyst causes erosion of the floor of the maxillary sinus. As soon as it enters the maxillary antrum, the expansion rate increases due to available space for expansion. Performing a percussion test by tapping the affected teeth will cause shooting pain. This is often clinically diagnostic of pulpal infection. [citation needed]
Caldwell-Luc surgery, Caldwell-Luc operation, also known as Caldwell-Luc antrostomy, and Radical antrostomy, is an operation to remove irreversibly damaged mucosa of the maxillary sinus. It is done when maxillary sinusitis is not cured by medication or other non-invasive technique. The approach is mainly from the anterior wall of the maxilla ...
On an x-ray, cysts appear as radiolucent (dark) areas with radiopaque (white) borders. [7] However, cysts in maxillary sinus, also known as antrum, can appear radiopaque as the surrounding air absorbs fewer photons than the cystic fluid content. Cysts are usually unilocular, but may also be multilocular.
Classic symptoms of sinus disease such as headache, facial pain, purulent nasal discharge or nasolacrimal obstruction [12] may occur when maxillary sinus is involved. According to a study, 45.7 percent of dentigerous cysts involved mandibular third molar. [8] On the other hand, only 2.7 percent of dentigerous cysts involved the maxillary premolar.
Odontogenic sinusitis. Odontogenic sinusitis. Odontogenic sinusitis is a type of sinusitis (inflammation of the sinuses), specifically caused by dental infections or procedures. [1] Comprising approximately 10-12% of all chronic sinusitis cases, this condition primarily affects the maxillary sinus, which is in close proximity to the upper teeth.
Oral mucocele a mucous cyst. Oral mucoceles are common, and are caused by rupture of a salivary gland duct and spillage of mucin into the surrounding tissues. Usually, they are caused by trauma. Classically, a mucocele is bluish and fluctuant, and most commonly occurs on the lower lip. [11] Ranula is a mucocele under the tongue.
