The cause of this situation is usually a periapical or periodontal infection of a maxillary posterior tooth, where the inflammatory exudate has eroded through the bone superiorly to drain into the maxillary sinus. [59] An estimated 0.5 to 2.0% of viral rhinosinusitis (VRS) will develop into bacterial infections in adults and 5 to 10% in ...
Dental conditions such as gum disease, periapical abscesses, or tooth decay can lead to odontogenic sinusitis. Similarly, dental procedures such as tooth extractions, implant placement, or root canal treatments, particularly if they involve the posterior maxillary teeth, can also cause this condition.

The maxillary sinuses, the largest of the paranasal sinuses, are under the eyes, in the maxillary bones (open in the back of the semilunar hiatus of the nose). They are innervated by the maxillary nerve (CN V2). [2] The frontal sinuses, superior to the eyes, in the frontal bone, which forms the hard part of the forehead.
Recent studies have classified two types of maxillary sinus septa: primary and secondary. Primary septa are those initially described by Underwood and that form as a result of the floor of the sinus sinking along with the roots of erupting teeth; these primary septa are thus generally found in the sinus corresponding to the space between teeth, as explained by Underwood.
Antral lavage is a largely obsolete [citation needed] surgical procedure in which a cannula is inserted into the maxillary sinus via the inferior meatus to allow irrigation and drainage of the sinus. [1] It is also called proof puncture, as the presence of an infection can be proven during the procedure.

[5] [6] At the final phase of aeration, the floor of maxillary sinus is four to five milimetres below the floor of nasal cavity. However, timing of maxillary sinus growth is variable in different people. [5] The maxillary sinus can normally be seen above the level of the premolar and molar teeth in the upper jaw.
