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. [2]

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 ...
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.
Maxillary sinuses. Frontal sinuses, seen with an oblique view. Ethmoidal cells. Sphenoid sinus, seen through the open mouth. Odontoid process, where if it is just below the mentum, it confirms adequate extension of the head. The frontal sinus may not show the frontal sinus in detail. [1]
Special views focusing on the orbit of the eye may be taken to investigate concerns relating to the eye. [8] CT scans are used by physicians specializing in treating the eye (ophthalmologists) to detect foreign bodies (especially metallic objects), fractures, abscesses, cellulitis, sinusitis, bleeding within the skull (intracranial bleeding), proptosis, Graves disease changes in the eye, and ...
[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.
CT scan in the coronal plane, showing the ostiomeatal complex (green area) The lateral wall of each nasal cavity mainly consists of the maxilla. However, there is a deficiency that is compensated for by the perpendicular plate of the palatine bone, the medial pterygoid plate, the labyrinth of ethmoid and the inferior concha.
