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.
Odontogenic sinusitis is an inflammatory condition of the paranasal sinuses that is the result of dental pathology, most often resulting from prior dentoalveolar procedures, infections of maxillary dentition, or maxillary dental trauma. [6] Infections associated with teeth may be responsible for approximately 20% of cases of maxillary sinusitis ...
Maxillary sinusitis is common due to the close anatomic relation of the frontal sinus, anterior ethmoidal sinus and the maxillary teeth, allowing for easy spread of infection. Differential diagnosis of dental problems needs to be done due to the close proximity to the teeth since the pain from sinusitis can seem to be dentally related. [ 1 ]
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 ...
The maxillary sinus is known for its thin floor and close proximity to the posterior maxillary (upper) teeth. [ 1 ] [ 6 ] The extraction of a maxillary tooth (typically a maxillary first molar which lies close to the lowest point of antral floor although any premolar or molar can be affected) is the most common cause of an OAC (which can then ...
Sinus disease often occurs in conjunction with, and in other instances may contribute to the development of nasolacrimal duct obstruction. Patients should be asked about previous sinus surgery, as the nasolacrimal duct is sometimes damaged when the maxillary sinus ostium is being enlarged anteriorly.
A human skull contains two pterygopalatine fossae—one on the left side, and another on the right side. Each fossa is a cone-shaped paired depression deep to the infratemporal fossa and posterior to the maxilla on each side of the skull, located between the pterygoid process and the maxillary tuberosity close to the apex of the orbit.

The maxillary sinus is the most commonly involved. Fungi responsible for fungal sinusitis are Aspergillus fumigatus (90%), Aspergillus flavus, and Aspergillus niger. Fungal sinusitis occurs most commonly in middle-aged populations. Diabetes mellitus is the most common risk factor involved. [3]
