Maxillary sinusitis may also develop from problems with the teeth, and these cases were calculated to be about 40% in one study and 50% in another. [59] 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 ...
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 ]
In most cases of sinus barotrauma, localized pain to the frontal area is the predominant symptom. This is due to pain originating from the frontal sinus, it being above the brow bones. Less common is pain referred to the temporal, occipital, or retrobulbar region. Epistaxis or serosanguineous secretion from the nose may occur.
One symptom is a same-side nose blockage (unilateral nasal obstruction). [3] When an OAC or OAF is present, the passage to the maxillary sinus can results in infection and inflammation. [citation needed] This subsequently results in mucus build up presenting as a unilateral nasal blockage. Sinusitis may also be present as a pain in the middle ...
Silent sinus syndrome most often affects the maxillary sinus, usually with a collapse of the orbital floor. It may also affect the frontal sinus or the ethmoid sinus. When the maxillary sinus is involved, the inferior oblique muscle may be damaged. [1] The cause of silent sinus syndrome is not well understood.
They then enter the alveolar canals on the infratemporal surface of the maxilla, and, passing from behind forward in the substance of the bone, communicate with the middle superior alveolar nerve, and give off branches to the lining membrane of the maxillary sinus and gingival and dental branches to each molar tooth from a superior dental ...
