Abstract
Objective: To assess the relation between the inflammatory changes in the maxillary sinus wall, including the alveolar process (bony lesions), and clinical symptoms of progressive odontogenic maxillary sinusitis as a means of elucidating the pathophysiology of the disease.
Patients and Methods: Thirty patients with odontogenic maxillary sinusitis were examined. The extent of bony lesions was evaluated on single photon emission computed tomography bone scintigraphy images and the extent of the inflammatory changes in the maxillary sinus mucosa spreading to the nasal and other paranasal sinuses (mucosal lesions) was evaluated by computed tomography. The relation between the extent of bony lesions and bone activity associated with causative maxillary alveolitis evaluated by single photon emission computed tomography bone scintigraphy data was assessed. The relationships of the extent of bony lesions and bone activity with the presence of facial inflammatory symptoms and the extent of mucosal lesions were also assessed.
Results: Bone activity was significantly correlated with the extent of bony lesions as well as the presence of facial inflammatory symptoms and the extent of mucosal lesions, which were also correlated with the extent of bony lesions.
Conclusion: Odontogenic maxillary sinusitis must be viewed as a bone disease in which bone activity caused by maxillary alveolitis is associated with the extent of bony lesions and thus affects the pathophysiology of the disease.
