• Assessment of the Relationship between Odontogenic Maxillary Sinusitis and Findings in the Ostiomeatal Unit on Coronal CT Images

抄録

Background and Objective: The ostiomeatal unit (OMU) incorporates the maxillary sinus ostium, infundibulum, uncinate process, hiatus semilunaris ethmoid bulla, middle turbinate and middle meatus. The maxillary ostium is located in the superior portion of the medial maxillary wall and drains into the posterior aspect of the ethmoid infundibulum. The detailed anatomy of the OMU as displayed by CT provides a road map for surgeons prior to endoscopic sinus surgery. However, little attention has been paid to the relationship between the OMU and odontogenic maxillary sinusitis. This study examined the relationship between the osteomeatal unit and odontogenic maxillary sinusitis using coronal CT images.<BR>Subjects and Methods: Materials consisted of 100 abnormal maxillary sinuses in 100 odontgenic maxillary sinusitis patients. Using coronal images, mucosal abnormalities were examined by grading expansion of the low density area, which represents the mucous membranes in the maxillary sinuses. Findings were classified into 3 types and the correlation between obstruction of the maxillary ostium and thickening of other sinonasal sinuses was examined.<BR>Results: Results of the grading were as follows: 25 maxillary sinuses were graded as type 1, 22 maxillary sinuses as type 2, and 53 maxillary sinuses as type 3. On pattern analysis using coronal CT images, there were significant differences in obstruction of the maxillary ostium based on thickening of the mucous membranes of the odontgenic maxillary sinusitis (p < 0.01); also there was a correlation between thickening of the mucous membranes of the ethmoid sinuses and thickening of the mucous membranes of the odontgenic maxillary sinusitis (p < 0.01).<BR>Thickening of the mucous membranes of both the ethmoid sinuses and frontal sinuses was well correlated with obstruction of the maxillary ostium on coronal CT images (p < 0.05). However, there was no correlation between obstruction of the maxillary ostium and sphenoid sinuses.<BR>Conclusion: Our study indicates that the severity of odontogenic maxillary sinusitis was well correlated with obstruction of the OMU on coronal CT images.
