disease and mucosal thickening: Aamong the 9 right-sided OMDs, 8 had ipsilateral MT.
Anatomical anomalies of the middle turbinate or ethmoid sinuses can obstruct the osteomeatal complex
and these patients can be more prone to sinusitis, especially if there is an added inflammatory condition.
Obviously, nasal polyps may cause obstruction of the osteomeatal complex
Studies have used the patient history, Lund-Mackay radiological score, and patency of the osteomeatal complex
to evaluate the significance of RCMs (2, 4, 7).
This osteomeatal complex
contributes to the final common drainage pathway of maxillary, anterior ethmoidal and frontal sinuses.
Nasal endoscopy plays a key role in identifying anatomical structural variations and mucosal changes of middle meatus and osteomeatal complex
causing drainage block leading to CRS both in patients with normal CT and in patients with abnormal scans.
Plain radiographs do not allow adequate evaluation of the osteomeatal complex
or of the sphenoid and ethmoid sinuses because of overlapping anatomic structures.
But while investigators have focused on the osteomeatal complex
and its relation to chronic rhinosinusitis, there has been little discussion of the superior turbinate.
 The origin of pathology in osteomeatal complex
also plays a significant role in the pathogenesis of rhinosinusitis.
The computed tomography (CT) scan showed a large mass filling the left maxillary sinus causing destruction of the sinus wall anteromedially and anterolaterally, osteomeatal complex
, and the hard palate.
(2) The primary predisposing factor is an obstruction of the osteomeatal complex
that leads to a hypoventilated maxillary sinus.
CT with its excellent capability for displaying bone and soft tissue is the current diagnostic modality of choice for evaluating the osteomeatal complex
. The development of functional endoscopic sinus surgery and its ability to alleviate disease in the osteomeatal unit allow treatment to be undertaken with minimal injury to adjacent normal structure.
Endoscopic removal of an ectopic third molar obstructing the osteomeatal complex
. Ear Nose Throat J 2001;80(9):667-70.
Hot and dry desert environment has lesser impact on the key osteomeatal complex
area and ethmoid complex.
Both polyps originated in the middle meatus and obstructed the osteomeatal complex
, and the mass on the right extended to the choana.
