In conclusion, sensitivity and/or specificity of all these diseases indicate the shortage or weakness of water's view technique to estimate and diagnose the soft tissue disease, bone erosion and osteomeatal complex of the sphenoid/ ethmoid sinuses and many of the findings and diagnosis are missed.
Endoscopic sinus surgery (ESS) is a common procedure which requires a meticulous assessment of patient and a detailed radiological description of the anatomy and its anatomical variations in nose and PNS.2 Although the role of anatomical variations of osteomeatal complex in the etiology of sinonasal disease is controversial3 but knowledge of these variations in every patient is important before surgery is planned to avoid damage to surrounding vital structures like the orbit and the brain.
There was complete opacification of the left maxillary sinus with obscuration of the osteomeatal complex. Expansion and thinning of the medial wall of the maxillary antrum was also noted.
(1,5) Sinusitis can occur as a result of either (1) an extension of a primary neoplasm into the maxillary sinus or (2) obstruction of the osteomeatal complex by the tumor.
Inflammation of the nasal cavity and osteomeatal complex (structures closely related to the middle meatus) can lead to obstruction of the small ostia that drain into this area.
The area that contains the drainage passages is called the osteomeatal complex (OMC).
By demonstrating that the osteomeatal complex is small, and focusing on obstruction rather than infection, I am able to avoid any confrontation about antibiotics entirely.
Since septal deviation causes lateral compression of the middle turbinate and uncinated process pushing them into the infundibulum and thus causes obstruction of osteomeatal complex. Deviation of the nasal septum was found in 35% of cases in the present study.
The presence of RCMs, osteomeatal complex obstruction (OMCO), an accessory ostium, and abnormalities of the middle turbinate (AMT) were evaluated independently for the right and left sides.
The osteomeatal complex and frontal recesses were blocked on both sides.
[1] The 'osteomeatal complex' of the middle meatus is a group of anatomical structures that includes principle and accessory maxillary sinus ostia.
