What is sinus pathology?

Sinus pathology was defined as abnormal sinus X-rays, either on standard or tomography. Fifty-four percent of the X-rays were classified as abnormal based on mucosal thickening, loss of translucency of the cavities of polyps.

What are the most commonly seen maxillary sinus pathology?

In terms of frequency, the most frequent pathology was the unspecified sinusitis (44.4%), followed by polyps (18.2%), malignant tumours (9.8%), inverting papilloma (7.5%), fungal sinusitis (4.7%), cysts (3.7%), benign tumours (2.3%), mucocele (2.3%) and other lesions (1.9%).

What causes sinus Pneumatization?

The maxillary sinus maintains its overall size while the posterior teeth remain in function as the size expands with age, especially when posterior teeth are lost. This process is called pneumatization and is possibly the result of atrophy caused by reduced strain from occlusal function.

What is maxillary sinus disease?

Maxillary Sinusitis is the inflammation of the paranasal sinuses caused by a virus, bacteria, or fungus. The infection can also result after an allergic reaction – when the immune system attacks the healthy body cells. This infection may be associated with both bacterial and fungal infections.

What causes the sinus to become a pathologic cavity?

The blockage may result from intra-antral or intra nasal inflammation,polyp or neoplasm.the entire sinus thus becomes the pathologic cavity. As mucous secritions accumulate and the sinus cavity fills, the increase in intra-antral pressure results in thinning,displacement,and in some cases destruction of sinus walls.

Are there any other pathology of the maxillary sinus?

No other (mucosal) pathology of the maxillary sinus was noted. The lesion is a retention cyst. On coronal views (not shown), these cysts are most frequently found on the floor of the maxillary sinus. Fig. 7.3 c Retention cysts. c MRI, T2-weighted, axial.

What are the 5 main patterns of sinonasal polyposis?

Sinonasal polyposis pattern 1 polypoid masses in the nasal cavity and paranasal sinuses 2 bilateral maxillary infundibulum widening 3 convex ethmoid air cell walls 4 attenuation (change) the nasal septum and ethmoid air cell walls 5 +/- infundibular, ostiomeatal, sphenoethmoidal recess patterns depending on secondary obstruction

Can a panoramic radiography detect maxillary sinus disease?

While panoramic radiography can be used to detect maxillary sinus disease, it cannot be used to entirely exclude sinus pathology. Only the portions of the sinus that are within the image layer will be demonstrated.
