What causes bone erosion in sinus cavity?

What causes bone erosion in sinus cavity?

In the case of AFRS, bone erosion is thought to be caused by pressure atrophy from the accumulation of fungal debris and the subsequent expansion of the paranasal sinus (PNS) walls and by the secondary effects of inflammatory mediators [5,8-11].

How do you fix a sinus sphenoid?

Acute sphenoid sinusitis can be cured with antimicrobial medication use alone,9 but a rule of thumb is that, if during the antibiotic therapy the symptoms get worse or continue for 24 to 48 hours or if there are signs of complications, surgery is indicated.

How can I drain my sphenoid sinus?

3. Sphenoid/ethmoid sinus massage

1. Place your index fingers on the bridge of your nose.
2. Find the area between your nasal bone and the corner of the eyes.
3. Hold a firm pressure in that spot with your fingers for about 15 seconds.
4. Then, using your index fingers, stroke downward along the side of the bridge of your nose.

Does fungal sinusitis show up on CT scan?

Allergic fungal sinusitis is the most common form of fungal sinusitis and is common in warm and humid climates. On imaging, it usually presents as opacification and expansion of multiple paranasal sinuses, unilaterally or bilaterally, with content that is centrally hyperdense on CT.

What are results of expansile lesions of the sphenoid sinus?

RESULTS: Of the seven patients with expansile lesions, vidian’s canal margin erosion was present in seven, unequivocal sinus expansion in three, wall erosion in three, wall thinning in three, erosion of the foramen rotundum in two, and flattening in the foramen rotundum in four.

Can a sinus infection cause extensive bone erosion?

The patient awoke from anaesthesia with complete resolution of his diplopia. Conclusion: Otolaryngologists should be aware that approximately 20 per cent of patients with allergic fungal sinusitis demonstrate paranasal sinus expansion and bone erosion involving surrounding anatomical structures.

Is there such a thing as a sphenoid sinus mucocele?

Previous reports of sphenoid sinus mucocele suggest that sinus expansion is one of the imaging findings supporting this diagnosis (1, 2). Nonetheless, the differentiation between sinus expansion and opacification of a developmentally asymmetric sphenoid sinus may be difficult in the absence of gross erosion of the sinus wall.

What is a bone window image of a sphenoid sinus?

Fungal process (mycetoma). A, Coronal computed tomographic image filmed with bone window technique demonstrates opacification of the left sphenoid sinus with marked thickening of the walls of the sinus suggesting a long-standing inflammatory process.
