The mechanism behind contact lens-induced polymegethism is unknown, though it is also thought to be a byproduct of corneal edema and epithelial hypoxia. [2] Endothelial pleiomorphism is another factor that arises from long-term use of rigid gas permeable lenses; significant decreases in 6-sided cells are noted after one year, accompanied by ...

Specifically, it is an inflammation of the mucosal lining of the mastoid antrum and mastoid air cell system inside [1] the mastoid process.

The infection may be either subacute or acute and is characterized by itching in the ear, malodorous discharge, inflammation, pruritus, scaling, and severe discomfort or ear pain. The mycosis results in inflammation, superficial epithelial exfoliation, masses of debris containing hyphae, suppuration, and pain. [2] Otomycosis can also cause ...
