Some patients with milder infections may have no symptoms and are found abnormal only on examination.

The Difference Between Otomycosis And Chronic External Auditory Canal Inflammation

Chronic otitis externa has only the sensation of discomfort or itching, and the skin of the ear canal is reddening or thickened and covered with pus crust but without the growth of mildew moss, which can be distinguished by bacterial culture or microscopic examination.

Otitis externa is acute or chronic inflammation of the skin in the external auditory canal. The patient feels itchy and burning sensation in the ear. Pain in the ear is felt only when the temporomandibular joint moves. At first, the secretion is a thin serous secretion which gradually becomes thick.

Fungal infection of the external auditory canal showed a bluish-smoke-colored, black or yellowish-white mold coating, with visible hyphae, and the area where it contacted the skin was in the shape of a crust.
