Otomycosis externa is a fungal infectious disease of the external auditory canal.
What Is The Cause Of Otomycosis
Fungi tend to grow and reproduce in warm and humid environment. Fungal infection is more common when water enters the external auditory canal or secretions are accumulated. Fungi such as penicillin, aspergillus and candida albicans are common.
Symptoms Of External Auditory Canal Mycosis
Itching in the ears, and some patients will feel very itchy, especially at night. During examination, the external auditory canal and tympanic membrane can be seen covered by a layer of yellow or white powder or villous lichen membrane. After removal, the affected area can be seen slightly reddening and damp. When co-infected with other bacteria, there will be symptoms such as earache and pus.
Some patients with milder infections may have no symptoms and are found abnormal only on examination.

The scab skin extracted from the ear canal was used as a smear, and 1–2 drops of 10% sodium hydroxide (potassium) solution was added, so that the hyphae and spores could be seen under the microscope. It can also be examined by fungal culture.

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.
