What are the symptoms of otitis externa?
summary
Otitis externa is caused by bacterial infection. It can be divided into diffuse otitis externa and localized otitis externa, and the latter can be called external auditory canal furuncle. The predisposing factors of diffuse otitis externa include ear tapping, skin damage, water intake during swimming, stimulation of suppurative otitis media pus, and invasion of some pathogenic bacteria, such as Staphylococcus aureus, Streptococcus and Pseudomonas aeruginosa. The localized otitis externa is mainly due to the localized suppurative infection of hair follicles or sebaceous glands. Let's take a look at the following.
What are the symptoms of otitis externa?
First, diffuse otitis externa can be divided into acute and chronic. Acute symptoms include ear pain, burning sensation, and a small amount of secretion outflow, as well as auricle traction pain and tragus tenderness. Chronic otitis externa has itching and a small amount of exudate.
Second: otoscopy can be carried out. When the ear is in severe pain, painkillers can be used. In the early stage of inflammation, local hot compress can be used. If there is no local suppuration, phenol glycerin can be used to drop the ear or fishstone glycerin gauze can be applied to the affected area. When there is secretion in the ear canal, it can be cleaned with acid salt water.
Third: the limitation of otitis externa can have severe pain, and in the mouth, eating and chewing when the pain will aggravate. When there is a furuncle in the ear, there can be hearing loss and tinnitus. If the furuncle is broken, there can be pus like outflow. Special attention should be paid to the ulceration of boils.
