Ear canal discharge

Introduction When there is inflammation in the external auditory canal or middle ear, the phenomenon of pus in the ear canal can occur. Traditional Chinese medicine treats diseases with perforation of eardrum and pus in the ear as the main symptoms, collectively referred to as pus. Common causes are diffuse otitis externa, which is acute and chronic. When the external auditory canal skin trauma or local resistance is reduced, it is easy to develop. It is more common in the ear canal after swimming, self-earing, trauma, allergic diseases. Common pathogens are Staphylococcus aureus, Streptococcus, Pseudomonas aeruginosa and Proteus.

1. The purulent fluid flows out of the ear and may be accompanied by bleeding.

2. Audiological examination: manifested as varying degrees of conduction, mixed or sensorineural hearing loss.

3. Imaging examination: High-resolution CT of the tibia is an effective tool for evaluating the nature and extent of chronic suppurative lesions. Through imaging examination, we can understand the degree of gasification of the mastoid, the state of the small bone, the various parts of the middle ear and the extent of the lesion.

Differential diagnosis

Differential diagnosis of ear canal pus:

1, pus in the ear: chronic suppurative otitis media clinically characterized by repeated pus in the ear, tympanic membrane perforation and hearing loss. Anyone who is treated improperly for acute suppurative otitis media, has excessive bacterial toxicity, has weak body resistance or has mastoiditis, and is persistently pus for 1 to 2 months, and is called chronic suppurative otitis media. The incidence of this disease is relatively high. In recent years, there have been more than a thousand primary school students in the census, the incidence has changed from 0.5% to 4.3%, and the incidence rate of farmers surveyed in Shandong, Henan and Guizhou provinces is 1.6%. The incidence of primary school students in the UK is 0.9%. Most of the patients are young and middle-aged, and rarely occur after the age of 40.

2, ear discharge: ear discharge, also known as ear leak, refers to the accumulation of external auditory canal or liquid from the external auditory canal, is one of the common symptoms of ear disease. Occasionally it can be caused by lesions in adjacent tissues.

3, ear pus: ear pus is also known as ear leak, a common symptom of ear disease. When the ear is pus, attention should be paid to the nature, quantity and odor of the pus for identification. In the case of external auditory canal, there may be watery secretions. A purulent fluid flows out of the ear and may be accompanied by bleeding.
